This article systematically analyzes the historical evolution of the name， medicinal parts， origin， harvesting， processing and other aspects of Houttuyniae Herba（HH） by referring to the medical books， prescription books and other documents of the past dynasties， combined with the research materials related to modern and contemporary times， in order to provide a basis for the development of famous classical formulas containing this herb. In ancient literature， HH was often referred to as "Ji" and "Jicai"， the name of "Ji" was first recorded in Mingyi Bielu during the Han and Wei dynasties， and the name of Yuxingcao was first seen in Lyuchanyan Bencao during the southern Song dynasty and has continued to this day. The origin of HH used throughout history is consistent， all of which are the whole herb or aboveground parts of Houttuynia cordata in Saururaceae family. HH recorded throughout history has a wide range of production areas， mostly self-produced self-marketing. In ancient times， fresh HH was often used as medicine by pounding its juice without involving any processing steps. Both fresh and dried products can be used as medicine， the fresh products uses the whole plant， while the dried products uses the aboveground parts， which are cleaned， selected and processed before use. Fresh products are harvested regardless of season， while dried products are harvested in both summer and autumn， with summer as the best. In ancient times， there were no specific requirements for the quality of HH， while in modern times， "intact stems and leaves with a strong fishy smell" are preferred. In addition， the medicinal properties of HH have undergone significant changes from ancient to modern times. In the early period， it was believed that its medicinal property was slightly warm， until the 1977 edition of Chinese Pharmacopoeia officially changed it to slightly cold. Both ancient and modern literature states that HH can be used for the treatment of carbuncle and malignant sores， Lyuchanyan Bencao for the first time introduced HH fresh juice can relieve summer heat， since Diannan Bencao recorded that it can be used for lung carbuncle， and gradually developed into the first choice for the treatment of lung carbuncle. Based on the research results， it is suggested that fresh herb or dried aboveground parts of H. cordata are used as medicine when developing famous classical formulas.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Forsythia suspensa is a traditional Chinese medicine and a commonly used landscaping plant. Its dried fruit is used in medicine for its functions of clearing heat, removing toxins, reducing swelling, dissipating masses, and dispersing wind and heat. It possesses extremely high medicinal and economic value. However, the genetic differentiation and diversity of its wild populations remain unclear. In this study, chloroplast genome sequences were obtained from 15 wild individuals of F. suspensa using high-throughput sequencing technology. The sequence characteristics and intraspecific variations were analyzed. The results were as follows:(1) The full length of the F. suspensa chloroplast genome ranged from 156 184 to 156 479 bp, comprising a large single-copy region, a small single-copy region, and two inverted repeat regions. The chloroplast genome encoded a total of 132 genes, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes.(2) A total of 166-174 SSR loci, 792 SNV loci, and 63 InDel loci were identified in the F. suspensa chloroplast genome, indicating considerable genetic variation among individuals.(3) Population structure analysis revealed that F. suspensa could be divided into five or six groups. Both the population structure analysis and phylogenetic reconstruction results indicated significant genetic variation within the wild populations of F. suspensa, with no obvious correlation between intraspecific genetic differentiation and geographical distribution. This study provides new insights into the genetic diversity and differentiation within F. suspensa species and offers additional references for the conservation of species diversity and the utilization of germplasm resources in wild F. suspensa.

Amber and subfossil resins are subjects of interdisciplinary research across multiple fields. However, due to their diverse origins and complex compositions, different disciplines vary in their definitions and functional interpretations. In traditional Chinese medicine(TCM), amber has been utilized as a medicinal material since ancient time, with extensive historical documentation. However, its classification, provenance, and nomenclature remain ambiguous, and authentic medicinal amber artifacts are exceedingly rare. This study employed Fourier-transform infrared spectroscopy(FTIR) to characterize amber and subfossil resins from various geological sources and commercially "medicinal amber". Additionally, historical literature and market surveys were analyzed to explore their provenance, composition, and functional attributes. The results indicate that amber and subfossil resins from different sources and with different compositions exhibit distinct fingerprint characteristics in the FTIR spectral range of 1 800-700 cm~(-1). "Medicinal amber" available in the market primarily consists of subfossil or modern resins, significantly differing in composition and structure from geological amber. This study highlights the importance of interdisciplinary research on amber identification and resource management. It is essential to establish a systematic database of amber and subfossil resin characteristics and integrate modern analytical techniques to enhance research on their composition, pharmacological mechanisms, and potential therapeutic effects, thereby promoting the standardized utilization of amber resources and advancing the modernization of TCM.

Qing court records show that Arecae Semen was extensively applied. The royal medical records of the Qing Dynasty document nine types of Arecae Semen, with the Palace Museum preserving seven kinds, totaling twelve cultural relics. Historical documents and physical artifacts corroborate each other, providing evidence for the study of the supply channels and court processing of Arecae Semen in the Qing court. According to relevant Qing court archival records, the sources of Arecae Semen used in the imperial court were diverse, including tributes from foreign countries such as Vietnam and Gurkha, annual tributes from local governments in Guangdong, gifts from close aides, and commodities purchased by the Imperial Household Department from civilian shops. The imperial physicians of the Qing court placed great emphasis on the specifications of Arecae Semen slices and were extremely meticulous about their processing. The variety of Arecae Semen slices used in the Qing palace exceeded those recorded in the botanical texts of the era. Compared with the commonly used processing methods for Arecae Semen in the Qing Dynasty, the imperial physicians adjusted the properties and efficacy of the herbs through different processing techniques, based on the patient's condition, constitution, and other factors, in order to meet the clinical treatment needs of the court. The slicing of Arecae Semen in the Qing court required strict control of thickness, with an average thickness of 0.44 mm, which is significantly thinner than the Arecae Semen slices found in today's markets. The texture was softer, making them easier to chew and absorb. Both the Qing court Arecae Semen slices and the Muxiang Binglang Pills focused on the use of authentic medicinal materials, ensuring the quality of the medicine and enhancing the efficacy of Arecae Semen through meticulous selection and preparation.

