How does Cabbage work?

Cabbage contains chemicals that are thought to help prevent cancer. Cabbage might change the way estrogen is used in the body, which might reduce the risk of breast cancer. Overall, it isn't well understood how the chemicals in cabbage might work as medicine.

Are there safety concerns?

Cabbage is LIKELY SAFE when consumed in food amounts or when applied to the skin appropriately, short-term. It is POSSIBLY SAFE for most people when taken by mouth in medicinal amounts. There isn't much evidence about possible side effects.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough information about the safety of eating cabbage in medicinal amounts during pregnancy. Stay on the safe side and stick to usual food amounts.

Cabbage is LIKELY SAFE when applied to the skin for a short amount of time while breast-feeding. Applying cabbage leaves to the breasts to relieve swelling and pain due to breast-feeding seems to be safe when done several times a day for a day or two. However, if you are breast-feeding, taking cabbage by mouth is POSSIBLY UNSAFE. Don't eat cabbage even in usual food amounts. There is some evidence that nursing infants can develop colic if their mothers eat cabbage, even as infrequently as once a week.

Diabetes: Cabbage might affect blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use cabbage.

Under-active thyroid gland (hypothyroidism): There is some concern that cabbage might make this condition worse. It's best to avoid cabbage if you have an under-active thyroid gland.

Surgery: Cabbage might affect blood glucose levels and could interfere with blood sugar control during and after surgical procedures. Stop using cabbage at least 2 weeks before a scheduled surgery.
