In addition, this review also aims to provide advance and sensitive analytical methods along with chemical markers used in the standardization of herbal products for quality control (QC)/quality assurance (QA). MATERIALS AND METHODS: All relevant publications were considered within the years 1983-2020. The publications were searched from Google Scholar, PubChem, Chemspider, PubMed, Elsevier, Wiley, Web of Science, China Knowledge Resource Integrated databases and ResearchGate using a combination of various relevant keywords. Besides, relevant published books and chapters were also considered those providing an overview of extant secondary literature related to traditional knowledge, phytochemistry, pharmacology and toxicity of the plant. RESULTS AND DISCUSSION: In this review, 344 compounds, including, terpenoid lactones, flavonoids, phenolic acids, triterpenes and volatile compounds were summarized out of which more than half of the compounds have no reported pharmacological activities yet. Terpenoid lactones and flavonoids are the major bioactive classes of compounds of A. paniculata which are responsible for pharmacological activities such as anticancer and antioxidant activities, respectively. Biosynthetic pathways and active sites for target proteins of both terpenoid lactones and flavonoids were considered. Analgesic, anticancer, antidiabetic, antifertility, antiinflammatory, antimalarial, antimicrobial, antioxidant, antipyretic, antiviral, antiretroviral, antivenom, cardioprotective, hepatoprotective, immunomodulatory and neuroprotective activities have been also reported. Andrographolide is a major characteristic active principle and responsible for most of the pharmacological activities. Therefore, andrographolide has been selected as a marker for the standardization of raw and marketed herbal products by TLC, HPTLC, HPLC, GC-MS, HPLC-MS and HPLC-MS/MS methods for QC/QA. CONCLUSIONS: Conclusive evidence showed that the pharmacological activities reported in crude extracts and chemical markers are supporting and provides confidence in the traditional use of A. paniculata as a herbal medicine. The andrographolide could be used as a chemical marker for the QC/QA of raw and A. paniculata derived herbal products. Lactone ring in terpenoid lactone is an active site for targeted proteins. More efforts should be focused on the identification of the chemical markers from A. paniculata to provide a practical basis for QC/QA. Several aspects such as the mechanism of therapeutic potential, molecular docking technology and multi-target network pharmacology are very important for drug discovery and needed more investigation and should be considered. This compilation may be helpful in further study and QC/QA.

Chemotaxonomy of the ethnic antidote Aristolochia indica for aristolochic acid content: Implications of anti-phospholipase activity and genotoxicity study.

ETHNOPHARMACOLOGICAL RELEVANCE: Aristolochia indica L. (Aristolochiaceae) is a common medicinal plant described in many traditional medicine as well as in Ayurveda used against snakebites. Besides, the plant has also been reported traditionally against fever, rheumatic arthritis, madness, liver ailments, dyspepsia, oedema, leishmaniasis, leprosy, dysmenorrhoea, sexual diseases etc. The plant is known to contain its major bioactive constituent aristolochic acid (AA) known for its anti-snake venom, abortifacient, antimicrobial and antioxidant properties. MATERIALS AND METHODS: This present work describes a validated, fast and reproducible high performance thin layer chromatography (HPTLC) method to estimate AA from the roots of 20 chemotypes of A. indica procured from 20 diverse geographical locations from the state of West Bengal, India. Further, an evidence-based approach was adopted to investigate the reported anti-venom activity of the aqueous extracts of the A. indica roots by assessing its phospholipase A2 (PLA2) inhibitory properties since PLA2 is a major component of many snake-venoms. Finally, the cytotoxicity and genotoxicity of the aqueous root extract of the Purulia (AI 1) chemotype were assessed at various concentrations using Allium cepa root meristematic cells. RESULTS: The highest amount of AA (7643.67 µg/g) was determined in the roots of A. indica chemotype collected from Purulia district followed by the chemotypes collected from Murshidabad, Jalpaiguri and Birbhum districts (7398.34, 7345.09 and 6809.97 µg/g respectively). This study not only determines AA in the plants to select pharmacologically elite chemotypes of A. indica, but it also identifies high AA producing A. indica for further domestication and propagation of the plants for pharmacological and industrial applications. The method was validated via analyzing inter-day and intra-day precision, repeatability, reproducibility, instrumental precision, limit of detection (LOD) and limit of quantification (LOQ) and specificity. Chemotypes with high AA content exhibited superior anti-PLA2 activity by selectively inhibiting human-group PLA2. Moreover, A. indica root extract significantly inhibited mitosis in Allium cepa root tips as a potent clastogen. CONCLUSIONS: The present quick, reproducible and validated HPTLC method provides an easy tool to determine AA in natural A. indica plant populations as well as in food and dietary supplements, a potential antivenin at one hand and a possible cause of aristolochic acid nephropathy (AAN) at another. Besides, the cytotoxic and mitotoxic properties of the root extracts should be used with caution especially for oral administration.

