Exotic medicinal plants from the Silk Road promote the diversification of traditional Chinese medicines.

BACKGROUND: As a political, economic, and cultural exchange channel between ancient China and countries in Asia, Europe, and Africa, the Silk Road has promoted political, trade, and cultural exchanges between China and foreign countries in Chinese history and also promoted the development of traditional Chinese medicine. METHODS: This article summarizes the introduction of medicinal materials from the Han to Qing Dynasties, spanning approximately 2000 years. RESULTS: A total of 235 types of medicinal plant materials were imported. An analysis of 178 medicinal herbs of known origin, belonging to 72 families revealed their effectiveness in treating 20 diseases. The maximum number of medicinal herbs used to treat gastrointestinal and digestive disorders (GAS) was 122. The applications and origin of exotic medicinal materials, including draconis sanguis and olibanum have changed during the development of the Silk Road. Imported medicinal materials are affected by five factors, including local demand, adaptability, cultural exchange, scarcity, and medical theory. Five modes for introducing medicinal materials include the onshore Silk Road, the maritime Silk Road, diplomatic envoys and gifts, overseas Chinese, cultural exchange, and medical integration. The application of exotic medicinal materials expands the resources and application fields of traditional Chinese medicine, enriching the theory of traditional Chinese medicine. CONCLUSION: Traditional Chinese medicinal compounds introduced to China through the ancient Silk Road not only promoted their integration into foreign medicine but also had long-lasting impacts to date and over a wide range, thereby considerably affecting the pharmaceutical and general healthcare industries.

An ethnobotanical survey on the medicinal and edible plants used by the Daur people in China.

BACKGROUND: The Daur people are one of the 55 minority ethnic groups in China and have lived in Northern China for 300 years. In traditional Daur medicine, medicinal and edible plants (MEPs) are utilised for health benefits and therapeutic purposes; however, related ethnobotanical knowledge is rarely reported, which is disadvantageous for the sustainable development of these MEPs. METHODS: Semi-structured interviews with 122 informants, six focus group discussions, and a resource survey were conducted in a Daur minority nationality area in Inner Mongolia from 2015 to 2020, and the data statistics were analysed. In this study, we simulated a system dynamics model aimed at understanding the multiple feedback mechanisms involved in the relationships between the cultural influences and socioeconomic factors, sustainable environment, and development of MEPs. RESULTS: A total of 52 species of MEPs were identified and relevant ethnobotanical knowledge was assessed using Daur medicinal species data from Inner Mongolia and the Xinjiang region, with the literature and Ewenki ethnic group data used for comparison. The most commonly used medicinal plant species by the Daur were found to be Betula pendula subsp. mandshurica, Artemisia integrifolia, Crataegus pinnatifida, Saposhnikovia divaricata, Artemisia argyi, and Jacobaea cannabifolia. The MEPs most frequently targeted the digestive and rheumatic immunity systems, as well as infectious diseases or parasitic infections and other common diseases and basic health issues. MEP knowledge was primarily limited to older generations; thus, the valuable ethnobotanical knowledge on traditional medicines must be protected from future losses. CONCLUSIONS: Our findings provide insights for future research aimed at exploiting the rich phytochemical diversity in traditional medicine and promote its use in modern lifestyles. Effective assessment and management of plant resources will lead to their application for the improvement of dietary diversity, nutrition, and health care.

[Comprehensive yield and quality comparison of Bupleurum chinense' s seeds of different harvesting time from Qingchuan County with Topsis approach].

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

'Food and medicine continuum' in the East and West: Old tradition and current regulation.

Food-medicine products are important materials for daily health management and are increasingly popular in the global healthy food market. However, because of the biocultural difference, food-medicine knowledge may differ among regions, which hinders the global sharing of such health strategies. Aim at bridging the food-medicine knowledge in the East and West, this study traced the historical roots of food and medicine continuum of the East and West, which was followed by a cross-cultural assessment on the importance of food-medicine products of China, thereafter, the current legislative terms for food-medicine products were studied using an international survey. The results show that the food and medicine continuum in the East and West have their historical roots in the traditional medicines since antiquity, and the food-medicine knowledge in the East and West differs substantially; although the food-medicine products have common properties, their legislative terms are diverse globally; with proofs of traditional uses and scientific evidence, food-medicine products are possible for cross-cultural communication. Finally, we recommend facilitating the cross-cultural communication of the food-medicine knowledge in the East and West, thus to make the best use of the traditional health wisdom in the globe.

