Rhatany (Krameria triandra) is a plant that is fairly uncommon. The root is used as medicine. Some rhatany products might not contain the correct plant. Related plants (other Krameria species) are sometimes used in place of rhatany, but are not stated on the label.

People use rhatany for intestinal swelling (enteritis), chest pain (angina), and for mild mouth and throat irritation, but there is no good scientific evidence to support these or other uses.
When taken by mouth: There isn't enough reliable information to know if rhatany is safe when used as medicine. Rhatany can cause stomach upset.

When applied to the skin: Rhatany is POSSIBLY SAFE for most people when applied to the skin for less than two weeks. There isn't enough reliable information to know if it is safe to use on the skin for longer than 2 weeks. Rarely, rhatany has caused allergic reactions in the lining of the mouth and throat.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if rhatany is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Rhatany allergy: Rhatany has caused allergic reactions in the lining of the mouth and throat. Don't use rhatany if you are allergic to it.
