Overview

Vacha is one of the herbs traditionally used in Ayurveda for brain fog & memory problems. Vacha literally means ‘speech’. Calamus thrives in wet, damp marshland and is a semi-aquatic perennial. Its qualities treat similar ‘terrain’ in the whole system; sluggish, congested, heavy and wet conditions, like those of a marshland, are opposed by the warm, drying, penetrating and stimulating qualities of vacha.
