Safety information
Toxicity: Notable. Contains galegine and related guanidines; the fresh plant is toxic (livestock poisoning - pulmonary oedema, hypotension, death in grazing animals at high intake), so only properly dried material is used. Galegine can cause hypoglycaemia.
Contraindications: Diabetes / hypoglycaemia-prone individuals - risk of additive blood-sugar lowering. Pregnancy. Caution in lactation (limited infant-safety data). Hypotension. Avoid fresh plant entirely.
Interactions: Antidiabetic drugs (insulin, sulfonylureas, metformin, etc.) - additive hypoglycaemia risk; other glucose-lowering herbs likewise. Possible additive hypotension.
Pregnancy & breastfeeding: contraindicated in pregnancy; caution in lactation (limited infant-safety data)
Evidence level
