INDIAN CORAL TREE: HISTORY, USES AND HEALTH BENEFITS OF THE INDIAN CORAL TREE

INDIAN CORAL TREE, TIGER’S CLAW, ERYTHRINA VARIEGATA 

The Indian coral tree is as its name suggests native to the Indian subcontinent, and its range extends throughout South-east Asia to Malaysia. It was introduced in ancient times to the Pacific islands and to parts of Africa. The Indian coral tree is a member of the Leguminoseae or Fabaceae family of plants making it a relative of dhak, the pongam tree, ashoka (Saraca indica),the monkey pod tree, jhand, lentils, indigo, the butterfly pea, chickpeas, soya beans and lupins to name but a few.

  The tree is useful as a nitrogen fixer and helps poor soil increase its fertility. It is panted as an ornamental and a shade tree, and used for this last purpose in coffee and cacao plantations. It is also used as a trellis for vines and climbing plants and is used to support the betel nut (paan) vine, black pepper plants, as well as vanilla and yams.

  The bark of this tree is paper-thin and can be yellow through to brown, and the seed pods contain between five and twelve seeds. The tree can grow to around sixty feet although they rarely grow to heights of more than fifty feet (fifteen metres). Some people in Bangladesh use the seeds, a kidney-shaped bean that looks rather like a red kidney bean, as food, but mostly they are not eaten. The seeds contain oil and it has been suggested that this could be a source of biofuel in the future. The pods grow to between six inches and a foot. The trees have thorns on their branches, but nonetheless the pods are used for fodder. However this means that they make useful living fences to demarcate boundaries and deter animals.

  The bark and leaves of this tree are mainly the parts used in Ayurvedic medicine in the Indian subcontinent, with the juice from the leaves being put into ears to stop earache. The paste made from the tree parts is used for rheumatism and joint pains, applied to the affected areas, and it is also used for wounds as it has antiseptic properties, and for inflammation, including for eye problems. A powder is made to aid digestion, as an aphrodisiac and for erectile dysfunctions. It is also used to get rid of intestinal worms, for blood purification, to regulate menstruation, for infections of the urinary tract such as cystitis, obesity, fevers and externally for skin problems.

  It is believed to support the liver and nerves functions and is anti-inflammatory, analgesic (pain-relieving), and to dilate the blood vessels. An infusion of the bark and leaves is used for coughs as an expectorant. A preparation is also used for insomnia, to promote lactation in breast-feeding mothers, for lower back pain relief and knee pain as well as for rheumatism.

  Clinical studies have found that the isoflavonoids present in this coral tree can help protect bone mass in mice and have anti-osteoporotic effects (2007, Zhang Y. et al. Journal of Ethnopharmacology, Vol.109 (1) pp 165-9). However these actions have not been tested on humans.

  In a 2002 study conducted by Tanaka H. et al. the isoflavonoids were found to have antibacterial properties. More studies are underway to discover whether the traditional medicinal uses of this tree have scientific bases.

  

MOTHERWORT - HERB OF ANCIENT USAGE: HEALTH BENEFITS AND USES OF MOTHERWORT

MOTHERWORT, LION’S EAR, LEONARUS CARDIACA 

Motherwort is a native of mainland Europe, but has become naturalized in the British Isles, as it was commonly grown in gardens for its medicinal properties. It is the only one of the Leonarus genus which grows wild now in the UK. When not in flower it can be mistaken for mugwort.

  It is a member of the Labiatae or Lamiaceae family of plants and as such is a relative of mint, marjoram, basil and Holy basil, oregano, savory, thyme, lavender, lemon balm, bugle and hyssop among many others. It flowers between July and September and is best harvested and dried for later use in August.

  Motherwort has been used in the past to flavour lentil and dried pea soups and a tisane may also be made from its flowering tops. However as Culpeper mentions, it tastes bitter and is best used in a conserve with honey or sugar to sweeten it.

  If you go near the plant be careful as it has sharp toothed edges which can cause injury to the mouths of grazing animals and hands. It has been known to cause dermatitis, and its essential oil can cause photosensitivity. It should be avoided during pregnancy. As its name suggests it has been mainly used as a woman’s herb for labour pains and childbirth, to promote menstruation and for nervous and hysterical disorders (it has a sedative action). Like borage, which tastes much better, it was used to gladden the heart and spirits, and was useful as a nervine and cardiac tonic. It was thought that it could keep evil spirits away, perhaps meaning that a person would not be overcome by melancholy.

