TEAK TREE IS NOT ONLY USED FOR ITS WOOD: HEALTH BENEFITS AND USES OF TEAK TREES

TEAK TREE, TECTONA GRANDIS 

The teak tree is renowned for its durable wood which can be used for almost any purpose, including in the construction industry, for furniture, flooring, ships’ decks, and because it is resistant to the wood-boring mollusc, the shipworm, it is used for piers and jetties too. It has quinones in its sawdust which are resistant to fungi making it ideal for many purposes in tropical conditions.

  It has its origins in south and south-east Asia, but is now cultivated in many parts of the world for its timber. It is a member of the mint or Lamiaceae family and so is related to the Chaste Tree and Fragrant Premna, as well as herbs, marjoram, basil, Holy basil, oregano, savory, thyme, lavender, lemon balm, bugle, motherwort, self-heal, wall germander, cat nip, ground ivy, Jupiter’s sage and hyssop and a whole host of other plants. As one of the verbenas (some botanists classify this as a member of the Verbenaceae family) it is allied with vervain (Verbena officinalis) and lemon verbena.

  Teak trees can grow to heights of forty metres and have white through to cream flowers which are followed by pale yellow fruit which are about 1 or 2 centimetres in diameter and covered with star-shaped hairs.

  It is cultivated now throughout the tropics and has its uses in traditional systems of medicine in countries where it grows. Virtually every part of the teak tree has medicinal uses, and medical science has shown that the leaves have antibacterial, anti-ulcer and antifungal properties. In Ayurdeva the wood is considered a laxative, a sedative for the uterus, good for piles, dysentery and leucoderma. In folk medicine the roots are used for urinary tract problems, the flowers for bronchitis, nausea and urinary tract problems too. The bark has been used to treat diabetes, and an extract of the bark has been found to have insulin resistance in mice.

  In other parts of Asia a decoction of the fresh or dried leaves is used for menstrual problems and haemorrhages, as well as a gargle for sore throats. A plaster made from the powdered wood is applied to headaches which cause nausea, and too disperse swellings which are caused by inflammation, perhaps caused by rheumatism for example. The powdered wood is used internally to get rid of intestinal parasites, and, made into a paste with water, it is used on swollen eyelids and also for acute dermatitis and other skin irritation. In India the charred wood is soaked in poppy juice and made into a paste for swollen eyelids. Flowers and seeds have diuretic properties while the oil from the fruit seeds is used to stimulate hair growth and soothe irritated skin.

  Dyes are produced from the root bark and young leaves and this is used for paper products, matting and cloth. The dyes may be yellow-brown or red-brown. Dye from the leaves alone is used for dying cloth especially wool and cotton. In Java, Indonesia, the sawdust is burnt as incense.

  The leaves are edible and can be filled with jackfruit and other ingredients and steamed, and are combined with jackfruit in other ways to make desserts in southern India and in parts of Indonesia too.

  Research is ongoing to attempt to prove that there are scientific bases for the tree’s use in traditional systems of medicine.

ACONITE, POISONOUS PLANT: HISTORY OF USES OF ACONITE NAPELLUS

ACONITE, MONKSHOOD, WOLFSBANE, ACONITUM NAPELLUS 

Aconite has been used for pain relief and was in the British Pharmacopeias, but only that grown in Britain, however there is no scientific evidence to support its use as a cancer treatment, whether as a cure or for preventative purposes. Neither is there evidence for its other purported uses. Aconite is extremely poisonous as is datura or thornapple and aak. Aconitum napellus is an attractive flowering plant whose leaves, stems and roots were especially valued in medicine until the mid 1900s. However it has fallen into disuse because it is so poisonous.

  It has been used in traditional Asian medicine in China, Japan and in Ayurvedic medicine in the Indian sub-continent for centuries, but the poisonous principle is removed by processing the plant and it is used only in miniscule dosages. It is used as a pain-reliever in inflammatory problems such as gout, migraines, rheumatism and sciatica, but is used to cure the symptoms and not the disease itself.

