Modern research
Contemporary clinical and pharmacological reviews (see references) explore Punarnava's role in the areas where Ayurveda has traditionally used it. Evidence quality varies; treat single studies with caution and prefer systematic reviews.
Safety notes — read before use
As with all traditional herbs, avoid in active flare-ups of the condition you're treating and in anyone with a known allergy to the plant family. Stop and seek medical advice if you develop rash, breathing changes, swelling, digestive upset or any new symptom after starting.
