Marshmallow root and leaf have a high mucilage content, which calms inflammation, nourishes bone marrow, soothes and moistens the skin, and promotes tissue healing. Marshmallow is especially useful in soothing irritation in the respiratory, urinary, and gastrointestinal tracts. As a tonifying herb, it can aid children’s growth and development. It also can help calm an overactive immune system and, because it helps stimulate white blood cell production, can function as an immune tonic. It decreases the nerve sensitivity that causes coughs.

Brief History

Althaea officinalisThe plant’s history as a medicinal goes back to Theophrastus (372-286BC) who reported that marshmallow root was taken in sweet wine for coughs. Hippocrates prescribed a decoction of marshmallow roots to treat bruises and blood loss from wounds. The Greek physician Dioscorides recommended marshmallow root poultices for insect bites and stings and prescribed the decoction for toothache and vomiting and as an antidote to poisons.

10th-century Arab physicians used mallow leaf poultices to treat inflammations, and early European folk healers used marshmallow root both internally and externally for its soothing action in addressing toothache, sore throat, digestive upsets, and urinary irritation. Culpeper recommended it, and by the mid-19th century, it was included in the U.S. Pharmacopoeia. In the 9th century, Emperor Charlemagne ordered marshmallow cultivated in his monasteries.

Primary Uses

Cough and Laryngitis

Approximately 35 percent of the weight of the marshmallow root comes from mucilage, which coats irritated linings of the mouth and throat. Since this mucilage acts in the same way as natural mucus, it prevents cough rather than stimulating the release of mucus. Therefore, marshmallow root is appropriate for dry, hacking coughs rather than for relieving congestion. In addition, the herb is known to stimulate phagocytosis, the immune process in which cells called macrophages engulf and digest infectious microorganisms.

Stomach Ailments

Teas of marshmallow root contain complex polysaccharides that form a protective layer on the stomach lining. These polysaccharides swell to twelve to fifteen times their original volume when they meet the fluids of the stomach, completely coating its lining.
