ICELAND MOSS - ACTUALLY A LICHEN: HEALTH BENEFITS AND USES OF ICELAND MOSS

ICELAND MOSS, CETRARIA ISLANDICA 

Iceland moss is a lichen and not a moss, and grows prolifically in Iceland, hence the name. It is in the Parmeliaceae family of plants and grows to a mere four inches high but has a spread of around two feet. 

It can be found in the Arctic, in Britain, particularly in Scotland, Northern England and North Wales, in North America and south western Ireland. It can be almost any colour in the spectrum from light grey through green to dark brown. Another name for Iceland moss is eryngo-leaved liverwort,.

  In traditional medicine it has been used for pulmonary complaints, peptic and duodenal ulcers and gastric problems. It has a soothing action on the mucous membranes and was used for coughs, bronchitis and other chest complaints as well as for food poisoning and T.B. It is also used to promote appetite. It is said to be good to stop vomiting and feelings of nausea too.

  Today it can be found as an ingredient in toothpaste, and as a baking ingredient. It can be dried and ground and used with wheat flour to make bread. It can also be used to make confectionary, in which case it is made into a jelly and combined with lemon, sugar, chocolate, or almonds. In the 19^th century it was drunk with cocoa sweetened with sugar for a really wholesome drink in cases of colds and flu.

  The whole herb can be used although it has some lichen acids in it which have to be leached out before using internally. This is a tedious process, involving pounding the dried herb to a powder and soaking it in lye or filtering it through ash. Alternatively a jelly can be made from the whole plant by boiling it in water and changing and discarding the water twice- much easier to do. This process removes the bitterness of the plant.

  In traditional medicine systems in Europe Iceland moss is used to treat cancer and as an antibiotic, demulcent (soother).and tonic for the stomach. It is also believed to be a galactagogue, which means that it increases the flow of breast milk in breast-feeding mothers. Externally it is used to treat excessive vaginal discharge, boils, impetigo and to heal stubborn wounds.    

   The German Commission E has approved its use for loss of appetite, inflammation of the mouth and throat, coughs, bronchitis and dyspepsia. The whole plant gives a brown dye, and the antibiotic principle from the plant is used in disinfectant. The plant has potent antioxidant properties and has been found to boost the immune system. A new polysaccharide was found in the plant in 1994 which showed “immunostimulating activity” in vitro (Planta Medica 1994 Vol. 60 (6) pp 527-8 “Immunologically active polysaccharide from Cetraria islandica” Ingolfsdottir, K. et al)

  It has been deemed safe for use because it has been traditionally used in medicine for centuries. Research still needs to be done to allay criticisms of the German Commission E’s decision                                                                                              

BLOOD FLOWER, PERHAPS AN AGENT THAT WILL ASSIST IN OUR FIGHT AGAINST CANCER: HEALTH BENEFITS AND USE OF BLOOD FLOWER

BLOOD FLOWER, MEXICAN BUTTERFLY WEED, ASCLEPIAS CURASSAVICA 

This flower is native to the South American continent although it has now spread throughout the tropics and subtropics. It is related to the common milkweed, and is in the Asclepiadaceae family, and is a relative of aak (Calotropis procera).

  The genus name Asclepias is in honour of the Greek god of medicine, Asklepius or Asklepios, who was the son of Apollo, but who was brought up by Chiron the centaur who trained him in the art of medicine. Unfortunately Asklepius angered Zeus the Father of the gods because he upset the balance and natural order of nature by bringing the dead back to life. He was killed by Zeus’ thunderbolt and became a constellation. Because of this association with the god of medicine, we understand that the genus was considered to have medicinal properties by ancient peoples.

    The beautiful flowers of this plant attract the Monarch butterfly which lays eggs on it and also hummingbirds. The different coloured flowers on the same flower head remind me of those of Yellow sage or Spanish Flag,(Lantana camara). The flowers bloom between June and October, giving way to downy seeds.

  The sap from these plants can cause dermatitis, but diluted and used to get rid of intestinal worms. It is poisonous if ingested. Although the plant is not native to Australia the Aborigines there use it to kill fish and believe it to be a love charm.

