RHATANY or KRAMERIA ROOT, in medicine, the dried root either of Para rhatany or of Peruvian rhatany. The action of rhatany is due to the rhatania-tannic acid, and resembles that of tannic acid, being a powerful astringent. An infusion is used as a gargle for relaxed throats; and lozenges, particularly those containing rhatany and cocaine, are useful in similar cases. Like tannic acid, the powdered extract may be applied as a local haemostatic. Ah 1 preparations of rhatany taken internally are powerful astringents in diarrhoea and intestinal haemorrhage.
