ETHNOPHARMACOLOGICAL RELEVANCE: Mushrooms in the genus Hericium are used as functional food and traditional medicines for a long history in East Asian countries such as China, India, Japan, and Korea. Some species of Hericium are called as monkey head mushroom (Houtougu) in China and Yamabushitake in Japan, which are traditionally considered as rare and precious health promoting food and medicinal materials for the treatment of dyspepsia, insomnia, chronic gastritis, and digestive tract tumors. THE AIM OF THE REVIEW: This review aims to summarize the ethnopharmacology and structural diversity of secondary metabolites from Hericium species, as well as the pharmacological activities of the crude extracts and pure compounds from Hericium species in recent years. MATERIALS AND METHODS: All the information was gathered by searching Scifinder, PubMed, Web of Science, ScienceDirect, Springer, Wiley, ACS, CNKI, Baidu Scholar, Google Scholar databases and other published materials (books and Ph.D. and M. Sc. Dissertations) using the keywords "Hericium", "Traditional uses", "Chemical composition", "Quality control" and "Pharmacological activity" (1971-May 2023). The species name was checked with https://www.mycobank.org/. RESULTS: The traditional uses of Hericium species were summarized, and 230 secondary metabolites from Hericium species were summarized and classified into six classes, mainly focusing on their chemical diversity, biosynthesis, biological activities. The modern pharmacological experiments in vivo or in vitro on their crude and fractionated extracts showed that the chemical components from Hericium species have a broad range of bioactivities, including neuroprotective, antimicrobial, anticancer, α-glucosidase inhibitory, antioxidant, and anti-inflammatory activities. CONCLUSIONS: The secondary metabolites discovered from Hericium species are highly structurally diverse, and they have the potential to be rich resources of bioactive fungal natural products. Moreover, the unveiled bioactivities of their crude extracts and pure compounds are closely related to critical human health concerns, and in-depth studies on the potential lead compounds, mechanism of pharmacological effects and pharmaceutical properties are clearly warranted.

ETHNOPHARMACOLOGICAL RELEVANCE: Sa-Tri-Lhung-Klod (ST) remedy is a Thai traditional remedy used in obstetrics and gynecology to reduce inflammation and nourish the body post-partum. In Thai traditional medicine (TTM), there is a theory of formulating drugs based on the four elements and the tastes of herbs for use in treating diseases. AIMS OF STUDY: To determine relationships between taste theory and pharmacological properties for the anti-inflammatory effect of ST remedy and its chemical constituent components. To evaluate anti-inflammatory activity and also investigate the HPLC fingerprint of ST extracts. MATERIALS AND METHODS: ST remedy was extracted by maceration in 95% ethanol (STE) and decoction in distilled water (STW). ST extracts were evaluated for anti-inflammatory activity by nitric oxide inhibitory assay in RAW264.7 cells, carrageenan-induced rat paw edema, and prostaglandin E2 inhibitory assay in inflamed rat paw tissue. In addition, the chemical constituent fingerprints of ST extracts were examined using HPLC. RESULTS: STE contained seven main chemical compounds, and STW demonstrated only one identifiable chemical compound. The STE and STW displayed potent NO inhibitory activity with an IC50 value of 20.59 ± 0.03 and 52.93 ± 0.90 µg/mL, respectively. Moreover, the STE and STW (at doses of 100 - 400 mg/kg) promoted significant inhibition of inflammation in carrageenan-induced paw edema in rats (20.81 - 38.25%). Additionally, the STE (200 - 400 mg/kg) and STW (100 - 400 mg/kg) significantly reduced PGE2 levels in inflamed rat paw tissue. CONCLUSION: These findings suggest that the spicy, astringent, sweet, and fragrant taste of the ST remedy used to treat post-partum inflammation encompass constituents with potent anti-inflammatory activity. STE and STW possess anti-inflammatory properties and effectively inhibit the production of NO and PGE2. Results confirm the use of the ST remedy for treating inflammatory diseases in the post-partum period according to TTM knowledge.