  The roots are used in traditional medicine systems for their anodyne (pain relieving properties) and extracts of the roots have been shown to have antimicrobial, antifungal and antibacterial. (“Evaluation of antimicrobial activity of root extract of Asclepias curassavica”, Hemavani. C. and B. Thippeswamy in Recent Research in Science and Technology 2012, Vol. 4 (1): pp.40-43)

They are insecticidal too, and were used to clear buildings of insects, particularly fleas.                                                          

  In the Ayurveda system of medicine in the Indian subcontinent the plant is used to promote sweating in fevers, to get rid of intestinal worms, as a purgative and emetic, (so the system is cleansed thoroughly by expelling excrement and vomiting) for stomach tumours, piles, and gonorrhoea. The milky latex is used to get rid of warts and corns.

  In traditional medicine in China it is used for fever, to improve blood circulation and control both external and internal bleeding. The whole plant is dried and then made into a decoction as a cardiac tonic, for tonsillitis, bronchitis and pneumonia as well as for urethritis, and both internal and external bleeding. The latex from the plant is used to inhibit Candida growth.In some countries it is substituted for sarsaparilla in medicine.

  The root has antioxidant properties and antibiotic ones according to the research evaluation mentioned above.

  Calotropin has been isolated from the plant and this is a cytotoxic principle in vitro against cancer of the nasopharynx. “Calotropin, a Cytotoxic Principle Isolated from Asclepias curassavica L.”; S Morris Kupchan, John R Knox et al in Science 25 Dec 1964: Vol. 146. no. 3652, pp. 1685 – 1686.

   It has been used to staunch bleeding and has styptic properties and this has been borne out by the following research which concluded thus: “Cysteine proteases from Asclepias curassavica latex exhibited strong pro-coagulant action and were found to be specific in its action (Thrombin like). This could be the basis for the use of plant latex in pharmacological applications that justify their use as folk medicine.” (Journal of Ethnopharmacology. 2009 May 4; 123 (1):106-9. “Thrombin like activity of Asclepias curassavica L. latex: action of cysteine proteases” Shivaprasad H. V. et al.)

  It has also shown to have some Chemopreventive properties as outlined in ”Chemopreventive potential of β-Sitosterol in experimental colon cancer model - an In vitro and In vivo study” by Albert A Baska, Savarimuthu Ignacimuthu, Gabriel M Paulraj and Khalid S Al Numair in BMC Complementary and Alternative Medicine 2010.

  This plant clearly has some potential health benefits for us, as more research will doubtless show. It is not only here for the benefit of the Monarch butterfly.

JOINTFIR OR MORMON TEA PLANT: PROBABLY DOES NOT CONTAIN EPHEDRINE: HEALTH BENEFITS OF MORMON'S TEA

MORMON TEA PLANT, JOINTFIR, EPHEDRA NEVADENSIS 

The evergreen shrub known as Jointfir, or Mormon Tea plant is native to the south-western US. As the Mormons are not allowed to drink coffee because it is a stimulant (containing, as it does, caffeine) the twigs of this plant are used to make a tisane or tea, hence the name. The plant does not have leaves as such but has spiky green twigs, which resemble a fir tree’s needles (for example those of the European silver fir).

  The flowers are reminiscent of those of the Greek mountain tea plant, and these bloom in April through to the end of June. The fruit is a smooth brown nutlet which can be cooked although it tastes bitter, and it may be roasted and ground to make flour for using in making bread.

  This plant is in the Ephedraceae family, making it a close relative of the Sea grape, Ephedra distachya. Because it is in the Ephedra genus, it was supposed that it has the same properties as other plants in that genus; but it seems that this is not the case. This plant contains no, or very few, Ephedra alkaloids, according to the European Food Standards Agency’s (EFSA) report of 2009. That being the case, most of what has been written about the plants’ psychoactive properties online is probably not true.

  Mormon tea is made by taking the twigs of the plant and infusing them to make a tea or tisane. Both the fresh and dried twigs can be used, and for drying purposes the green twigs can be harvested at any time of the year.

  Traditionally the tea was made by Native Americans who used it medicinally as a blood purifier, diuretic and to lower the temperature of the body during fevers. It was also used as a general tonic and for kidney, urinary-genital problems and STDs.

