Sichuan Lovage (Ligusticum chuanxiong), known as Chuanxiong in Traditional Chinese Medicine (TCM), is primarily used for its ability to invigorate blood, promote the movement of Qi, and alleviate pain. Its traditional uses are most strongly associated with cardiovascular, neurological, and gynecological conditions—such as headaches, menstrual disorders, and chest pain—rather than with direct treatment of lung congestion. However, in the context of some TCM formulations, Sichuan Lovage may be included as a minor ingredient to support circulation and help resolve patterns that TCM conceptualizes as "wind-cold" or "phlegm" obstructing the meridians, which can sometimes present with respiratory symptoms, including mild congestion. There is limited traditional evidence supporting its use specifically for lung congestion, and its role is generally adjunctive rather than primary. Modern scientific evidence for its effectiveness in treating lung congestion is lacking, and there are no robust clinical trials demonstrating efficacy for this indication. Most scientific research has focused on its anti-inflammatory and vasodilatory effects, especially in cardiovascular and neurological contexts, rather than respiratory health. In summary, while there is a minor, indirect rationale in TCM tradition for its inclusion in formulas for certain types of congestion, scientific validation for this specific use is minimal.
