Synopsis

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

Manzanita (Arctostaphylos spp.) has a history of traditional use by various Native American tribes in North America for treating sore throats and other minor respiratory ailments. The leaves and sometimes berries were prepared as teas, gargles, or infusions to soothe throat irritation and minor inflammation. The justification for its use is primarily based on this ethnobotanical tradition rather than rigorous modern scientific validation.

While manzanita contains compounds such as arbutin and tannins, which have mild astringent and antimicrobial properties, there is little direct clinical evidence to support its efficacy specifically for sore throat in humans. Most of the available information is anecdotal or derived from historical records. Some laboratory studies on related species suggest potential antibacterial activity, but these findings have not been substantiated in controlled human trials for sore throat relief.

In summary, manzanita’s use for sore throat is rooted in traditional practices, particularly among indigenous peoples of western North America. The scientific evidence supporting its effectiveness for this specific condition is limited and largely indirect, resulting in a low evidence rating.
