ABSTRACT
Textual research on Chinese herbs is the preliminary work for the preparation of famous classical prescriptions. Through literature review，it was found that the researches of Persicae Semen focused on chemical compositions，pharmacological mechanism and medical record analysis in the recent years，and few researches based on the ancient literature were about the origin，concocting methods，flavor，meridian tropism，effects and indications. Textual research shows that the most commonly used names are Taoren and Taoheren，with a wide range of producing areas. The plant origin of Persicae Semen has not changed much since ancient times. Before the Qing dynasty，the plant origin of Persicae Semen was from the seeds of a kind of fruit named Shantao or Maotao，and in modern times，the seeds of Amygdalus persica or A. davidiana have become the major source. While different books have different views on Latin names for the origin of the Persicae Semen. We suggest that the Latin names of A. persica and A. davidiana should be more reasonable for Tao and Shantao respectively .In the concocting methods of Persicae Semen for activating vital energy and blood circulation，raw Persicae Semen should be used with peel and tip，while for moisturizing dryness，it should be fried into yellow without peel. Therefore，in the concocting methods of Persicae Semen for Taohe Chengqitang and Taohong Siwutang，the raw materials should be fried into yellow without peel or tip，while for Shentong Zhuyutang，raw Persicae Semen materials should be used with peel and tip. The indications of Persicae Semen include amenorrhea，lump，parasite，obstruction of chest，cough and asthma，constipation，etc.，and the people with blood deficiency，blood dryness and the pregnant women should use it with caution or should not use it. The modern clinical application of Persicae Semen is only a partial inheritance of ancient literature，which means that the Persicae Semen still has many effects to be verified and studied，and it is worthwhile for further exploration in order to expand its clinical application. The records of ancient literature on flavor，meridian tropism，and quality evaluation of Persicae Semen were consistent with those in Chinese Pharmacopoeia. Because of the similar appearance，it is especially difficult to distinguish Persicae Semen and Armeniacae Semenis Amarum after crushing ，requiring much time and money for identification. It is recommended that medical institutions should purchase Persicae Semen without crushing as far as possible，then decide the best concocting methods according to the clinical requirement.
ABSTRACT
The research and development of classical famous prescriptions is an important way to actively promote the development of traditional Chinese medicine.It is particularly important to sort out the historical evolution of the composition of traditional famous prescriptions to make clear the origin，producing areas and concocting methods of traditional Chinese medicine，which is the source of ensuring the safety and efficacy.Through literature review，it is found that at present，the research of mulberry white skin focuses on chemical composition，pharmacological mechanism and modern clinical research，and there are few ancient literature studies.Therefore，based on the ancient literature，the author conducts a comprehensive textual research on mulberry bark from its name，origin，producing areas and concocting methods and other aspects，in order to provide literature reference for the research and development of the prescription involving mulberry bark in the classic prescription.Through research，we can know that there are more than 20 aliases of mulberry bark，and the most commonly used names in modern times are "sangbaipi""sanggenbaipi""sangpi"，etc.In Tang and Song dynasties and before，mulberry bark was mainly composed of Morus alba var. alba and jisang，after Tang and Song dynasties，mulberry bark plant sources showed diversity，in modern times，Morus alba var. alba was gradually identified as the main medicinal species of mulberry bark.Therefore，it is suggested that Morus alba var. alba be selected as the plant source of mulberry bark.According to ancient books，mulberry trees are cultivated everywhere，with Jiangsu，Zhejiang and Sichuan as the best areas，and Henan and Anhui as the most popular areas in modern times.The conclusion of ancient and modern quality of mulberry bark is basically the same，the root skin is white，thick and sweet.The morden concocting methods of mulberry bark mainly include raw mulberry bark，honey mulberry bark and fried mulberry bark.According to the textual research of ancient literature，in addition to the above three kinds of medical specifications，there have been concocting methods without auxiliary materials，such as burning，baking and roasting，as well as concocting methods with auxiliary materials，such as bran roasting，rice swill soaking，honey wine roasting，etc.The concocting methods of mulberry bark used by the classical famous recipe should be selected in combination with specific drug provisions.
