CALENDULA

Calendula (Calendula officinalis) is recognized for its antiseptic and anti-inflammatory properties. It is considered one of the most effective herbal remedies for skin problems, such as wounds, rashes, chapped hands, and infections. Calendula is also traditionally used to treat spasms, fever, suppressed menstruation, and other health conditions.

Plant Description

The calendula plant is grown throughout Europe, Western Asia, and the United States. Calendula is an annual (needs to be replanted each year) that thrives in any soil.

Parts Used

Dried flowers are the most important part of the calendula for medicinal purposes.
