History
'Kushooth is the Arabic name for the Dodders, and from it have been derived tho Greek [?] and Latin Cuscuta of mediaeval writers.

An Arabian poet says:—

" He is like the Kashooth; for he has neither
root, leaves, fragrance, shade or fruit."

In the Indian bazars the name is applied to the fruit of a species of Cuscuta, imported from Persia, and also called Tukm-i-kasus; it is mixed with the small oblong leaves and spines of the plant upon which it has grown, and the flowers and portions of the stem may often be found. The seeds are four in number, light brown, convex
on one side, concave on the other, and enclosed in a nearly globular capsule about the size of a radish seed. The taste is bitter. Mir Muhammad Husain identifies this drug with the Amal-bel, Akus-bel, or Amarlata of India, and describes it as yellow, growing on thorns and other shrubs, and as having a very small, whitish flower, and seeds rather smaller than radish seeds, nearly round, and of a reddish yellow colour. Its proper ties are described as much the same as those of Aftimun. The plant may be either C. hyalina, Roth., C. chinensis, Lam., or C. planijlora, Tenore; possibly several species are collected. In India C. reflexa, Roxb., is sometimes used; it is a larger plant, and has larger fruit than the imported article." (Pharmacographia Indica, Dymock, 1891)
