ABSTRACT

Wuzhuyu Tang （WZYT）， a classical traditional Chinese medicine （TCM） formula， was first recorded in Treatise on Cold Damage by the prestigious physician ZHANG Zhong-jing in the Eastern Han Dynasty， and included in Catalogue of Ancient Classical Formulas （First Batch）. WZYT is composed of four medcinals： Euodiae Fructus， Ginseng Radix et Rhizoma， Zingiberis Rhizoma Recens， and Jujubae Fructus， which has the effects of warming the middle and tonifying deficiency， dissipating cold and descending adverse qi. Based on data mining， this paper analyzes the modern clinical research literature on WZYT， which is expected to lay a basis for clarifying the "disease-symptom-prescription-medicinal" relationship of WZYT， as well as its modern clinical indications and clinical dosage. With the search term "Wuzhuyu Tang"， 253 complete medical records were retrieved from CNKI， VIP， and Wanfang （2000-2020）， involving 292 TCM prescriptions. Microsoft Excel 2019 was employed to establish the medical record database and the main clinical indications were statistically analyzed. Moreover， the syndromes， incidence law， and medication regularity were summed up. The result indicates WZYT has a wide range of modern clinical applications， mainly including the treatment of headache， dizziness， vomiting， diarrhea， dysmenorrhea， morning sickness， and other diseases， and the "deficiency， cold， and reversal" symptoms， mainly manifested as nausea and vomiting， headache， fatigue and lack of strength， reversal cold of hands and feet， poor appetite， gloomy complexion， dizziness， aversion to wind and cold， abdominal pain， sloppy diarrhea， abdominal distension， poor sleep， pale tongue， white coating， and deep thread wiry pulse. These diseases and symptoms mainly occur in women and middle-aged people. In most cases， medicinals are added or subtracted according to the symptoms， and the common doses of Euodiae Fructus， Zingiberis Rhizoma Recens， Codonopsis Radix or Ginseng Radix et Rhizoma， and Jujubae Fructus in the original prescription are 6-15 g， 10-15 g， 10-15 g or 9-12 g， and 4-6， respectively. The added medicinals are in the descending order of Pinelliae Rhizoma， Atractylodis Macrocephalae Rhizoma， Poria， Glycyrrhize Radix et Rhizoma， and Chuanxiong Rhizoma according to the frequency.