Single botanical drugs in the Ayurvedic Pharmacopoeia of India-A quantitative ethnobotanical analysis.

Developing evidence-based uses of herbal medicines and natural product-based drug discovery are two core aims of ethnopharmacology. This requires an understanding of the medicinal plants and the traditional medical knowledge associated with them which is a basis for cross-cultural comparison. The botanical drugs of traditional medical systems are still not understood well, even for well-known and widely respected traditions like Ayurveda. In this study, a quantitative ethnobotanical analysis was performed on the single botanical drugs included in the Ayurvedic Pharmacopoeia of India (API), presenting an overview on the medicinal plants of Ayurveda from perspectives of plant systematics and medical ethnobotany. Part-I of API includes 621 single botanical drugs, which are sourced from 393 species (323 genera in 115 families). Of these, 96 species yield two or more drugs, together accounting for 238 drugs. Taking the traditional concepts, biomedical uses and the pragmatic disease classification into account, therapeutic uses of these botanical drugs are sorted into 20 categories, which meet primary health demands. The therapeutic uses of the drugs sourced from the same species may differ considerably, but 30 of the 238 drugs are used in highly similar way. The comparative phylogenetic analysis identifies 172 species with high potential for specific therapeutic uses. This medical ethnobotanical assessment for the first time provides a comprehensive understanding on the single botanical drugs in API from the perspective of medical botany using an "etic" (scientist-oriented) approach. This study also highlights the importance of quantitative ethnobotanic methods in understanding traditional medical knowledge.

[Development strategies for green control of medicinal plants diseases in GAP production].

GAP production of medicinal plants needs diseases' green control during their cultivation processes. In this article, The authors summarized the achievements in cultural control and biological control to crops' diseases, taking the characteristics of medicinal plants into account, we put out the notion of the green control to medicinal plants' diseases, and indicated that the green control for medicinal plants' diseases should combine with cultural control, modem phytopathology methods, biological control and essential pesticides, besides, we introduced some suggestions and the prospect, to provide a reference for green control of medicinal plants' diseases in their GAP production.

[Advances in studies on classification of Bupleurum].

This article introduced the herbal medicine studies on Bupleurum in recent years, focused on the classification just like morphological and chemical classification, microscopic characteristics and molecular biology classification for Bupleurum. Identification combined with a variety of classification is the most effective method for Bupleurum. Due to the short supply of Bupleurum in the current market the current Bupleurum classification studies should focuses on combining pharmacological research to expand the Bupleurum's herbal sources.

Identification of the original plants of cultivated Bupleuri Radix based on DNA barcoding and chloroplast genome analysis.

Bupleuri Radix is the dry root of certain species of the genus Bupleurum and is commonly used in traditional Chinese medicine. The increasing global demand for Bupleuri Radix cannot be fulfilled with wild populations only. Therefore, cultivated Bupleurum is now the main commercial source of this medicinal product. Different species of Bupleurum show different medicinal properties and clinical effects, making reliable authentication and assignment of correct botanical origin for medicinal species critical. However, accurate identification of the cultivated Bupleurum species is difficult due to dramatic morphological variations resulting from cultivation. In this study, we sampled 56 cultivated Bupleurum populations of six different morphotypes (Types A-F) from the main production areas of China, and 10 wild populations of four species were used as reference materials. Conventional DNA barcoding was conducted to identify cultivated Bupleurum species. Additionally, verification based on complete chloroplast genomes was performed and new chloroplast markers were developed and evaluated. The combination of these methods resulted in the successful identification of all cultivated Bupleurum individuals. Three chloroplast regions are recommended as additional barcodes for the genus: ycf4_cemA, psaJ_rpl33, and ndhE_ndhG. This is a reliable and promising strategy that can be applied to the authentication of natural products and the identification of other medicinal plant species with similar taxonomic problems.

[Advances of studies on seed biology of Bupleurum chinense].

Bupleurum chinense is a commonly used Chinese medicinal material, which has been used medicinally in China for over 2000 years, the development of it is of great value. There have been great advances of studies on its embryology and seed biology in recent years. In this paper, we make a review of the growth of its embryo and fruit, the characteristics of dormancy and storage and the germination of its seed. Besides, we summarize the reasons of its low germination rate and the achievements in improving the situation, for the purpose of providing reference in research on seed physiology of B. chinense.