However, despite traditional claims, insufficient scientific validation for the treatment of insomnia, dementia, epilepsy, rheumatoid arthritis, asthma, spleen disorder, puerperal fever and leprosy, necessitate future investigations in this direction. It is also essential and critical to generate toxicological data and pharmacokinetics on human subjects so as to confirm its conceivable bio-active components in the body.

Mística, yerbas santas y solidaridad: memoria del cuidado no médico de la lepra en Agua de Dios / Mystique, Holy Herbs and Solidarity: Memory of Non-Medical Care of Leprosy in Agua de Dios / Mística, ervas santas e solidariedade: memória do cuidado no médico da lepra em Agua de Dios

Resumen Introducción: La representación social de la lepra como una enfermedad del pasado, el carácter local que la circunscribe a los sanatorios y el escaso contacto de trabajadores de la salud foráneos con la enfermedad hace pensar que el conocimiento sobre su cuidado ha circulado entre generaciones de una manera más o menos confinada. Ese saber que incorpora no solo conocimiento biomédico, sino expresiones en saberes, creencias, prácticas, relatos, los actores que las construyen y recrean y su relación compleja con las dinámicas de inserción en el territorio, se constituye hoy, en sí mismo, en un patrimonio vivo, que merece ser narrado. Desarrollo: Se parte de comprender la memoria de los cuidados no médicos de la lepra en Agua de Dios, por medio de un estudio etnográfico, cuyos resultados permiten proponer dos expresiones. La primera involucra a agentes de salud no médicos y su relación con los sujetos de cuidado; que muestra que el cuidado demanda no solo conocimiento científico, sino también disposiciones particulares de los sujetos, como capacidad de escucha, observación, paciencia y trascendencia, acompañadas de un posicionamiento y negociación cotidianos en el territorio. La segunda está compuesta por las alternativas de cuidado intermediadas por otros agentes con saberes autorizados, que agrupan una amplia farmacopea relacionada con el uso de plantas medicinales, referencias a curanderos y prácticas solidarias de tutoría entre pacientes y relaciones de su bienestar con el medio ambiente. Conclusiones: Todas estas expresiones de cuidado desafían los discursos y prácticas canónicas de la biomedicina alrededor de esta enfermedad.

Abstract Introduction: The social representation of leprosy as a disease from the past, its local character that circumscribes it to the sanatoria, and the scarce contact of health workers with it suggest that the knowledge about its care has circulated between generations more or less confined. This confined knowledge, which incorporates not only biomedical knowledge but also expressions in knowledge, beliefs, practices, stories, the actors that construct and recreate them and their complex relationship with the dynamics of insertion in the territory in a living heritage, deserves to be narrated. Development: We begin by understanding the memory of the non-medical care of leprosy in Agua de Dios, through an ethnographic study, whose results allow us to propose two expressions of these. The first one, involving the non-medical health agents (especially nurses) and its relationship with care subjects, showed that this demands particular dispositions from the subjects as listening ability, observation, patience, and transcendence, accompanied by daily positioning and negotiation in the territory. The second is the care alternatives mediated by other agents with authorized knowledge that group a wide pharmacopeia related to the use of medicinal plants; references to healers and solidarity practices of mentoring between patients and relationships of their well-being with the environment. Conclusions: All these expressions of care challenge the discourses and canonical practices of biomedicine around this disease.

