DHAK OR FLAME OF THE FOREST TREE-HOST TO LAC INSECTS: HISTORY,USES AND HEALTH BENEFITS OF THE DHAK TREE

DHAK TREE, FLAME OF THE FOREST, PARROT TREE, BUTEA MONOSPERMA 

The dhak or flame of the forest tree is a member of the Fabaceae or Leguminoseae (beans and peas) family of plants which include kudzu or pueraria, senna, alfalfa, carob, broom, lupins, chickpeas and peanuts to name just a few. Like the red silk cotton tree (Bombax ceiba) it flowers when the tree is bare of its leaves, so it looks like a flame tree with its bright red blossoms. The tree grows to between 12 and 15 metres high and flowers in the winter months between January and March.

 The site’s administrator remembers a time when he was in a village elementary school in Pakistan and a new teacher came. The leader of the group of children decided that they should all come to school the next day with a petal from the flowers of this tree attached to their little fingers. The schoolteacher didn’t know what the things on their one finger were but the kids explained that it was a custom for them to wear their nails long and red on one finger. He said that in future this would not be acceptable for boys, and told them to go home and cut their nails and remove the red. They turned up after a game of cricket, with no petal attached to their fingers. They had attached them with saliva.

  The flame of the forest tree is host to lac insects (Tachardia lacca) which feed on the tree sap and secrete a resinous substance to protect themselves and their offspring. This is formed on the twigs and branches of certain trees such as Acacia nilotica or babul tree, Zizyphus jujube(a jujube {ber}bearing tree) , Zizyphus xylopyrus, Ficus religiosa or peepal and Schliechera oleosa the macassar oil tree or kusum tree. In the past these trees were cultivated to play host to the lac insect as shellac was in demand as a varnish or lacquer (we get this name from these insects). The flame of the forest tree has been cultivated for such a purpose since at least 250 AD when only a red dye from this insect was of value. By 1590 the resin was more important than the dye.

  The tree is used for medicinal purposes wherever it grows, and its natural habitat is the Indian subcontinent and tropical and sub-tropical south-east Asia. It is also known as Palash, Palah and bastard teak. Its wood is durable under water and is sometimes used in wells and for water scoops. The leaves are woven to make plates, rather as the single banana leaf is used in countries such as Thailand. The flowers are used to make a red colouring used in holi.

  In Hindu legends the tree is said to be the physical embodiment of Agnidev, the God of Fire who was punished by the goddess Parvati for daring to disturb the privacy she was enjoying with Shiva. The flowers are used in ceremonies for the goddess Kali with their red being the symbolic sacrifice instead of a human one. The dry twigs and branches make the sacred fire required in such ceremonies.

  Mosquitoes are attracted to the flowers, and lay eggs that will never hatch in them, and the mosquito also dies, trapped in the flowers’ liquid. The gum from the tree is used in some dishes but is astringent as it contains tannin. It has been used to treat leather and used for its astringent qualities in medicine. Wood from the tree is used for fuel and it also produces good charcoal which is why it is becoming a threatened species in Pakistan.

  The mucilage from the tree is used to treat asthma in traditional medicines systems, while the flowers are used for menstrual problems, to reduce swellings, as a diuretic and aphrodisiac, a tonic and to treat recurring gout and even leprosy. The seeds which are single in pods are used to get rid of internal worms, and the leaves are astringent and used as a tonic, diuretic, aphrodisiac, and to get rid of boils and pimples, tumours and piles.

  A decoction of the bark is used for colds and sore throats as a gargle, as well as for coughs, fevers and to promote the menstrual flow. The root of the tree is used in cases of elephantiasis and night blindness while the gum is specifically used for diarrhoea, dysentery and ringworm.  Fresh juice from the tree is used externally on boils and ulcers and internally for sore throats.

  The succulent edible young roots may be eaten raw with salt or roasted or boiled and contain glucose, glycine, glucosides and aromatic compounds while the seeds produce oil. The seeds are pounded with lemon juice and applied to the skin for various problems.

  The seeds may be abortifacient and are may form the basis in coming years of a male contraceptive. The different parts of the tree are still being researched, as the dhak tree may provide us with many health benefits.

COMMON SAND SPURRY - EDIBLE PLANT : HEALTH BENEFITS OF COMMON SAND SPURRY

COMMON SAND SPURRY, ARENARIA RUBRA

As its name suggest, common sand spurry like to grow in sandy soils. There are two types, one which grows inland and one which grows near the coast. It is also known as Spergularia rubra, while the sea-loving one is Spergularia marina. Another common name for the plant is sandwort.

  It is common in Europe and North America, and has pink or sometimes white flowers. Its seeds are edible and in times of famine can be roasted or boiled then ground into meal and mixed with wheat flour.

