How does Isatis work?

Isatis might be able to fight bacteria and viruses that can cause infections. It also seems to be able to reduce fever and swelling. There is some interest in using isatis for cancer because it contains chemicals that might keep cancer cells from multiplying.

Are there safety concerns?

Isatis is POSSIBLY SAFE when applied to the skin appropriately, short-term. A specific product containing the isatis constituent indigo naturalis as an oil extract (Lindioil), applied to the skin in doses of 0.05 to 0.1 mL twice daily, has been used safely for 24 weeks.

There isn't enough reliable information available to know if taking isatis by mouth is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking isatis if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Aspirin allergy: Isatis contains chemicals that are similar to the chemicals in aspirin. There is a concern that isatis might trigger an asthma attack or an allergic reaction in people who are allergic to aspirin.

Dosing considerations for Isatis.

The following dose has been studied in scientific research:

  • For scaly, itchy skin (psoriasis): A specific product containing a chemical in isatis called indigo naturalis as an oil extract (Lindioil), applied in doses of 0.05-0.01 mL to nail folds and the skin beneath the edge of the nail twice daily for 24 weeks, has been used.
