Overview

Overview Information

Kohlrabi is a vegetable that is similar to cabbage, broccoli, cauliflower, kale, collard, and Brussels sprout. The stem and leaves of kohlrabi are eaten as food and as a medicine.

Kohlrabi is taken by mouth as an antioxidant and for cancer, heart disease, constipation, diabetes, gout, hemorrhoids, hot flashes, high cholesterol, liver disease, menstrual symptoms, a pain disorder called sciatica, scurvy, weight loss, and wound healing.

Kohlrabi is applied to the skin for hair loss.

How does it work?

Kohlrabi contains chemicals that are thought to help prevent cancer. Chemicals in kohlrabi might also have antioxidant activity.