  It is a member of the Carophyllaceae family of plants, making it a relation of carnations cloves, soapwort and reetha or soapnut.

  It is in this website because it has a reputation for being a lithotropic, meaning that it has been used in traditional medicine for centuries to disperse stones in the kidneys and bladder. It is thought that the infusion of the whole plant, or at least, the aerial parts, relaxes the muscle walls in the urinary tract and increases urine production so that stones are more easily flushed out of the bladder.

  It is common in Malta, Sicily, Algeria and most of Europe, and is related to the sea-marsh sand spurry which is native to North America and which has been used medicinally for the same purposes.

  

AGAR-AGAR - THE VEGETARIAN GELLING AGENT: PRODUCTION, USES AND HEALTH BENEFITS OF AGAR-AGAR

AGAR-AGAR, GELIDIUM AMANSII

Agar-agar is vegetarian gelatine, made from a red seaweed. The best is thought to come from Gelidium amansii, although it can also be extracted from other algae such as those in the genus Gracilaria lichenoides which is found off the west cost of the USA and parts of the Asian coast. Other red algae used for agar-agar are those of the Pteroladia genus. Gelidium amansii is notable for the spiky projections which come from the main branches of the plant.

  A jelly made from agar-agar flavoured with lemon used to be food fit for invalids in the 19^th and early 20^th centuries, although now it is usually not used in medicine. It does have use as a mild laxative however, as it plumps up in water and in the gut, so can help to remove toxins, fats and sugars from it. You can mix it with fruit juice or milk for this purpose, and shreds of it are better than powder. It will work similarly to isphagol or plantain.

  Agar-agar can retain moisture, and so is used in the laboratory as a solidifying component of bacteriological culture. It is used in the food industry and like annatto and gum Tragacanth has an E number, E406. It is used in the food industry and can be found in canned meat products, as well as in medicines and cosmetics. It is also used in dentistry and in the brewing industry where it is used to clarify beer and wines. You can also find it in ice cream and in salad dressings, as it is used as a thickening agent.

  It is believed that the Dutch brought it to the attention of other European nations, after they had taken it from Japan to their colonies in Indonesia, as they had “open ports” in Japan in the 17^th century. The Japanese and Chinese are believed to have been the first people to develop agar-agar from red seaweed.

  Now it is made in Australia, the US, Japan, New Zealand and Russia. After the BSE (mad cow disease) it became more widely used as it is a safe alternative to jelly or gelatine made with parts of the cow.

  As you would expect from an algae, it is rich in iodine and trace minerals, as are laver bread and bladderwrack. You can buy it in transparent strips or powder and use it for aspic jelly. 

DRAGON TREE -ONE OF SEVERAL PRODUCERS OF "DRAGON'S BLOOD": HISTORY, USES AND HEALTH BENEFITS OF THE DRAGON TREE

DRAGON TREE, DAEMONOROPS DRACO

This tree is native to Sumatra, Borneo and Malaya, and is a palm, a member of the Arecaeae family along with the toddy palm and others. Its main claim to fame is that it provides us with Dragon’s blood which is a resinous substances exuded from its fruit. This tree has catkin-like flowers which are followed by fruit which are pointed cherry-sized berries, with a coating of a reddish resin when ripe. It is this that produces Dragon’s blood. We have few pictures for this tree as other trees bearing dragon’s blood are more popular it would seem, some form the Canary Islands, one from Yemen but this one is of Asian origin.

  The resin is steamed from the fruit or the fruit are boiled, but the resin made in this way is deemed inferior. It used to be used in medicine for its astringent properties and was used against diarrhoea and syphilis.

Dragon' blood resin

  Dragon’s blood comes in tear shapes or in sticks, which were packed in leaves and strips of cane. Today however the tree is over-exploited and used to make rattan furniture and to make Dragon’s Blood ink which is used for witches seals and talismans. It is also used as a body oil and for incense.

  In traditional Chinese medicine it is used to control bleeding and pain, and to improve blood circulation as well as to promote wound healing and tissue regeneration.

  It is also used in varnishes (violin varnish) and was used in China to colour the surface of writing quality paper to make banners and posters for weddings and Chinese New Year.

  This tree is the main source of commercially harvested Dragon’s Blood.

  It gets a mention in this blog site because there has been research conducted into it, and it seems that it has exhibited antimicrobial and antiviral properties in vitro. It contains benzoic acid which has antiseptic properties and dracorhodin extracted from its fruits has been reported to induce human melanoma cell death, again in vitro. Research is still underway to reveal the secrets of the fruit and new flavonoids have been isolated from it, although their properties are still unreported. Although it is early days yet, scientists hope that it may have promising uses against cancer.