Cross-Cultural Ethnobotanical Assembly as a New Tool for Understanding Medicinal and Culinary Values-The Genus Lycium as A Case Study.

Ethnobotanical knowledge is indispensable for the conservation of global biological integrity, and could provide irreplaceable clues for bioprospecting aiming at new food crops and medicines. This biocultural diversity requires a comprehensive documentation of such intellectual knowledge at local levels. However, without systematically capturing the data, those regional records are fragmented and can hardly be used. In this study, we develop a framework to assemble the cross-cultural ethnobotanical knowledge at a genus level, including capturing the species' diversity and their cultural importance, integrating their traditional uses, and revealing the intercultural relationship of ethnobotanical data quantitatively. Using such a cross-cultural ethnobotanical assembly, the medicinal and culinary values of the genus Lycium are evaluated. Simultaneously, the analysis highlights the problems and options for a systematic cross-cultural ethnobotanical knowledge assembly. The framework used here could generate baseline data relevant for conservation and sustainable use of plant diversity as well as for bioprospecting within targeting taxa.

Traditional uses, phytochemistry, pharmacology, and toxicology of Akebiae Caulis and its synonyms: A review.

ETHNOPHARMACOLOGICAL RELEVANCE: "Mutong" ( in Chinese, and generally known as Akebiae Caulis), which refers to a group of herbal medicines with different biological origins along history, has been used in traditional Chinese medicine for over 2000 years; it is still being frequently used in medicine. In recent decades, Akebiae Caulis has been reported to exhibit apparent toxicity. AIM OF THIS STUDY: To clarify the plant species used as Akebiae Caulis and its synonyms, and to summarize their phytochemistry, pharmacology, and toxicology. METHODS: Academic search engines (Google Scholar, Baidu Scholar, CNKI, Science Direct, Springer Link, SciFinder, PubMed, Web of Science, and EBSCO), ancient Chinese herbals, and modern medical monographs were used to obtain phytochemical, pharmacological, toxicological, and quality control information. Furthermore, a field survey was conducted to clarify the associated species. RESULTS: Akebiae Caulis is derived from eight species belonging to two families. In the 2005 Pharmacopoeia of The People's Republic of China, it has been separated into two categories: Akebiae Caulis and Clematidis Armandii Caulis. Traditionally, Akebiae Caulis has been used to treat conditions such as gonorrhea, edema, and tongue sores. Pharmacological studies have demonstrated the anti-inflammatory, antitumor, antihypertensive, antibacterial, analgesic, and other properties of Akebiae Caulis. Among the species used, Aristolochiae manshuriensis Kom. (Aristolochiaceae) contains aristolochic acid that has raised concerns globally because of its nephrotoxicity. CONCLUSIONS: Clarifying the biological origin of traditional herbal medicines is critical for their safe and effective use. The present review revealed that the biological origin of Akebiae Caulis is diverse. The traditional uses, phytochemistry, and pharmacology of Akebiae Caulis indicate that it is a useful medical resource. The diversity of its biological and pharmacological activities is associated with the presence of a large number of chemical substances, among which terpenoids are predominant. Systematic reviews on Akebiae Caulis such as this one would provide solid references for its safe use, as well as drug discovery studies in the future.

Dragon's Blood from Dracaena Worldwide: Species, Traditional Uses, Phytochemistry and Pharmacology.

Dragon's blood (DB) refers mainly to the crimson resin of many Dracaena spp. DB has been used by different traditional medicine systems worldwide, including Arabic medicine, African medicine, traditional Chinese medicine, Thai medicine, etc. DB are mainly used to heal wounds, kill pain, stop bleeding, and cure various diseases such as diarrhea, dysentery and ulcers for over 1000 years. 11 Dracaena spp. and 3 subspecies are reported to be able to produce red resin. However, the resources are extremely deficient. Several Dracaena spp. are in threatened status. Over 300 compounds have been isolated from Dracaena spp., mainly including flavonoids, steroids, and phenolics. DB exhibits anti-inflammatory, analgesic, antithrombotic, anti-oxidant, antimicrobial, antidiabetic, and anticancer properties, which explain its wound healing effects, preventive effects on cardiovascular and cerebrovascular diseases, dual-directional regulation of blood flow, neuroprotection and radioprotective effects. No apparent side effects or toxicity have been reported. DB are restricted from being exploited due to limited resources and unclear resin formation mechanism. It is necessary to expand the cultivation of Dracaena spp. and fully understand the mechanism underlying the resin formation process to develop an effective induction method for the sustainable utilization of DB.