ETHNOPHARMACOLOGICAL RELEVANCE: The botanical characteristics of twinning, climbing vine plants conceptually take shape to interlink the meridians and collaterals system throughout the human body by expelling climatic evils (e.g., wind, dampness). Thus, vines have displayed great medicinal properties in traditional Chinese medicine (TCM). AIM OF THE STUDY: Although some popular vine species have been intensively investigated, the comparable features and medicinal specifications among a vast collection of taxonomic groups based on data visualization methods are relatively lacking in attention. Moreover, the translatability of vines from ancient ethnomedical evidence to modern medical system has not been well established. This review tends to quantitatively summarize the strength of vines in healthcare from the perspectives of medicinal part, traditional function, clinical spectrum, phytochemistry divergence, pharmacological attributes, toxicity as well as the progress of proprietary drug development. MATERIALS AND METHODS: Medicinal vines were retrieved from databases of drug standards and curated catalogues. Synonyms of plant origin across different datasets were normalized by accepted scientific names in the World Flora Online. The distribution patterns and rank of plant origin, medicinal parts, traditional functions and target conditions, as well as the correlation between phytochemical composition and clinical applications were analyzed and visualized. RESULTS: A total of 121 crude drugs from 36 families, 77 genera, 133 species of vines were obtained and analyzed. The Fabaceae, Menispermaceae and Rubiaceae were the highest ranked families of medicinal vines. Not surprisingly, stem was the most dominant medical part. Moreover, "eliminate wind" displayed a hub node in the traditional function co-occurrence network. In addition to joint impediment disorders, these vines particularly displayed a wide range of therapeutic modalities toward conditions from various organ systems. Chemotaxonomic properties-oriented phytochemical analysis was performed and the chemical diversity among medicinal vines complementarily determined a certain group of therapeutic domains. Particularly, the anti-inflammatory effect and antiarthritic effect were highlighted for treating rheumatic diseases. Using integral animal models and cultured cells, modern pharmacological actions of medicinal vines have been largely observed and validated according to their traditional ethnopharmacology. Furthermore, a small proportion of vine species are well-known toxic plants. Successful drug development pipelines in rheumatic, cardiovascular, liver, malignant and infectious diseases have offered the capacity to generate new treatment options that are being sought out from vine plants. CONCLUSIONS: Medicinal vines are rich sources of Chinese Material Medica (CMM) and good fit for a variety of clinical manifestations beyond arthritis and rheumatic diseases. In addition to stem, other parts are also popular for both medicines and dietary supplements. Vine plants provide extensive biologically relevant chemical space for developing value-creating drugs. Thus, our analysis can be useful for further motivating and strengthening the preclinical and clinical research of vine-derived remedies.

ETHNOPHARMACOLOGICAL RELEVANCE: Cuachalalate (Amphipterygium adstringens) stem bark has been used to heal wounds and counteract microbial infections since pre-Hispanic times. However, its effect in treating infected burns remains unclear. STUDY OBJECTIVES: To determine the antipathogenic capacity of a folk remedy (FR) containing cuachalalate stem bark to treat lesions caused by thermal damage and bacterial infection. MATERIALS AND METHODS: The antipathogenic capacity of the hexanic extract (HE) and FR was evaluated in a burned mouse model infected with Pseudomonas aeruginosa. Second to third-degree burns were induced with 95 °C water in CD1 mice in similar ratios of males to females. The mice were randomly grouped into non-inoculated (Group 1) and P. aeruginosa inoculated. The latter were divided into untreated infection (Group 2) and infection topically treated with HE (Group 3), silver sulfadiazine (Group 4), and tween 80 (Group 5). In the case of FR, the lesions were washed with an aqueous extract (AE) and applied powdered stem bark (Group 6). Animal survival, establishment of the bacteria in the lesions, and systemic dispersion were determined. In addition, histopathological analysis was performed. The chemical composition of the AE was analyzed through molecular networking analysis, and the antivirulence capacity was determined through the inhibition of pyocyanin production and caseinolytic activity. RESULTS: Only the FR showed antipathogenic activity and increased animal survival by 50% by reducing the systemic dispersion of P. aeruginosa. In addition, it stimulated the formation of granulation tissue and the generation of new blood vessels. The AE did not show bactericidal activity but reduced bacterial virulence, and glycosylated flavonoids and catechins were identified as its main constituents. CONCLUSIONS: The results of this study contribute to validating the effectiveness of a popular remedy containing cuachalalate stem bark for treating burns infected with P. aeruginosa.

