Mauritanian mallow also called high mallow (Malva sylvestris spp. Mauritiana L.) is a subspecies of common mallow. It is especially rich in mucilage and the flowers of this subspecies are therefore used extensively in herbal medicine.
The leaves and flower buds contain mucus, tannins, flavonoids, essential oil, vitamin C and other substances. The anthocyanin glycoside malvin, a naturally occurring chemical, is only found in the flowers.
It is also used to treat wounds or inflammation of the mucous membrane in the mouth, throat, stomach, and intestines.
Due to the astringent, bactericidal and anti-inflammatory properties of the plant it can be useful externally as an herbal treatment for wounds, boils, skin rashes, insect bites, pimples, eczema, acne and swellings.
Common mallow has many similar health uses as marshmallow (Althaea officinalis).
