How does Broccoli work?

Chemicals in broccoli might have cancer-preventing and antioxidant effects.

Are there safety concerns?

Broccoli is safe when consumed in food amounts. There's not enough information to know if broccoli is safe when taken as medicine. When applied to the skin, broccoli can cause an allergic rash in hypersensitive people.

Do not use broccoli as medicine if:
