Indian Valerian is a perennial plant indigenous to India, and is characterized by its irregularly shaped root. The drug derived from the dried rhizome and rootlets is called Tagar. At one time, it was considered an official medicine and was listed in the Indian and Colonial addendum for use in the Eastern colonies. Tagar is very similar in composition to Valerian, but contains a slightly larger amount of volatile oil. It has stimulant, depressant, sedative, neuroleptic and antispasmodic properties.
