| Notes: | Label source: The drug generally consists of pieces of the root of the tree from three to four inches long, and from one inch to half inch in diameter. The bark is of a dark brown colour externally, and is studded with numerous little warty projections;, the wood is white. Sections of the bark show that the parenchyma contains many cells filled 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 chewed, is moderately bitter; it reddens the saliva. These characters are sufficient to distinguish it from Pandhra Koora, or Conessi Bark, the produce of Holarrhena antidysentica, the bark of which has the following characters - very thick muc, h twisted and quilled, of a dirty white or dull buff colour, external surface marked by numerous transverse ridges, internal surface longitudinally striated, taste very bitter, does not colour the saliva when chewed. The bark of the stem of W. tinctoria i, s 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 Indi, a p455. 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. | ||||
