Ligusticum wallichii, known as Chuanxiong in Traditional Chinese Medicine (TCM), has a long history of use for a variety of conditions, including congestion. The term "congestion" in TCM often refers to stasis or stagnation of blood and Qi (vital energy), sometimes manifesting as headaches, chest pain, or nasal congestion. Chuanxiong is traditionally used to "invigorate blood," "promote the movement of Qi," and "expel wind," which are believed to help relieve various forms of congestion, especially those related to the upper respiratory tract and sinuses. Historical texts and TCM formularies frequently include Ligusticum wallichii as a key component in herbal formulas aimed at treating headaches, sinus congestion, and menstrual disorders due to its blood-moving properties.

From a scientific perspective, some pharmacological studies suggest that Ligusticum wallichii contains active compounds such as ligustilide, which exhibit anti-inflammatory and vasodilatory effects. These properties might theoretically alleviate symptoms of congestion by reducing inflammation and promoting better blood flow. However, direct clinical evidence specifically supporting its use for respiratory or nasal congestion is limited, and most studies focus on cardiovascular or neuroprotective effects. Thus, while traditional use is well-documented, scientific validation remains modest and mostly indirect.
