Herb of the Month: Marsh Mallow - Althea officinalis

By Cristi Nunziata, Herbal Education Coordinator
“Althea comes from the Greek word “althane” to heal.” When you hear the word marshmallow, you make think of the ingredient in S’mores, but Marsh Mallow is actually a medicinal root that has similar benefits to the “at-risk” slippery elm bark. However, Marsh Mallow was used as an early form of marshmallows, as people would steep the roots in honey and roll them into balls to sooth sore throats. Young children were also given the roots to chew on when teething. Unlike the sugary confection, Marsh Mallow root has many healing properties throughout the body.

Marsh Mallow soothes not only sore throats and gums but any irritation or inflammation both internally and externally, particularly in the digestive, respiratory and urinary systems. Traditionally, Marsh Mallow root has been used to treat a range of conditions such as bronchial infections, sore throats, diarrhea, heartburn, urinary tract infections, and ulcers. These soothing properties are due to a water-soluble plant fiber called mucilage. When mucilage comes into contact with water, it becomes a soothing gel. Think of another mallow family plant, okra, to get a sense of what mucilage is like.     Aside from soothing irritated mucous membranes, Marsh Mallow contains pectin. Pectin is a fiber, also found in carrots, apples, rosehips, and figs, which can help balance cholesterol and blood sugar. This soluble plant fiber may also be used to alleviate constipation.

Externally, Marsh Mallow soothes skin irritations. For example, try a soothing bath with Marsh Mallow and Oats. A Marsh Mallow tea gargle may be used for mouth problems or sore throat. Good for the hair as well, look for Dr. Hauschka’s Jojoba and Marsh Mallow conditioner in the Wellness Department.

City Market carries Marsh Mallow root in the Bulk Herbs section. Steeping it in cold water brings out the most mucilage; however, you can also prepare it with hot water as you would any other medicinal herb (see recipe included).
