Safety information

Contraindications: None at food use. Caution: alcohol content of extracts (recovering alcoholics, very young children in large amounts). Possible allergy in sensitized individuals/handlers.
Interactions: None established at culinary amounts.
Evidence level
Supported by laboratory or animal studies; not yet confirmed in humans.
