Frequently Asked Questions

Is Vacha safe?

Vacha is safe in traditional Ayurvedic doses (250-500mg). The concern about beta-asarone relates to very high doses used in laboratory studies. In the small amounts traditionally prescribed, it has been safely used for thousands of years. Always use under practitioner guidance.

Can Vacha improve public speaking?

Vacha has been the go-to herb for speech enhancement for millennia — from Vedic chanters to courtly orators. It clears mental fog, improves verbal fluency, and reduces speech anxiety. Combined with Brahmi for best cognitive-speech support.