ETHNOPHARMACOLOGICAL RELEVANCE: Tangchong (à½à½à¼à½à¾²à½¼à½à¼), a term in the Tibetan language, encompasses a diverse group of plants belonging to different genera of the Solanaceae family. These plants have been utilized in traditional Tibetan medicine for centuries and are currently still employed to treat a variety of ailments, including acute and severe abdominal pain, intestinal obstruction, epilepsy, ascariasis, lung abscess, and other diseases. The therapeutic properties of tangchong are attributed to the presence of tropane alkaloids (TAs), although recent research has also revealed their toxicity. AIM OF THIS REVIEW: The purpose of this review is to provide a comprehensive analysis of the traditional uses of tangchong, as well as the phytochemical and pharmacological studies conducted on this plant. The review aims to offer a critical update on the current state of knowledge of tangchong and to identify new opportunities for exploring its therapeutic potential. MATERIALS AND METHODS: To gather information on tangchong, we conducted a thorough search of several scientific databases, including Google Scholar, Web of Science, Scifinder, Baidu Scholar, PubMed, and CNKI. RESULTS: This review summarizes the traditional usage of 11 plants, 168 chemical components, including alkaloids, flavonoids, steroids, amides, coumarins, etc., describes the pharmacological activities of these medicinal plants and their mechanisms of action, provides an elaboration of toxicology, and provides new plant-derived drugs and herbal preparations from tangchong. CONCLUSIONS: Clarity regarding the source of the drug is crucial to ensure the safety and efficacy of clinical applications of Tibetan medicine. In this paper, we provide a comprehensive review of tangchong, including its traditional medicinal uses, chemical composition, pharmacology, toxicology, and quality control measures. Our analysis highlights the significant value of tangchong as an ethnomedicinal resource, with pharmacological activities primarily linked to its alkaloid content. Furthermore, this review serves as a valuable reference for future research on alkaloid-containing ethnomedicines.

ETHNOPHARMACOLOGICAL RELEVANCE: Sexual dysfunction is a multifactorial health condition characterized by distressing disturbances in the sexual response and libido, leading to an inability to maintain penile erection and achieve pleasure. Considering the huge Brazilian biodiversity, many plants are traditionally used for aphrodisiac purposes. However, the use of native medicinal plants as sexual boosters in Brazil has been poorly studied. AIM OF THE STUDY: This review focuses on the composition, pharmacology, and results of experimental trials of the main native plants used in Brazilian folk medicine with alleged aphrodisiac effects. We aimed to provide a state-of-the-art reference for research on herbs for the treatment of male sexual dysfunction by summarizing and discussing the main studies found. MATERIALS AND METHODS: The relevant information was collected by searching keywords (aphrodisiac, sexual tonic, sexual stimulant, sexual vigor stimulant, sexual impotency, erectile dysfunction, etc.) from books containing primary surveys conducted in the original communities and bibliographic surveys prepared by authors linked to the national academic and scientific environment edited in Brazil. Preclinical and clinical studies of the compiled plant species were performed using scientific databases (Scopus, PubMed, SciELO, and SciFinder). RESULTS: Seventy-four plant species belonging to 44 families used in Brazil to treat sexual dysfunction were compiled from ethnopharmacological literature. Fourteen plants, including Pfaffia glomerata (Spreng.) Pedersen, Aspidosperma quebracho-blanco Schltdl., Anemopaegma arvense (Vell.) Stellfeld ex de Souza, Mimosa pudica L., Heteropterys tomentosa A. Juss., Trichilia catigua A. Juss., and Turnera diffusa Willd. ex Schult. were pharmacologically studied to confirm these therapeutic properties. Probable modes of action include antioxidant and androgenic activities, inhibition of the PDE5 enzyme, increase in NO levels, and activation of dopaminergic and noradrenergic pathways. In addition, several different species popularly known as "catuaba" were identified, leading to adulterations and controversial effects. CONCLUSION: The overall results of the present review of Brazilian folk literature reveal that Brazil has a long tradition of using plants with potential aphrodisiac effects. However, further research is required to identify, characterize, and standardize the active ingredients and herbal preparations used in aphrodisiacs.

