RESUMEN
Tibetan medicine Bang Jian refers to a range of botanical drugs within the Gentiana genus. It serves as a prominent traditional Tibetan botanical drug primarily found in the ethnic minority regions of the Qinghai-Tibet Plateau in China. Traditionally, the dried flowers of Bang Jian, known as "Longdanhua" have been employed in Tibetan medicine to address detoxification, pharyngeal relief, acute and chronic bronchitis, bronchiectasis, lung infections, pulmonary fibrosis, and throat disorders. Surprisingly, there has been no comprehensive review published to date on Tibetan medicine Bang Jian. This passage systematically presents and critically assesses recent advancements in botanical characterization, traditional applications, phytochemistry, pharmacology, and clinical uses of Bang Jian, aiming to provide a scientific foundation for its reasonable use and further exploration. To date, researchers have isolated and identified 92 structurally diverse compounds, with a predominant presence of iridoids, flavonoids, xanthones, and triterpenoids. The crude extracts and metabolites derived from Bang Jian have been found to exhibit a wide range of pharmacological effects, encompassing anti-inflammatory, anti-tumor, anti-bacterial, antiviral, antioxidant, hepatoprotective properties, and protect the respiratory system. Nevertheless, detailed data on the biological effects, metabolic activities, and mechanistic research concerning active monomer metabolites remain insufficient. Consequently, there is a pressing need for comprehensive and in-depth research to guide rational clinical drug usage and evaluate the medicinal attributes of Bang Jian.
RESUMEN
Zha-xun is widely used in Tibetan medicine and is also an international traditional medicine. This study believes that the black organic matter constituting Zha-xun is mainly stored in the rocks. The exudation points of Zha-xun mostly distribute on the cliffs of high mountains, which makes it difficult to evaluate its resource distribution and storage area. This paper was aimed at the exudation environment of Tibetan medicine Zha-xun in Sichuan province and 6 ecological environmental factors of the Zha-xun were determined via the field investigation. Combining with these 6 factors as well as the GIS data of Sichuan province, ArcGIS software was used to extract ideal environmental factors which are suitable for exudation of Zha-xun, including geology types, geomorphological types, altitude, slope, vegetation types, and mean annual temperature. The spatial overlay analyses on the extracted environmental factors were carried out to predict the distribution area of Zha-xun in Sichuan province. Afterwards, field investigation was conducted to verify the prediction. The prediction showed that the exudation spots of Zha-xun in Sichuan province mainly located in 29 counties including 12 in Aba Prefecture, 15 in Ganzi Prefecture, and Muli County and Dechang County in Liangshan Prefecture. The deposit areas of Zha-xun were located in the Triassic, Devonian and Silurian strata and were basically distributed in 9 basins, including Dingqu River, Yalong River, Xianshui River, Dadu River, Suomo River, Minjiang River and Baishui River, characterized by a fragmented patch-like distribution along the mountain ranges, and the exudation spots of Zha-xun were mainly scattered among the rain-free cliffs' concavities of river valleys at a certain altitude. The prediction was consistent with the field investigation results, which suggested that it is possible and feasible to predict distribution of Zha-xun resources based on GIS-analysis. The study may provide a scientific basis for comprehensive investigations into Zha-xun's distribution and formation mechanism, thus promoting rational development and utilization of Zha-xun resources.

BACKGROUND: Tibetan medicine (TM) and traditional Chinese medicine (TCM) are two independent traditional medical systems. Due to geographical factors, the development of Tibetan medicinal theory is relatively independent, but there are still many shared-use medicines in TM and TCM. However, a thorough and comparative study on those medicines is still absent. This study listed shared-use medicines by TM and TCM and analyzed the similarities and dissimilarities of these two medical systems. This paper also aimed to understand mutual influences like the shared history of TM and TCM and to roughly outline the exchanging process between them. METHODS: Shared-use medicines in TM and TCM were listed alphabetically. Information on the scientific name, material name, medicinal parts, and medical efficacy were extracted from publications. Shared-use medicines were grouped according to medicinal properties and medicinal parts used by TM and TCM. The historical origin and current status of clinical prescriptions of shared-use medicines were analyzed. RESULTS: A total of 136 shared-use medicines in TM and TCM were listed. Shared-use medicines that were used for a similar purpose in TM and TCM accounted for 14% of the total, while those used for different purposes accounted for 49% of the total, with some of the latter being commonly used in TCM. Shared-use medicinal herbs that originated from both Tibetan and Han regions accounted for 49% of the total, and those that were imported from South Asia and Southeast Asia were frequently observed in TM. CONCLUSION: Owing to its unique geographical location and cultural diversity, the Tibetan region played a role as a development cradle for various traditional medicinal theories and knowledge. Medicinal knowledge was exchanged between TM and TCM during their parallel independent growth. Shared-use medicines in TM and TCM were mostly determined by flora similarity and medicinal trade, and they marked significant differences in their medicinal properties. However, medicines that were used for similar purposes in TM and TCM presented obvious commercial medicinal characteristic as well as the same chemical profile. The Tibetan region not only provided medicinal usage knowledge of TCM, but also served as a supply of medicinal resources attributing to "high altitude" locations.

