Safety information
Toxicity: Berberine-containing. | Ripe berries are food-safe and pleasantly sour. The root/bark/unripe parts are high in berberine, which is contraindicated in pregnancy (berberine can cross the placenta and cause kernicterus risk in neonates) - so the book's 'good in pregnancy' advice is concerning if anything beyond ripe fruit is used. | Ripe berries: safe as food. Root/bark contains berberine and related isoquinoline alkaloids — higher-dose internal use can cause GI upset; isolated berberine has a defined interaction/contraindication profile.
Contraindications: Avoid during pregnancy. | Pregnancy/breastfeeding for berberine-rich parts (root/bark) and supplements; neonatal jaundice risk. | Berberine root preparations: pregnancy and breastfeeding (berberine crosses to the infant, can displace bilirubin → kernicterus risk in neonates; uterine effects) — avoid; neonates/infants.
Interactions: None specifically named (general berberine cautions). | Berberine inhibits CYP enzymes (interacts with many drugs, e.g. ciclosporin) and adds to antidiabetics/antihypertensives. (Safety gate.) | Berberine inhibits CYP3A4/CYP2D6 and P-glycoprotein → raises levels of many drugs (e.g. ciclosporin, midazolam); additive hypoglycaemic effect with antidiabetics and additive hypotensive effect; caution with anticoagulants.
Pregnancy & breastfeeding: Avoid during pregnancy. | Berberine-rich parts contraindicated; book's pregnancy recommendation is concerning. | Berberine root preparations contraindicated (kernicterus risk in neonates; uterine effects).
Evidence level
Supported by clinical trials in humans.
