Uses. - Tamarind, in doses of 1/4 oz. upwards, is both a laxative and refrigerant. The pulp is said to weaken the action of resinous cathartics in general, but it is frequently prescribed with them, and is used in the form of compressed tablets, called 'Tamar Indien,' as a vehicle for the administration of some purgative, probably jalap. A cooling and agreeable drink (tamarind whey) may be made by adding 4 parts of the pulp to 100 of boiling milk, straining and filtering.
