Safety & Contraindications

Class 2b, 2d.“Hazards and/or side effects not known for proper therapeutic dosages”. KOM and PH2 report contraindications: peptic ulcer, and nephrosis; not to be used by children younger than 4 years; adverse effects: GI complaints. Since it is viewed as an emmenagogue and uterocontractant, it is contraindicated in pregnancy. Irritation of gastric mucosa may develop following chronic ingestion of large quantities. I suspect that much of what is said here could be said about horseradish, wasabi, and even the milder crucifers, such as the wholesome broccoli, etc.. Plants become bitter in flowering, better for medicine, worse for food.
