Abstract
BACKGROUND OBJECTIVES Shompens are one of the two mongoloid tribes of Nicobar district. There is little information about their recent health status since the last survey which was conducted in 1998. Hence, a comprehensive health and nutritional survey was conducted in March 2017 to assess the changes. The survey was carried out by a joint team of various organizations including the ICMR-Regional Medical Research Centre and Tribal Welfare and Health Department both located in Port Blair. METHODS A detailed health and nutrition survey of the Shompen community was planned by deputing a field research team. The survey included demographic data, anthropometric data, clinical examination, screening for the markers of infectious diseases, respiratory pathogens, tuberculosis and haemoglobinopathies. RESULTS About half of the Shompen adults (both males and females) had a body mass index (BMI) of ≥23. However, Shompen children had a good nutritional status with no child suffering from undernutrition. As per BMI for age, none of the children <5 yr were under-nourished, while in the 5-17 yr group, 12 per cent of children were undernourished. Anaemia prevalence was about 48.3 per cent, with 54 per cent prevalence in females and 43.8 per cent in males. Fungal infection of the skin, acute respiratory infection and abdominal pain were the common morbidities observed. None had active pulmonary tuberculosis. Of 38 Shompens screened for IgG (immunoglobulin G) antibodies, 42.1 and 18.4 per cent were positive for measles and rubella, respectively. Seroprevalence of Leptospira was 35.5 per cent. The prevalence of hypertension was 13.2 per cent, whereas another 28.9 per cent were pre-hypertensive. INTERPRETATION CONCLUSIONS The population structure of the Shompen is not skewed and under nutrition was not widely prevalent among the children of <5 yr. The other positive observations were the absence of malaria, filariasis and dengue. However, there was natural infection of measles and rubella. Fungal skin infection and intestinal parasitic infestations were widely prevalent. Although cardiovascular risk profile was low, there were signs of emerging risk of over-weight, hypertension and dyslipidaemia. These together with the high prevalence of smokeless tobacco use may have a serious effect on the cardiovascular disease susceptibility of the Shompen population in the future.

Abstract
Background & objectives: Tribal people often depend on herbal medicines and the traditional knowledge practitioners (TKPs) serve as their healthcare service providers. This study was an attempt to document the use of medicinal plants by the Nicobarese of Nancowry group of Islands. Methods: Field survey was conducted in all the five inhabited Islands of the Nancowry group of Islands. All the TKPs were interviewed with a questionnaire-guided ethnomedicinal survey protocol. Voucher specimens of all the cited plants (botanic species) were collected and a Community Biodiversity Register of Nicobarese of Nancowry was prepared. Results: A total of 77 TKPs were identified, who together were using 132 medicinal plant species belonging to 113 genera and 62 families. The TKPs were treating a total of 43 ailments. Seven endemic and three rare plant species were recorded. The most common plant part used was leaves. Remedies were usually prepared using water as the excipient. Routes for administration of medicinal plant preparations were oral, topical and others. The information collected from the TKPs were collated in the form of Community Biodiversity Registers. Interpretation & conclusions: The present survey shows that the medicinal plants play a pivotal role in the healthcare of the Nicobarese tribe of Nancowry group of Islands. Efforts to document the medicinal plant species and the formulations used by them are necessary to prevent the loss of this precious knowledge.

Abstract
BACKGROUND This study is an attempt to document the medicinal plants used by the tribal community of Little Nicobar Island. Despite modern healthcare facilities, tribals often consume medicinal herbs, with traditional knowledge practitioners (TKPs) serving as local medical experts. OBJECTIVES The aim is to conduct an ethnomedicinal survey among the Nicobarese, whose medicinal practices are yet to be documented. METHODS Field research was conducted in all five villages of Little Nicobar Island, situated in the southernmost part of the Andaman and Nicobar Archipelago, during 2012-2013. Seven TKPs were interviewed using a questionnaire-guided ethnomedicinal survey protocol. The data obtained were analyzed using the informant consensus factor (ICF) and use value. Voucher specimens of all the cited plant species were deposited at the Regional Medical Research Centre (Indian Council of Medical Research), Port Blair. RESULTS Uses of 34 medicinal plant species, belonging to 23 families encompassing 32 genera, were recorded during the survey. These 34 species are employed to treat a total of 16 ailments. The highest ICF (1.00) was obtained for respiratory diseases. The Euphorbiaceae family exhibited the highest number of citations, and plants with the highest use values were Glochidion calocarpum Kurz, Senna occidentalis (L.) Link, Ocimum tenuiflorum L., and Passiflora suberosa L. Of the medicinal plants reported, the most common growth form was herbs. Remedies were generally prepared using water. The medicinal plant preparations were administered topically or orally. INTERPRETATION AND CONCLUSIONS Traditional knowledge of herbal medicines is handed down orally through generations. These plants attained a significant role under the healthcare of the Nicobarese residing in Little Nicobar Island. Efforts to ensure their documentation are necessary in order to prevent its loss, either because of natural calamities or lack of interest among younger generations in carrying out their tradition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This study documents the use of medicinal plants by Karens of Middle Andaman, of the Andaman and Nicobar Islands. In spite of the availability of modern medicines, Karens preferred herbal remedies provided by the Traditional Knowledge Practitioners (TKPs), who served as their healers. Hence, the aim of this study was to collect information from TKPs and determine the significance of plants utilized for medicinal purposes. The informant consensus factor (ICF) in relation to medicinal plants used was also estimated and analysed. MATERIALS AND METHODS Field research was conducted in three villages of Middle Andaman, inhabited by Karens, during October 2010 - February 2013. TKPs were interviewed with a questionnaire-guided ethno-medical survey protocol. The data obtained were analysed using the informant consensus factor (ICF) and use value (UV). Voucher specimens of all the cited plants were deposited at Regional Medical Research Centre (ICMR), Port Blair. RESULTS Use of 78 medicinal plant species belonging to 71 genera encompassing 48 families was recorded during the survey. These plants were used to treat 38 different ailments, and divided into ten categories of use. The highest ICF value (0.79) was observed for infections and infestations. The Zingiberaceae and Fabaceae families exhibited the highest number of species, and the plants with the highest use values were Typha angustifolia L., Millingtonia hortensis L. f. and Piper betle L. The most common growth form observed were herbs (42%). Among the several plant parts used, leaves were mostly preferred for preparation of medicines. Water was the main excipient used for mixing the herbs. CONCLUSIONS This study documents the use of medicinal plants by Karens of the Andaman and Nicobar Islands. Phytochemical and pharmacological aspects of these plants need to be studied, to confirm their efficacy and safety, and determine their potential use in modern medicine.
