RED HOT POKERS: TALL GARDEN PLANTS WITH HEALTH BENEFITS

RED HOT POKER, KNIPHOFIA UVARIA

I grew up with red hot pokers and goldenrod in the garden, both wonderful plants for bees, and the red hot pokers I know now are full of nectar. In South Africa, where they are a native species, they are eaten and are said to taste like honey. There are many species of these plants which are also called the Torch Lily or Tritoma, some are yellow and lime green others white, but K. uvaria is red-orange with tinges of yellow on the lower flowers.

   They stand tall and are impressive garden flowers in the same way as lupins and hollyhocks are. They are grown in Europe for their beauty and curiosity value, as well as to make an impressive backdrop for smaller flowers. The leaves are evergreen in most species, although in some they die back to grow again in the following year and the flower spikes can grow to around six feet tall.           

  They are members of the sub-family Asphodelaceae and the family of the Xanthorrhoeaceae, and as such are related to the asphodel, bog asphodel and aloe vera. In fact they were thought to be members of the aloe family at first, and were in the genus Aloe uvaria.

   In South Africa the juice of the flowers from this plant is used in cosmetics, and the root is used as a cleanser for the skin to rid it of spots and other skin eruptions. The root is also used in traditional medicine as a medicine to cleanse the uterus and so prepare it for pregnancy.

  An infusion of the root of some Kniphofia species is used for chest complaints such as asthma and bronchitis. Other species figure quite prominently in traditional medicine. Although this one has limited uses it would seem.                                                     

  The Kniphofia genus was named after a distinguished 18^th century German professor at Erfurt University, Johann Hieronymous Kniphof (1704-1763). It consists of more than ten species, which are mainly found in South Africa, although there is one native of Yemen and two or possibly three native to the island of Madagascar. K. uvaria is an invasive weed in some parts of Australia where it was introduced previously as a garden plant.

GARDEN CRESS- SALAD HERB: HEALTH BENEFITS OF GARDEN CRESS

GARDEN CRESS, LEPIDIUM SATIVA 

Garden cress has naturalized in Britain, but may have originated in Iran. It is cultivated across south Asia and is used both as food and medicine. It is a member of the Brassicaceae or Cruciferae family of plants and so is related to savoy cabbage, mustard, cauliflower, red cabbage, kale, kohlrabi, watercress, nasturtiums, field penny cress, broccoli, turnips, swede, horseradish, shepherd’s purse, scurvy-grass and flixweed and many other plants.

  Along with scurvy-grass it is antiscorbutic with a high vitamin C content and also contains good amounts of vitamin A. It also contains the minerals iron and calcium and three of the B-complex vitamins, B1 (thiamin), B2 (Riboflavin) and B3 (niacin).

  It tastes peppery a bit like a peppery parsley, or watercress, and is useful if added to salads in small amounts. The fruits of the plant look a little like capers.         

  It has been shown to be helpful in the treatment of asthma and bronchitis which are two traditional uses for the seeds, which contain oil which is edible and can be used for lighting. Studies have shown that the plant has analgesic (mild pain relief) and anti-inflammatory properties, as well as helping to lower blood pressure. A paste made from the seeds has been used for centuries for relief from rheumatic pains when applied externally on joints. The same paste is used for skin problems.

  In Ayurvedic medicine it is to prevent post-partum problems, and to increase the milk flow in breast-feeding mothers. However the seeds should not be use during pregnancy. In Arabic the herb is known as “Hab–al-Rashood” or “Thufa” and a cold infusion of the seeds is used in some Arab countries to relieve asthma and bronchitis.

     The seeds are also reputed to have aphrodisiac qualities and to improve the quality of a man’s sperm. The plant has diuretic properties and is an expectorant. The woody root has been used to treat secondary syphilis traditionally in Asia.

  One study by F. Kassie published in 2002 showed that the juice or sap of the plant had chemopreventive effects, and it was said that the amounts of the juice needed for these effects to be felt was the same as the amount in the herb used in a salad and eaten in normal amounts.

  There have been several studies of this plant and some are ongoing as they have prove of interest to the medical fraternity.

  The fresh or dried seed pods of the plant may be eaten and used as a condiment or as a flavouring for soups and sauces. The seeds can also be sprouted and used in salads. This may be a good addition to a garden!

