Rating (out of 5): 2

Marshmallow root (Althaea officinalis) has a long history of use in traditional herbal medicine for soothing irritated mucous membranes, including the throat and tonsils. The mucilage content in marshmallow root is believed to coat and soothe inflamed tissues, which is why it has been used in folk remedies for sore throats, coughs, and tonsillitis. Historical herbal texts and practices in both Western and Eastern herbal traditions cite marshmallow as a demulcent—an agent that relieves irritation of the mucous membranes by forming a protective film.

However, while its traditional use for tonsil and throat discomfort is well documented, scientific research specifically targeting marshmallow’s effects on the tonsils or tonsillitis is limited. Available studies focus more broadly on marshmallow's demulcent properties and its ability to relieve cough and throat irritation, rather than on the tonsils specifically. The few clinical studies available suggest a potential benefit in soothing sore throats, but rigorous, high-quality trials are lacking. Thus, its use is primarily justified by tradition, with modest evidence supporting its soothing effects on upper respiratory tract irritation.

In summary, marshmallow is traditionally used to support throat health, including the tonsils, but robust scientific validation for this specific indication is limited. Its reputation rests mostly on historical and anecdotal use rather than strong clinical evidence.
