Synopsis
Source of validity: Traditional
Rating (out of 5): 3
Mucilage refers to a group of naturally occurring, gel-like polysaccharides found in various plants such as marshmallow root (Althaea officinalis), slippery elm (Ulmus rubra), and plantain (Plantago spp.). The use of mucilage-containing herbs to soothe dry coughs has a long history in traditional medicine, particularly in European and Native American herbal practice. Mucilages are believed to provide a protective, soothing layer over mucous membranes in the throat and respiratory tract, thereby reducing irritation and suppressing the cough reflex associated with dryness. While there is a solid traditional basis for their use, modern scientific evidence is limited. Some in vitro and animal studies suggest that mucilage can form protective films, and a few small human studies and case reports support their demulcent (soothing) effect in the mouth and throat. However, there is a lack of large, high-quality clinical trials specifically evaluating their effectiveness in treating dry cough in humans. Major pharmacopoeias and herbal monographs (such as those from the European Medicines Agency and the German Commission E) recognize mucilage-containing herbs as traditional remedies for dry, irritating coughs, but consistently note the limited clinical data. In summary, the use of mucilage for dry cough is primarily justified by tradition, with moderate but not robust supporting evidence.
