All Berberine-Containing Herbs Should be Avoided During Pregnancy

Monday, 24 November 2008 19:44
Berberine-containing herbs have long been used for their antibiotic action and toning effects on the respiratory tract. Barberry (Berberis vulgaris), goldenseal (Hydrastis canadensis) and Oregon grape (Berberis aquifolium) all contain the antimicrobial phytochemical berberine.

Studies confirm berberine's antimicrobial activity against a wide variety of bacterial, fungal and parasitic species.27 In one study berberine was shown to block streptococci from adhering to epithelial cells, the type of cell found lining the respiratory passages.30 This suggests berberine-containing herbs may be particularly useful in strep infections. Other studies have shown the compound has a protective effect on thymus gland cells31 and supports other immune cells.32 Any of the berberine-containing herbs can be taken on their own, or with echinacea and other immune-supportive herbs. All berberine-containing herbs should be avoided during pregnancy because they may cause premature uterine contractions.
