the world’s oldest medicinal systems, it has been practiced in India for 3,000
Company School Style
In the late 18th and early 19th centuries the East India Company controlled much of the Indian subcontinent. Keen to exploit and export valuable natural commodities, the Company set out to record the flora of India and commissioned Indian artists to create detailed botanical illustrations. Company School style paintings became popular with wealthy Europeans. It was not uncommon for East India Company officials (who were not employed as medics or botanists) to build their own personal collections of paintings depicting Indian flora and fauna.
People behind the paintings
Only 17 of the works are signed. The Indian artists are well known and their works can be found in museums around the globe - Bhawani Das, Ram Das and Sheikh Zain al-Din.
Lady Mary Impey – (1749-1818, wife of the Chief Justice of Bengal) employed all three of these artists to draw the animals in her menagerie as well as India's flora. It is possible that Richard Cresswell simply bought the drawings at auction. However, the works may have come via his wife, Frances Creighton’s, family who almost certainly knew the Impeys.
Plants with culinary uses.
Rambutan (Pulchrifilium spurifolium). Company School, watercolour, about 1800-1810. Two leaf insects (Phyllium bioculatum) are depicted feeding on rambutan leaves. Rambutan fruits look similar to lychees and can be eaten.

It is widely cultivated in tropical and subtropical areas where the young seed pods and leaves are used as vegetables.

The sausage shaped fruits of the tamarind were traded widely in ancient times. Records from the Eastern Mediterranean provide evidence of its cultivation since the 4th Century B.C. Arab sea-traders believe that it resembled the date palm so they combined their name for the date palm 'tamr' with 'hindi', this created the plants common name tamrhindi, upon which its scientific name is based.
Plants with culinary and medical uses.
Taro (Colocasia esculeuta var.antiquorum) Indian School, watercolour, about 1795-1810. Taro is said to be the world’s oldest crop plant, cultivated for its edible tubers, leaf stalks and leaves; it is very easily grown in warm, moist conditions. The tubers are usually eaten cooked to destroy poisonous calcium oxalate crystals. Although they contain more starch than potatoes the starch grains are smaller, which results in a slimy texture. The leaves can be eaten when boiled.
The roots and flower buds are edible, and were eaten particularly in times of famine. Other parts of the plant were used medicinally for a variety of complaints. They contain active chemicals which are said to have psychedelic and aphrodisiac effects. This is a true waterlily, not to be confused with the sacred lotus. They can be told apart by their leaves: in Egyptian lotus and all true waterlilies, the leaves are split to the stalk, whereas in the sacred lotus there is no split.

The leaves, buds and young fruits of capers are said to contain antioxidants, anti-inflammatory and immuno-stimulant compounds. They are a good source of many of the same beneficial substances as are found in cabbage, kale and broccoli. The flower buds are often eaten pickled.
Butterfly pea is frequently used in Ayurvedic medicine, as a memory enhancer, antidepressant and tranquilliser. Different parts of the plant have been shown to have different properties, but an infusion of the roots appears to be most effective.

The rose apple or Malabar plum (Syzygium jambos) is usually grown for its fragrant edible fruit, which may be pale green, yellow or reddish. In spite of the English names, it is related neither to rose, apple or plum, but to myrtle. The simple leaves, flowers with masses of long, thin stamens and fruit with the remains of sepals at the tip, are characters of the myrtle family. Many parts of the plant have long been used in traditional medicine to treat a number of ills.
India is one of the largest silk-producing countries in the world. Silk is produced by boiling silk moth cocoons to release the long fibres the caterpillar made them from. The silk is then spun onto a reel. This caterpillar is probably the South India small tussore moth which produces ‘tussar’ or ‘tasseh’ silk. Tussar silk is coarser, but stronger than common silk, and is naturally reddish-brown in colour. William Roxburgh and his wife studied this moth and in 1797 he wrote a paper on the possible commercialisation of this silk for Sir Joseph Banks and the East India Company. It belongs to a different family from the Chinese silk moth (Bombyx mori) which has hairless, white caterpillars and feeds primarily on the white mulberry. The fruits of the jujube tree turn red as they ripen and are often dried and candied, used for making teas and have numerous medicinal uses, particularly in relieving stress.

The fruits and male flowers are eaten raw, boiled, steamed or roasted. The tree is also valued for its hard, termite-resistant timber that is used for everything from firewood to heavy construction. The wood and roots yield a useful dye and the sticky latex sap has a variety of uses. In Nepal the leaves are fed to lactating animals due to their high protein content.
Shampoo ginger rhizomes are traditionally used to treat a variety of ailments including stomach ache and worms. Zerumbone, an aromatic compound found mainly in the leaves, is being investigated as an anti-tumour agent.

Plants with other uses.
Flame-of-the-forest or dhak tree (Butea monosperma). Indian School, watercolour, about 1795-1810. True cochineal is a very valuable product. Cochineal is a red dye formed by crushing insects that feed on the Mexican prickly pear cactus. In a similar way, the eggs of the lac insects (Laccifer lacca or Kerria lacca) that feed on the ruby-coloured gum of the dhak tree can be crushed to make a dye. In the 1790s the East India Company hoped that this might be used as a substitute for cochineal but it was not a profitable venture.