Maidong products are categorized into "Hang Maidong" and "Chuan Maidong". Since the Ming and Qing Dynasties, "Hang Maidong" has been regarded as having superior quality, but currently, it remains in name only in the market. This article reviewed historical materia medica and local chronicles from the Ming and Qing Dynasties and analyzed the historical evolution of Maidong production areas. The history of Maidong production in Zhejiang can be traced back to the Song Dynasty, and cultivation had already developed by at least the Ming Dynasty. During the Ming and Qing Dynasties, it was consistently used as a tribute. Ming Dynasty chronicles record "Chuan Maidong", which had already been cultivated on a large scale by the Qing Dynasty. "Hang Maidong" and "Chuan Maidong" share the same origin, with the former identifiable by the "gourd waist" shape of its tuberous root. Based on this, it can be inferred that the "Maimendong" herb illustrated in the Origins of Materia Medica(Ben Cao Yuan Shi) and the Maidong stored in the Qing Palace Imperial Pharmacy were both "Hang Maidong". The protection and development of the authentic "Hang Maidong" medicinal herb are urgently needed.

Sanqi is first recorded in the Compendium of Materia Medica(Ben Cao Gang Mu) in the Ming Dynasty. During the Ming and Qing Dynasties, Sanqi, as a precious Dao-di herb, was successively spread and introduced for cultivation. This study verified the germplasm resources, production areas, and spread of Sanqi in the Ming and Qing Dynasties by systematically reviewing the historical materials, such as materia medica works and local chronicles, and the modern distribution of production areas. In the Ming and Qing Dynasties, the original plants of Sanqi included Panax notoginseng, P. japonicus, P. bipinnatifidus, P. zingiberensis, P. stipuleanatus, and Gynura japonica. Among them, the production area of P. notoginseng has changed. From 1578 to 1593, the main production areas of P. notoginseng were Nandan county, Hechi city in Guangxi Zhuang autonomous region and Guangnan county and Funing county, Wenshan prefecture in Yunnan province. From 1683 to 1755, the production areas of P. notoginseng additionally included Yizhou district, Tian'e county, and Huanjiang county in Hechi city, and Tianyang district and Tiandong county in Baise city, Xincheng county and Gongcheng county in Guangxi Zhuang autonomous region. From 1765 to 1892, the production areas additionally included Youjiang district, Debao county, Napo county, and Jingxi city in Baise city, and Tiandeng county in Guangxi Zhuang autonomous region, and Wenshan city, Malipo county, Yanshan county, Xichou county, and Maguan county in Wenshan prefecture, and Baoshan city, Dali prefecture, Lincang city, Honghe prefecture, Mangshi city, and Lushui city in Yunnan province. During the Wanli period of the Ming Dynasty, Sanqi was introduced to Zhejiang province. During the Qianlong period of the Qing Dynasty, it was introduced to Fujian province. During the Daoguang period of the Qing Dynasty, it was introduced to Hunan province. By comprehensively reviewing the materia medica works, local chronicles, and novel historical materials, this study restores the development history of the Sanqi industry in the Ming and Qing Dynasties. Historical data show that the introduction of Dao-di herbs should consider the biological characteristics of medicinal plants and avoid blind introduction.

Bajitian is a commonly used Chinese medicinal material with a long history of medicinal use, and there is controversy over the authentication of its origins. This article combined historical herbal works with local chronicle records to authenticate the origins of Bajitian used in different regions, analyzed the local chronicle records, and illustrated the evolution of the origins of Bajitian in different regions. The results indicate that Illustrated Classic of Materia Medica first included Guizhou Bajitian and Chuzhou Bajitian. By integrating images and texts and local medicinal practices of Bajitian in the Guizhou and Chouzhou regions in ancient and modern times, it was inferred that the original plant of Guizhou Bajitian was likely to be Damnacanthus officinarum or D. giganteus, while the origin of Chuzhou Bajitian remained unclear. The medicinal history of Sichuan Bajitian was first recorded in the Supplementary Records of Famous Physicians during the Northern and Southern Dynasties. Based on the inference from herbal documents and local chronicle records, it was inferred that the original plant of Sichuan Bajitian may be Schisandra propinqua subsp. sinensis and so on. Guangdong Bajitian is an emerging variety in modern times, and it could date back to the Xingning County Annals in the 20th year during the Kangxi period of the Qing Dynasty(1681). The original plant of Guangdong Bajitian is Morinda officinalis, and Guangdong province became the true producing area of Bajitian in the late Qing Dynasty. This article clarified the origins of Bajitian in different regions by sorting out historical herbal documents and local chronicle records, providing a basis for the authentication of Bajitian in the field of herbology.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.