Resumo Introdução: A representação social da lepra como uma doença do passado, seu carácter local que a circunscreve aos sanatórios, e o escasso contato de trabalhadores da saúde estrangeiros com a doença, faz pensar que o conhecimento sobre seu cuidado, tem circulado entre gerações de uma maneira mais ou menos confinada. Esse saber "confinado", que incorpora não só conhecimento biomédico, senão expressões em saberes, crenças, práticas, relatos, os atores que as constroem e recriam e sua relação complexa com as dinâmicas de inserção no território, constitui-se hoje em si mesmo, em um patrimônio vivo, que merece ser narrado. Desenvolvimento: Partimos de compreender a memória dos cuidados não médicos da lepra em Agua de Dios, através de um estudo etnográfico, cujos resultados nos permitem propor duas expressões destes. A primeira que envolve agentes de saúde não médicos e sua relação com os sujeitos de cuidado, mostrou que esta demanda não só conhecimento "científico", mas também disposições particulares dos sujeitos como capacidade de escuta, observação, paciência e transcendência, acompanhadas de um posicionamento e negociação cotidianos no território. A segunda a constituem as alternativas de cuidado intermediadas por outros agentes com saberes "autorizados" que agrupam uma ampla farmacopeia relacionada com o uso de plantas medicinais; referências a curandeiros e práticas solidárias de tutoria entre pacientes e relações de seu bem-estar com o meio ambiente. Conclusões: Todas estas expressões de cuidado, desafiam os discursos e práticas canónicas da biomedicina ao redor desta doença.

The Medicinal Usage and Restriction of Ginseng in Britain and America, 1660-1900.

This article demonstrates the medicinal usage of ginseng in the West from 1660 to 1914. Asian[Korea] ginseng was first introduced into England in the early 17th century, and North American ginseng was found in the early 18th century. Starting from the late 17th century doctors prescribed ginseng to cure many different kinds of ailments and disease such as: fatigue general lethargy, fever, torpidity, trembling in the joints, nervous disorder, laughing and crying hysteria, scurvy, spermatic vessel infection, jaundice, leprosy, dry gripes and constipation, strangury, yellow fever, dysentery, infertility and addictions of alcohol, opium and tobacco, etc. In the mid-18th century Materia Medica began to specify medicinal properties of ginseng and the patent medicines containing ginseng were widely circulated. However, starting in the late 18th century the medicinal properties of ginseng began to be disparaged and major pharmacopoeias removed ginseng from their contents. The reform of the pharmacopoeia, influenced by Linnaeus in botany and Lavoisier in chemistry, introduced nomenclature that emphasized identifying ingredients and active constituents. Western medicine at this period, however, failed to identify and to extract the active constituents of ginseng. Apart from the technical underdevelopment of the period, the medical discourses reveal that the so-called chemical experiment of ginseng were conducted with unqualified materials and without proper differentiation of various species of ginseng.

It is widely distributed in tropical and subtropical regions of the world and has therapeutic potential against many diseases such as diabetes, anaemia, stomatitis, leprosy, cancer and infectious diseases. Neolamarckia cadamba has historical existence in India and it is mentioned in mythical stories. There are several reports on medicinal values of root, bark and leaves of N. cadamba; but the literature on its fruits is scanty. Therefore, the present review aims to provide updated comprehensive information on the phytochemistry and pharmacological properties of different parts of N. cadamba tree with special reference to its fruit, in order to open new perspectives for future food and pharmacological research. MATERIALS AND METHODS: A literature search was performed on N. cadamba using ethnobotanical textbooks, published articles in peer-reviewed journals, unpublished materials, government survey reports and scientific databases such as Pubmed, Scopus, Web of Science, Science Direct, Google Scholar and other web search engines (Google, Yahoo). The Plant List, International Plant Name Index and Kew Botanical Garden Plant name databases were used to validate the scientific names. RESULTS AND DISCUSSION: Neolamarckia cadamba is one of the economically important trees, which is being exploited for paper, pulp and wood industry. In folk medicine, various parts of N. cadamba are used in the treatment of various ailments such as fever, uterine complaints, blood diseases, skin diseases, tumour, anaemia, eye inflammation and diarrhoea. Other reported uses of N. cadamba include antihepatotoxic, antimalarial, analgesic, anti-inflammatory, antipyretic, diuretic and laxative. Various phytochemicals such as cadambine and its derivatives (dihydrocadambine and isodihydrocadambine) and indole alkaloids (Neolamarckines) were isolated from the leaves; whereas the presence of quinovic acid derivatives have been reported in the bark of N. cadamba. CONCLUSION: The present review compiles information on an ethnopharmacologically useful plant N. cadamba. Bioactive compounds responsible for its various medicinal properties and their effects at the molecular level need to be investigated in more detail. Furthermore, the detailed study of toxicity and pharmacological properties of extracts as well as molecules in N. cadamba is required to confirm the ethnomedicinal claims of N. cadamba for food and pharmaceutical applications.

