Evidence grade: B · Based on published RCT data

Who should take Vasaka?

The typical dose is 500-1000 mg/day of leaf extract or 2-4 g of leaf powder. Divided into two doses

Safety and who should avoid it

Always consult your doctor before starting any new supplement, particularly if you are on prescription medication or have an existing health condition.

How to combine Vasaka

Vasaka works well alongside thyme leaf. The Ayurvedic tradition has long used guduchi, tulsi for similar purposes — these can complement rather than replace each other.

Buying guide for India

When shopping on Amazon.in, prioritise products that clearly state:

  • The standardised active compound percentage
  • Third-party testing (NSF, USP, or Informed Sport)
  • The form of Vasaka (extract vs whole herb vs isolate)
  • Vegetarian capsule certification if that matters to you

Generic “natural” or “herbal” labels without standardisation information are a red flag. The price difference between a well-made and a poorly-made Vasaka supplement is often small — the difference in efficacy is not.

Bottom line

Vasaka has Key citations: See richResearch section for study filters and participant data. Clinical evidence su for Cough. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
