Asarum heterotropoides, commonly known as wild ginger or "xi xin" in Traditional Chinese Medicine (TCM), has a long history of use in supporting the sinus and respiratory systems. In TCM, it is often prescribed to "dispel wind-cold," relieve nasal congestion, and alleviate headaches associated with sinus issues. Classical texts, such as the Shennong Bencao Jing, mention its application in formulas like "Xixin Tang" and "Cang Er Zi San," which are traditionally used to treat rhinitis, sinusitis, and related symptoms. The aromatic and pungent properties of Asarum heterotropoides are believed to help open nasal passages and promote drainage.

However, while there is substantial traditional backing for its use in sinus support, modern scientific validation remains limited. Some laboratory studies have identified anti-inflammatory and mild analgesic compounds in the plant, but rigorous clinical trials specifically assessing its efficacy for sinus health are lacking. Moreover, Asarum species contain aristolochic acids, which are potentially nephrotoxic and carcinogenic, raising serious safety concerns. Therefore, while its use is justified by tradition and supported by historical practices, scientific evidence is insufficient to strongly validate its effectiveness or safety for the sinus body system.
