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.

Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

More evidence is needed to rate the effectiveness of kohlrabi for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Side Effects

Kohlrabi is LIKELY SAFE when consumed in food amounts. It isn't known if kohlrabi is safe or what the possible side effects might be when taken in medicinal amounts.

Special Precautions & Warnings

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


The appropriate dose of kohlrabi depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for kohlrabi. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
