Sichuan Lovage (Ligusticum chuanxiong), known as Chuanxiong in Traditional Chinese Medicine (TCM), is primarily used for enhancing blood circulation, dispelling wind, and alleviating pain, particularly headaches and menstrual discomfort. In the context of fibromyalgia syndrome, its use is largely based on traditional practices rather than robust scientific evidence. TCM practitioners may prescribe Chuanxiong in herbal formulas for fibromyalgia patients, interpreting the syndrome’s symptoms as manifestations of blood stasis or Qi stagnation, which Chuanxiong is believed to address by promoting the flow of blood and Qi.

However, there is only minimal scientific research evaluating the efficacy of Sichuan Lovage for fibromyalgia specifically. Most modern studies focus on its effects in cardiovascular health, pain relief in other conditions, or neuroprotection, but not directly on fibromyalgia. Clinical trials or systematic reviews supporting its use for fibromyalgia are lacking, and any effect is extrapolated from its traditional use for generalized pain or neurological symptoms.

In summary, the use of Sichuan Lovage to support or treat fibromyalgia is justified by traditional use rather than scientific validation, and the overall evidence supporting its effectiveness for this specific condition is very limited.
