Although it is a mint, it is not a culinary herb. The RHS says it is harmful if eaten and not edible. It contains pulegone, which damages the liver, and people have been poisoned after mistaking it for culinary mint. It should not be used in pregnancy, and it is toxic to cats. Wear gloves when handling it and keep pets away from it.\u003c\/p\u003e\n\u003ch2\u003eIs it legal to grow?\u003c\/h2\u003e\n\u003cp\u003eYes, as nursery-grown stock.