  Culpeper writing in the 17^th century has this to say of its medicinal properties: -

“Government and virtues. Venus owns the herb, and it is under Leo. There is no better herb to take melancholy vapours from the heart, to strengthen it, and make a merry, cheerful, blithe soul than this herb. It may be kept in a syrup or conserve; therefore the Latins called it Cardiaca. Besides, it makes women joyful mothers of children, and settles their wombs as they should be, therefore we call it Motherwort. It is held to be of much use for the trembling of the heart, and faintings and swoonings; from whence it took the name Cardiaca. The powder thereof, to the quantity of a spoonful, drank in wine, is a wonderful help to women in their sore travail, as also for the suffocating or risings of the mother, and for these effects, it is likely it took the name of Motherwort with us. It also provokes urine and women's courses, cleanses the chest of cold phlegm, oppressing it, kills worms in the belly. It is of good use to warm and dry up the cold humours, to digest and disperse them that are settled in the veins, joints, and sinews of the body, and to help cramps and convulsions.”

  In more modern times it has found a use in some thyroid treatments, and heart palpitations. The infusion can be made with one ounce of the fresh tops to one pint of boiling water left to steep before draining and drinking in small cupfuls three times a day. The alcohol extract of this plant is said to have an action superior to that of valerian.

  It can be used as a diaphoretic to promote sweating, and in recovery from fevers. The tisane or infusion can help in cases of neuralgia and it was generally regarded as an excellent general tonic. However it is not much used these days.

EUROPEAN PAEONY, LEGEND, HISTORY, USES AND HEALTH BENEFITS OF THE PAEONY

EUROPEAN OR COMMON PAEONY, PAEONIA OFFICINALIS 

The European paeony is native to mainland Europe, with its range extending from France, through to Albania. There is another variety of paeony which is native to Greece.

In Britain there used to be wild paeonies on the island of Steep Holme in the river Severn, close to the Bristol Channel, (interestingly there were none on the neighbouring island of Flat Holme, so they were probably introduced and became naturalized.) but these do not seem to have survived. This wild paeony is single-petalled and a deep pink, and was valued in the Middle Ages for it seeds rather than its flowers, so in paintings on altars in churches from this time, the paeony is portrayed with a ripe seed capsule.

  I grew up with paeonies in the garden and the plants we had were very old, and I know now that these bushy plants are renowned for their longevity. I loved their smell and colour and often tried to capture their beauty in drawings and paintings without much success. You can dry the petals and use them in tisanes which are good for colds, and the flowers can also be cooked and eaten as a vegetable I’m told (as can flowers from the kachnar tree Bauhinia variegata).

  The name paeony is said to have come from the name (Paeos) of a student of the Greek physician Asclepius. This acolyte of the great physician earned his jealous wrath when he cured the god of Hades of his wounds which he had received during the Trojan Wars. He was turned into the plant that now bears his name to escape death at the hands of Asclepius according to one myth. Another is that he cured the gods of Olympus of their wounds with the juice from this plant – although I suppose it would have been the juice from the indigenous Greek paeony which he used, not the European one.

  This wild paeony was cultivated by Benedictine monks in their monastery gardens in the Middle Ages and from these it became common in cottage gardens. John Gerard, writing in the 16^th century, recommends paeony seeds as a way to prevent nightmare and melancholic dreams. The flowers and seeds especially were thought to have the ability to ward off evil, and the seeds were threaded sometimes to make necklaces for this purpose.

  The paeony has a few superstitions surrounding it and it was thought unlucky to dig up the roots, which was unfortunate as these have medicinal properties as well as the seeds.

 Pliny the Elder, probably relating a tale told by Theophrastus (c.327-287BC), relates this piece of cautionary information: you should dig the paeony root up only at night because if you are seen doing so by the woodpecker it will peck out your eyes.

  The seeds can be dry roasted and used as a condiment if ground when still warm and added to soups and stews as a spice. The root should be harvested in autumn and dried thoroughly in the sun for later use. It has antispasmodic properties and has been made into suppositories for intestinal and anal spasms. During the Middle Ages the root was dried, powdered and used to treat epilepsy and lunacy as well as to promote menstruation. No preparations of paeony should be taken during pregnancy.

  The tisane or infusion made from the dried crushed petals can be used as a lotion for varicose veins and piles and taken internally is good for coughs. One ounce of crushed petals to one pint of boiling water drunk in small cupfuls can be taken three times a day.