  The plant does not contain ephedrine, or at least, not much, so all the literature regarding this compound does not apply to this particular member of the Ephedra genus.            

  The fruit from the plant can be eaten raw, although it is a little bland, but sweet, and the twigs can be chewed to treat the symptoms of asthma, but not the root cause. It makes respiratory problems easier, but does not cure them.

  There are rarely any side effects if you drink Mormon tea in moderation, although you may experience some if it is drunk to excess.

  The plant does contain the compounds, kynusenates, which have antimicrobial properties, and it is a very effective diuretic and because of this property, it can contribute to weight loss.

MOLE PLANT, CAPER SPURGE - NOT RECOMMENDED FOR MEDICINAL USE: HISTORY OF HEALTH BENEFITS AND USES OF MOLE PLANT

MOLE PLANT, CAPER SPURGE, EUPHORBIA LATHYRIS 

The mole plant is so named because it was believed that it deterred moles and other creatures from making a mess of a garden. For the same reason it is called gopher plant in North America. It is a member of the spurge or Euphorbiaceae family which make it s close relative of petty spurge, poinsettia, the Candlenut tree, jamalgota (Croton tiglium), the castor bean plant, yucca, and both French and Dog’s mercury.

  The whole plant is toxic and should be treated with caution. Despite this it has been use in traditional medicine systems in the past. The name ‘spurge’ comes from the Middle English and Old French, ‘espurge’ which means to purge, thus showing what these spurge family plants were traditionally used for in terms of medicine. The mole plant is native to Europe and possibly to Britain, although it may have been a garden escapee there and become naturalized.                                                                                                       

   French people living in rural locations were said to take 12–15 seeds as a purgative, perhaps similar in action and toxicity to castor oil or perhaps even to jamalgota. However one seed is sufficient as a mild laxative. The root is also used as a purgative and emetic (to produce vomiting and so cleanse the system). The leaves and sap or latex from the plant, are vesicant, and have been used by beggars so that they produce blisters and weeping sores which meant that they aroused more sympathy and so got more money. The latex was used in folk medicine for cancers and to remove corns and warts.  It is also said to have antiseptic and diuretic properties. In the past the mole plant was used for diarrhea, gangrene, melanoma, skin ailments, sores, and sore throats. The seeds are used in homeopathy for erysipelas, paralysis, and rheumatism. The seed oil is applied to burns, however this is not recommended.

  The seed is also said to have the ability to kill parasites. The fresh seeds have been used to treat cancerous tumours and leukaemia, and the oil is antiseptic.

  The plant is in flower between May and June and the seeds ripen in July and August. The seeds need to be steeped in salted water for days before using and then pickled in vinegar to be used as a caper substitute, however given their toxicity it is not recommended that they are used.

  The Nobel Laureate, Melvin Calvin believed that the oil from this plant could be used as fuel and used in refineries without too many problems. He first stated this in 1976, but the plant has not been used for fuel yet.                                    

  The latex from the plant has reportedly been used as a depilatory, but given the irritancy caused by this latex it is not advisable to put it on the skin.

  This is a plant that should not be used medicinally, or for food; this post is for information only.

DYER'S BROOM, DYER'S GREENWOOD - POSSIBLE CANCER GROWTH INHIBITOR: HEALTH BENEFITS AND USES OF DYER'S BROOM

DYER’S BROOM, DYER’S GREENWOOD, GENISTA TINCTORIA

Dyer’s broom is native to Britain, Europe, and the Mediterranean region and West Asia. It may be native to the north eastern USA, but is probably an escapee, as it was grown as an ornamental. It grows to around two feet tall with a spread of more than three feet. It has narrow pointed leaves and yellow flowers which bloom between June and September. The seeds ripen between August and October. The plant is pollinated by insects and spring open rather explosively when an insect touches them.