ETHNOPHARMACOLOGICAL RELEVANCE: Amla (Phyllanthus emblica) fruit has been emphasized as a hair tonic in Traditional Persian Medicine (TPM) and recommended for hair loss orally and topically. AIM OF THE STUDY: This study aimed to investigate the effect of an oral product containing Amla fruit on Female Androgenetic Alopecia (FAGA). MATERIALS AND METHODS: This study was a triple-blind, randomized, controlled clinical trial. Sixty women with FAGA were randomly assigned into two groups of thirty. The intervention group received ten cc Amla syrup thrice a day for 12 weeks. The second group received a placebo with the same dose and duration. Hair growth parameters were analyzed using TrichoScan before and after 12 weeks of intervention. Physician and patient satisfaction were assessed using the CGI-I and PGI-I questionnaires, respectively. RESULTS: Twenty-seven participants in the intervention group and 25 in the placebo group completed the trial. Based on our findings, the anagen-to-telogen ratio increased significantly in the intervention group compared with the group who received placebo (F = 10.4, P = 0.002). Physician and patient satisfaction increased in the amla group compared with placebo at 12th weeks of intervention (P<0.001), (P<0.001). The formula had no remarkable side effects. Only one case of mild constipation was reported in one of the participants after one month of consuming Amla syrup. CONCLUSION: The results of this study demonstrated that Amla syrup could help treat androgenic hair loss in women and increase the anagen phase. Further studies are needed to evaluate this potential treatment for FAGA.

ETHNOPHARMACOLOGY RELEVANCE: In Mexico, Agastache mexicana subsp. mexicana (PT) and subsp. xolocotziana (WT), and Dracocephalum moldavica (BT), are used together as the "three toronjiles" to treat gastrointestinal spasms. AIM OF STUDY: To evaluate if the spasmolytic activity of these three medicinal species is better in combination or in an individual manner. MATERIALS AND METHODS: Spasmolytic effect of PT, WT and BT alone or combinate were evaluated in rings of the guinea-pig ileum contracted with potassium chloride (KCl), electrical field stimulation (EFS), or acetylcholine (ACh). Chemical analysis by thin layer and ultra-high pressure liquid chromatography of the aqueous extracts of each species were done for their comparison, and their acute toxicity were determined in mice. RESULTS: PT and WT diminished in a dose-dependent manner the contractions induced by KCl, EFS, and ACh. Whereas BT did not altered contractions in any experimental protocol. A combination of the PT (EC50) and WT (EC50) diminished the contractions induced by KCl or EFS. Interestingly, the addition of BT extract (10 µg/ml) to the combination (PT EC30 + WT EC30) blocked the inhibitory effect produced on the contracted tissue in the presence of KCl, EFS, or ACh. Moreover, addition of BT extract (100 µg/ml) to the same combination blocked the inhibitory effect on the pre-contracted tissue only in the presence of EFS. None of the aqueous extracts produced toxicity in its individual administration in mice. Chemical analysis demonstrated similarities between PT and WT, but differences with BT. CONCLUSIONS: The results of this study confirmed that either combined or by themselves aqueous extracts of PT and WT produced a spasmolytic action on guinea pig ileum, suggesting that this combination of medicinal plants could relieve gastrointestinal diseases in human, but when BT aqueous extract is added to those obtained with PT and WT, the spasmolytic activity diminished or even was blocked. Our results give evidence that mixture of several plants might produce disadvantages in the medicinal properties of their individual activity.

