AFRICAN TULIP TREE - ONE WITH MANY USES: HEALTH BENEFITS AND USES OF THE AFRICAN TULIP TREE

AFRICAN TULIP TREE, SPATHODEA CAMPANULATA 

The African tulip tree is a fast growing evergreen which can reach heights of 35 metres. It is known as the fountain tree, Uganda Flame tree, the Nandi or Nile Flame tree, and the Squirt tree, among other names. It is indigenous to tropical Africa, although it is grown ornamentally in many countries with tropical climates around the world.

  It is the only member of the genus Spathodea but is a member of the Bignoniaceae family which makes it a relative of the Sausage tree (Kigellia Africana) and the trumpet vine (ishq pechaan bail). It has a flowering period of between five and six months, and produces edible seeds with transparent wings. It is used as a boundary fence and living hedge and the flowers yield a dye which varies in shades but which can be used to dye silk.

  It is called the Squirt tree because the flower buds contain a watery liquid which children utilize by piecing the buds and using them as water pistols. The hard central part of the fruit has a more sinister use however, as it contains a poisonous substance which is used on hunters’ arrows to kill prey. It can be used in coffee plantations to provide shade for the young plants.

  The timber from the tree is soft and used to make carvings and drums, but the tree has many medicinal applications, most of which have been supported by medical research. A decoction of the bark is astringent and used as a laxative as well as for cases of dysentery and for other gastro-intestinal problems. A decoction of the bark and leaves is used as a lotion for inflamed skin and on rashes. The flowers can be applied directly onto wounds, as can the bruised leaves which have mild pain-killing and anti-inflammatory properties. Both the bark and leaves have been found to have antiseptic actions.

  An infusion of the leaves is used for urethral infections, and the dried and pulverized or even the fresh inner bark is applied to oozing ulcers. The tree also has UV absorbing properties and could be utilized as a cheap sunscreen.

  Studies have found that the stem bark can lower blood sugar levels and so the traditional use of the bark for diabetes sufferers seems to have been borne out. (Journal of Phytotherapy Research, 1993 Vol. 7 (1) pp 64-69 Niyonzima, G. et al. Hypoglycaemic Activity of Spathodea campanulata stem bark decoction in mice.”) Extracts of the bark, leaves and roots have also been used to combat malaria and HIV and have antimicrobial and antifungal properties.

  It would appear that many of the traditional folk medicine uses of this tree have their basis in scientific theory.

OREGON GRAPE - STATE FLOWER OF OREGON: HEALTH BENEFITS AND USES OF OREGON GRAPE

OREGON GRAPE, SOURBERRY, MAHONIA AQUIFOLIUM 

The Oregon grape is the state flower of Oregon State in the US to which it is native. It is also native to northern California, northern Idaho, British Columbia and Washington State. It is a member of the Berberidaceae family, which makes it a relative of the Common barberry, Rasout, and Kashmal or the berberry. It was introduced into Britain as an ornamental in 1823 and has since managed to have naturalized in some parts as a garden escapee.

  This plant can grow to around 3 metres or approximately 9 feet high, and is fast-growing with shiny evergreen leaves which resemble a holly leaf, although the upper sides of these may turn a purple colour in winter. Because of its leaves it is also known as the holly-leaves barberry. It is known by several botanical names too, namely: - Berberis aquifolium, Berberis piperiana, Mahonia piperiana but the generally accepted name is Mahonia aquifolium.  Its flowers are bright yellow and smell a little like honey, and these give way to the fruit which ripens from green to blue-black growing in clusters like small grapes, making them easy to collect. These fruit can have between zero and nine seeds in them.

  The fruit contains quite a lot of vitamin C, making it good for colds and flu, but it tastes rather sour, hence the name sourberry. It is made into juices and jellies and the cooked fruit tastes like blackcurrants. The flowers are edible and can be dipped in tempura batter and fried, used to garnish salads and make a drink which is similar to lemonade. The fruit has a mild laxative action.

  Native Americans used the root for stomach upsets and to stimulate the appetite, as well as for a tonic for general debility. Today it is often used for stomach problems, to aid digestion to help with catarrh and to stimulate the functions of the gallbladder and kidneys. In folk medicine an infusion of the root was used as a remedy for syphilis, while an ointment made from it was used for psoriasis and other skin problems. A gargle made from the root was used to relive a sore throat and an infusion was useful as a wash for bloodshot eyes.

