Calamus root (Acorus calamus) is a major herb for the mind and meditation, and is highly revered by yogis. Ancient yogis and seers used this herb and it is said to stimulate the power of self-expression and to enhance intelligence. Calamus promotes circulation to the brain, sharpens memory, enhances awareness, and increases communication. The yogic name, Vacha, means “speech” and refers to its action on the fifth chakra and its propensity to help you speak from your highest consciousness. This herb is often combined with gotu kola, which is cooling and mild. The complementary energetics makes the combination suitable for a wide variety of people.

Vacha is very popular among my graduate students. When I teach about it in classes at Bastyr University, where I instruct future physicians and natural healing professionals, it always becomes popular within a small cadre of those in the know. For burned out medical students, especially cold, scattered air tattva types, finals week becomes a much easier proposition. Students may also use it for exam phobia.
