Frequently asked questions

What is Varuna used for?

Urinary stones above all — it is the classical Ashmari drug — and also difficult urination, prostate enlargement, urinary infection and oedema. It is the principal herb in Ayurvedic urology.

Does Varuna dissolve kidney stones?

It is used to help pass small stones and reduce recurrence rather than to dissolve established ones. A stone causing severe pain, fever or obstructed flow is a urological emergency and needs immediate medical care, not a herb.

What is the dose of Varuna?

Bark powder 3–6 g per day, or decoction 40–80 ml twice daily. It is taken over months for stone prevention, and is usually combined with Gokshura and Pashanabheda.

Can Varuna help prostate symptoms?

It is widely used for the urinary symptoms of prostatic enlargement — hesitancy, weak flow, incomplete emptying — usually with Gokshura. Get the prostate properly assessed rather than assuming the cause of urinary symptoms.

What is Varuna called in Hindi?

Barna or Baruna. In English it is the three-leaved caper or garlic pear tree. The botanical name Crataeva nurvala is sometimes given as Crataeva religiosa.

Are there side effects of Varuna?

Well tolerated at classical doses. Take medical advice if you have kidney disease or are on diuretics. Consult a physician in pregnancy. Increase fluid intake while taking it, as with any drug used for stones.

How long should I take Varuna for stone prevention?

Three to six months is the classical course, alongside adequate fluid intake and dietary change. Recurrent stones need their cause investigated — some types need specific medical management rather than a herbal approach.
