Berberine is a quaternary ammonia compound found in many botanical products, including goldenseal, barberry and Oregon grape, which is used for its purported antioxidant and antimicrobial properties for a host of conditions, including obesity, diabetes, hyperlipidemia, heart failure, H. pylori infection and colonic adenoma prevention. Berberine has not been linked to serum aminotransferase elevations during therapy nor to instances of clinically apparent liver injury.


Berberine is an isoquinoline alkaloid that is found in many plants and is purported to have antioxidant, antimicrobial, antiinflammatory and antineoplastic activities. It has been used in Ayurvedic as well as traditional Chinese medicine for a wide variety of conditions, including infections, diarrhea, bronchitis and digestive complaints. Berberine is found in many plants and in particularly high concentrations in Hydrastis canadensis (goldenseal), Coptis chinensis (coptis or goldenthread), Berberis aquifolium (Oregon grape), Berberis vulgaris (barberry) and Berberis aristata (tree turmeric). Berberine has been extensively evaluated in vitro and in vivo and demonstrates antioxidant, antiproliferative, and antimicrobial activities. It has been reported to be beneficial in alleviating symptoms of arthritis, in improving glucose control and insulin resistance, in improving hyperlipidemia and lowering blood pressure. Nevertheless, berberine has not been approved for any of these uses in the United States. Berberine is widely available over-the-counter in varying concentrations alone and combined with other herbs and nutritional substances in many multiingredient dietary supplements. The usual recommended dose of the herbal product is 250 to 500 mg two or three times daily. Side effects are few and largely mild and transient gastrointestinal symptoms of nausea, abdominal bloating, diarrhea or constipation. In most controlled studies, adverse events were no more frequent with berberine than with placebo and serious adverse events have been rare.


Berberine has not been linked to serum enzyme elevations during therapy, although there have been few prospective studies in humans that have reported on its effects on laboratory test results in any detail. In published trials, berberine has appeared to be well tolerated with only minor and few adverse effects which have been similar in frequency among persons receiving placebo. Despite wide scale use as an herbal supplement, berberine has not been linked to published instances of clinically apparent liver injury. The frequency of hypersensitivity reactions to berberine is also not known.

Likelihood score: E (unlikely cause of clinically apparent liver injury).

Other Names: Goldenseal, Oregon grape, Tree turmeric.
