How does Rhatany work?

Rhatany contains high concentrations of tannins. Astringent chemicals, such as tannins, can reduce inflammation by shrinking tissues and pus.

Are there safety concerns?

Rhatany is POSSIBLY SAFE for most people when taken by mouth for less than two weeks. There isn't enough information to know if it is safe to take long-term or use on the skin. Rhatany can cause some side effects such as digestive complaints. Rarely, rhatany has caused allergic reactions in the linings of the mouth and throat.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of rhatany during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Rhatany allergy: Don't use rhatany if you are allergic to it.

Are there any interactions with medications?



Medications taken by mouth (Oral drugs)
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Rhatany contains a large amount of chemicals called tannins. Tannins absorb substances in the stomach and intestines. Taking rhatany along with medications taken by mouth can decrease how much medicine your body absorbs, and decrease the effectiveness of your medicine. To prevent this interaction, take rhatany at least one hour after medications you take by mouth.
