Medicinal Uses of Poisonous Plant - A Brief Review

A poisonous plant is defined as a plant that when touched or ingested in sufficient quantity can be harmful or fatal. Many plants are harmful to people when consumed or through skin contact with plant chemicals. Poisonous medicinal herbs are used to treat a variety of illnesses, including diabetes, cancer, infection, and fungal growth. According to the review, numerous phytochemical components that have diuretic, purgative, laxative, anti-allergic, and other significant therapeutic effects have been identified from a variety of medicinal plants. If utilized appropriately, poison can be life-giving, calming to the three Doshas, encouraging, and regenerating. The poisonous plants categorized in Visha and Upvisha in Ayurveda texts. Agadtantra is an important branch of Astanga Ayurveda. Importance of this branch has been described in our Vedas, Epics, and Samhita. Proper description, classification, clinical features, and management of any kind of Visha has been described in this branch. Name of some poisonous plants are Dhatura, Vatsanabha, Bhallataka, Bhanga, Kuchala, Vacha and Gunja etc. Shodhana process is the only bridge between Visha and Aushadhi. Shodhana is the process by which physical, chemical and natural impurities are removed. It will intensify the potency, effectiveness of drug, nullify the toxicity. The aim of this review article is to provide a brief overview of the numerous medicinal uses of some poisonous plant.

Study of Medicinal Plants Found in Yamkeshwar Block District Pauri, and their Therapeutic Uses, Uttarakhand, India with reference to Bhavaprakash Nighantu: A Review

The prolific plant diversity of Uttarakhand hills has provided an initial lead to the local people to look for various plant species for the purpose of food, medicine, spices and perfumes. Medicinal plants found in Pauri district at Yamkeshwar block Uttarakhand, India have resulted in the documentation of medicinal, aromatic and spice plant species. These species were distributed over various life forms, like tree, shrub and herbaceous forms. The plants species were collected and arranged in their botanical name family, Sanskrit name, local name and their habit pattern. The leaves root, stem bark and whole plants were the mostly used. The traditional knowledge of medicinal plants gathered from local healers at Yamkeshwar block transmitted orally one generation to another generation but not documented. Now new generation is not interested in traditional knowledge of medicinal plants due to modernization, so there is an urgent need to document ethnomedicinal plants before the knowledge become extinct. Conservation and sustainable utilization of these valuable medicinal plant species is essential to protect the traditional knowledge regarding plants and plant based healing practices. In this article made an effort to document such information, especially the plants found in that region and use of plants for medicine, and made an effort to enlist the medicinal plants mentioned in Bhavaprakash Nighantu.

Diversity, Ethnobotanical Potential and Sustainability Assessment of Plants Used by Traditional Healers to Treat Cancer in Boyo Division, North-West Region, Cameroon

Aims: Cancer is the second leading cause of death globally. Therefore, the knowledge on medicinal plants used to cure human cancer could be of great importance for their widespread use and scientific validation. The present study records information on anticancer plants in Boyo Division, in the western highland of Cameroon. Methods: Thirty traditional healers, were interviewed to document their know-how on the type of human cancer allegedly cured, the plant species used as well as their use pattern. Guided field walks were made to the collection sites for plant and its habitat characterization as well as herbarium voucher collection. Ethnobotanical quantitative tools were used to analyze and summarize collected data. Sustainability of harvest was assessed using a vulnerability index based on seven parameters. Results: A total of 25 medicinal plants cited were identified as belonging to 13 families and 23 genera. The most represented families were Asteraceae (28%), Lamiaceae (16%), Fabaceae (12%) and Acanthaceae (8%). Out of the seven categories of cancer diseases reported, the highest number of plants species were reported to treat stomach, pancreas, liver, skin and breast cancers, with informant consensus factor (ICF) ranging from 0.79 to 0.82. Leaves (60%) and bark (20%) were the major plant parts used mostly in form of decoction (45.45%) and concoction (38.18%). The result of Relative frequency citations (RFCs) revealed that 9 of the 25 plants species cited were the most frequently used with fidelity levels ranging from 92% (Geniosporum rotundifolium and Ocimum tenuiflorum Aframomum melegueta and Entada abyssinica) to 100% (Coleus blumei, Ocimum gratissimum, Eremomastax speciosa, and Dichrocephala integrifolia). Six species were assessed as vulnerable (Vi ≥ 2), while two species were rated as highly vulnerable namely G. rotundifolium (Vi = 2.71) and E. abyssinica (Vi = 2.85). Conclusion: New traditionally effective anticancer plants were identified in the present study, some of which were already vulnerable for exploitation in their actual habitat. Plants with high ICF, RFCs and FL values should be subjected to further phytochemical and pharmacological investigations for scientific validation while those with high Vulnerability index should be recommended for participatory domestication by the main users.