ETHNOPHARMACOLOGICAL RELEVANCE: Natural products, particularly medicinal plants, have been utilized in traditional medicine for millennia to treat various diseases. The genus Balanophora (Balanophoraceae) consists of 23 accepted species. These species are the most controversial flowering plants, with highly reduced morphologies and are found parasitizing on the roots of their host. They have been used in traditional medicine as a remedy for stomach pain, detumescence, uterine prolapse, wounds, syphilis, gonorrhea, treating injuries from falls, and other conditions. However, there is no review of this genus on its traditional uses, phytochemistry, and pharmacology. AIM: The present narrative review discusses the scientific data supporting the traditional uses of Balanophora species. The available information on its botanical properties, traditional uses, chemical contents, pharmacological activities, and toxicity was summarized to help comprehend current research and offer a foundation for future research. MATERIALS AND METHODS: The materials used in combining data on the genus Balanophora comprises online sources such as Web of Science, Google Scholar, Science Direct, and Chinese National Knowledge Infrastructure (CNKI) for Chinese-related materials. World Flora online was used in validating the scientific names of this genus while ChemBio Draw Ultra Version 22.2 software was employed in drawing the phytochemical compounds. RESULTS: Nine Balanophora species including B. harlandii, B. japonica, B. polyandra, B. fungosa, B. fungosa subsp. indica, B. laxiflora, B. abbreviata, B. tobiracola, and B. involucrata have been documented as vital sources of traditional medicines in different parts of Asia. A total of 159 secondary metabolites have been isolated and identified from the ten species of this genus comprising tannins, flavonoids, sterols, lignans, chalcones, terpenes, and phenylpropanoids. Among these compounds, tannins, lignans, terpenoids, chalcones and phenolic acids contribute to the pharmacological activities of the species in this genus with several biological activities both in vitro and in vivo such as anti-inflammatory, anti-oxidant, hypoglycemic activity, cytotoxicity, anti-microbial, melanin synthesis etc. CONCLUSION: This review summarizes the available literature on the traditional uses, pharmacological properties, and phytoconstituents of Balanophora species indicating that they contain fascinating chemical compounds with diverse biological activities. The traditional uses of the species in this genus have been confirmed by scientific data such as antimicrobial, hemostatic effect, gastroprotective activity and others. However, many species in this genus are yet unknown in terms of their botanical uses, chemical composition and biological activities. Thus, more research into the scientific connections between traditional medicinal uses and pharmacological activities, mode of action of the isolated bioactive constituents, and toxicity of other Balanophora species is needed to determine their efficacy and therapeutic potential for safe clinical application.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Crataegus (hawthorn), a member of the Rosaceae family, encompasses several species with broad geographical distribution across the Northern Hemisphere, including Asia, Europe, and the Americas. Hawthorn is recognized as an edible medicinal plant with applications related to strengthening the digestive system, promoting blood circulation, and resolving blood stasis. AIM OF THE REVIEW: This study critically summarized the traditional uses, phytochemistry, and pharmacological properties to provide a theoretical basis for further studies on hawthorn and its applications in medicine and food. MATERIALS AND METHODS: The available information on hawthorn was gathered from scientific databases (including Google Scholar, Web of Science, PubMed, ScienceDirect, Baidu Scholar, CNKI, online ethnobotanical databases, and ethnobotanical monographs, and considered data from 1952 to 2023). Information about traditional uses, phytochemistry, pharmacology, and safety concerns of the collected data is comprehensively summarized in this paper. RESULTS: The literature review revealed that hawthorn includes more than 1000 species primarily distributed in the northern temperate zone. Traditional uses of hawthorn have lasted for millennia in Asia, Europe, and the Americas. Within the past decade, 337 chemical compounds, including flavonoids, lignans, fatty acids and organic acids, monoterpenoids and sesquiterpenoids, terpenoids and steroids, have been identified from hawthorn. Modern pharmacological studies have confirmed numerous bioactivities, such as cardiovascular system influence, antitumor activity, hepatoprotective activity, antimicrobial properties, immunomodulatory functions, and anti-inflammatory activities. Additionally, evaluations have indicated that hawthorn lacks toxicity. CONCLUSIONS: Based on its traditional uses, chemical composition, and pharmacological studies, hawthorn has significant potential as a medicinal and edible plant with a diverse range of pharmacological activities. Traditional uses of the hawthorn include the treatment of indigestion, dysmenorrhea, and osteoporosis. However, modern pharmacological research primarily focuses on its cardiovascular and cerebrovascular system effects, antitumor effects, and liver protection properties. Currently, there is a lack of correlative research involving its traditional uses and pharmacological activities. Moreover, phytochemical and pharmacological research has yet to focus on many types of hawthorn with traditional applications. Therefore, it is imperative to research the genus Crataegus extensively.