  In Christian symbolism, again in the Middle Ages, paeonies represented feminine beauty, wealth and healing powers. In medicine during those times the seeds were used in medicines to disperse blockages in the internal organs, especially to get rid of bladder stones, as they have diuretic qualities, for jaundice, stomach pains, diarrhoea and labour pains.

  This paeony is no longer used in medicine except in some homeopathic remedies.

POKEWEED, "GOURMET" FOOD: HISTORY, USES AND HEALTH BENEFITS OF POKEWEED

POKEWEED, PHYTOLACCA AMERICANA 

Pokeweed is a member of the Phytolaccaceae family, also called by a number of other names such as Poke root and American nightshade. Like Belladonna it is poisonous and if handling it, especially if you have scratches on your hands, wear gloves. It is native to North and Central America but has naturalized in parts of Britain where it is a garden escapee. It is a relative of the Guinea hen weed.

  It can grow to heights of six feet (around 2 metres) and may have a spread of around 5 feet. It flowers in August and September, and these are followed by fruit, which looks tasty but is poisonous to children and animals. Only birds seem immune to it and scatter the seeds through their droppings.

  Despite its poisonous nature the young shoots and leaves are considered “gourmet” food as is asparagus, and are the basis of “poke sallet” in southern US states. It is said to taste a little like asparagus or spinach. You should only take the shoots in spring from plants that are less than 8 inches tall, as the toxicity increases and the taste becomes bitter later in the year and in taller specimens. If you do cook these spring greens you will need to boil them thoroughly in two changes of water so that the toxins are leached out. Apparently they are available in cans too.

   The leaves are rich in vitamins A and C and some of the B-complex ones, including thiamin (B1), riboflavin (B2) and niacin (B3). They also contain the minerals calcium, phosphorous and iron.

  The juice from the berries (which have the least amount of poison than the rest of the plant) has been used by Native Americans to dye feathers and arrow shafts and they produce an attractive red dye which is temporary and can be washed out. A red ink can also be obtained from the berries, but again this, like the dye is not permanent.

 The Native Americans used the extremely poisonous roots externally in poultices for sprains and swellings, and in preparations for skin troubles and rheumatism. These are violently emetic and purgative and may be fatal, causing paralysis of the respiratory organs. However were also employed by Native Americans as cancer and syphilis remedies and as a heart stimulant in the same way as digitalis from the foxglove is used.

  In traditional medicine pokeweed has been used for breast cancer, mastitis, mumps, sore throats, swollen glands, bronchitis, constipation, fungal infections, inflammation of the joints, and externally for skin problems, piles and itching.

  Clinical studies have discovered a protein called pokeweed antiviral protein (PAP) which has had anti-tumour effects on mice and this has also shown some activity against the HIV virus. However as yet there are no indications that this is effective in humans. The plant’s extracts have proved to be effective against water snails which carry bacteria and studies into this activity are ongoing as are the other studies mentioned.

  The roots infusion was used for swellings and sprains and harvested in the autumn for these purposes and dried for later use. These have narcotic, expectorant, anti-inflammatory, hypnotic and purgative properties. The fruit with its milder action than the root has been used for cancer, tumours and sore breasts. The leaves also have emetic and expectorant properties.

  The poisonous substances are saponins-like and the roots can be chopped and boiled to produce a soap substitute, as can other plants such as soapwort and reetha (soap nut). This plant should not be used for home remedies but may be safe in homeopathic remedies for muscular tissues, throat, breast and painful joint.

AFRICAN SHEA TREE - TREE OF LIFE: HISTORY, HEALTH BENEFITS AND USES OF THE SHEA TREE

AFRICAN SHEA TREE, KARITE, VITELLARIA PARADOXA 

The Shea tree is native to the African continent and is propagated by fruit bats. It was formerly called Butyrospermum parkii or Butyrospermum paradoxa although it is now known as Vitellaria paradoxa. The name Butyrospermum means butter seed which is a good description as the seeds is the producer of shea butter which is used in cosmetics. The parkii part of its former name was in honour of the Scot, Mungo Parks, the explorer who set out to find the source of the Niger River and who was the first European to describe this tree in the 1790s in his book “Life and Travels of Mungo Park in Central Africa.”

