Gudüci Sattva— 
The process of Sattva (cold water extract)  is not traceable in the Brhat Trayl texts. It is mainly developed during the  medieval period. The process involves, cursing of Gudüci stems and extracting in  the cold water at room temperature (i.e.; without heating). After repeated  extractions the cold- infusion is dried and the obtained solid powder is called  as “Guduci Sattva’. It has been in extensive use in India as a valuable tonic,  alterative and anti-pyretic.
