Textual research on Bambusae Concretio Silicea / 中国中药杂志

By studying various ancient texts such as herbal classics and medical literature from different eras, it was found that there were discrepancies in the records about Bambusae Concretio Silicea(Tian Zhu Huang). In order to establish an accurate foundation, this research was based on ancient herbal literature and combined with plant morphology and investigative studies to examine its earliest mentions in ancient texts, nomenclature, medicinal properties, indications, and quality assessment standards. In the early records, Bambusae Concretio Silicea was referred to by several different names, such as "Zhu Huang" "Tian Zhu Huang" "Zhu Gao" "Zhu Tang", and "Zhu Huang". The earliest known formal usage of the name "Tian Zhu Huang" was found in the book Ri Hua-zi's Materia Medica(Ri Hua Zi Ben Cao). Throughout various ancient texts, the earliest recorded information about Bambusae Concretio Silicea also appeared in Ri Hua-zi's Materia Medica, not in Materia Medica of Sichuan(Shu Ben Cao) or other ancient texts. Ri Hua-zi's Materia Medica provided relevant descriptions of its origin, medicinal properties, and indications, albeit with some errors due to limited knowledge. However, this has been a valuable starting point for future research on Bambusae Concretio Silicea and holds pioneering significance in forming a mature system. As the research delved deeper, the medicinal properties of Bambusae Concretio Silicea have been consistent since Ri Hua-zi's Materia Medica, and the understanding has gradually improved through years of clinical verification. During the investigation process, the authors found limited records on the quality evaluation of Bambusae Concretio Silicea in ancient texts. Although the information is scarce, it serves as a foundational basis for establishing corresponding quality grading standards for Bambusae Concretio Silicea in the future.

Textual Research on Trionycis Carapax / 中国实验方剂学杂志

Trionycis Carapax is a commonly used Chinese medicine in clinical practice. Modern research on Trionycis Carapax mainly focuses on experimental research and clinical observation， which has been rarely reported in the literature. Based on the literature on medicinal herbs， medical books， prescriptions of all dynasties， this study carried out systematic textual research on the historical evolution and changes of the name， origin， producing areas， quality， efficacy， indications， processing methods， and contraindications of the Trionycis Carapax. As revealed by the textual analysis， the origin of Trionycis Carapax is Trionyx sinensis， and the carapace of T. steindachneri is not suitable for the preparation of Trionycis Carapax. The genuine producing areas of Trionycis Carapax include Yueyang， Jingzhou， southeast Anhui， and western Jiangsu in the middle and lower reaches of the Yangtze river. Regarding the quality， the number of ribs of Trionycis Carapax， such as seven ribs and nine ribs， is often used as the quality evaluation standard in ancient Chinese herbal books. However， through literature research and field inspections on the medicinal material markets， it is not advisable to take rib number as a quality evaluation criterion in modern times. With the change of the times， the efficacy and indications of Trionycis Carapax have gradually expanded on the basis of Shennong’s Classic of Materia Medica （Shen Nong Ben Cao Jing）， and later generations widely apply it in internal medicine， surgery， gynecology， pediatrics， etc. It should be noted that the treatment of labor heat and bone steaming by Trionycis Carapax is derived from Shennong’s Classic of Materia Medica， not Treatise on the Nature of Medicinal Herbs （Yao Xing Lun） mentioned in ancient books such as Amplification on Materia Medica （Ben Cao Yan Yi）. The processing methods of Trionycis Carapax are diverse， which are dominated by traditional vinegar processing. In terms of contraindications， Trionycis Carapax should not be compatible with bauxite and marble and is contraindicated in pregnant women. Those with spleen deficiency， weak stomach， and liver deficiency without heat should use it with caution. This study is expected to provide the basis for radical reform and further development and clinical utilization of Trionycis Carapax.

Literature Analysis and Textual Research on Huaihuasan / 中国实验方剂学杂志

Huaihuasan， first recorded in Puji Benshifang by XU Shu-wei from the Southern Song dynasty， consists of four herbs， namely Sophorae Flos （fried）， Platycladi Cacumen （smashed with pestle and baked）， Schizonepetae Spica， and Aurantii Fructus （cut into pieces after the removal of pulp and then fried yellow with wheat bran）. At present， Huaihuasan and its modified formulas vary in clinical usages and dosages， and the resulting outcomes have been investigated. However， there are few reviews uncovering its historical evolution. On this basis， this review systematically combed and verified the historical evolution， dose conversion between ancient and modern times， efficacy， and indications of Huaihuasan， as well as the origin and processing of the contained herbs. The findings have demonstrated that Huaihuasan is composed of four herbs， with the original plants and medicinal parts basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia. Sophorae Flos refers to the dried flower and bud of Sophora japonica in family Leguminosae， Platycladi Cacumen the dried branch and leaf of Platycladus orientalis in family Cupressaceae， Schizonepetae Spica the dried flower spike of Schizonepeta tenuifolia in family Labiatae， and Aurantii Fructus the dried immature fruit of Citrus aurantium in family Rutaceae or its cultivated varieties. On account of the efficacy in clearing intestine， stopping bleeding， dispersing wind， and moving Qi， Huaihuasan has been mainly used to treat intestinal diseases such as bloody defecation and perianal abscess. In modern clinical practice， it is mainly applicable to patients with hematochezia and bleeding due to internal hemorrhoid， ulcerative colitis， or anal fissure. It was suggested that the raw medicinal materials should be decocted and processed according to the methods described in the 2020 edition of Chinese Pharmacopoeia. Following the conversion formula of one Qian=4 g， this paper determined the dosages of Sophorae Flos （fried）， Platycladi Cacumen （smashed with pestle and baked）， Schizonepetae Spica， and Aurantii Fructus （cut into pieces after the removal of pulp and then fried yellow with wheat bran） all to be 2 g， with the total dosage being 8 g. Such comprehensive analysis based on ancient books and modern literature has provided a more scientific reference for the clinical application， research， and development of this classical formula.
