“…In the early studies, we reported the list of plants used by the Karens for various illnesses (Chander et al, 2015) and we selected nine plants routinely used by the karens. Methanol extracts of Z. spectabilis, S. wallichiana and C. pulcherrima showed the antimalarial activity and no previous reports available on the antimalarial properties of these medicinal plants in the literature.…”

BJP IntroductionAndaman and Nicobar Islands, a union territory of India, has been historically known for high malaria transmission. The tropical climate prevailing throughout the year provides an ideal environment for mosquito proliferation and breeding in Nicobar group of islands (Manimunda et al., 2011). Entire land mass in the island has a network of creeks which results in ideal brackish water habitats for the breeding of Anopheles sundaicus, the predominant vector of malaria in Andaman and Nicobar Islands (Krishnamoorthy et al., 2005).Malaria prevalence has increased alarmingly in past few years due to the development of drug resistance by Plasmodium falciparum (Parzy et al., 1997). Therefore, new and more effective therapeutic agents are urgently required to overcome the problem of malaria.The Karen tribe is a lesser-known community in these Islands, settled in Mayabunder, North and Middle Andaman District. Karen derives from the word 'Kavin'as British called them, while they called themselves as Pwakanyaw, the quiet and easy going people, hailing from Henzada, Pathe and Nachaon areas of Pegu district in Western Myanmar (Oberai, 2000). Presently they inhabit three villages depending on agriculture and fishing for livelihood. Most of them depend on traditional medicine, though modern medicine had increased rapidly during recent times (Chander et al., 2015). As a part of the ongoing studies documented their traditional treatment practices and collected plants which were reported to be efficacious in the treatment of traditional medicine system.In the present study, nine of these plants were subjected to in vitro antimalarial activity against P. falciparum chloroquine-sensitive (MRC-2) isolate. Materials and Methods Plant materialsNine plants were selected for evaluation on the basis of their ethnomedicinal histories. The names of these AbstractThe aim of this study was to assess the antimalarial activity of nine medicinal plants used by Karens of Andaman and Nicobar Islands, against Plasmodium falciparum chloroquine-sensitive MRC-2 isolate. The methanol extracts were obtained by cold percolation method and in vitro antimalarial activity was assessed using M-III method. The results indicated that out of nine plant species tested, four plants, viz., Z. spectabilis, S. wallichiana, C. pulcherrima and Amomum sp. demonstrated significant antimalarial activity (50% inhibitory concentration values were 5.5 ± 0.7, 12.0 ± 2.5, 14.6 ± 1.3 and 37.3 ± 2.5 μg/mL respectively) with no toxicity effect on erythrocytes.Article Info

“…The aqueous extraction method in this study found effective antibacterial property but poor antifungal property with C. cajan [33] was stated that C. cajan is more active against fungus A. niger and showed 48 components in the GC-MS spectrum [34]. Various studies in the past have demonstrated a major component in pigeon pea leaves that have potential benefits to human health with flavonoids and [35,36] including treatment of diabetes and jaundice [37,38,39]. showed antibacterial properties in two of the three main components of the oils identified i.e.…”

Aims: Medicinal plants have been a fundamental part of the human health since existence. Guyana is surrounded high in the green shoulder of northern South America and shares Amazon River and Amazon Forest. South American population use plant extracts obtained from traditional medicinal plants as treatment for many infectious diseases. The study aimed to estimate antifungal property and chemical composition of the three medicinal plants Cymbopogon citratus (lemongrass), Cajanus cajan (pigeon pea) and Plectranthus amboinicus (thick leaf thyme) leaves collected from the coastal areas of Guyana. Study Design: Experiment based study. Place and Duration of Study: Plants were gathered along the East Coast of Guyana and identified at the Biodiversity Center, University of Guyana, Georgetown, Guyana between January 2017- May 2017. Methodology: Phytochemical extraction was conducted using the soxhlet and rotovap apparatus and an aqueous extraction method. Data analysis of the study was done using R-Studio Program for statistical computing and graphics. A Tukey test was done along with ANOVA and Boxplots. Results: Qualitative analysis of phytochemicals was carried out and the presence of terpenoids, steroids, glycoside, alkaloid, tannins and saponins were positive in some plants. Antifungal activity was tested using the poisoned food and well diffusion techniques. Conclusion: In conclusion, C. cajan showed significant zones of inhibition using a well diffusion technique whereas hexane extract showed significant inhibition with poisoned food technique.

“…Some terrestrial plants are considered medicinal owing to their analgesic properties. Some of the most commonly used analgesics from food plant sources are moringa/drumstick ( Moringa oleifera ), guava ( Psidium guajava ), turmeric ( Curcuma longa ), and ginger ( Zingiber officinale ) for abdominal pain; potato ( Solanum tuberosum ) for headache; carrot ( Daucus carota ) for painful urination; and celery ( Apium graveolens ) for labor and joint pain [ 13 , 15 - 18 ].…”

: Pain is a distressing but fundamental manifestation that prepares the body for potentially detrimental stimuli while ensuring its protection. Plant and animal products have traditionally been used to relieve pain for centuries. However, no attempt has been made to compile a single report of plant and animal products possessing analgesic properties. This review enadeavours to recover data from published articles to establish a collective literature review on folk remedies from plant and animal sources used as analgesics and in the treatment of pain-related conditions, identifying gaps in existing knowledge and future works. Relevant information was systematically retrieved using the PRISMA method. In this review, in total, 209 plants were found to be either used raw or prepared by decoctions or maceration. Administration was either oral or topical, and they were predominantly used in Asian countries. In vivo studies of plants with analgesic properties, which were tested using different methods including acetic-induced writhing test, hotplate test, tail-flick test, and formalin-induced pain test, were compiled. Animal products with analgesic properties were obtained mainly from compounds present in venom; their bioactive compounds were also identified. In the literature search, certain gaps were noted, which could be reviewed in future studies. For instance, there was a disparity of information regarding the traditional uses of medicinal plants. In this review, an attempt was made to critically assess and describe the pharmacological properties and bioactive composition of indigenous plants, some animal species, and animal venom by scrutinizing databases and looking for published articles. Therefore, it can be concluded that the compounds obtained from these sources can serve as important ingredients in therapeutic agents to alleviate pain once their limitations are assessed and improved upon. In the literature search, certain gaps were noted, which could be reviewed in future studies.
