RESUMO
Mulberry leaf was first recorded in the Shennong Bencao Jing(The Classic of Herbal Medicine)ãã on the list of drugs affixed, and first separate recorded in the Bencao Shiyi(Supplement to Materia Medica)ãã. By checking Chinese herbs' literature of the harvest processing and application of mulberry leaves, we found that Mulberry leaves can be harvested in Summer and autumn before the Qing dynasty, but from Qing dynasty to present, those harvested in autumn and winter, which were called frost mulberry leaves or winter mulberry leaves, were seen as better. Before the Republic of China, mulberry leaves were dried in shade or on the fire, after that, they were dried in the sun. It can be found that the harvest processing of mulberry leaves was changing as time went on. The clinical application of mulberry leaves had multiplicity, depending on different picking time and different processing method. It is suggested that research of mulberry leaves on chemistry and pharmacology of picking time, processing method can result in new scientifically clinical application.

By sorting out the literature on materiamedica, it is found that medicinal history of ClinopodiumHerba is rather long which can be traced back to caoxuejiein Lüchan yan ben cao (Mountainous Materia Medica) with definite efficacy and usage; it is generally believed that the original plant of ClinopodiumHerba is Clinopodiumpolycephalum (Vaniot) C. Y. Wu et Hsuan and C. chinensis (Benth.) O. Kuntze are two separate species, also some scholarsclaim that C. polycephalum and C. chinensisare the same plant. But I think C. polycephalum is the main origin of ClinopodiumHerba, and the relationship of C. polycephalum and C. chinensis maybe a species and its variety.

Herba Schizonepetae was firstly recorded in the Sheng nong ben caojing (Shennong's Materia Medica) with the title Jiasu. It could be sure that the original plant of Jiasu is Ocimumbasilicum L. ofLabiatae based on the record of Jiasu's name, morphology, edible property before the Song Dynasty. Beginning from the Ben cao tu jing (Illustrated Classic of Materia Medica) in the Song Dynasty, the source of this drug evolved as SchizonepetatenuisfoliaBriq. ofLabiatae, and it has been in use until now. Hence, the sources of Jiasu should be both O. basilicum L. and the co-existence of S. tenuisfolia Briq in the Qing Dynasty. It is claimed that the hometowns of those herb writers who considered the source ofOcimumbasilicum L. to be the producing areas of cultivation of the edible Ocimumbasilicum L. It was found that the source of Jiasu recorded in the Sheng nong ben cao jing should be O. basilicum L. , hence, it is suggested the title Jiasu should be recorded for the source of O. basilicum L, and the original plant of Herba Schizonepetae was Schizonepetatenuisfolia Briq. of Labiatae, and this medicine should be separately recorded. In fact, Jiasu and Herba Schizonepetae were two different kinds of medicines.

The content of arsenic in sulfur before and after processing was determined. The result shows that the content in raw materials is 8-15 times higher than that of the processed product, which implies that the toxicity of sulfur is obviously reduced by processing.

On experimental gastric ulcer models induced by 0.6mol/L HCl, ethyl alcohol or ligation of the pylorus, the preventive effects of unprepared oyster shell, calcined oyster shell 1(900 degrees C, 1h), calcined oyster shell 2(350 degrees C, 8h) were compared in Wistar rats. Results showed that antagonistic effects of calcined oyster shell 1 to the drug pathogenesis of peptic ulcer and the incidence of peptic ulcer after ligation of the pylorus were markedly greater.
