History
'This tree, in Sanskrit Nimba, is a native of India, and is cultivated in all parts of the country on account of its medicinal properties. The leaves, bark and other products of the Nim have been articles of the Hindu Materia Medica from a very remote period, and are mentioned in the Ayurvedas of Susruta. The bark is considered to be bitter, tonic, and astringent. The leaves are added to poultices to disperse glandular tumours, and are used generally as a discutient; beaten into a pulp they are applied to pustular eruptions, more especially to the eruption of small-pox; their juice is anthelmintic, and is given in a variety of diseases, such as jaundice, purigo, boils, &c. Chakradatta recommends a poultice of the leaves mixed with Sesamum seeds for unhealthy ulcerations. The fruit is described as purgative, emollient, and anthelmintic. The oil of the seeds is applied to suppurating scrofulous glands, is given in leprosy, and a variety of diseases. The gum is said to have stimulant properties. The young trees tapped yield a saccharine juice, which when fermented is used as a stomachic ; several observers have noticed that in certain years this juice appears to flow with unusual abundance. The air waved with a Nim branch is supposed to be a cure for syphilis, hence the Hindustani saying— "Khuda kare nim ki tahni hath men ho." "May God place a nim branch in his hand." Anglice,—"A pox take him." The insane are passed through a cleft of the tree or a stem which having parted and reunited forms a circular opening. This useful tree naturally attracted the attention of the Mahometans upon their arrival in the country, and they named it Azaddarakht-i-Hindi, from its resemblance to the Melia Azedarach or Persian lilac. The author of the Makhzan-el-
Adwiya is careful to point out that the Indian Nim is not found in Persia. He describes the Nim and Azadarakht separately, giving Bakayan as the Indian name for the latter. The quotation from the Makhzan in the Bengal Dispensatory appears to be incorrect, as I can find no such statement under the articles Nim or Azaddarakht. The Mahometans use the different products of the Nim in the same manner as the Hindus, and like them consider it to be cold and dry.

Amongst European physicians, Dr. White, of Bombay, has recommended the bark as a febrifuge; others have spoken favourably of the leaves as a local application to ulcers and certain obstinate skin diseases. Dr. Hove (1787) thus speaks of the Nim tree:— "The Gentoos here worship this tree, and their barren women invoke and perform the same ceremonies round it every morning as they usually do in the other Pergunnahs about the Ficus religiosa. The leaves are of a powerful bitter, and they use a strong decoction with great success in intermittents, and which I usually drank for my liver complaint and found myself much relieved by it." He also notices the use of the gum by lying-in women.— (Hove, account of Mitampoor.) From recent experience detailed in the Pharmacopoeia of India, it would appear that the opinion of the natives of India regarding the medicinal properties of the different parts of this tree is substantially correct. The bark is now official in the above-mentioned Pharmacopoeia.' (Vegetable Materia Medica of Western India, Dymock, 1885)
