Punarnava: complete India guide

India has one of the highest rates of micronutrient deficiency in the world — and the supplement market is growing fast to meet it. But with hundreds of products on Amazon.in and little regulation, knowing what to actually buy is harder than it should be. This guide covers Punarnava from first principles: what it is, what the evidence says, and how to use it safely in an Indian context.

What is Punarnava?

Punarnava is the root of Boerhavia diffusa, a trailing herb used across Ayurveda, Siddha, and Unani traditions for

Punarnava is relevant for anyone dealing with fluid-retention. It primarily acts on the kidneys.

How does Punarnava work?

The root contains rotenoids (boeravinones), alkaloids (punarnavine), flavonoids, and lignans. In animal models,

Who should take Punarnava?

People seeking traditional Ayurvedic support for kidney function, fluid retention, or liver wellness. Often used in formulations

The typical dose is 300–500 mg of standardized root extract daily. Divided into two doses, morning and evening.

Safety and who should avoid it

Avoid during pregnancy and breastfeeding. Use caution with diuretic medications or if you have existing kidney disease

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 Punarnava

Punarnava works well alongside silybin. The Ayurvedic tradition has long used bhumi amla 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 Punarnava (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 Punarnava supplement is often small — the difference in efficacy is not.

Bottom line

Punarnava has Key citations: PMID 24949473, PMID 15671692, PMID 15036478 for fluid-retention. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
