Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Marshmallow (Althaea officinalis) root has a long history of traditional use for soothing sore throats and other mucous membrane irritations. Ancient Egyptians, Greeks, and Romans documented the use of marshmallow preparations for throat and respiratory complaints. The plant contains mucilage, a gelatinous substance that coats and soothes irritated tissues. This mucilage is believed to form a protective layer over the mucous membranes of the throat, thereby relieving discomfort associated with soreness or inflammation.

While the traditional use is well established, scientific evidence supporting marshmallow's efficacy for sore throat is limited and primarily based on in vitro studies or small clinical trials. Some laboratory studies suggest that marshmallow extract can reduce irritation and may have mild anti-inflammatory effects. However, robust, large-scale clinical trials in humans are lacking. The existing evidence is promising but not definitive.

Overall, marshmallow's use for sore throat is justified by centuries of traditional use, supported by its known mucilaginous properties, but the scientific validation is still modest. It is generally considered safe when used appropriately, but those with allergies or on certain medications should consult a healthcare provider before use.