   The plant is closely related to broom, and is a member of the Fabaceae or Leguminosea family, the pea or bean family of plants. This means that it is related to the pongam tree, the cancer bush (Sutherlandia frutescans) the lead tree or ipil-ipil, the Indian Coral tree, the Monkey Pod tree, the tree from which we get Gum Tragacanth or gond katira, jhand the mesquite tree, dhak or Flame of the Forest tree, the Pacific teak tree, the ashoka tree (Saraca indica), European laburnum, the Burmese rosewood tree, lupins, indigo, field restharrow, carob, melilot or sweet clover, milk vetch, the hyacinth bean, alfalfa, the butterfly pea,  chickpeas, borlotti beans and lentils just to name a few of its relatives. 

  All parts of the plant produce a yellow dye, but the flowering tops produce the best golden yellow one. This was traditionally used to dye woollen cloth and when mixed with woad can produce a green dye, and has been used for dye since ancient times, with both the Romans and Greeks using it.

  In 1708 Joseph Pitton de Tournefort (1656-1708) a French botanist, described its use on what is now the Greek island of Samos in the Dodecanese. He had been sent on an exploratory expedition to the Levant by the King of France, Louis XIV.

  However the plant was also used for medicine and in the 14^th century was, like broom, included in the ointment “unguentum geniste”. It was recommended for “alle could goutes” and the seeds and flowering tops have diuretic properties as well as being able to provoke vomiting to cleanse the system. They are also fairly strong laxatives, although not as strong as jamalgota (Croton tiglium).

  A decoction of the plant used for gout and rheumatism, while the seeds was ground and made into a plaster for broken limbs. In the Ukraine it was traditionally used to treat mad dog bites or rabies, but there is no scientific evidence to support the use, and neither is there evidence that it worked.                                              

  What is certain is that the plant is a good nitrogen-fixer so it can help the soil stay or become more fertile. The leaves are edible and can be used in soups and stews, as a vegetable, while it is said that the seeds can be roasted then ground to make a coffee substitute. The young flower buds can be pickled and used as a capers substitute too. The strong fibre from the stems can be made into coarse cloth or made into ropes.

  Care should be taken with the use of Dyer’s broom as it constricts the blood vessels and so increases blood pressure. It should be avoided by those with high blood pressure. It is best to harvest the plant when the flowers are about to bloom and dry it for later use.

  A tisane (infusion) of the flowering tops or the whole aerial parts of the plant can be a useful diaphoretic, promoting sweat in fevers, and it is also said to be a stimulant.

  Nicholas Culpeper, the English herbalist, writing his Herbal in the 17^th century has this to say about dyer’s greenwood or Dyer’s broom: -

“Government and virtues. Matthiolus says, That the root hereof cures tough phlegm, digests raw phlegm, thins gross humours, dissolves hard tumours, and opens obstructions. Some do highly commend it against the biting of venomous creatures, to be taken inwardly and applied outwardly to the hurt place; as also for the plague or pestilence. The people in some counties of this land, do use to bruise the herb, and lay it to cuts or wounds in the hands or legs, to heal them. “

  Interestingly the plant contains genisten which was first isolated from Dyer’s broom in 1899. This blocks the formation of new blood vessels and may block the uncontrolled cell growth associated with cancers, according to some scientists. It has been seen to inhibit the growth of prostate cancer, so perhaps this is a plant to watch in the future.

IRONWORT- MOUNTAIN TEA PLANT: SCIENTIFIC EVIDENCE SUPPORTS THE TRADITIONAL USES OF IRONWORT : MOUNTAIN TISANE RECIPE

IRONWORT, MOUNTAIN TEA, SIDERITIS SYRIACA 

If you have ever had a cold or flu in Greece, and have Greek friends, then you will know all about Greek mountain tea, which comes from this plant. It is called “malotira”  (better) in Crete, and is served in small cups or glasses in Turkey, with sugar or honey and  lemon to flavour it. Sideritis plants grow throughout the Balkan region and can be found in temperate Asia and Central Europe, but Sideritis syriaca comes fro the Mediterranean region as the name syriaca, from Syria might suggest.

  The genus name Sideritis means he who has iron, which is a reference to those who had been wounded in ballet by iron weapons. The plants were used as a wound healer although other suggest that the plant got its name because the flowers or sepals, look rather like spear tips.