  Various coloured dyes are obtained from the plant ranging from yellow and green through to violet and purple. The plants are sometimes used as a low, living hedge, and sometimes the leafy branches are used for Christmas decorations.

  Berberine an alkaloid found in the rhizome of Oregon grape, (also present in Barberries and Goldenseal and so on) is antibacterial and antimicrobial so useful in cases of dysentery, and can help in trachoma (visual impairment which can cause blindness, particularly in the still-developing world) and different forms of conjunctivitis, and has been found to regulate blood sugar levels, making it helpful for people with Type-2 diabetes. It may also help spatial memory impairment and Alzheimer’s patients according to one study by Feiqi Zhu and Caiyan Qan 2006, published in the Journal of Neuroscience.

  In trials on patients an ointment made from the root extracts of the Oregon grape have proved effective in the long term in the treatment of psoriasis, thus providing scientific evidence for traditional use. Gulliver W.P. and Donsky H.J. concluded their study with these words “several investigators in several countries indicate that Mahonia aquifolium is a safe and effective treatment of patients with mild to moderate psoriasis.” (American Journal of Therapeutics, Vol. 12 (5) September to October: pp.398-406)

  Berberine has also been found to boost the immune system, have anti-dandruff and anti-histamine and anti-bacterial effects as well as being anti-fungal anti-ulcer and immuno-modulatory, stimulating the liver and cleansing the blood thus lowering cholesterol levels.

  Another alkaloid found in the rhizome, berbamine, has been found to have potent anti-tumour effects in vitro and in vivo “Berbamine exhibits potent anti-tumour effects on imatinib-resistant CML cells in vitro and in vivo” Yan-Lin Wei et al. Acta Pharmacologia Sina, 2009,Vol. 30pp. 451-457. Berbamine has also been seen to inhibit the growth of leukaemia cells according to the study “The antiproliferation effects of berbamine on K562 resistant cells by inhibiting NF-kappaB pathway” Wei Y. L. et al. Anatomical Record (Hoboken, N.J.:2009)

  Yet again plants have the potential to benefit our health in a very positive way.

THAPSIA GARGANICA OR DRIAS PLANT - WITH GREEK ORIGINS: HISTORY, USES AND HEALTH BENEFITS OF THAPSIA GARGANICA

DRIAS PLANT, FALSE FENNEL, THAPSIA GARGANICA

This plant is native to the Mediterranean area and is called Thapsia because it is said that it was found on the island of Thapsos, although it grows throughout Greece including in Attiki. It is a member of the Apiaceae or Umbelliferae family of plants so is related to carrots, lesser burnet saxifrage, caraway, dill, fennel, sweet Cicely and cow parsley to name but a few of its relatives.

  It grows to around 4 feet tall or 1.2 metres and looks a lot like fennel. It flowers in July and August, bearing fruit in autumn.

  The ancient Greeks called it “the deadly carrot” as any cattle eating it would die, although it is related that indigenous cattle kept away from it - only imported ones were foolhardy enough to eat it. In Algeria it is said to have killed unwary camels within a few days of ingesting it.

  Theophrastus and Dioscorides, the ancient physicians used it and it is related that the Emperor Nero used it mixed with frankincense to heal bruises. It was used as a counter irritant to rheumatic pains, but as it causes burning and a rash along with itching, its use is not recommended. The idea was that the pain caused by its use would stop the feeling of the original pain. In much the same way the Romans are said to have used nettles to restore feeling to numbed limbs on their campaign in Britain in 55 BC.

  The root is emetic and purgative, and resin can be extracted from the root bark. It is poisonous to some animals and best not touched. A preparation of the root was used for lung problems, in folk medicine.

  Scientists have managed to extract phenylpropanoids from the fruit which were “found to be potent cytotoxins” according to a study in Phytochemistry Vol.67 (4) pp 2651-56 by Huizhen Liu et al.

