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.

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.