Ethnobotanical profiling of the medicinal flora of Kotli, Azad Jammu and Kashmir, Pakistan: Empirical reflections on multinomial logit specifications

Objective To report the indigenous people's uses of plants from a multidimensional perspective in a remote area where strong ethnobotanical cultural practices prevail. Methods An ethnobotanical survey was conducted in the field during 2014–2016. Ethnobotanical data were gathered from 182 informants through oral interviews and semi-structured questionnaires. The distribution of plants was explored using both descriptive and graphical methods. Further, a Multinomial Logit Specification was applied to find out the probability of the occurrence of diverse utilization of plants in multipurpose domains. Results The study identified 202 plant species distributed among 71 families and 156 genera. Ethnobotanical data indicate that there are more medicinal (36.96%) uses of plants as compared to all other use categories. The output from the Multinomial Logit Specifications (MLS) model reveals that perennial and non-woody plants are exploited more for medicinal and food uses than annual and woody plants. In the context of ethnomedicinal uses, aerial plant parts particularly leaves are more extensively used for the preparation of herbal recipes as compared to underground parts. Conclusions The results of the study emphasize the need to create awareness among the local communities about the conservation status of plant species in order to maintain a sustainable resource of plant-derived materials into the future. The novel econometric approach employed in this study adds a new insightful methodology to the existing body of literature in the field of ethnobotany. We strongly recommend conservation measures, alongside phytochemical and pharmacological studies on the useful plant species identified in this study in order to ensure their sustainable and effective utilization.

Annona muricata: Is the natural therapy to most disease conditions including cancer growing in our backyard? A systematic review of its research history and future prospects

Annona muricata (A. muricata) is a tropical plant species belonging to family Annonaceae and known for its many medicinal uses. This review focuses on the research history of its traditional uses, phytochemicals, pharmacological activities, toxicological aspects of the extracts and isolated compounds, as well as the in vitro propagation studies with the objective of stimulating further studies on this plant for human consumption and treatment. A. muricata extracts have been identified in tropical regions to traditionally treat diverse conditions ranging from fever to diabetes and cancer. More than 200 chemical compounds have been identified and isolated from this plant, the most important being alkaloids, phenols and acetogenins. Using in vitro studies, its extracts and phytochemicals have been characterized as antioxidant, anti-microbial, anti-inflammatory, insecticidal, larvicidal, and cytotoxic to cancer cells. In vivo studies have revealed anxiolytic, anti-stress, anti-inflammatory, immunomodulatory, antimalarial, antidepressant, gastro protective, wound healing, hepato-protective, hypoglycemic, anticancer and anti-tumoral activities. In silico studies have also been reported. In addition, clinical studies support the hypoglycemic as well as some anticancer activities. Mechanisms of action of some pharmacological activities have been elucidated. However, some phytochemical compounds isolated from A. muricata have shown a neurotoxic effect in vitro and in vivo, and therefore, these crude extracts and isolated compounds need to be further investigated to define the magnitude of the effects, optimal dosage, and mechanisms of action, long-term safety, and potential side effects. Additionally, more clinical studies are necessary to support the therapeutic potential of this plant. Some studies were also found to have successfully regenerated the plant in vitro, but with limited success. The reported toxicity notwithstanding, A. muricata extracts seem to be some of the safest and promising therapeutic agents of the 21st century and beyond that need to be studied further for better medicinal formulations and diseases management.

Biotechnological intervention in betelvine (Piper betle L.): A review on recent advances and future prospects

Betelvine (Piper betle L.) is cultivated for its deep green heart shaped leaf for (15–20) million Indian and 2 billion foreign consumers annually. The crop provides Rs (6 000–7 000) million of national income per year and at the same time leaves worth Rs (30–40) million is exported to other countries. The leaves are not only used directly for chewing purposes but also possesses antioxidant, anti-inflammatory, anti-apoptotic, anti-cancer and anti-microbial properties. Besides, the leaves also contain eugenol rich essential oil (1%–3%) which is the source for medicine, stimulant, antiseptic, tonic and other ayurvedic formulations. The essential oil also contains chavibetol, caryophyllene and methyl eugenol which are the potent source for preparation in ayurvedic medicine and herbal products. Cost of betelvine essential oil is 10$ per 5 mL. In spite of its great economical and medicinal importance betelvine is still neglected by the researchers for proper characterization and authentication for selection of elite landraces. Lack of awareness among people, use of same planting material for many generations, existing of many synonyms for a single landraces, no proper characterization of available landraces are some of the significant constraints for its commercialization. Our review endeavours a complete advance in the research on betelvine, existing lacunae for its proper characterization and commercial cultivation. It also attempts to provide a comprehensive account on biotechnological interventions made in betelvine aimed at complementing conventional programmes for improvement of this nutraceutically important cash crop.

Syzygium cumini (L.) Skeels：A review of its phytochemical constituents and traditional uses

Syzygium cumini (S. cumini) (L.) Skeels (jambolan) is one of the widely used medicinal plants in the treatment of various diseases in particular diabetes. The present review has been primed to describe the existing data on the information on botany, phytochemical constituents, traditional uses and pharmacological actions of S. cumini (L.) Skeels (jambolan). Electronic database search was conducted with the search terms of Eugenia jambolana, S. cumini, jambolan, common plum and java plum. The plant has been viewed as an antidiabetic plant since it became commercially available several decades ago. During last four decades, numerous folk medicine and scientific reports on the antidiabetic effects of this plant have been cited in the literature. The plant is rich in compounds containing anthocyanins, glucoside, ellagic acid, isoquercetin, kaemferol and myrecetin. The seeds are claimed to contain alkaloid, jambosine, and glycoside jambolin or antimellin, which halts the diastatic conversion of starch into sugar. The vast number of literatures found in the database revealed that the extracts of different parts of jambolan showed significant pharmacological actions. We suggest that there is a need for further investigation to isolate active principles which confer the pharmacological action. Hence identification of such active compounds is useful for producing safer drugs in the treatment of various ailments including diabetes.