  This research led to other studies and the thapsigargins found in the resin of this plant have been developed as an anti-cancer treatment. Specifically the US Food and Drug Administration (FDA) are conducting phase one trials on a select group of prostate cancer patients and it is hoped that the treatment will prove to be as effective at killing cancer cells in humans as it was in the lab. However it will be some time before the treatment can be deemed safe as trials usually consist of three phases in human subjects.

  Unfortunately it has not yet proved possible to grow this plant in greenhouse conditions, so the species is in danger of becoming extremely rare as the search for thapsigargins continues.

FIELD RESTHARROW: HEALTH BENEFITS AND USES OF FIELD RESTHARROW

FIELD RESTHARROW, LAND WHIN, GROUND FURZE, ONONIS ARVENSIS 

Field Restharrow has a tough weedy stem which could halt the harrows used to till soil, hence its name. The ancient herbalists used this plant to treat bladder and kidney stones and as a diuretic. It is a native of Europe and found in Britain. It flowers in July and August and has pink or purple flowers. It is a member of the Fabaceae (pea family) and the flowers look a little like those of a small sweet pea which is commonly grown in British gardens. It is related to chickpeas, green beans, borlotti beans, lentils, indigo, kudzu or pueraria, senna, alfalfa, carob, broom, lupins, and peanuts to name but a few. It’s more exotic relatives include the Indian coral tree, the ashoka tree, the Monkey Pod tree, dhak, jhand, the pongam tree and the butterfly pea.

  It is endangered and protected in Finland and has been used for culinary and medicinal purposes. The tender young shoots can be pickled or used as a vegetable when cooked, and are said to refresh the breath and disguise the smell of alcohol.

  This plant contains essential oils, flavonoids, glycosides and tannins, with the root being the part employed in traditional systems of medicine in Europe. The root is harvested in September and October, and dried for later use. It is used to stop bleeding from fresh wounds, for headaches, rheumatism skin problems, infections of the urethra and piles. It has been in the official Pharmacopoeias of the former Soviet Union states, the Czech Republic, Serbia and Austria.

  A decoction of the root was used for skin problems as an external wash and an infusion was used incases of delirium.

  Currently research is being carried out into its flavonoid contents 

ARROWLEAF DOCK, KHATTI BUTI: HISTORY AND HEALTH BENEFITS OF AROWLEAF DOCK

ARROWLEAF DOCK, KHATTI BUTI, RUMEX HASTATUS  

Arrowleaf dock is called khatti buti in Urdu which means sour wheat. It is a member of the Polygonaceae or buckwheat family of plants and related to Yellow dock, Common dock, Red dock, sorrel and rhubarb. The Arrowleaf dock is native to the Indian subcontinent and is used both as a vegetable, like spinach, in saag dishes, although the water is changed several times during the cooking process as the older leaves are bitter. The leaf is used in chutneys and pickles as well as to flavour some dishes.

  Arrowleaf dock is also used in traditional medicine systems to treat a number of ailments. One treatment is ½ a kilo of the fresh roots and 250 grams of the bark of an oak tree (Quercus incana) boiled for one or two hours in 4 litres of water until only a litre of liquid is left. The liquid is then filtred and 250 grams of sugar and one kilo of sooji (semolina a wheat product) flour, 250 grams of desi ghee (fat) are added to it and this is cooked for ten to fifteen minutes to make halwa. It is given to people with asthma, coughs or fever.

  This plant can grow up to about 2 feet tall and has pink flowers which bloom throughout March to August. The fruit is also pink and has a one seed. Its leaves are edible and are also used as fodder. It is found in Northern Pakistan, north eastern Afghanistan and south west China, as well as in India.

  In traditional medicine the leaves and young shoots are said to be diuretic, and cooling. Its roots are used in Ayurvedic medicine and other folk medicine systems for rheumatoid arthritis, diarrhoea and dysentery, for wound healing and jaundice among other ailments. The juice of the plant is used to lower and regulate blood pressure and the leaves have laxative properties as well as being used for upset stomachs and bilious attacks, skin diseases, piles and bleeding of the lungs. They are also made into a general tonic for weak animals. The fresh tuber is chewed to relieve a sore throat, and it is believed that this plant is good to treat STDs including the HIV/AIDS.

