189. Kamala, much employed by the natives as a dye, is met with in most bazaars in the form of a beautiful purplish-red powder; it should be free from sand or earthy impurities. In medicine, it has attained considerable repute as a remedy for _Tænia or Tape worm_. It has little or no effect on other forms of intestinal worms. The dose for an adult is from 2 to 3 drachms in honey, or a little aromatic water; no other medicine being necessary before or after. In the above doses it acts freely on the bowels, causing, in many instances, considerable nausea and griping, though not generally more than is caused by other remedies of the same class; the worm is generally expelled in a lifeless state in the third or fourth stool. Should the first trial not prove successful, it may be repeated after the interval of a week; but should this be a failure also, it will be useless to continue its use farther; then other remedies may be tried. 190. +Kariyat+ or +Creyat+.

The stem, which is usually sold in the bazaars with the root attached, occurs in pieces of about a foot or more in length, quadrangular, of a lightish-brown colour, and persistent bitter taste. From the similarity between their native names and sensible qualities, this article is often confounded with Chiretta (96). Kariyát is a valuable bitter tonic, and may advantageously be employed in cases of _General Debility_, in _Convalescence after Fevers_, and in _the advanced_ _stages of Dysentery_. It is best given as follows: Take of Kariyát, bruised, ½ ounce, Acorus, or Sweet Flag Root, and Dill Seeds bruised, of each 60 grains; Boiling Water, ½ pint; infuse in a covered vessel for an hour, and strain. Dose, from 1½ to 2 ounces twice or thrice daily. 192. The following preparation has been highly spoken of: Take of Kariyát, cut small, 6 ounces; Myrrh and Aloes, in coarse powder, of each 1 ounce; Brandy, 2 pints. Macerate for seven days in a closed vessel, occasionally shaking it, strain, press, filter, and add sufficient Brandy to make 2 pints. Of this the dose is from one to four teaspoonfuls in a little water taken on an empty stomach. It acts as a gentle aperient, and is said to prove very useful in many forms of _Dyspepsia, especially when attended with torpidity of the bowels_.
