Calendula is used externally as a tea, in baths or salves, and for skin issues. It is not related to the common garden Marigold, although it is commonly called Pot Marigold.
Traditionally used as a gargle for helping to reduce inflammation of the mouth, throat, and tonsils, this colorful herb has many soothing and healing properties. Calendula is most frequently used externally on wounds, burns, sensitive skin and for first aid purposes, as it may help soothe and rejuvenate the skin.
Common names: Calendula, Pot Marigold
Excerpts from The Green Pharmacy Herbal Handbook
"With those bright, yellow orange flowers, you might mistake Calendula Flowers for any other marigold. But calendula is actually an entirely different plant. It's native to northern Africa and the south-central portion of Europe, but it can be grown elsewhere, including indoors. If you can't visually distinguish calendula flowers from marigold, you'll probably be more successful using your nose: regular garden marigolds give off a strong, unpleasant aroma (although some people like it); calendula flowers are comparatively milder. Therapeutic uses for calendula flowers include burns, inflammation, mucositis, and pharyngitis."
Excerpts from Practical Herbalism
"Calendula is a remedy long used throughout Europe and the Americas for wound healing and ulcer treatments. Culpeper speaks of the flowers, either fresh or dried, as being 'much used in possets, broth, and drink as a comforter of the heart and spirits, and to expel any malignant or pestilential quality which might annoy them.'"
