Marshmallow root has long been used as a food, particularly during times of famine when it is more abundant than other vegetables. Medicinally, it has been approved by the German Commission E in supporting inflammation of the gastric mucosa, and for irritation of the oral and pharyngeal mucosa. When combined with other herbs, it is additionally used for mild respiratory symptoms, including cough. The root is traditionally used to support a healthy digestive system. It is unique in that when making a tea with Marshmallow Root, you will want to brew it with cold water to preserve the mucilaginous properties.