Works published in the format of original articles, available online, free and complete, in Portuguese and English, were considered. These articles were consulted in different databases. The integrative analysis showed the characteristics of the publications, such as the concentration of studies directed to the states of Bahia, Paraíba and Pernambuco, as well as demonstrating a rich diversity of medicinal plants that are used by the population in the northeastern semi-arid region, highlighting, mainly, the knowledge traditional practices about their forms of use and therapeutic properties.
La vegetación de la Caatinga es rica en una diversidad de especies vegetales utilizadas para satisfacer las necesidades humanas. Muchas de estas especies son utilizadas con fines terapéuticos por las poblaciones. Las formas de uso de estas especies pueden ser registradas y rescatadas a través de estudios etnobotánicos, que contribuyen al levantamiento del potencial de los recursos vegetales, así como a los planes de recuperación y conservación de la vegetación. Así, a partir de una revisión integradora, el presente trabajo buscó recopilar información sobre cómo se están desarrollando los trabajos etnobotánicos sobre plantas medicinales, así como sobre las principales especies y familias botánicas con potencial medicinal descritas, en relevamientos realizados en áreas de caatinga ubicadas en la región semiárida del Nordeste. Para ello, se seleccionaron artículos publicados entre los años 2010 y 2022 que abordaran la temática relacionada. Se consideraron trabajos publicados en formato de artículos originales, disponibles en línea, gratuitos y completos, en portugués e inglés. Estos artículos fueron consultados en diferentes bases de datos. El análisis integrador mostró las características de las publicaciones, como la concentración de estudios dirigidos a los estados de Bahía, Paraíba y Pernambuco, además de demostrar una rica diversidad de plantas medicinales que son utilizadas por la población de la región semiárida del nordeste, destacándose, principalmente, los conocimientos tradicionales sobre sus formas de uso y propiedades terapéuticas.

The vast majority of studies on traditional medicine disregard the existence of biomedicine and alternative and complementary medicines in the lives of the indigenous peoples of Mexico and Latin America in general, despite the fact that these populations increasingly make use of biomedical knowledge more and more intensively. In this text I have attempted to elucidate this expansion of biomedicine and the decline of traditional medicine, through ethnographic information related to different indigenous groups. This expansion of biomedicine takes place despite the various negative consequences it generates due to different factors such as its comparative effectiveness, which is evidenced in the use of and demand for pharmaceuticals, biomedical services, and in particular the construction of hospitals in their communities. The indigenous population combines the uses of traditional medicine and biomedicine with a tendency to increasingly utilize biomedicine, even on the part of traditional healers.
La gran mayoría de los estudios de la medicina tradicional excluyen la existencia de la biomedicina y de las medicinas alternativas y complementarias en la vida de los pueblos indígenas de México y de Latinoamérica en general, pese a que estos pueblos utilizan la biomedicina en forma creciente e intensa. En este texto, he tratado de poner de manifiesto este proceso de expansión biomédica y de declive de la medicina tradicional, a través de información etnográfica referida a distintos pueblos originarios. Esta expansión biomédica se desarrolla a pesar de las varias consecuencias negativas que genera, debido a diversos factores, entre ellos, su eficacia comparativa, que se expresa a través de los usos y la demanda de fármacos, de los servicios biomédicos y, en particular, de la instalación de hospitales en sus comunidades. La población indígena articula los usos de la medicina tradicional y de la biomedicina con la tendencia a utilizar cada vez más la biomedicina, incluso por parte de los curadores tradicionales.

