There is no “best match” for Chuanxiong, as it can be combined with different medicines for different diseases, such as Wu Yao (乌药), Angelica sinensis (当归), and so on. Rhizoma Chuanxiong has the ability to move qi and blood (to promote the flow of qi and blood), relieve pain and dispel wind, and can be combined with a variety of medicines to improve different diseases. For example, when combined with Wu Yao, which enters the liver and kidneys at the lower level and the spleen and lungs at the upper level, and is good at moving qi, dispersing cold and relieving pain (relieving pain by removing cold from the body), the two herbs are effective in treating dysmenorrhea, amenorrhea and menstrual irregularities caused by stagnation of qi and stagnation of blood (stagnation of blood due to lack of circulation of qi). Chuanxiong can also be combined with Angelica sinensis, which is moist and favors nourishing and invigorating the blood. Combined, the two herbs can remove blood stasis without harming the qi and blood, and nourish the blood without leading to congestion and stagnation of qi, which is effective for dysmenorrhea and amenorrhea caused by blood deficiency and stasis of blood, headache, irregular menstruation, and abdominal pain caused by blood stasis after giving birth. It should be noted that Rhizoma Chuanxiong should not be used in pregnant women, patients with headache caused by hyperactivity of liver yang (excessive liver yang causing dizziness, dizziness, headache, etc.), or patients suffering from yin deficiency (deficiency of yin and essence in the body, resulting in hyperactivity of deficiency fire). Excessive use of Rhizoma Chuanxiong may cause nausea, vomiting, chest tightness and other toxic reactions, therefore, if there is a need for the use of the drug, it must be under the guidance of a professional Chinese medicine practitioner.