BEAR'S BREECHES OR OYSTER PLANT: HISTORY AND HEALTH BENEFITS OF ACANTHUS MOLLIS

BEAR’S BREECHES, OYSTER PLANT, ACANTHUS MOLLIS 

Bear’s breeches is a fanciful name given to this plant which has flowers rather like those of snapdragons. They are pollinated by bees which have to force their way between the top and bottom parts of the flower. They are not relations of snapdragons however, as these are in the Acanthaceae family of plants, so are related to the Marsh Barbel among others.

   Bear’s breeches are native to the Mediterranean region and are cultivated in Britain, although some appear to have naturalized in Cornwall. In the 17^th century, these were called Brank-ursine, meaning bear’s claws, which referred, possibly, to the shape of the flowers. They contain mucilage and tannin, which makes or rather made them useful in traditional medicine systems in Europe.                                                                           

  The plant has been used as a wound healer and internally taken to soothe the mucous membranes in the digestive and urinary tracts. The crushed leaves have been used in poultices and placed on burns or scalds to relieve the pain. The plant has astringent qualities and has been used to treat diarrhea and to heal wounds, as well as being used to clean wounds. It has been taken internally to purify the blood and to calm the stomach. It is also said to have expectorant properties.

  The 17^th century herbalist, Nicholas Culpeper has this to say of the plant he called Brank-ursine: -

“Government and virtues. It is an excellent plant under the dominion of the Moon; I could wish such as are studious would labour to keep it in their gardens. Its leaves being boiled, and used in clysters, is excellent good to mollify the belly, and make the passage slippery; the decoction, drunk, is excellent good for the bloody flux: the leaves being bruised, or rather boiled and applied like a poultice, are exceeding good to unite broken bones, and strengthen joints that have been put out; the decoction of either the leaves or roots being drunk, and the decocted leaves applied to the place, is excellent good for the king's evil that is broken and runneth, for by the influence of the Moon it reviveth the ends of the veins which are relaxed; there is scarcely a better remedy to be applied to such places as are burnt with fire than this is; for it fetcheth out the fire, and healeth it without a scar; it is also an excellent remedy for such as are bursten, being either taken inwardly, or applied to the place; in like manner used, it helps the cramp and the gout; it is excellent good in hectic fevers, and restores radical moisture to such as are in consumptions.“

  Perhaps this plant’s claim to fame is as a motif at the top of Corinthian columns. Vitruvius write in his treatise “On Architecture” that there was a maiden from Corinth who died of a disease. Her grieving family had a monument made to her and her nurse took a basket, filled with the goblets she had loved in life to her grave. She inadvertently placed the basket with a tile covering it to protect the goblets from the ravages of the weather, on a root of Acanthus (mollis or spinosis), so in spring, the plants put forth its leaves and twined them around the basket. The people who passed remarked on the beauty of this and praise the architect who was thus inspired to make other columns for the Corinthians and so the fashion for such columns and their distinctive motif was begun.

  Inspired by these columns the artists of the Renaissance incorporated the leaf from the columns into some of their sculptures and architecture too. Bear’s Breeches thus is important in the history of architecture.

SHIITAKE MUSHROOM - ONE OF THE HEALTHIEST: HEALTH BENEFITS OF SHIITAKE

SHIITAKE MUSHROOMS, LENTINULA EDODES

Shiitake mushrooms have been used in Chinese traditional medicine for thousands of years, and so are classed as medicinal mushrooms rather than culinary ones. They have become a symbol of longevity in Asia because of their health-giving properties.

  They can be used in much the same way as the ubiquitous white mushroom you find on every supermarket shelf, but they have a meaty texture, somewhat like chanterelles and oyster mushrooms but they are highly-prized in Asia, much as we prize truffles and morels in the West. They are relatively small when compared to the Giant puffball.

  Shiitake means wood mushroom, or rather Shii refers to the tree in Japan on which these mushrooms grow naturally, and take means mushroom in Japanese. These mushrooms are also known as “Black Forest mushrooms” as they also grow there in Europe. You can now buy logs impregnated with shiitake spores and grow your own. If you buy fried shiitake you should soak them in hot water to reconstitute them before cooking them or putting them in salads - you can eat them raw.                                                                                     

  Shiitake contain several B-complex vitamins- B2, B3, B5 and B6, and the minerals, magnesium, manganese, phosphorous, selenium, copper and zinc, along with all the 8 essential amino acids, protein and dietary fibre.