  It is a member of the buttercup of Ranunculaceae family and as such is a relative of the Lesser Celandine, marsh marigolds, black cohosh, wood anemones and goldenseal. It grew in South Wales when I was growing up and looked to me like a delphinium (larkspur). It seems to like to grow on rocky, craggy places and aconite comes from the Greek akonos which means stone while napellus refers to the root shape which was thought to resemble a small turnip.

   It gets the name monkshood because the petals are thought to resemble a monk’s cowl.

  Aconite causes arrhythmia, heart failure and death and was Medea’s poison of choice in her potions, one of which was destined for Theseus, who did not drink it. The Greek myth says that aconite grew from the slobber of the three-headed dog, Cerberus who guarded the gate of Tartarus. Because of the association with this hell-hound it has been called Dog’s bane. Athena used its poison to turn Arachne into a spider for her impiety, and it was much feared by the ancient Romans. The Roman Emperor Claudius I was poisoned with it by his physician and the Emperor Trajan forbade its cultivation under pain of death. It was referred to as Hecate’s herb (Hecateis herba) in Mediaeval times and it was believed to have been an ingredient along with Belladonna of witches’ flying ointment.

  Aconite can be absorbed through the skin, whether broken or not so should not be used externally or internally.

  Pliny wrote that aconite could kill a mouse that was some distance away, and for this reason it was called mousebane by some. The name wolfsbane comes from the belief that it could turn people into werewolves or perhaps cure them of being wolf men. Its poison was also used to tip arrows to kill wolves.

  John Gerard, the English herbalist writing in the 16^th century wrote that it was “so forcible that the herb only thrown before the scorpion or any other venomous beast, causeth it to be without force or the strength to hurt” until the plant was removed.

  In 1603, Ben Jonson the English playwright has this to say about aconite in his play “Sejanus, his fall”

“I have heard that Aconite

Being timely taken hath a healing might

Against the scorpion’s stroke.”

Shakespeare in his play Henry IV part 2 Act 4 scene 4 mentions it in this way:-

“A hoop of gold to bind thy brothers in,

That the united vessel of their blood,

Mingled with venom of suggestion-

As perforce, the age will pour it in-

Shall never leak, though it do work as strong

As aconitum or rash gunpowder.”

  Much late in his poem Flowers, Thomas Hood (1799-1845) an English poet, mentions it in this way: -

 “The wolfsbane I should dread;

   Nor will I dreary rosemarye,

   That always mourns the dead;

   But I will woo the dainty rose,

   With her cheeks of tender red.”

It is best not to touch this plant especially if you have broken skin, and don’t be tempted to make your own poison with it –it has been too well documented in literature as a poison (Brother Cadfael books, Harry Potter and others).

FRAGRANT PREMNA TREE, WITH LOTS OF POTENTIAL BENEFITS: HEALTH BENEFITS AND USES OF THE FRAGRANT PREMNA TREE

 FRAGRANT PREMNA, ALAGAW, PREMNA ODORATA 

The Fragrant Premna is a small tree or shrub which can flower at 3 or 4 metres high, but which can grow to heights of 8 metres. It is a member of the mint or Lamiaceae family, or the Verbenaceae family. This being so it is related to marjoram, basil, Holy basil, oregano, savory, thyme, lavender, lemon balm, bugle, motherwort, self-heal, wall germander, cat nip, the Chaste tree, ground ivy, Jupiter’s sage and hyssop and a whole host of other plants. As one of the verbenas it is allied with vervain (Verbena officinalis) and lemon verbena.

  This tree or shrub is native to the Philippines, where it is used for a number of ailments in folk medicine. It has aromatic leaves which are fragrant when crushed, thus giving rise to the Latin name odorata, meaning fragrant. Its flowers, which are a green-white, grow in clusters as do those of the elder tree and its dark purple berries are also reminiscent of those of the elder.

  A decoction of the leaves mixed with sugar or honey and lemon juice is drunk for coughs, while a decoction of the fresh leaves is used for vaginal irritation. The fresh leaves, applied over the bladder area promote urination it is believed. An infusion of these is given for flatulence, and when children have tympanites (a swollen abdomen due to gas or air in the abdomen or the peritoneal cavities) the leaves are mixed with coconut or sesame oil and this lotion is applied to the swollen area. A decoction of the leaves and flowers is given to remedy fever, stomach pains and dysentery, while a decoction of the roots, leaves, flowers and fruit is given for chest complaints such as coughs and bronchitis.

