Native works on Materia Medica describe the seeds as hot and dry, or according to some cold and dry, laxative, stimulant, and aphrodisiac. They are recommended in leprosy, and other chronic skin diseases which depend upon a vitiated state of the blood, and are given internally and applied externally as a plaster; they are also said to be useful in bilious affections and as an anthelmintic. Ainslie mentions their use in Southern India as a stomachic and deobstruent, and says that they are prescribed in lepra and other inveterate cutaneous affections. He gives Vakoochie as the Sanskrit name. Recently they have been extensively tried in Bombay by Bhao Daji and others as a remedy in leprosy, and I believe with some success. An oleature of Bawachi is prepared and sold by Messrs. Kemp and Co., of Bombay. The plant is a common weed in the Deccan and Bombay, and the, seeds are used in the Concan in making a perfumed oil which is applied to the skin. Dr. Kanny Loll Dey strongly recommends the oleo-resinons extract of the seeds diluted with simple unguents as an application in Leucoderma. He says:— “After application for some days the white patches appear to become red or vascular; sometimes a slightly painful sensation is felt. Occasionally some small vesicles or pimples appear, and if these be allowed to remain undisturbed, they dry up, leaving a dark spot of pigmentary matter, which forms as it were a nucleus. From this point, as well as from the margin of the patch, pigmentary matters gradually develop, which ultimately coalesce with each other, and thus the whole patch disappears. It is also remarkable that the appearance of fresh patches is arrested by its application.”—(Phar. Journ., III. Ser., Sept. 24th 1881.)
Several species of Psoralia have been used medicinally in America, and have been found to act as gentle, stimulating, and tonic nervines. (Stille and Maisch., Nat. Disp.)