  This mountain tea plant is in the mint family, the Lamiaceae or Labiatae family which means it has a whole host of relatives, which include, purple, yellow and white dead nettles, marsh woundwort, the teak tree, marjoram, basil, Holy basil, oregano, savory, thyme, lavender, lemon balm, Scarlet bee balm as well as bugle, motherwort, self-heal, catnip, the chaste tree, the small-flowered chaste tree, sage, ground ivy, Jupiter’s sage, wall germander, horsemint, Fragrant premna and hyssop.

  The plant can grow to heights of more than a foot, and is best gathered in July when it is in full bloom and then dried for later use. In Greece, you can buy it in street markets in bundles, or in supermarkets in jars.

  The essential oil has anti-microbial, antibacterial and antifungal properties and can be used for such ailments as candida in the same way as you would use Australian tea tree oil.

  In clinical trials this plant has been found to have antioxidant properties and to prevent and / or inhibit the growth of cancerous tumours. It also has anti-inflammatory and analgesic actions as indicated in “Preliminary evaluation on anti-inflammatory and analgesic effects of Sideritis syriaca L. herbal extracts.” Menghini L, et al. 2005 Summer; Vol.8 (2):pp. 227-31. Journal of Medicinal Food. They conclude: -                                                                                          

 “The data from this preliminary study reveal interesting pharmacological properties of S. syriaca L. herbal extracts related to the marked analgesic activity and the absence of gastric ulcerogenic activity. The same is for anti-inflammatory activity, but in this case it seems to be related only to the apolar fraction.”

  In Turkey the tisane is used for coughs and as a diuretic to rid the body of excess fluid.

  So far the plant has only attracted researchers from the areas in which it grows naturally, although the tea is sold in Germany as “Bergtee” and is becoming ever more popular. I can vouch for the fact that it helps in colds and flu and scientists say that it can do this because it has immune system boosting properties. It tastes fine, so is good to try if you have a cold, cough or flu.

                  

MOUNTAIN TEA RECIPE                                                                      

Take some sprigs of the dried herb (about 3 per cup) and pour boiling water over them.

Leaves for 10 minutes and add honey (or sugar) and a slice of lemon, or squeeze fresh lemon juice into the cup.

This has Taste and is a Treat(ment).

BITTER OR ROCKET CANDYTUFT, MEDICINAL PLANT WITH MANY NAMES: HISTORY AND HEALTH BENEFITS OF ANNUAL CANDYTUFT

BITTER, ANNUAL OR ROCKET CANDYTUFT IBERIS AMARA

Bitter candytuft is native to western and southern Europe including the British Isles. It grows amongst grain crops, such as wheat and oats, although its conservation status is of concern in some parts of Europe. It is a member of the Brassicaceae or Cruciferae family so is related to broccoli, brussel sprouts, kale, savoy cabbage, red cabbage, horseradish, mooli, garden cress, cauliflower, kohlrabi, mustard, field penny-cress, rocket, wallflowers, Dame’s rocket, Lady’s smock, Lamb's ears, wood betony, scurvy-grass, turnips and swede and a whole host of other plants, all of which could be used to prevent scurvy.

  All parts of the plant were used in medicine, but the seeds were especially valued. These can also be ground to a powder, and mixed with cold water can form a bitter, pungent mustard substitute. If mixed with hot water or vinegar or salt, the ‘mustard’ that is produced is milder.                                                                                                 

  The seeds have been used traditionally as treatments for asthma and bronchial problems, and the whole plant has been used against rheumatism and arthritis. It was considered good to relieve flatulence and the bloating that can be caused by the buildup of gas in the system.

  A homeopathic remedy is made from the plant to treat those who are nervous and agitated as well as people with liver and heart problems. It was formerly believed to be good for an ‘over-excited’ enlarged heart.

  An extract of the plant has shown to have an anti-ulcer effect on animals in vivo, and to soothe the smooth muscles of the smooth intestine and stomach in rats. (Iberis amara L. (bitter candytuft) – profile of a medicinal plant, Reichling J. and Saller R., 2002 in Research and Complementary and Natural Classical Medicine Supplement pp.21-33.)

