Quotes from Chinese historical sources:
THE HERBAL CLASSIC OF SHEN-NONG: "Useful against headache due to the invasion of pathogenic wind into the brain, arthralgia due to cold, clonic spasms of muscles, wounds due to sharp objects and sterility due to amenorrhea."
THE COMPENDIUM OF MATERIA MEDICA: "Chuanxiong is an herb for vital energy in the blood, and is applicable to syndromes of qi stagnation because it is so pungent in taste as to be dispersing. In the book 'Zuo's Historical Records of the Spring and Autumn Period' (770 - 476 BC) it is referred to as maiju and used to treat abdominal ailments caused by freshwater fish. For quick effects in the treatment of diarrhea, it is always used with two other ingredients. In cases of pain after recovery from dysentery with bloody stools resulting from loss of yin and stagnation of qi, the addition of chuanxiong to the recipe as an adjuvant will activate the flow of qi and regulate the circulation of the blood to provide prompt relief."
OPINIONS ON THE PROPERTIES OF HERBS:"Chuanxiong is an herb for qi in the blood, which can regulate menstruation in the lower part of the body and resolve stagnation in the middle part, with its potency going upward to the head and eyes. It has been used as a conductant for Chinese angelica, which is not only effective in treating blood troubles, but also excellent for the treatment of qi disorders. Pungent in taste, positive in nature, quite migratory in property and lacking any stagnation or viscosity, it can dispel all types of pathogenic wind and regulate the flow of all types of qi."