  Perhaps the best way of eating these meaty mushrooms is to sauté them for 7 minutes in olive oil to bring out their best flavour and maximize the health-giving nutrients. You can try the side dish recipe below.

  The American Cancer Society has said that lentinam, which is found in shiitake mushrooms, can reduce and slow the growth of some cancer cells and at the same time it boosts the immune system to combat these unwelcome cells too. More trials on humans are needed for us to discover if shiitake mushrooms and their constituents can help in our fight against cancer.

  Selenium, zinc and manganese all have antioxidant properties as do some of the other constituents of these mushrooms, and these combat the scavenging free radicals which can turn cells cancerous. These mushrooms may offer protection from breast, prostate and colon cancers.

  Extracts from the mushrooms have been found to possess antifungal, antibacterial and anti-virus (including HIV-1) properties.

  Shiitake mushrooms can also help prevent rheumatoid arthritis according to one study, and others have shown that they might help with lowering blood cholesterol levels and cardio-vascular diseases, perhaps helping to prevent atherosclerosis.

  Lentin, a protein found in these mushrooms has anti-fungal properties and helps to inhibit the proliferation of cancer cells. L-ergothioneine found in these has potent antioxidant properties.

  If you have gout or kidney problems, be careful - these mushrooms contain purines - you should not eat very many of them in your diet.

SHIITAKE SIDE DISH

This has Taste and is a Treat.

FICUS NOTA, TIBIG: USES AND HEALTH BENEFITS OF FICUS NOTA

TIBIG, WILD PHILIPPINO FIG TREE, FICUS NOTA 

Tibig is the name of this tree in the Philippines, to which it is native; it is also a native of Borneo. It has been introduced to the Hawaiian Islands where it has been cultivated, but it is now seen as an invasive species on some islands. In the Philippines Tibig trees are being planted so that they do not become threatened.

  Tibig is a member of the Ficus genus making it a close relation of the European fig, the tropical fig (Ficus septica), and of course the wild Punjabi fig. It is also related to the peepal tree and the bohar or banyan.As a member of the Moraceae family of plants it is related more distantly to the mulberry and Shahtoot mulberry, the toothbrush or sandpaper tree and to jackfruit.                                                                             

  It is a useful tree as it can be used as hedging as a living fence and because it is a fast-growing evergreen, it is a useful nurse tree for saplings. This tree can grow to 20 metres tall in its native habitat, although they usually grow to around half this size, and is a pioneer species used for reforestation.

  The fruit grows on short stems from the branches and stem of the tree, and is edible, although reportedly the figs are eaten with sugar. The tree is used for firewood and for making charcoal and is also used medicinally in the Philippines. Its white flowers are very small and hard to see.

  When the stem or trunk is cut watery sap exudes from it which is potable, and this is drunk three times a day for fevers, or applied to relieve muscle pains. It would seem that the fruit is not used medicinally, although, no doubt it has laxative properties as do other figs.

THREE OF THE MEADOW RUES: THALICTRUM FLAVUM, T. AQUILEGIFOLIUM AND T.MINUS: INFORMATION

small meadow rue

SMALL MEADOW RUE, GREATER MEADOW RUE AND YELLOW OR COMMON MEADOW RUE

The three meadow rues which are native to the British Isles are Thalictrum flavum, Common meadow rue, or Yellow meadow rue, Thalictrum aquilegifolium, Columbine or Greater meadow rue and Thalictrum minus the small meadow rue. They are not related to the herb rue which is a member of the Rutaceae family, but these are in the Ranunculaceae or buttercup family which makes them relatives of the lesser celandine, stinking hellebore, the Christmas rose, wood anemone, stavesacre, wolfsbane, monkshood, goldenseal and black cohosh.

small meadow rue

   Thalictrum minus is native to Europe, south west Asia and parts of north west Africa and South Africa. Unlike the other two meadow rues it has yellow, plum-brown flowers, rather like the figwort in colour and its foliage is similar to the Maidenhair fern.                                        

   The young leaves of this meadow rue can be cooked and eaten like spinach, although some of the Ranunculaceae family members have some toxicity so caution is recommended. Some research has been done on this plant and some new alkaloids and other compounds have been discovered in it. An infusion of the leaves or a decoction of the root has been used in traditional medicine in the past to help reduce fevers

common meadow rue

  The Common meadow rue has tufty yellow flowers and tends to grow in moist places, such as water meadows, fens and ditches. This is Thalictrum flavum which can grow to over a metre high. It is this one that Nicholas Culpeper the English herbalist who wrote his Herball in the 17^th century mentions thus:-