   Bitter herbs have been used since ancient times to aid the digestion process and digestive system, and a herbal preparation was patented in Germany in the 1960s, called Iberogast, which is said to be effective against Irritable Bowel Syndrome, (IBS) and other stomach problems. It comprises extracts of bitter candytuft (from whose genus it gets part of its name), angelica root, chamomile, liquorice root, peppermint, lemon balm, caraway seeds, milk thistle, and celandine.

  There is little research into this wild herb, but it is becoming a favourite among gardeners which may be a good thing for its conservation status.

PARAGUAYAN HOLLY TREE, PRODUCER OF YERBA MATE: HISTORY AND HEALTH BENEFITS OF YERBA MATE

PARAGUAYAN HOLLY TREE, YERBA MATE ILEX PARAGUARIENSIS

Yerba maté is a popular drink all around the world these days, and it comes from an evergreen tree that is closely related to the British (or European) holly tree Ilex aquifolium. Like this holly the Paraguayan or South American one starts like as a shrub, but can grow up to 18metres tall. In the wild it grows with Araucaria species, which include the Monkey Puzzle tree. However it is classed as near threatened in the IUCN red list.

  A Spanish explorer, Juan de Solis, who is famous for exploring the La Plata River, stated that the Guarani Indians made a drink which “produced exhilaration and relief from fatigue” in his expedition in the 16^th century. Other Spaniards liked the drink too and the Jesuits started the first cultivation of wild plants of Ilex paraguariensis. By 1670 they had maté plantations. When the Jesuits were expelled from the Spanish lands in South America in 1767, Ilex paraguariensis stopped being extensively cultivated.                                             

  Today there are plantations but the years of harvesting the leaves from the trees and young shrubs had already taken its toll on the plants. The tea made from the leaves has been also called Jesuits’ tea and Paraguayan tea.

  Other Ilex species leaves are sometimes added to yerba maté and this accounts for the different tastes and properties of the tea drunk. Although yerba maté is now believed to have many health benefits, it has been found that heavy drinkers of the beverage have an increased risk of developing upper aerodigestive cancers, particularly oropharyngeal cancer. Despite this people still drink it copiously.

  Traditionally the beverage was drunk from gourds, particularly those of Langenaria vulgaris which in Quechua are called mathi- which is how we get the name maté, with yerba meaning herb. The leaves and twigs are dried and heated, and packed into the gourd, and then boiling water is poured over the leaves and they are allowed to infuse. Today yerba maté is brewed in gourd-shaped bowls and drunk through a metal ‘straw' with holes in the bottom of it which act as a strainer so you don’t get the leaves in your mouth. There are yerba maté bars throughout South America, just as there are coffee bars in Europe and North America.

  Despite its popularity around the world, there is not as much research on yerba maté as there is on coffee and green tea. However it seems that it can help manage obesity and lowers LDL-cholesterol. It has mild laxative properties and is also a diaphoretic so promotes sweating just as tea does. It is also a diuretic, so can help people who need to get rid of excess water because of other ailments.

  Yerba maté contains caffeine so it is a stimulant and the old Spaniards were right, it does dispel fatigue and stimulates the central nervous system. It is also a nutritious drink containing vitamins A, C, E and the B-complex vitamins B1 niacin, B2 riboflavin and B3 niacin as well as B5. As for minerals it contains aluminium, chromium, copper, iron, manganese, nickel, potassium and zinc along with 18 amino acids.

  The drink is said to enhance the memory functions and delay the aging process. It also stimulates digestion, and provides mild pain relief. A poultice of the leaves is used for anthrax ulcers, and is probably effective due to the tannin content of the leaves and their astringent properties.

 In Germany yerba maté has been approved for relief of mental and physical fatigue, and in France for weakness, or lack of energy. It is in the British Herbal Pharmacopoeia of 1996 for the relief of headaches, and fatigue as well as for weight loss. In one of the traditional systems of medicine of the Indian subcontinent, Ayurveda, yerba maté is prescribed for headaches, nervous depression, fatigue and the pains of rheumatism.

  Research is still continuing on yerba maté to discover what health benefits it actually has.