What's the choice for goji: Lycium barbarum L. or L. chinense Mill.?

ETHNOPHARMACOLOGICAL RELEVANCE: For over one millennium, goji berries have been used traditionally as food and medicine in eastern Asia. In recent decades, it has become increasingly popular globally. However, the biocultural development of goji is poorly known. The botanical origin of goji is controversial: in many but not all modern regional or international quality standards, L. barbarum is accepted exclusively as the botanical origin of goji. AIM OF THE STUDY: Focusing on historical, biogeographical, botanical, phytochemical and pharmacological data, the overarching aim is to understand the biological origin of goji's historical uses, as well as whether the two species can be used interchangeably. MATERIALS AND METHODS: The taxonomic literature on L. barbarum and L. chinense were analysed, followed by a study of botanical specimens and fieldwork. Historical herbals and gazetteers were employed to define the historical producing areas and medical properties of goji. An identification of the species used in history was carried out. In a final step the phytochemical and pharmacological literature on the species was compared. RESULTS AND DISCUSSION: Due to their morphological similarity and different accessibility, fruits of both L. barbarum and L. chinense have been used interchangeably as food and medicine at least since 682 CE. While the fruit of L. barbarum was recognized to be superior in quality, the fruit of L. chinense was commonly used as an equivalent because of its easier accessibility. Cultivation of L. barbarum in China since 1960s improved its availability, which likely lead to its exclusive use as source of goji in China. The long-term safe use with no reported major safety concerns supports that these two species both are useful sources for medicinal Lycium. CONCLUSIONS: Medicinal plants had been used traditionally long before they were named in scientific nomenclature system. Therefore, the understanding of traditional herbal knowledge and the adequate use of those traditional medicines require a reliable identification based on archival records. This study developed an approach for the identification of species used historically, with an integrated analysis of specimens, historical herbals, and national gazetteers. Additionally, their different chemical profiles and pharmacological activities indicate that they should not be used interchangeably. Further scientific evidence is required for their safe and effective use.

Ethnobotanical study on herbal market at the Dragon Boat Festival of Chuanqing people in China.

BACKGROUND: The Chuanqing people () are a linguistic group native to the Guizhou Province of China, with unique culture and rich knowledge of traditional medicinal plants. Herbal market at Dragon Boat Festival (DBF) plays an important role in the inheritance of traditional medicinal knowledge among the Chuanqing people. This study aims to record the profile of medicinal plants of the Chuanqing people, discuss the dilemmas faced by their inheritance, and propose some strategies for passing down information, which is critical for the inheritance and protection of the Chuanqing people's traditional medical knowledge. METHODS: Data were collected through key informants and semi-structured interviews and free listing. Collected voucher specimens were identified using by botanical taxonomy method and deposited in the herbarium. Data were analyzed through use-value (UV) and cultural importance index (CI) values. Medicinal plants were compared with the Information System of Chinese Rare and Endangered Plants of the Chinese Academy of Sciences. Results were compared with the Pharmacopoeia of the People's Republic of China (ChP), the Quality Standard of Traditional Chinese Medicine and National Medicine in Guizhou Province (QSG), and traditional medicines of Southeast Asian countries. RESULTS: A total of 102 species from 53 families and 92 genera were recorded, with Orchidaceae and Asparagaceae (six species each), and Berberidaceae and Asteraceae (five species each) as the predominant families. The whole plant (36%) was the most common medicinal part. Decoction (44%) was the most common preparation method. Seventy-one investigated human ailments were grouped into 12 categories. Diseases of the musculoskeletal system (34 mentions) were most frequently mentioned in this study. Moreover, the most frequently used taxon was Hedera sinensis (Tobler ) Hand.-Mazz. (UV and CI = 0.29). The Chuanqing people's medicine was highly similar to ChP and QSG. In comparison with Southeast Asian countries' traditional medicines, except for the same preparation methods, the similarities in terms of medicinal ingredients, plants, and disease treatment were very low. CONCLUSIONS: The herbal market at the DBF is an important platform for exchanging knowledge about the Chuanqing people's traditional medicinal plants. The Chuanqing people's traditional medicine is facing many challenges to its inheritance and development. To solve these problems, this study highlights the traditional medicinal knowledge of the Chuanqing people, providing basic data for further research and protection of minority medicine.

