Integration of traditional herbal medicines among the indigenous communities in Thiruvarur District of Tamil Nadu, India.

ABSTRACT: BACKGROUND:Ethnobotanical studies are recognized as effective methods of finding locally important plants for discovery of crude drugs. Siddha medicinal system is prevailed in south Indian states principally in Tamil Nadu and gaining recognition as alternative medicine among the indigenous communities for their primary healthcare needs. OBJECTIVES:The study was aimed to explore and document folk medicinal plant knowledge among the local people in Puliyankudi village of Thiruvarur District, Tamil Nadu, India. MATERIALS AND METHODS:An ethnobotanical study was carried out during February 2016 to January 2017 among the local people in study area. Traditional healers, traders, local vendors and local people who are practicing herbal medicines were approached for documentation of folk medicinal uses. Acquired results were further analyzed with descriptive statistical methods such as use value (UV) and informant consensus factor (ICF). RESULTS:During the survey, a total 116 plant species from 49 families and 103 genera were recorded to treat 73 types of ailments. Among the plant parts used for preparation of medicine, leaves (73 reports) are often used and predominant method of preparation of medicine is paste (56 reports). Limonia acidissima was reported by all the interviewed informants with an UV of 0.98 and kidney problems have highest ICF value of 0.91. CONCLUSION:Plants with highest use values in the study indicates possible occurrence of valuable metabolites and should be investigated for associated pharmacological activities which leads to development of potential new drugs to treat various ailments.

Project description:BackgroundMedicinal properties of the food species are one of the poorly documented and important areas of ethnopharmacology. The present survey quantitatively documented the medicinal foods prescribed by the non-institutionally trained siddha practitioners of Tiruvallur district of Tamil Nadu.MethodsField work was carried out between December 2014 and April 2017 using a questionnaire. The illnesses mentioned by the informants were grouped as illness categories on the basis of emic perceptions. Sufficiency of sampling of this survey was assessed by plotting the cumulative number of UR and Shannon-Wiener's index. The indices such as informant consensus factor (FIC), Index of Agreement on Remedies (IAR), and Cultural Food Significance Index (CFSI) were calculated.ResultsThis study documented 165 medicinal foods used by 82 non-institutionally trained siddha practitioners of Tiruvallur district, and 73.93% of these preparations were plant based. Among the animal taxa, 82.05% were represented by fish taxa. The illness category gastrointestinal ailments is the majorly cited illness category treated with plant-based formulations. The illness categories viz., gastrointestinal ailments, hemorrhoids, and neural ailments had high consensus under the group of plant-based medicinal foods. In animal-based medicinal foods, kapha ailments had gained 23.07% of UR. The illness categories such as bone fractures, male reproductive ailments, blood ailments, and anabolic had high FIC values.ConclusionsDeeper studies on different dietary cultures of India may help to derive better interpretations on food-medicine continuum. This study identified some important claims such as the use of citron, pomegranate and Solanum americanum (gastrointestinal ailments), Abutilon indicum, onions and elephant foot yam (hemorrhoids), Boerhavia diffusa (urinary ailments), Moringa oleifera (anemia), Aloe vera (gynecological ailments), Eclipta prostrata (liver ailments), ivy gourd (diabetes), citron (hypertension), Centella asiatica (psychological ailments), spade nose shark (lactogogue), reticulate whipray (wheezing and bronchitis), Katelysia opima (impotence), Indian squid (anemia), and Indian oil sardine (anabolic). More studies on these claims will help identify novel functional foods to add to the field of medical nutrition therapy, with traditional brand identity. Robust studies on the documentation of the traditional knowledge on marine resources will yield a good database for various stakeholders and policy makers.

Project description:India retains the world's largest burden of anemia despite decades of economic growth and anemia prevention programming. Accurate screening and estimates of anemia prevalence are critical for successful anemia control. Evidence is mixed on the performance of HemoCue, a point-of-care testing device most widely used for large-scale surveys. The use of dried blood spots (DBS) to assess hemoglobin (Hb) concentration is a potential alternative, particularly in field settings. The objective of this study is to assess Hb measurement agreement between capillary HemoCue and DBS among two age groups, children 6-59 months and females age 12-40 years. We analyzed data from the baseline round of a cluster randomized rice fortification intervention in Cuddalore district of Tamil Nadu, India. Capillary blood was collected from a subset of participants for Hb assessment by HemoCue 301 and DBS methods. We calculated Lin's concordance correlation coefficient, and tested bias by conducting paired t-tests of Hb concentration. Independence of the bias and Hb magnitude was examined visually using Bland-Altman plots and statistically tested by Pearson's correlation. We assessed differences in anemia classification using McNemar's test of marginal homogeneity. Concordance between HemoCue and DBS Hb measures was moderate for both children 6-59 months (ρc = 0.67; 95% CI 0.65, 0.71) and females 12-40 years (ρc = 0.67: 95% CI 0.64, 0.69). HemoCue measures were on average 0.06 g/dL higher than DBS for children (95% CI 0.002, 0.12; p = 0.043) and 0.29 g/dL lower than DBS for females (95% CI - 0.34, - 0.23; p < 0.0001). 50% and 56% of children were classified as anemic according to HemoCue and DBS, respectively (p < 0.0001). 55% and 47% of females were classified as anemic according to HemoCue and DBS, respectively (p < 0.0001). There is moderate statistical agreement of Hb concentration between HemoCue and DBS for both age groups. The choice of Hb assessment method has important implications for individual anemia diagnosis and population prevalence estimates. Further research is required to understand factors that influence the accuracy and reliability of DBS as a methodology for Hb assessment.