 

CREOSOTE BUSH IS NOT RECOMMENDED FOR INTERNAL USE AS MEDICINE: HISTORY AND POSSIBLE FUTURE HEALTH BENEFITS OF CREOSOTE BUSH

CREOSOTE BUSH OR CHAPARRAL, LARREA TRIDENTATA   

The creosote bush is so named because after a rainfall it smells like a wooden telegraph pole that has been treated with pitch. However commercial creosote does not come from this plant. It is native to the arid areas of the US and Mexico and has its homes in deserts and canyons. It is a member of the Zygophyllaceae family, so is a relative of Guaiacum officinale from which we get lignum vitae, puncture vine (Tribulus terrestris) and Syrian rue, among other plants.                                                

  Like the Jurupa oak it can boast of being one of the oldest living organisms on the planet as one clone range of plants in the Mohave Desert, has been dated to around 11,700 tears old. The plant splits its crown when it is between thirty and ninety years old and produces clones of itself, and all the plants have come from just one seed.

  It was much used by Native Americans as a medicinal plant, but it also useful as it can absorb chromium from the soil it grows in. However nothing can grow near it as it is very competitive in terms of the water it needs. Plants growing under it can only survive for a limited time due to the highly toxic substances it produces at root level.

  The plant can cause contact dermatitis and is thought to be toxic to the liver, and for this reason its internal use has been banned by the US Food and Drug Administration. However it contains Norhydroguaiacetic larreic acid (NDGA) which, before synthetic antioxidative materials were produced, was added to processed meats to prolong their shelf-life.

  NDGA is currently being researched to discover its potential in treating HIV/AIDS and cancers, among other diseases. It is a powerful antioxidant, anti-inflammatory agent, anti-tumour and anti-microbial.

  The plant possesses antiviral properties and is successful in treating herpes, and is anti-inflammatory, helping with rheumatism and arthritis and other inflammations.                                       

  The Native Americans used it for a number of diseases, including colds, as an expectorant in chest complaints, for cancer, toothache (they dripped the hot resin from the young twigs onto the tooth or place where the tooth ached) and a paste made from the leaves was used to heal wounds, lesions and bruises.

  A decoction of the leaves was given for diarrhoea and stomach problems. To allay thirst, the twigs may be chewed, if you are in the heat of the desert. The resin from the leaves and twigs is helpful in that it can prevent other fats or oils from turning rancid, or it can at least delay that process. It can also be used as a massage oil (if you like the smell), and can also provide some protection from the sun’s harmful rays.

  The flower buds can be pickled in vinegar and used as a substitute for capers. The plant can also be used for animal fodder, and is used to make roofing material for adobe dwellings. The twigs and leaves were washed and sun-dried to make a tisane, but the internal use of the plant is not to be recommended.

CASSABANANA OR MUSK MELON: HISTORY OF USES AND POTENTIAL HEALTH BENEFITS OF CASSABANANA

CASSABANANA, SICANA ODORIFERA NAUD.

The cassabanana is a rather strange-looking fruit which, when black or dark purple looks like a huge aubergine, although they are not related. Nor, as the name might suggest is this fruit in any way related to the banana. In fact it is a member of the Cucurbitaceae family, so is a relative of the kiwano or horned melon, honey melons, watermelons, butternut squash, bottle gourds, the ash gourd or petha, cucumbers, courgettes, and marrows to name just a few of its relations. It is the only plant in the Sicana genus, although sometimes it is known by its botanical synonym, Cucurbita odorifera Vell.

  It grows on a vine like other melons, although it needs strong support as the fruit is hefty. (It reminds me of that of the sausage tree, Kigelia africana) The fruit is also called the musk melon, because of its aroma. It is grown as an ornamental as well as for its fruit.

  It is believed to have originated in Brazil and spread throughout South America and tropical North America from there. There is archaeological evidence to show that it was being cultivated in Ecuador before the arrivals of the Spanish conquistadores. It was first documented by Europeans in 1658, as being cultivated and a popular fruit in Peru.

  Interestingly, it is used in Northern Peru to protect against jealousy. The remedy is to take the plant material (perhaps the whole plant) and sleep with it for seven days and nights, being sure to wash it every morning. After the stipulated period of time it needs to be disposed of in a “far away” place where it can’t be found by others. (“Healing the body and soul: Traditional remedies for “magical” ailments, nervous system and psychosomatic disorders in Northern Peru” Rainer W. Bussman et al. September 2010, African Journal of Pharmacy and Pharmacology, Vol. 4 (9), pp 580-623.)                                                                       

  The fruit is eaten raw and is cooling and refreshing during the hot months of the year. It is also used to make jams and preserves. The immature fruit is used as a vegetable and added to soups and stews.