The Quality Monitoring of Cistanches Herba (Cistanche deserticola Ma): A Value Chain Perspective.

Cistanche deserticola Ma was used as a medicine food homology, which was mainly produced in the Alxa region of northwest China. In recent years, it has been widely used in various food items. The increasing demand for Cistanches Herba has led to problems such as overexploitation and quality deterioration. The quality and safety of herbal medicines are critical and have been shown to be affected by the value chain (VC). Using the VC framework, the study is embedded in a larger study aiming to investigate the effects of different VCs types on the quality and stakeholders of Cistanches Herba. In this study, 90 Cistanches Herba samples were collected during fieldwork. An additional 40 samples were obtained from the herbal markets and medicine purchasing stations. Semi-structured interviews and key informant interviews were performed to collect data on stakeholders in major production areas. These samples were analyzed using high performance liquid chromatography (HPLC) coupled with the k-means clustering method; a targeted quality assessment strategy based on chemical analysis was adopted to understand the quality of Cistanches Herba. Based on market research, the collected samples were divided into different grades through k-means clustering analysis. Moreover, quality differences of Cistanches Herba in Alxa region were explored through DNA barcoding and chemical analysis. Accordingly, 10 different types of VCs were determined in the production of Cistanches Herba. The results show that there is a close relationship between the quality of Cistanches Herba and stakeholder benefits. Vertical integration at different levels was found for independent farmer-based VCs, horizontal collaboration was found in the cooperative-based VCs. The vertical coordination has led to a more consistent traceability system and strict regulation of supply chains. At the same time, the Cistanches Herba were divided into three grades. Through DNA barcoding and chemical analysis, we found that the quality differences between Cistanches Herba in the Alxa area were not significant. It was found that geographical suitability and vertical integration could impact the quality and sustainable production of Cistanches Herba. At the same time, the well-developed VCs can provide products with reliable quality, and ensure adequate financial revenue for relevant stakeholders.

Quality Control of Radix Astragali (The Root of Astragalus membranaceus var. mongholicus) Along Its Value Chains.

Radix Astragali (RA), the root of Astragalus membranaceus var. mongholicus (Bunge) P.K. Hsiao, known as "Huangqi" in Chinese, has been used as a traditional herbal medicine or food in China for more than 2,000 years and is now consumed globally. Unfortunately, the increasing demand for RA has led to the overexploitation of its wild stock, as well as quality problems, including adulteration and contamination. Therefore, the sustainable cultivation of RA is urgently needed. In the present research, semi-structured interviews and key informant interviews were conducted, over a 2-year period, to collect data from stakeholders in the main production areas; moreover, a targeted chemical analysis-based quality assessment strategy was applied to understand the quality of RA. Accordingly, 10 different types of value chains (VCs) were identified in RA production; meanwhile, the contents of the main active ingredients (astragaloside and calycosin-7-O-ß-D-glucoside) were analyzed by HPLC-ELSD-UV and the yield of medicinal material was demined and further analyzed using k-means clustering analysis. The results show that the tight relationship between quality of the RA and stakeholders' revenues among the VCs, which reflects a more general trend in the production system. Over the past few decades, vertical coordination has emerged increasingly in VCs of RA, which leads to a more coherent traceability system and rigorous regulations in the supply chains. Daodi herbs can be considered to be a standard that is distinctive with good quality characteristics that emphasize the origins of the medicinal plants. We find that the suitability of geographical areas and vertical integration can improve the VCs of RA, which further contributes to its quality control, as well as its sustainable production.

