Forsythia (Forsythia suspensa) is primarily used in traditional Chinese medicine (TCM) and is well known as part of the classic formula "Yin Qiao San," which is administered at the early stages of febrile diseases, especially when symptoms like chills and fever first appear. In TCM theory, forsythia is thought to "clear heat" and "remove toxicity," but it is also used at the onset of external wind-heat invasion, which can manifest with chills and fever. The use of forsythia for chills is thus rooted in traditional practices rather than modern biomedical research.

There is limited scientific research directly supporting the use of forsythia for chills specifically. Most modern studies focus on its anti-inflammatory, antimicrobial, and antioxidant properties, which may indirectly relate to its traditional use for infections that can cause chills. However, these studies do not specifically address its efficacy for chills as a symptom. Therefore, the evidence for forsythia’s use for chills is largely traditional, with some weak supportive evidence from its general effects on immune modulation and infection reduction, but not directly studied or validated in clinical trials for chills as an isolated symptom.

In summary, the use of forsythia for chills is justified by tradition in Chinese herbal medicine, with very limited scientific evidence to support or refute its effectiveness for this specific symptom.
