Ligustrazin (also known as tetramethylpyrazine, derived from the Chinese herb Ligusticum chuanxiong) is primarily used in Traditional Chinese Medicine (TCM) for conditions related to blood circulation, such as headaches, chest pain, and cardiovascular diseases. Its use for sinus congestion (nasal or sinus congestion) is rooted in traditional practice rather than scientific validation. In TCM, Ligustrazin-containing herbs are sometimes included in formulas intended to "dispel wind and relieve pain," which may encompass symptoms like headache or nasal congestion, particularly those attributed to blood stasis or poor circulation.

However, direct scientific evidence supporting Ligustrazin for the treatment of sinus congestion is minimal. Most pharmacological studies of Ligustrazin focus on its effects on the cardiovascular and nervous systems, including anti-inflammatory, neuroprotective, and vasodilatory actions. These properties could theoretically have some relevance to sinus congestion if it is related to vascular or inflammatory processes, but no robust clinical trials or systematic reviews support its efficacy for this indication. Therefore, the use of Ligustrazin for sinus congestion is justified primarily by traditional use, with very limited scientific evidence backing this application.
