Rating (out of 5): 1

Japanese Honeysuckle (Lonicera japonica) has a long history of use in traditional Chinese medicine (TCM), where it is known as "Jin Yin Hua." In TCM, it is primarily used for its purported abilities to "clear heat" and "relieve toxicity," and is most commonly recommended for conditions such as fever, sore throat, and certain types of infections. There are some traditional applications for respiratory symptoms, including cough and sore throat, which occasionally extend to discomfort or pain in the chest, especially when interpreted as being due to "heat toxins" or inflammatory processes in the lungs. However, the use of Japanese Honeysuckle specifically for chest pain (angina or non-infectious chest pain) is not well-documented in classical herbals or modern TCM literature. Its traditional use for chest pain, if any, is indirect and generally linked to its anti-inflammatory and antimicrobial properties rather than a direct analgesic effect on chest pain itself.

From a scientific perspective, studies have identified anti-inflammatory, antioxidant, and immunomodulatory effects of Japanese Honeysuckle extracts, but there is no robust clinical evidence supporting its use for chest pain—particularly not for cardiac or non-infectious causes. Therefore, while its use for chest pain is rooted in tradition and some broad respiratory indications, strong scientific validation is lacking. The evidence level is low, and it should not replace established treatments for chest pain of cardiac or other serious origin.
