Patient Education

Calendula


What is it? Calendula (Calendula officinalis) is a plant known as pot marigold. It is not the same as ornamental marigolds of the Tagetes genus grown in vegetable gardens.

Calendula is native to Asia and southern Europe and has been traditionally used in Ayurvedic and Unani systems of medicine. The chemicals in calendula might help new tissue grow in wounds and decrease swelling in the mouth and throat.

Calendula flower is commonly used for wounds, rashes, infections, inflammation, and many other conditions. But there's no strong evidence to support the use of calendula for any purpose.
