Vacha, derived from the rhizome of Acorus calamus, has a long history of use in traditional Ayurvedic and Chinese medicine, particularly for supporting mental clarity and digestive comfort. Research suggests that bioactive compounds in calamus, including beta-asarone and other sesquiterpenes, may influence neurotransmitter activity and exhibit neuroprotective properties, with preliminary studies exploring its potential role in supporting cognitive function and memory. Studies also indicate that calamus rhizome extracts may help promote healthy digestion by supporting gastric motility and may offer benefits for respiratory wellness through its traditional use as a soothing botanical for the airways. While these findings are promising, much of the current evidence comes from animal and in vitro studies, and further well-designed human clinical trials are needed to better understand its safety profile and efficacy.