“Government and virtues. Dioscorides saith, That this herb bruised and applied, perfectly heals old sores, and the distilled water of the herb and flowers doth the like. It is used by some among other pot-herbs to open the body, and make it soluble; but the roots washed clean, and boiled in ale and drank, provokes to stool more than the leaves, but yet very gently. The root boiled in water, and the places of the body most troubled with vermin and lice washed therewith while it is warm, destroys them utterly. In Italy it is used against the plague, and in Saxony against the jaundice, as Camerarius says. A poultice made of the leaves has been known to give ease in the sciatica; and the country people in Buckinghamshire boil the roots and young leaves in ale, and take it as a purge. In smaller doses it works by urine, and removes obstructions of the viscera.”                                                                               

greater meadow rue

  The third meadow rue is Thalictrum aquilegifolium, or Greater Meadow rue, or Columbine meadow rue, the latter name being given to it because of the similarity of its leaves to columbines. This one in also native to North America, where it was used in the 19^th century to flavour spruce beer which was taken as a digestive tonic. It was also used as a purgative and diuretic, so one wonders what happened to those who drank the beer!

  As you can see from the pictures, these three meadow rues are quite distinctive, although all are in the same genus.This last has been used in Chinese medicine for the treatment of respiratory problems such as asthma, in combination with other herbs.

FIELD PENNY-CRESS, ANCIENT WEED WITH BIOFUEL POTENTIAL: HISTORY, USES AND HEALTH BENEFITS OF FIELD PENNY-CRESS

FIELD PENNY-CRESS, THLASPI ARVENSE  

Field penny-cress likes to live in cultivated fields and farmers heartily dislike it as it depletes the nutrients in the soil. However researchers in Illinois believe that it could be a biodiesel and animal fodder crop as its seeds have a high oil yield. This would help scientists in their search for biofuel which comes from a crop which is not a traditional food one, such as soy beans or maize.

  Field pennycress is a native of Europe and was introduced to North America. They also grow in parts of North Africa and Asia. It grows to heights of between eight and sixteen inches (20-40 cms.) and has “winger” seed pods which are round and flattened. This is how it gets its genus name, Thlapsi which is the ancient Greek for “to crush.” Arvense means “of the fields” meaning fields used for crops. Field penny-cress cannot survive in areas of dense vegetation but adores tilled land.                                                   

  It is a member of the Brassicaceae or Cruciferae family of plants making it a relation of mustard, savoy cabbage and others, kale, broccoli, cauliflower, watercress, swede,  turnips, horseradish, kohlrabi, brussel sprouts, shepherd’s purse, scurvy-grass and flixweed to name but a few of its relations. Its leaves are high in protein and vitamin C, and they are said to taste like mustard and onions. In fact the ground seeds have been used as a mustard substitute.

  It has been a notorious weed for centuries and one Finnish law dating from 1734 illustrates this. The law says “Let he who throws wild oats, field penny-cress, or any other weed into his neighbour’s field lose his honour and be fined…and pay compensation for damage.”  This seems a steep penalty for such an action! Clearly field penny-cress was and is a particularly unpleasant weed.

   Indeed, it has a rather unpleasant smell, according to some. However its leaves are edible but slightly bitter when young. These can be added to salads or used as a potherb or added to soups. When the plant comes into flower the leaves are very bitter and unpalatable though. They can also cause gastric problems, so beware.                                       

   The sprouted seed can be added to salads and contains an oil which was used in the past for lighting.

  Other English names for this plant are fanweed, stinkweed and Mithradate mustard. It has been used for the treatment of carbuncles and internal ulcers too, as well as acute appendicitis, as a diaphoretic (promoting sweat in fevers), a diuretic, for rheumatism, as an expectorant, and for liver problems, kidney inflammation, as a blood purifier and an expectorant. It has been found to have antibacterial properties against some bacteria. However, large doses can decrease white blood cell count, so if you use it treat it with care and under the supervision of a physician.

  Perhaps field pennywort will prove a good animal feed/biofuel crop and lose its negative reputation in the near future.
