Churnams are single dravyas that are finely ground and strained through a fine sieve. The result is a fine light powder that easily absorbs. Single churnams are combined to make traditional formulations. Churnams are the main components for kashayas, kwathams, arishtams, lehams, oils, and ghritams. Some churnams are produced for internal use while others are for external use only. There are five aqueous extracts known as the pañca kaṣāya.
