Wherein the cassia twig and the monkshood are monarch drugs, and the cassia twig is pungent, sweet and warm, warms and dredges the channels and collaterals, and is good at easing the joints to eliminate wind evil; fu Zi is pungent, sweet and hot, and is the key herb for dredging twelve meridians and purifying yang; the two medicines are used together to expel wind and remove dampness to dredge vessels, warm meridians and dispel cold to strengthen yang. The ephedra herb, the divaricate saposhnikovia root and the largehead atractylodes rhizome are ministerial drugs, the ephedra herb is pungent and slightly bitter in taste and warm, the divaricate saposhnikovia root is pungent and sweet and slightly warm, and the largehead atractylodes rhizome is bitter and sweet and warm, and the three drugs can be used for dispelling wind and cold. The rhizoma anemarrhenae, the peony and the ginger are adjuvant drugs, the rhizoma anemarrhenae clears heat and nourishes yin, the white peony root nourishes blood and nourishes nutrient, and the ginger harmonizes stomach and prevents vomiting. The liquorice is used as a guiding drug to coordinate the effects of the other drugs in the recipe. The formula has the effects of dispelling wind and removing dampness, warming meridians and relieving arthralgia, and nourishing yin and clearing heat, and is named after the particularity of cassia twig, Chinese herbaceous peony and rhizoma anemarrhenae in the formula, so that the cassia twig, Chinese herbaceous peony and rhizoma anemarrhenae decoction is called.
The classical famous prescription is a prescription recorded in ancient Chinese medical record which is widely applied, has definite curative effect and obvious characteristics and advantages. The traditional Chinese medicine decoction is the mainstream of traditional Chinese medicine clinical medication, wherein the classical famous prescription is the crystal of traditional Chinese medicine in clinical practice for thousands of years, has the characteristics of reasonable formula, exact curative effect, high safety and the like, is one of essences of the theory of traditional Chinese medicine, but is inconvenient to decoct and carry, has difficult unified standard, and seriously influences the clinical application of the traditional Chinese medicine, so that the traditional Chinese medicine decoction is simple and easy to use, and has great research and development significance on the standard granules of the classical famous prescription meeting the rhythm of modern life. The clinical curative effect of the classical famous prescription is exact, and the quality of the compound preparation is controlled by using a modern analysis technology, so that the stable quality of the compound preparation is ensured, and the clinical application of the classical famous prescription can be better promoted.
