Bhumyamalaki (Phyllanthus Amarus): Traditional Uses for Liver Support
A small marshland herb, almost invisible, yet one of the few Ayurvedic liver herbs to have been tested in published Western clinical trials. Here is what tradition really says — and what the science really says.
Bhumyamalaki (Phyllanthus amarus, sometimes Phyllanthus niruri depending on the region) is a small annual herb common in humid tropical areas, classed by Ayurvedic texts among the "yakrit uttejaka" — literally, the herbs that stimulate the liver. Its name means "amla that grows on the ground," a nod to its discreet resemblance to amla. It is also sold in the West under the commercial name "bhumy amla."
In practical terms: a herb traditionally reserved for the liver, urinary tract and fevers, with the rare distinction of having been tested in published clinical trials — provided the results are read with the nuance they deserve, without turning it into a miracle liver cure.
What are the traditional uses of bhumyamalaki?
- Liver: this is the herb's most emblematic use in Ayurveda and in South Asian folk medicine, where it is traditionally employed for jaundice and liver disorders.
- Urinary tract: traditional use as a mild diuretic, for urinary discomfort or stones, often combined with other herbs.
- Fever: tradition also uses it as a febrifuge, particularly for fevers accompanied by digestive trouble.
- Digestion: its light bitterness makes it a gentle digestive stimulant, in the same family of logic as kalmegh, though more moderate.
In the Ayurvedic framework, bhumyamalaki is classed as bitter, astringent and cooling, which makes it an herb that pacifies Pitta and Kapha in particular. It fits the same logic as the gentle ama detox approach described elsewhere on this site, without being an express liver "cleanse."
What does research show about bhumyamalaki and the liver?
Bhumyamalaki owes its Western reputation to a clinical trial published in 1988 in The Lancet by an Indo-American team (Thyagarajan et al.), involving chronic carriers of the hepatitis B virus. Of 37 patients treated with a Phyllanthus amarus extract for 30 days, 22 (59%) had lost the virus's surface antigen at follow-up, compared with only 1 of 23 (4%) in the placebo group — a striking result for a pilot study of this size.
This result sparked enormous interest, but later attempts at reproduction by other teams did not all find such a clear effect, and more recent systematic reviews of the Phyllanthus genus in hepatitis B conclude that the data remain heterogeneous and insufficient to recommend the herb as a treatment for viral hepatitis. In other words: a genuine and intriguing historical signal, but one that has never been confirmed to the level of evidence that would be required to use it in place of hepatology follow-up.

How is bhumyamalaki taken? Forms and dosage
As a rough guide — traditional uses, to be validated with a health professional, especially in the case of a known liver condition:
| Form | Usual dose | Notes |
|---|---|---|
| Whole-herb powder | 1 to 3 g per day | Diluted in warm water, between meals |
| Standardized extract | Per manufacturer's label | Short course of a few weeks, not continuous |
| Traditional decoction | Freshly prepared | Classic form, reserved for supervised use |
Tradition favors courses of a few weeks, reassessed regularly, rather than year-round continuous intake — a logic already detailed for triphala and most of the background herbs on this site.
Precautions and contraindications
- Active liver disease: never self-medicate with a diagnosed liver condition (hepatitis, cirrhosis); bhumyamalaki does not substitute for any treatment and requires prior medical advice.
- Pregnancy and breastfeeding: to be avoided as a precaution, for lack of sufficient human safety data.
- Diabetes and hypertension: theoretical interactions possible with diabetes and blood-pressure medication; medical advice recommended before a course.
- Children: use reserved for supervision by a qualified practitioner.
General safety guidance is detailed in our safety and precautions guide.
Bhumyamalaki or kalmegh: which herb for the liver?
The two herbs overlap partially: kalmegh is mainly documented for respiratory infections and immunity, with a secondary liver action, while bhumyamalaki is specifically centered on the liver in both tradition and available research. Neither replaces medical follow-up for a genuine liver disorder: the best way to "take care of your liver" according to both Ayurveda and modern medicine remains, first and foremost, a diet moderate in fat and alcohol, a stable weight and regular screening rather than a self-medicated herb.
Your questions about bhumyamalaki (phyllanthus amarus)
Does bhumyamalaki cure hepatitis B?
No. A clinical trial published in The Lancet in 1988 showed an encouraging result on loss of the virus's surface antigen, but later work did not all confirm this effect, and recent systematic reviews judge the data insufficient. Hepatitis B is diagnosed and monitored medically, never through self-medication.
What is the difference between bhumyamalaki and amla?
The name bhumyamalaki means "amla that grows on the ground," referring to a visual resemblance, but they are two botanically different plants. Amla is a vitamin-C-rich fruit used mainly for immunity and hair, while bhumyamalaki is a small herb centered on the liver and urinary tract.
Can bhumyamalaki be taken preventively, without a liver problem?
Tradition sometimes considers a short maintenance course, but no data justifies continuous intake in a healthy person. A balanced diet and moderate lifestyle remain the first recognized levers for liver health.
Is bhumyamalaki dangerous for the liver at high doses?
Human safety data remain limited, particularly for prolonged courses. In case of liver disease, any use should be discussed with a doctor before starting, and a course should never delay a necessary treatment or hepatology follow-up.