  When the leaves are boiled in water, the liquid is used to bathe babies, and the boiled leaves are also applied externally for beriberi which is a deficiency of thiamin (vitamin B1). A decoction of the young shoots kills parasites too, and it is believed that if you chew the root and then swallow the resulting saliva, this is good for heart problems.

  Clinical trials have shown that extracts from the plant have antimicrobial and anti-inflammatory properties (Lunesa C.Pinzon et al. “Isolation and characterization of antimicrobial, anti-inflammatory and chemopreventive flavones of Premna odorata Blanco” Journal of Medicinal Plants Research, Vol.5 (13) pp2729-2735, 4^th July 2011). It has potential in cancer treatment too but the study concludes with the sentiment that more research is needed to ascertain how the tree and its extracts can be used for the benefit of patients.

WALL OR COMMON GERMANDER, NO LONGER RECOMMENDED FOR INTERNAL USE: HISTORY OF USES OF WALL GERMANDER

WALL OR COMMON GERMANDER, TEUCRIUM CHAMAEDRYS 

Wall Germander is native to Europe and the Mediterranean region. It grows to about a foot high and wide, and is an evergreen shrub, naturalized in Britain because it was widely cultivated for medicinal purposes. It is a member of the mint family, (Labiatae or Lamiaceae family) and as such is related to marjoram, basil, Holy basil, oregano, savory, thyme, lavender, lemon balm, bugle, motherwort, self-heal, cat nip, the chaste tree, ground ivy, Jupiter’s sage and hyssop, among many other plants.

  It was used in Elizabethan and Jacobean knot gardens and planted as an ornamental. Bees love this plant and will ignore others and go to it in a herb garden. It usually has pink through to pale purple flowers, although these can be white, but this is rare.

  It has been found to cause hepatitis and jaundice so its use is not recommended. However in the past it was used as a diuretic for gout and as a diaphoretic (promoter of sweat in fevers); it was also used in tonic wines and as a stimulant, with the leaves generally being used, although the whole herb can be collected in July when the flowers are still blooming, and dried for later use.

  Germander is believed to be a corruption of chamaedrys, which means ground oak- so named because the leaves look like those of an oak tree. (Chamai means ground and drys oak in Greek.) The genus name, Teucrium is thought to refer to King Teucer of Troy, who was famed as an archer. One of the uses of the leaves is in an infusion to heal wounds as these have astringent qualities. This infusion can also be used as a mouth wash for bleeding gums, and was once used as an antidote to snake bites.

  The leaves have been used to flavour vermouths, and bitters, as well as liqueurs, and it has also been used in much the same ways medicinally as the bitter herb, horehound.

  It is said that King Charles V the Holy Roman Emperor was cured of gout after taking a treatment involving germander for 60 days. Today the plant is mixed with wild celery (Apium graveolens) and meadowsweet and Guaiacum officinale to treat rheumatoid arthritis.

  In one trial it exhibited analgesic (pain-relieving) and anti-inflammatory properties (“Analgesic and Anti-inflammatory Activity of Teucrium chamaedrys Leaves Aqueous Extract in Male Rats” Ali Pourmatabbed et al. Iranian Journal of Basic Medical Sciences Vol.13 (3) pp119-125, summer 2010.)

  Culpeper, writing in the 17^th century has this to say of the plant:-

  “Government and virtues. It is a most prevalent herb of Mercury, and strengthens the brain and apprehension exceedingly when weak, and relieves them when drooping. This taken with honey (saith Dioscorides) is a remedy for coughs, hardness of the spleen and difficulty of urine, and helps those that are fallen into a dropsy, especially at the beginning of the disease, a decoction being made thereof when it is green, and drank. It also brings down women's courses, and expels the dead child. It is most effectual against the poison of all serpents, being drank in wine, and the bruised herb outwardly applied; used with honey, it cleanses old and foul ulcers; and made into an oil, and the eyes anointed therewith, takes away the dimness and moistness. It is likewise good for the pains in the sides and cramps. The decoction thereof taken for four days together, drives away and cures both tertain and quartan agues. It is also good against all diseases of the brain, as continual head-ache, falling-sickness, melancholy, drowsiness and dullness of the spirits, convulsions and palsies. A dram of the seed taken in powder purges by urine, and is good against the yellow jaundice. The juice of the leaves dropped into the ears kills the worms in them. The tops thereof, when they are in flowers, steeped twenty-four hours in a drought of white wine, and drank, kills the worms in the belly.”

