The marshmallow plant originated in Europe, north Africa, and western Asia. It has a long history of use as both a food and a medicine.

The use of marshmallow root dates back to ancient Egypt, where it was originally mixed with honey for the treatment of sore throat. Marshmallow root is high in a soluble fiber known as mucilage, a thick, gelatinous substance. The mucilage has been used to soften the skin and other cosmetic treatments. Marshmallow root may provide nutritive support for a healthy gastrointestinal and respiratory tract.