The growth parameters,clonal propagation parameters and sexual reproduction parameters of Acanthopanax giraldii population were systematically investigated and analyzed by means of population ecology in this study. The correlation among the above mentioned parameters and the correlation among canopy density,topography and soil fertility factors were analyzed. It is clear that there was a significant correlation among the clonal ramets,the fruit production capacity of the cluster and the new shoot production capacity of the A. giraldii. Sexual reproduction and clonal reproduction played an important role in the continuation of the population. Illumination was the key ecological factor that determined growth type. The increase in canopy density changed the population from " group clonal growth" to " guerrilla clonal growth",and the higher stand closure degree and low-strength herb layer competition was a necessary condition for seed germination and colonization. Under the background of natural forest protection and sustainable development of resources,the reproductive characteristics of wild A. giraldii resulted in the decrease of its recoverable quantity.

In this article the classics textual research to the origin of "Zha-xun" was carried out, the ethnobotanical research methods, the origin of visits, key informant interviews, sample collection and textual research were applied in the research. The results showed that the hypothesis of Zha-xun"s origin mainly included "source of mine", "source of feces", "source of monkey menstrual blood" in China. There were "source of fossil", "source of the plant secretion" abroad. The authors had interviewed the villagers at origin, herbalists, Tibetan doctors, herb dealers, foreign scholars for a total of 18 people, and collecting 45 batches medicinal materials. According to ancient Tibetan classics textual and Tibetan medicine doctors' views, medicinal materials were divided into the genuine and the substitutes. The genuine was identified as ancient so-called "iron" type "Zha-xun", and the substitute was fecal pellet bonding briquette. According to the field survey and literature research, "source of fossil" more in line with substance of Zha-xun was derived from the rock. As the results, the author believed that Zha-xun was the mixture of organic fossils from the rock seepage with flying squirrel, pika feces. So it is needed to be set up Zha-xun classification standard to evaluate the quality of medicinal materials. Meanwhile, it was necessary to further clarify fecal pellet substitute rationality. Above all, this article clarified the status of the use of Tibetan medicine-"Zha-xun", and laid the foundation of species systematics and quality standards research of "Zha-xun".

OBJECTIVE: To study the material composition of Tibetan medicine "Brag-zhun", and to provide the basis for interpretation of its source and reference for the establishment of quality standards. METHODS: Pharmacognosy routine method was used in macroscopic and microscopic identifications, inductively coupled plasma spectrometry was carried out to determine 26 kinds of mineral elements,and X-ray diffraction analysis was used for the crystalline phase detection of Brag-zhun. The content of calcium,organic matter, humic acid and fulvic acid was determined according to GB/T 14610-2008, "technical specification for soil analysis" , GB/T 11957-2001 and capacity titration, respectively. Moisture, ash content, acid insoluble ash content and water soluble extract were determined with reference to the Chinese Pharmacopoeia (2010 edition). RESULTS: Animal feces were commonly found in Brag-zhun, the main crystal phase was SiO2, 26 kinds of mineral elements content in total was about 3%, 13 batches of medicinal materials in organic matter content was 29.03%-71.79%. Humic acid content was 28.37%-58.51%; fulvic acid content was 19.69%-41.43%; moisture was 5.2% -11.7%; total ash content was 17.82%-64.39%; acid insoluble ash content was 2.10%-39.09%; and water soluble extract was 28.39%-57.40%. CONCLUSION: The traditional record of Brag-zhun from molten juice is lack of scientific basis. The mineral elements in Brag-zhun exist in amorphous. Brag-zhun contains a lot of organic matter including humic acid and fulvic acid, and inorganic matter mainly comes from sediment. The organic matter in rock has gone through a long geological evolution.