WOOD ANEMONE, FLEETING STAR OF THE WOODS: HEALTH BENEFITS AND USES OF WOOD ANEMONES

WOOD ANEMONES, ANEMONE NEMOROSA

Wood anemones as you might expect are found in woods and shady places. Like Tickle Me and wood sorrel, they close their flowers at the hint of rain and close at night, so that they are protected from dew. They are sometimes referred to as wood crowfoot as they are members of the buttercup or Ranunculaceae family of plants. As such they are related to the Lesser Celandine, marsh marigolds, black cohosh, and goldenseal.

  The whole plant contains protoanemonin which can cause skin and gastrointestinal irritation, although this turns to harmless anemonin when it is heated or dried. The plant is indigenous to most of Europe and western Asia. It can grow to around a foot in height but is usually around 8 inches high.

  It is called windflower as ‘anemone’ comes from the Greek anemos which means wind, so Pliny writes about it as the windflower, believing that the flowers only opened when the March winds blew.

  Its leaves have been used as a counter-irritant to rheumatic pains as stinking hellebore, another relative and of course stinging nettles. All above ground parts of the wood anemone have been used in previous times in folk medicine in Europe, for gout, headaches, some fevers and menstrual problems.

  It has something of a sinister reputation historically, although it is not known why this is unless it caused death when people ate the root or ingested other parts of the raw plant. The ancient Egyptians used it as a symbol of sickness, and the Chinese called it the “Flower of Death.” The Romans, on the other hand, would pick it to ward off fever.

  Culpeper says that the root may be chewed, but the fresh root will cause burning and mouth ulcers. This is what he has to write about it: -

“Government and virtues. It is under the dominion of Mars, being supposed to be a kind of crow-foot. The leaves provoke the terms mightily, being boiled and the decoction drunk. The body being bathed with the decoction of them cures the leprosy. The leaves being stamped, and the juice snuffed up the nose, purges the head greatly: so doth the root being chewed in the mouth, for it causeth much spitting; and brings away many watery and phlegmatic humours, and is therefore excellent for the lethargy. And when all is done, let physicians say what they please, all the pills in the dispensatory purge not the head like to hot things held in the mouth: being made into an ointment, and the eye-lids anointed therewith, it helps inflammations of the eyes, whereby it is palpable that every stronger draweth its weaker light; the same ointment is exceeding good to cleanse malignant and corroding ulcers.”

  It is wise to remember that Culpeper was writing his Complete Herball in the 17^th century, and the wood anemone is now known to have harmful side effects; it is best left in its habitat - or you might upset the fairies, who are said to sleep in the centre of the flowers at night when they close the curtains tightly for protection from the elements.

The wood anemone has been the subject of many poems, this sonnet by John Clare (1793 – 1864)

“The wood anemone through dead oak leaves
And in the thickest woods now blooms anew,
And where the green briar and the bramble weaves

Thick clumps o'green, anemones thicker grew,
And weeping flowers in thousands pearled in dew
People the woods and brakes, hid hollows there,
White, yellow and purple-hued the wide wood through.
What pretty drooping weeping flowers they are:
The clipt-frilled leaves, the slender stalk they bear
On which the drooping flower hangs weeping dew,
How beautiful through April time and May
The woods look, filled with wild anemone;
And every little spinney now looks gay
With flowers mid brushwood and the huge oak tree.”

and this poem by Emily Dickinson:

“Summer for thee, grant I may be

When Summer days are flown!

Thy music still, when Whipporwill

And Oriole -- are done!

For thee to bloom, I'll skip the tomb

And row my blossoms o'er!

Pray gather me --

Anemone --

Thy flower -- forevermore!”

  These poems are only two examples of the wood anemone’s appearances in poetry.

  

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.