The genus Orobanche as food and medicine: An ethnopharmacological review.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Orobanche consists of annual, biennial or perennial fleshy parasitic herb species, many of which are in use as traditional medicines and wild gathered foods since a long time. Recently, Orobanche spp. are increasingly accepted as edible medicines with nourishing properties. However, there is a lack of comprehensive understanding of their ethnopharmacological background. AIM OF THE REVIEW: This review focuses on the advancements in botanical classification, and summary of traditional use, phytochemistry, pharmacology and toxicology of Orobanche species, in order to check for scientific support of their traditional uses and the safe treatment of human ailments and diseases. MATERIALS AND METHODS: In this review, the results of a systematic and comprehensive literature survey about Orobanche spp over the past 60 years (from 1960 to 2020) is presented. The selected literature includes periodicals, doctoral dissertations, master dissertations conference papers and various books. The literature was identified through search engine websites and a cross-checked with the Chinese pharmacopeia, classic Chinese and European herbals, regional medicinal monographs, and online ethnobotanical databases. RESULTS: The literature about the traditional uses revealed that Orobanche spp. were used as medicine and food in many regions of the world, but mainly in China and North America while in Europe they were primarily used as food items. Phenylpropanoid derivatives and alkaloids, were reported as their main bioactive compounds, showing antioxidant, immune system enhancing, androgenic, antibacterial and antiviral properties. CONCLUSIONS: Orobanche spp. are increasingly being used for tonic purposes in China. Their ethnopharmacological background suggests potential usages as healthy foods and food supplements. They have the potential to be developed into herbal medicines for tonifying the kidney, against impotence and spermatorrhea, dermatological problems and wounds, as well as infantile diarrhoea. However, the pharmacological studies conducted with extracts derived from Orobanche spp. were not useful for rationally explaining the traditional uses. More investigations are required to provide a pharmacological basis for the traditional claims and the relationship between traditional uses, clinical uses, phytochemistry and pharmacological properties. Additionally, quality control should be emphasized to ensure the safe and effective use of Orobanche derived products.

A pectic polysaccharide from water decoction of Xinjiang Lycium barbarum fruit protects against intestinal endoplasmic reticulum stress.

Neutral polysaccharides from Ningxia L. barbarum fruit have been reported with immunomodulatory and antioxidative biological activities. Few studies on pectic polysaccharides have been reported, especially not from the Xinjiang L. barbarum. In the present study, a pectic polysaccharide, XLBP-I-I, was obtained from water decoction of Xinjiang L. barbarum using anion exchange chromatography and gel filtration. The results from methanolysis, methylation, FT-IR and NMR experiments indicated that XLBP-I-I was a typical pectic polysaccharide. In vitro assay showed that XLBP-I-I could reduce the ER stress and UPR in tunicamycin insult IPEC-J2 cells, and further protect IPEC-J2 cells against apoptosis induced by ER stress. These results reveal a new perspective for pectic L. barbarum polysaccharides on intestine ER stress, and this elicited interests for its further applications.

The genus Lycium as food and medicine: A botanical, ethnobotanical and historical review.

ETHNOPHARMACOLOGICAL RELEVANCE: Lycium is widely distributed in the arid to semi-arid environments of North and South America, Africa, and Eurasia. In recent years, Lycium barbarum and L. chinense have been advertised as "superfood" with healthy properties. Despite of its popularity, there is a lack of an integrated and critical appraisal of the existing evidence for the use of Lycium. AIM OF THE STUDY: There is a need to understand: 1) Which species were used and how the uses of Lycium developed spatially and over time, 2) how uses differ among regions with different culture backgrounds, and 3) how traditional and current therapeutic and preventive health claims correlate with pharmacological findings. METHODS: Information was retrieved from floras, taxonomic, botanical, and ethnobotanical databases, research articles, recent editions of historical Chinese herbals over the last 2000 years, and pharmacopoeias. RESULTS: Of totally 97 species, 31 have recorded uses as food and/or medicine worldwide. Usually the fruits are used. While 85% of the Lycium species occur in the Americas and Africa, 26% of them are used, but 9 out of 14 species in Eurasia. In China, seven species and two varieties of the genus Lycium occur, of which four species have been used by different ethnic groups. Only L. barbarum and L. chinense have been transformed into globally traded commodities. In China, based on the name "", their use can be traced back over the last two millennia. Lycium fruits for anti-aging, improving eyesight and nourishment were documented already in 500C.E. (Mingyi Bielu). Recent findings explain the pharmacological foundations of the traditional uses. Especially polysaccharides, zeaxanthin dipalmitate, vitamins, betaine, and mixed extracts were reported to be responsible for anti-aging, improving eyesight, and anti-fatigue effects. CONCLUSIONS: The integration of historical, ethnobotanical, botanical, phytochemical and pharmacological data has enabled a detailed understanding of Lycium and its wider potential. It highlights that the focus so far has only been on two species and that the genus can potentially yield a wide range of other products with different properties.
