Stem bark, root bark, berries.


Barberry contains isoquinoline alkaloids, including berberine and berbamine. Berberine is strongly antibacterial and amoebicidal, and stimulates bile secretion. Berbamine is strongly antibacterial. Many of the alkaloids are thought to be cancer-inhibiting.

History & Folklore

In ancient Egypt, Berberis berries were macerated with fennel seed (Foeniculum vulgare) to make a drink for fevers. The berries are extremely sour but have been used in the past to make preserves—the French confiture d’épine vinette is one example.

Medicinal Actions & Uses

Barberry acts on the gallbladder to improve bile flow and ameliorate conditions such as gallbladder pain, gallstones, and jaundice. Its strongly antiseptic property helps amoebic dysentery, cholera, and other similar gastrointestinal infections. The bark is astringent, anti-diarrheal, and healing to the intestinal wall—in short, barberry has a strong, highly beneficial effect on the digestive system as a whole.

Like Oregon grape (B. aquifolium, preceding entry) and goldenseal (Hydrastis canadensis), barberry helps chronic skin conditions such as eczema and psoriasis. The decoction makes a gentle and effective wash for the eyes, although it must be diluted sufficiently before use.


Berberine has been shown to have antibiotic activity against cholera, giardia, shigella, salmonella, and E. coli.