  Arrowleaf dock has been the subject of several clinical trials and has been found to be effective in the treatment of diarrhoea in lab rats (“Evaluation of Antioxidant activity of extract from roots of Rumex hastatus (Family: Polygonaceae) on experimental animals” Shakuntala et al., Journal of Applied Pharmaceutical Science 1 (6): 2011 pp. 182-5).

  In the Journal of Medicinal Plants Research Vol. 5 (13) pp 2755-2765, Sumaira Sahreen et al July 2011, “Phenolic Compounds and antioxidant activities of Rumex hastatus D. Don. Leaves” found Rumex hastatus leaves “can be used as a good source of potential antioxidant or functional food material due to the presence of sufficient amounts of phenolic such as luteolin and kaempferol.”

  The plant has bioflavonoids and phenolic compounds which need further screening to discover just how beneficial they can be for us and our health. The studies have so far centred on the traditional uses of this plant and have tried to identify the substances which are responsible for its reported actions.

COMMON POLYPODY, FERN WITH TRADITIONAL MEDICINAL USES: HISTORY AND HEALTH BENEFITS OF COMMON POLYPODY

COMMON POLYPODY, POLYPODIUM VULGARE 

Common Polypody is a fern of the Polypodiaceae family and is native to Britain and all other parts of Europe through to the Mediterranean region, temperate Asia and the eastern parts of North America. It is found in shady, moist places and on old walls and rocks. It grows from a creeping rhizome which has been most frequently used in traditional herbal medicine in Europe.

  It is a British native fern along with bracken, moonwort, hart’s tongue, adder’s tongue and spleenwort. It was a familiar sight when I was growing up in south Wales. The ancients believed that it grew on the roots of the European oak, which was the Druid’s sacred tree imbued with potent power, as was mistletoe which grew on it and also common polypody. Now we call another fern the Oak Fern, Gymnocarpium dryopteris. However at one time this was known as the Oak Fern, Polypody of the oak, and also Wall fern, and Brake root among other names. The genus name, Polypodium means many footed in Greek.

  The rhizome is best when harvested in autumn, in October or November and used fresh or dried. The European Medicines Agency published a report on its traditional use in 2008 and as it has been safely used for more than thirty years as a mild laxative it is considered to be safe, although not recommended for use by children under twelve years old or during pregnancy or breastfeeding. It has been used for a number of purposes including for jaundice and hepatitis, indigestion and stomach upsets, to promote appetite, for respiratory problems, as a diaphoretic, diuretic and expectorant, although it should be remembered that it does have mild laxative problems. The EMA recommend that it should not be taken for longer than a week. It may cause a rash so is not recommended for external use and it can sometimes cause a rash which is not harmful when taken internally. (Assessment Report on Polypody vulgare, L., Rhizoma EMA, London 6^th November, 2008)

spores

  Traditionally the root has been used as a poultice for rheumatic swellings, for hives, sore throats and stomach upsets. In the past a tisane or infusion was used to drive away melancholy and for scurvy (vitamin C deficiency); when it was combined with the common mallow or the marsh mallow it was used for hardness of the spleen and pains in the side (stitches). It has also been used over a period of time for skin diseases.

  The infusion was made with ½ ounce of the crushed roots to one pint of boiling water, left to steep for 10 minutes before straining and using in teacupfuls throughout the day as an expectorant, laxative and to promote appetite. Honey was used to sweeten it if necessary.

  The root has a sweet taste although this is quickly cloying and has been used as a liquorice adulterant. The distilled water of the root was used for fevers as a diaphoretic, to promote sweating.

  The fern fronds are mucilaginous and the mature ones, collected in autumn were boiled with coarse sugar or gur (jaggery) and the resultant liquid was given to children with whooping-cough.

