Where does berberine come from?

Berberine is an alkaloid derivative and was first isolated in 1917 from goldenseal (Hydrastis canadensis), also called yellowroot. Goldenseal is an herb of the buttercup family and found in North America. However, when people take goldenseal by mouth very little berberine is absorbed into the bloodstream so study results on berberine may not apply to goldenseal, according to the National Center for Complementary and Integrative Health (NCCIH).

Berberine is found in other plants, such as barberry (Berberis vulgaris L.) and the Amur cork tree (in East Asia). It has a bitter taste and bright yellow color.

Is berberine safe to take?

Berberine appears to have low toxicity at normal doses with stomach effects being the most common complaint; however studies are limited and doses are not well-defined.

• Stomach pain, diarrhea, gas and nausea / vomiting have been reported. Berberine has a bitter taste.
• Other side effects may include dizziness, fainting, headache, and muscle aches.
• Effects on the heart like low blood pressure, slow heart rate, and abnormal heart rhythms may occur with higher doses.
• Allergic reactions have also been reported with berberine use.

According to NCCIH, berberine may cause or worsen jaundice in newborn infants and could lead to a life-threatening problem called kernicterus (a type of brain damage). Do not use this medicine in children unless recommended by your pediatrician.

Does berberine have drug interactions?

Berberine is known to be a weak inhibitor of several cytochrome 450 (CYP450) enzymes (such as 2D6, 3A4, and 2C9). These enzymes are found in the liver and may lead to drug interactions with other prescription or OTC medicines or supplements. Inhibition of liver enzymes may increase levels of medicine in your bloodstream and cause side effects, some of which may be serious.

Berberine may have side effects with medicines used to treat diabetes, heart disease, high cholesterol or high blood pressure, blood thinners like warfarin or medicines that cause drowsiness or sedation.

Caution is warranted with coadministration of potentially toxic medicines such as cyclosporine.

If you choose to use berberine, ask your doctor or pharmacist to review for drug interactions with any medicines you may be taking.