Ethnomedicinal plants used to treat skin diseases by Tharu community of district Udham Singh Nagar, Uttarakhand, India.

ETHNOPHARMACOLOGICAL RELEVANCE: Tharu community is the largest primitive indigenous community of the Uttarakhand, India. In this article we have scientifically enumerated medicinal plants and herbal preparations used by the Tharu community to treat various skin diseases, and discussed dermatological properties of these plants in the light of previous ethnomedicinal, microbiological, pharmacological, toxicological, phytochemical and clinical studies. MATERIALS AND METHODS: Ethnomedicinal survey was conducted in different villages of Tharu community located in district Udham Singh Nagar, Uttarakhand, India. Ethnomedicinal information on plants used to treat various skin diseases was collected from 122 individuals (93 males and 29 females), including 35 experienced herbal practitioners and 87 local villagers. For each of the recorded plant species the use value (UV) and fidelity level (FL) was calculated. The informant consensus factor (Fic) was also calculated to find out the homogeneity in the information given by the informants. RESULTS: A total of 90 plant species belonging to 86 genera and 48 families were used by the Tharu community to treat various skin diseases viz., wounds (38 spp.), boils (32 spp.), cuts (18 spp.), leprosy (11 spp.), eczema (10 spp.), itching (7 spp.), ringworm (5 spp.), burns (4 spp.), leucoderma (4 spp.), cracked heels (2 spp.), dandruff (3 spp.), body infection (2 spp.), chilblains (2 spp.), hair fall (2 spp.) and toes infection (2 spp.). Information on botanical name, family, vernacular name, ailments treated, mode and dose of herbal preparations, UV and FL values are provided for each of the recorded species. According to UV value most preferred plant species used to treat skin diseases by Tharu community was Ricinus communis L. followed by Tridax procumbens (L.) L., Azadirachta indica A. Juss., Ageratum conyzoides and Allium cepa L. CONCLUSIONS: The present study has revealed significant information on various medicinal plants used to treat skin diseases by Tharu community. Literature review has confirmed most of the claims made by the Tharu community regarding treatment of various skin diseases by the reported plants. The literature review has also revealed that products from very few of the reported plants are available in market, while most of the reported plants are still under preclinical or clinical trials. There are various known phytochemicals, and antibiotic, antibacterial, antiviral and antifungal agents present in these plants which may be synthesized or transformed to make pharmaceuticals. Some of the reported plants have shown promising results in preclinical trails and there is a need of clinical trials to see their safety and efficacy in treating various skin diseases. These plants may be targeted for development of new medicines, ointments or drugs for the treatment of skin diseases. However further toxicological, preclinical and clinical studies are needed to validate claims about little worked out plant species reported in the present study viz., Sida cordata (Burm. F.) Borss. Waalk., Millettia extensa (Benth.) Baker, Caesulia axillaris Roxb., Ehretia laevis Roxb., Vanda tessellate (Roxb.) Hook. Ex G.Don. and Eualaliopsis binata (Retz.) C.E. Hubb. Further studies on these plants are recommended to assess their potential in development of new skin care products.
