Kutki (Picrorhiza Kurroa)

A Himalayan bitter root used in Ayurveda for the liver. Its main compound, picroliv, has genuine hepatoprotective activity in animals, but the human evidence rests on one small trial from the 1990s.

What the science says

Liver protection in viral hepatitis Limited evidence
A randomised clinical study published in 1996 tested Picrorhiza kurroa as a hepatoprotective agent alongside experimental work and reported faster normalisation of liver markers. It was a single small trial, decades old, and has not been replicated with modern methods.
Picroliv activity is preclinical Limited evidence
Pharmacology reviews describe consistent hepatoprotective, choleretic and antioxidant effects of picroliv against toxin-induced liver injury. All of this work is in rodents and cell systems; none of it demonstrates benefit for fatty liver or any human liver disease.

Dosage & safety

Studied doseTraditional dosing is roughly 0.5–2 g/day of root powder; extract capsules typically state 300–500 mg/day. No modern dose-finding study exists.

SafetyIntensely bitter and can cause nausea and diarrhoea. The plant is endangered and heavily adulterated, so identity and purity are real concerns. Do not use it to self-treat liver disease — herbal products are themselves a leading cause of drug-induced liver injury, and liver symptoms need a diagnosis. Avoid in pregnancy and breastfeeding.

How to take it

TimingTraditionally taken before meals, which is where the bitter digestive effect is claimed to sit.

With food?Take with a little food or water if the bitterness causes nausea.

Worth knowingBuy only from suppliers that publish botanical identity testing — Picrorhiza kurroa is endangered and heavily substituted, so what is in the capsule is often not what is on the label.

Frequently asked questions

Does kutki protect the liver?

Kutki's compound picroliv protects the liver in rodents, but the human evidence rests on one small trial from 1996 that has never been replicated, so the grade is limited. Nothing shows kutki helps fatty liver or any human liver disease.

Should you use kutki for fatty liver?

No. Do not use kutki to self-treat liver disease; herbal products are themselves a leading cause of drug-induced liver injury, and liver symptoms need a diagnosis.

How much kutki per day?

Traditional dosing is roughly 0.5–2 g/day of kutki root powder, and extract capsules typically state 300–500 mg/day; no modern dose-finding study exists. Kutki is intensely bitter and can cause nausea and diarrhoea.

Is kutki often adulterated?

Yes. Picrorhiza kurroa is endangered and heavily substituted, so buy kutki only from suppliers that publish botanical identity testing.