  The fruit is nutritious, containing the minerals calcium, phosphorous and iron, along with carotene (which explains the colour of its flesh), and the B-complex vitamins, B1 thiamin, B2 riboflavin and B3 niacin, as well as vitamin C in the form of ascorbic acid.

  It is believed to be a moth repellent and kept with linen and clothes rather as we used to hang lavender in wardrobes, for its long-lasting aroma. During Holy Week (Easter) the fruit can be found decorating church altars too.

  In some countries it is used for sore throats, seeds are strung into necklaces and at the same time, the fruit is sliced and steeped in sugared water overnight, so that it begins to ferment, and then the water is sipped frequently to get rid of the sore throat, and the fruit that has been steeped in the sugared water may also be eaten.

  In Brazil an infusion of the seeds is used for fevers, as a laxative to get rid of intestinal worms, and as a purgative. The leaves are used for STDs for uterine haemorrhages and other complaints.                                                     

  In Yucatan, a decoction of the leaves and flowers is used as a laxative, for worms and as an emmenagogue, although the dose is small as these parts of the plant contain hydrocyanic acid.

  There are anthocyanins and flavonols in the rind of the cassabanana which means it has antioxidant actions (Jaramilla K. et al., Journal of Agricultural and Food Chemistry, 2011 Vol. 59 (3) pp975-83 “Identification of antioxidative flavonols and anthocyanins in Sicana odorifera fruit peel”)

  Anthocyanin-rich fruit are currently being investigated for their potential cancer-inhibiting properties, so perhaps this fruit has a lot more to offer us than simply being a cooling fruit to eat in summer.

LAMB'S EARS OR WOOLLY BETONY: HEALTH BENEFITS AND POSSIBILITIES FOR FUTURE TREATMENTS

LAMB’S EARS, WOOLLY BETONY, STACHYS BYZANTINA 

As a member of the Stachys genus (there are between two and three hundred species in this genus) Lambs’ ears or woolly betony is related to wood betony (Stachys officinalis).A synonym for this genus is Stachys lantana.

It gets both names because of the silky grey or white hairs that cover the aerial parts of the plant. It is a member of the Lamiaceae or Labiatae family or mint family, making it a relative of to purple, yellow and white dead nettles, marsh woundwort, the teak tree, marjoram, basil, Holy basil, oregano, savory, thyme, lavender, lemon balm, Scarlet bee balm as well as bugle, motherwort, self-heal, catnip, the chaste tree, the small-flowered chaste tree, sage, ground ivy, Jupiter’s sage, wall germander, horsemint, Fragrant premna and hyssop along with many other plants.                              

  In the past its leaves were used as a bandage to staunch the flow of blood from a cut and it is reportedly good to stop the pain of a bee sting. Other betony plants were used much more extensively than this one it would seem, as it has been cultivated in temperate parts of the world for centuries. It has more importance in the traditional systems of medicine in the countries to which it is native, no doubt, and those are Turkey, Armenia and Iran.

  It flowers in June through to September, and has white or pink or mauve flowers. It is an evergreen although it might die back if the winter is a particularly cold one.

  It has been discovered that the aerial parts of lamb’s ears have antioxidant, antibacterial and antimicrobial properties, so this supports its use as a wound healer. Phenolic compounds have been found in it along with tannins and flavonoids. Its essential oil is rich in sesquiterpenes for example a-capaene and spathulenol, both of which are used in the perfume industry, and beta-carophyllene which is also a component of clove oil. This last substance is a dietary cannabinoid and the first to be approved by the US food and Drug Administration (USFDA) as a food additive. It seems to have a local anaesthetic action and is anti-inflammatory, antibiotic, and according to some studies has anti-cancer properties.                         

  Spathulenol may have immunomodulatory effects, but more research need to be carried out on Lamb’s Ears so that scientists can ascertain what health benefits this plant has to offer us.
