Synopsis

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

Luo Han Guo (Siraitia grosvenorii, also known as monk fruit) has a long history of use in Traditional Chinese Medicine (TCM) for supporting the throat and relieving symptoms such as sore throat and cough. In Chinese herbal medicine, Luo Han Guo is classified as a "cooling" herb and is often included in remedies designed to "clear heat" and soothe irritation in the respiratory tract. Traditional texts and modern herbal compendia frequently recommend Luo Han Guo for sore throat, hoarseness, and dry cough, typically prepared as a tea or decoction.

Scientific evidence for its effectiveness in treating sore throats is limited. Some laboratory studies have identified antioxidant and anti-inflammatory properties in Luo Han Guo extracts, which could theoretically contribute to its soothing effects. However, clinical trials specifically investigating its efficacy for sore throat relief are lacking. The use for this purpose is therefore primarily justified by longstanding tradition and anecdotal use rather than robust scientific validation. The evidence rating is moderate based on traditional use (2 out of 5), reflecting the absence of high-quality clinical studies but a strong historical precedent for its application in this context.
