The roots of Viburnum coriaceum were collected from Nilgiri hills, Tamil Nadu, India. A primary organic analysis on the species revealed the presence of bio-active molecules such as tannins, saponins, phenolic compounds (flavonoids) and other phenolic glycosides as their principal phyto- constituents. The crude drug (Patha) was formulated in to an asava using conventional anaerobic fermentation process for about 90 days. Apart from some traditional methods of standardization of asava, a new approach was made to select about thirteen numbers of physical, physic-chemical including organoleptic and primary organic analysis and were attempted with the asava to obtain a reproducible and consistent results and the same were recorded. Since the root asava contained phenolic compounds as principal constituents, a screening for its anthelmintic activities against piperazine citrate induced paralysis p<0.01was significant.
