How does Onion work?

Onion might help reduce cholesterol levels, a risk factor for hardening of the arteries. There is some evidence that onion might also reduce lung tightness in people with asthma.

Are there safety concerns?

Onion is safe when taken in amounts commonly found in food. It might be safe for most people when taken in larger amounts, up to a maximum of 35 mg of the onion ingredient "diphenylamine" per day.

Onion might lower blood sugar. If you have diabetes, check your blood sugar carefully.

Do not take onion if:
  • You are pregnant or breast-feeding, except in amounts used in foods.