  The tree has spreading branches resembling an oak tree and the fruit looks a little like chikoo or sapodilla to which it is related as both trees are members of the Sapotaceae family. The tree can grow to heights of between 25 and 75 feet (7.6 metres to 22.7m.) Trees begin to produce fruit when they are between 10 and 15 years old, and reach peak production when they are 20 to 30 years old, although they can continue producing fruit the size of large plums, for two hundred years.

  It is the kernels which are enclosed by the pulpy flesh which produce the shea oil or butter which is called ‘women’s gold” in the countries where it is grown as money from producing the oil and butter goes to the women who process the kernel painstakingly. Nowadays there are initiatives helping women to market their produce to European and Asian countries where it is valued not only for its inclusion in cosmetics but also as a partial substitute for cocoa butter and used in chocolate making.

  The tree, like the baobab tree is known as the tree of life, karite, as it provides food and medicine for the people who live in the regions where it grows wild.  The fruit contains four times as much vitamin C as oranges, and the oil has vitamins A and E in it. The kernel is rich in oleic, arachidic, palmitic, stearic and linoleic fatty acids.

  All parts of the tree are used in medicine, for skin diseases including leprosy, dermatitis and eczema, to protect from sunburn, as the oil can counter harmful ultra-violet rays from the sun, and also soothe sunburn. It is also used for wounds and to massage into stiff joints, as well as to treat sore and injuries of animals. The roots are used for cleaning the teeth and oral health in the same way as the walnut tree bark is used in Pakistan, and the dried ground roots are used to treat jaundice, diarrhoea, dysentery and other stomach upsets. The bark of the tree is used to treat leprosy and stomach upsets too, and for eye problems and to get rid of parasites which attack the bare feet. The nut husks are used for fertilizer and fuel, and the inferior oil which may be produced is used for lighting and to waterproof beehives. The oil and butter can also be used in cooking, while the wood can resist the ravages of termites and is used in furniture making and construction.

  The oil and/or butter is also used in religious ceremonies or spiritual purification and to anoint the dead. The rubbery sap or latex from the tree is used as glue and for children’s balls and as chewing gum, while the black residue from the butter-making process is used to fill cracks and to waterproof buildings.

  The European Union’s 2003 directive allows a percentage of shea butter to be substituted for cocoa butter in the chocolate industry and even as early as the 1940s shea butter was used in the West to make margarine. The tree is protected but is sometimes felled illegally because of the need to survive, whether that is to clear land to plant crops or to use the wood for fuel to cook food.

  An Australian study published in the Journal of Phytotherapy Research in 2010 concluded that a supplement containing shea butter could help to relieve joint inflammation. Other research indicates that the stem bark has antimicrobial properties, as do the leaves to a lesser degree. (“Phytochemical and antimicrobial screening of the crude extracts from the root stem bark and leaves of Vitellaria paradoxa (GAERTN. F)” African Journal of Biotechnology Vol. 6 (16) pp 1905-09; 20^th August 2007)

  Other studies have shown that the butter or oil can be rubbed into the interior of the nose to give relief from nasal congestion and sinusitis for several hours, and the vitamin E content of the butter helps to prevent wrinkles, protect from atmospheric pollutants as well as being a useful sunscreen.

  If you ever get to eat the fruit, which according to some reports tastes a bit like a fig, then you will benefit from its antioxidant properties which are believed to be caused by the catechins (phenolic compounds or bioflavonoids) in it.

  Clearly this tree has potential for future medicinal use as well as being of economic and religious importance to the people in the regions where it grows. The fruit is also important for its vitamin content and nutrition.

JOJOBA PLANT - NOT ONLY FOR HAIR CARE: HISTORY, HEALTH BENEFITS AND USES OF JOJOBA

JOJOBA PLANT, SIMMONDSIA CHINENSIS

Everyone reading this has probably used shampoo or hair conditioner containing jojoba (with the ‘j’ pronounced as ‘h’) oil at some time or another. It is used in the cosmetics industry for hair and skin products.

  It is the only one of its genus and the only one of the Simmondsia family, although it is sometimes put in the Buxaceae or boxwood family. Although its name is Simmondsia chinensis, it is not a native of China, but originated in north western Mexico and southern Arizona and southern California in the US.

  Native Americans and Mexican Indian tribes used the seeds for medicine to treat colds, sores, skin problems, wounds and to promote hair growth. They also used the plant and oil from the seeds as remedies for cancer, obesity, and kidney problems. Apparently it is also effective against poison ivy, warts and relieves sore throats. They ate the seeds either raw or roasted and made a coffee substitute from them too, which is why the fruit is sometimes called coffeeberries. Another name for it is goatnut, as browsing animals such as goats, deer and cattle feed on the young shoots and leaves of this evergreen bush or multi-stemmed tree.

  The jojoba plant has long tap roots so can extract water and minerals from deep below the ground’s surface helping it to survive in arid regions. It can grow to heights of six metres but is often found wild at heights of half to one metre.

  Although it has been used for centuries by indigenous peoples, it came into wider use after the ban on sperm oil in 1971 when a substitute was needed in the cosmetic industry and others. It is now considered to be superior to sperm whale oil, which is just as well for those whales! It was after this ban that jojoba was domesticated in the US and it is now grown in several countries; it can be found in cultivation throughout South America, Israel, the Middle East, South Africa and India.

  The seed meal left after the oil has been extracted is toxic (three toxic glycosides have been identified) and so as yet cannot be used for animal fodder. However research is being done into the oil, which is actually a pale yellow liquid wax and it seems that, like jatropha and Croton tiglium, it could be a useful biodiesel in the future.

  The oil is unique and contains not only fatty acids, as does shea butter which comes from a different continent and tree, but also iodine (usually present in seaweeds such as bladderwrack, laver bread etc.) which is probably responsible for its health benefits for skin, including acne treatment. It also contains vitamin E (useful to smooth out wrinkles and halt the ageing process of the skin) and some B-complex vitamins along with several trace minerals. It also contains 19 amino acids including lysine, typtophan and arginine which means that it has antioxidant properties. The leaves contain flavonoids including isorhamnetin and narcissin. The oil has fungicidal properties and can be used to get rid of mildew.

  Other uses of the oil are in candle-making, the leather industry as transformer oil, plasticizers and fire retardants. In future, if the toxins can be isolated effectively it could have many more uses.

GREAT HAIRY WILLOW HERB - HISTORY OF HEALTH BENEFITS AND POSSIBLE FUTURE USES

GREAT HAIRY WILLOW HERB, EPILOBIUM HIRSUTUM

The Great hairy willow herb is also known as the hairy willow herb and the great willow herb, and is as the name suggests a relative of Epilobium angustifolium or the Rose bay willow herb. It is a member of the Onagraceae family of plants so is also related to the Evening primrose, and the plant does resemble this as you can see from the pictures. It has a hairy stem and leaves, so the genus was given the name hirsutum which means hairy or hirsute in Latin. Its native habitat is in Europe including Britain, Scandinavia, eastern and southern Africa and temperate Asia. In the US it has become naturalized and is another invasive species in some states.

  The leaves are edible and are used in Russia to make tisane, or tea, although there have been reports that the plant and leaves are poisonous. If you do use this plant for any purpose, remember that it could be toxic. It can cause epileptic-like convulsions it is said.

  There are several other local names for this plant in Britain including Son-before–the- Father, which it is called because the seed pods appear before the flowers, or at least it used to seem so to people. It is also called codlings and cream (a codling is an elongated green apple which is used in Britain in cooking). Nicholas Culpeper the 17^th century herbalist says that it was called this because it smelled of apples in milk.

  It is a plant which grows near lakes, ponds and pools and sometimes even in marshes. The flowers appear in June in the UK, and the plant can grow to heights of around 2 metres.

  Culpeper has this to say of its medicinal uses:-

“Governments and virtues. All the species of Willow-Herb have the same virtues; they are under Saturn in Aries, and are cooling and astringent. The root carefully dried and powdered, is good against bloody fluxes, and other hæmorrhages; and the fresh juice is of the same virtue.”

  The leaves have astringent properties, and one study published in 2007 in the Journal of Food Chemistry, “Antioxidant activity and phenolic compounds in 32 selected herbs” by Aneta Wojdylo et al. reported that it was the only one of the plants selected for testing which contained the bioflavonoid myricetin. This is also found in many berries, walnuts, onions and red grapes as well as other plants.

  Myricetin is known to have antioxidant properties so can protect the body’s cells from scavenging free-radicals which can cause cancer. It may also have other anti-cancer effects as well as anti-inflammatory ones, and may also improve bone health and be helpful in cases of diabetes, Parkinson’s disease and Alzheimer’s although a lot more research has to be done to find out what the mechanisms are for these activities.