Clinacanthus nutans (Burm. f.) Lindau has been extensively utilized in Thai folk medicine. However, there has been no prior exploration of its genetic diversity or its correlation with biological activity and phytochemical profiles. Herein, a total of 10 samples of C. nutans were collected from different geographic locations in different environments of Thailand, encompassing Northern, Northeastern, and Central regions. The genetic diversity study using sequence-related amplified polymorphism (SRAP) markers showed that all C. nutans samples were closely related, as indicated by UPGMA cluster analysis. When comparing the biological activities of C. nutans extracts, our findings demonstrated that those sourced from Northern Thailand exhibited the most potent activity in reducing lipopolysaccharide-inducing cell death, as accessed by cell viability assay. Furthermore, they showed remarkable antioxidant and antibacterial activities against Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. High-performance liquid chromatography (HPLC) analysis of phytochemical profiles revealed consistent chromatography peak patterns across all C. nutans extracts. However, they exhibited varying levels of phenolic contents, as judged by the Folin-Ciocalteu assay, which positively correlated with their observed activities. In conclusion, this study highlights the limited genetic variation within C. nutans population in Thailand. Furthermore, it underscores the association between the biological activity and the total phenolic contents which might be mainly impacted by environmental conditions.

As culturally friendly countries, China and the Korean Peninsula have had active medical exchanges throughout history, which had a significant impact on the traditional medicine industry and daily life of both sides. Ginseng is an important commodity in the drug trade between China and Korea, and its profits are lucrative and an important source of fiscal revenue for the Korean government.In modern times, lured by huge profits, some Korean and Chinese businessmen have engaged in ginseng smuggling, even government officials.In order to safeguard the interests of the official camp, the two governments have always severely punished smuggling, but ginseng smuggling has not disappeared, and the game between official and private ginseng has become a unique phenomenon in the medical exchanges between China and Korea.

Ethnobotanical studies that use the participatory research approach seek to involve the residents of a community in different stages of the study, promoting the registration, dissemination and strengthening of local knowledge, as well as the empowerment of decisions related to the sustainable use and management of resources. Using the participatory methodology, this study recorded and made a comparative analysis on the use of plants in two quilombola communities (Quilombo do Cambury-QC and Quilombo da Fazenda-QF) in the State of São Paulo. After a training on anthropological and botanical methods, local researchers selected and interviewed the local experts, recording their knowledge on plant uses and collecting the indicated plants, to be identified and deposited in herbariums. In addition, participant observation and field diaries were used by the academic researchers, helping to analyze the data. To test the differences in the composition of species known to local community, a Jaccard dissimilarity matrix was created, and a Permanova test was employed. During the 178 days of fieldwork, three local researchers from the QC and two from the QF, selected nine and eight experts on the uses of the plants in each quilombo, respectively, corresponding to 214 plant species, indicated for eight ethnobotanical categories. Our hypothesis has been confirmed, since the traditional knowledge found in both quilombos, regarding plant uses and the number of plant species by category, are distinct, since each community occupies particular plant areas and different phytophysiognomies. Most of the indicated species are native to the Atlantic forest, and no significant differences were observed in the proportion of native species vs. introduced among quilombos for any of the categories of use studied. Furthermore, the innovative methodology used, participatory ethnobotany, contributed to the empowerment of community members with regard to the use of their available resources in the environment in which they live, while retaining the intellectual property rights over their own knowledge.

When the COVID-19 pandemic struck and China reported the first case to the World Health Organization in December 2019, there was no evidence-based treatment to combat it. With the catastrophic situation that followed, materialised by a considerable number of deaths, researchers, doctors, traditional healers, and governments of all nations committed themselves to find therapeutic solutions, including preventive and curative. There are effective treatments offered both by modern medicine and traditional medicine for COVID-19 today. However, other therapeutic proposals have not been approved due to the lack of effectiveness and scientific rigour during their development process. Proponents of modern medicine prefer biomedical therapies while in some countries, traditional treatments are used regularly because of their availability, affordability and satisfaction they bring to the population. In this paper, we propose a transactional medicine approach where the interaction between traditional and modern medicine produces a change. With this approach, the promoters of traditional medicine and those of modern medicine will be able to acquire knowledge through the experience produced by their encounters. Transactional medicine aims to be a model for decolonising medicine and recognising the value of both traditional and modern medicine in the fight against COVID-19 and other global emerging pathogens.