  John Gerard the English herbalsit who translated the works of ancient herbalists has this to say of this fern:-

“Johannes Mesues reckoneth up Polypodie among those things that do especially dry and make thin: peradventure he had respect to a certain kind of arthritis or ache in the joints: in which not one part but many together most commonly are touched: for which it is very much commended by the Brabanders and other inhabitants about the river Rhene and the Maze. Furthermore Dioscorides saith that the root of Polypodie is very good for members out of joint and for chaps between the fingers.”

polypody spores

  A century later, Nicholas Culpeper has this to say in his “Complete Herball”:-“Government and virtues. It is under Jupiter in Leo. With laxatives it gently carries off the contents of the bowels without irritation. By itself it is a very mild and useful purge; but being very slow, it is generally mixed by infusion or decoction with other purging ingredients, or in broths with beets, parsley, ammow, cummin, ginger, fennel and annise. With mucilaginous herbs, as white beet and mallow, it is excellent in cholics. The powder taken to half a drachm daily, and fasting three hours after, is good for the spleen, jaundice, and dropsy, for it is as fine an alternative as can be procured, and will penetrate farther than most other things yet known. Some use its distilled water in a cough, asthma, diseases of the lungs, pleurisies, obstructions of the mysentery, and in whatever cases acrimony is to be subdued. The best form to take it for any complaint of the intestines, is as follows: to an ounce of fresh polypody root bruised, add an ounce and a half of the fresh roots of white beets, and a handful of wild mallow; pour upon these a pint and a quarter of water, boiling hot, and let it stand till next day, then strain it off.” (mesentery is a double fold on the peritoneum wall.)

GIANT PUFFBALL - BIGGEST EDIBLE FUNGUS: HISTORY, USES AND HEALTH BENEFITS OF THE GIANT PUFFBALL

GIANT PUFFBALL, CALVATIA GIGANTEA

The giant puffball mushroom can be found in Europe including Britain, and North America. If you see a mushroom the size of a football in a field or on the edges of woodland then it is probably the giant puffball which was once named Langermannia gigantea. Its correct Latin name is now Calvatia gigantea. They can grow to enormous sizes, with the largest British specimen being 64 inches (162 centimetres) in circumference and a reported on from the US was 1.5 metres across and weighed in at an amazing 20 kilos. However these are giants of the giant puffball world; a 4 kilo puffball is more usual.

  The young immature puffball is edible and has a rich, earthy, nutty taste, although some believe it to be bland, only taking on the flavours of the foodstuff it is cooked with. They are delicious fried in butter and good in an omelette. Some say that they can be used instead of tofu or aubergines, but they are good chopped in any recipe that calls for mushrooms. You should only eat giant puffballs which have no gills and have not formed spores. When this happens they turn a pale yellow colour and as they mature they become yellow-brown. They have to have solid white flesh in their interior for them to be edible. In the UK you can sometimes find them in specialty mushroom shops.

  When they have formed spores and are ready to ejaculate them, a single drop of rain will trigger the spores’ release. Children love kicking them to release the powdery spores, and as they are inedible at this time it isn’t a waste of a mushroom.

  Native Americans used the spores for wound healing as they help blood to coagulate and it is believed that they have antiseptic properties.

  Back in the 1960s a substance named calvacin was isolated from giant puffballs and proved to have anti-tumour properties in vitro. When experiments on animals became increasingly used this substance was tested on lab rats but unfortunately. Although it did kill the cancerous cells and the tumour it had bad side effects and caused anorexia, acute liver failure, muscle inflammation and bleeding from the lungs. Some rats died within two days of being subjects of the experiment.

  However in 2008 new research was conducted into the substances which can be found in these mushrooms and three were found to be present which had not been reported in mushrooms previously: Methyl anthranilate, Methyl N N-dimethylanthranilate and Methyl N-methylanthranilate. (“Volatile Constituents of the Giant Puffball Calvatia gigantea” by John C. Leffingwell and E. D. Alford in Leffingwell Reports Vol. 4 March 2011.)

  Although these mushrooms can be found in most of Europe they are a cause for conservation concern in Norway and are becoming rare in Lithuania and are protected in Poland, so you can’t forage for them there.

  In Britain they have been used as kindling and placed under beehives to make bees sleepy so that the beekeepers can get into the hives. At one time it was thought that they had narcotic effects on bees but this has proved not to be the case.

  Apart from eating them, our ancestors used them for tinder as this piece of information from the 16^th century British herbalist, John Gerard, shows.

  “In divers parts of England, where people dwell farre from neighbours, they carry them kindled with fire, which lasteth long.”

  They have similar nutrition qualities as other mushrooms including morels, chanterelles and the oyster mushrooms.
