| Notes: | Label source: The drug generally consists of pieces of the root of the tree from 3 to 4 inches long, and from 1 inch to 1/2 inch in diameter. The bark is of a dark brown colour externally, and is studded with numerous little warty projections; the wood i, s white. Sections of the bark show that the paraenchyma contains many cells with red colouring - matter, as well as much starch; towards the inner part of the bark there are numerous large liber cells arranged in two continuous rings. Kala koora, when che, wed, is moderately bitter, it reddens the saliva. These characters are sufficient to distinguish it from Pandhra Kooraor Conessi bark, the produce of Holarrhena antidysenterica, the bark of which has the following characters: very thick, much twisted and, quilled, of a dirty white or dull buff colour, external surface marked by numerous transverse ridges, internal surface longitudinally straited, taste very bitter, does not colour the saliva when chewed. The bark of the stem of W.tinctoria is also met with, in the shops; it is smoother than the root bark, and of a paler colour; it cannot be mistaken for Conessi bark, as it contains much colouring - matter. A full account of the botanical history of these trees will be found in the Pharm. of India p 455. The, seeds of Holarrhena (bitter inderjow) and of Wrightia (sweet inderjow) are always obtainable in the shops. Holarrhena contains an alkaloid which has been named Wrightia. | ||||
