Synopsis

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

Lysimachia clethroides, commonly known as gooseneck loosestrife or "bai qian" (白前) in traditional Chinese medicine (TCM), has been used historically for sore throat and related ailments. In TCM, it is often included in herbal mixtures to 'clear heat' and 'reduce toxicity,' which are believed to underlie conditions like sore throat and pharyngitis. Several classical texts and regional herbal compendia mention its use for treating symptoms such as throat inflammation, cough, and upper respiratory complaints.

However, there is limited modern scientific research specifically validating its efficacy for sore throat. The few available laboratory or pharmacological studies focus on its general anti-inflammatory or antimicrobial properties, but direct clinical trials or robust human evidence for sore throat relief are lacking. Thus, while its use is well-rooted in traditional practice with anecdotal and historic support, the evidence base from a scientific perspective remains weak. The rating of 2 reflects strong traditional support but insufficient modern validation.
