Swertia is one of the most widely traded genus of 150 species, many of which are used in Ayurvedic, Chinese, Tibetan and traditional medicine. Swertia herb is mostly traded and exported in dried or in extract forms. In this present study, a microwave-assisted extraction (MAE) method coupled with simultaneous quantification of swertiamarin, amarogentin, and mangiferin from different species of Swertia using high performance thin layer chromatography (HPTLC) was developed. A three-level factor Box-Behken statistical design was used for optimization, where microwave power, irradiation time, and solvent-to-solid ratio were used as independent variables whereas swertiamarin, amarogentin and mangiferin were used as the dependent variables. Densitometric-HPTLC method was developed for the simultaneous estimation of swertiamarin, amarogentin, and mangiferin using mobile phase of ethyl acetate: acetic acid glacial: formic acid: water (10:1.2:1.2:2.7 v/v/v/v) and stationary phase as silica gel F-254 HPTLC plate. In this study, five different Swertia species viz. S. angustifolia, S. cordata, S. chirata, S. paniculata, and S. nervosa collected from Western Himalayan, India were used to screen the elite Swertia species. Optimal extraction conditions to achieve the maximum yield of swertiamarin, amarogentin, and mangiferin were found to be 5.86%, 0.710%, and 4.93% respectively which were very close to the predicted values of 5.916%, 0.711%, and 5.084% respectively by keeping microwave power (530 W), time (4 min), and solvent-to-solid (30 mL). Densitogram patterns obtained from all the test samples and standard compounds revealed that the peaks corresponding to R-f 0.57, 0.64, and 0.74 were meant for swertiamarin, mangiferin, and amarogentin respectively. HPTLC studied showed that S. paniculata and S. angustifolia contained high content of bioactive compounds and could be used as a substitute for S. chirata, whereas S. cordata and S. nervosa could not be recommended as substitutes for S. chirata. Thus, the newly developed optimized MAE and HPTLC-densitometry method for simultaneous quantification of three bioactive marker compounds in five species of Swerria can be effectively implemented for quality control of herbal formulations.
Stress, both physical and psychological, is attracting increasing attention among neuroresearchers. In the last 20 decades, there has been a surge of interest in the research of stress-induced manifestations and this approach has resulted in the development of more appropriate animal models for stress-associated pathologies and its therapeutic management. These stress models are an easy and convenient method for inducing both psychological and physical stress. To understand the behavioral changes underlying major depression, molecular and cellular studies are required. Dysregulation of the stress system may lead to disturbances in growth and development, and may this may further lead to the development of various other psychiatric disorders. This article reviews the different types of stress and their neurobiology, including the different neurotransmitters affected. There are various complications associated with stress and their management through various pharmacological and non-pharmacological techniques. The use of herbs in the treatment of stress-related problems is practiced in both Indian and Western societies, and it has a vast market in terms of anti-stress medications and treatments. Non-pharmacological techniques such as meditation and yoga are nowadays becoming very popular as a stress-relieving therapy because of their greater effectiveness and no associated side effects. Therefore, this review highlights the changes under stress and stressor and their impact on different animal models in understanding the mechanisms of stress along with their effective and safe management.

Background & objectives: Improving quality of life (QOL) of healthy people living with HIV (PLHIV) is critical needing home-based, long-term strategy. Sudarshan Kriya yoga (SKY) intervention is acknowledged for its positive impact on health. It is hypothesised that SKY would improve PLHIV’s QOL, justifying an evaluation.Methods: In this open label randomized controlled pilot trial, 61 adult PLHIV with CD4 count more than 400 cells/µl and Karnofsky scale score above 70 were enrolled. Those with cardiac disease, jaundice, tuberculosis, or on antiretroviral therapy/yoga intervention were excluded. All were given standard care, randomized to SKY intervention (31: I-SKY) and only standard of care in control (30: O-SOC) arms. The I-SKY participants were trained for six days to prepare for daily practice of SKY at home for 30 min. A validated 31-item WHOQOL-HIVBREF questionnaire was used to document effect in both arms from baseline to three visits at 4 wk interval.
Results: Baseline QOL scores, hypertension and CD4 count were similar in both arms. An overall 6 per cent improvement of QOL scores was observed in I-SKY group as compared to O-SOC group, after controlling for baseline variables like age, gender, education and occupation (p=0.016); 12 per cent for physical (p=0.004), 11 per cent psychological (p=0.023) and 9 per cent level of independence (p=0.001) domains. Improvement in I-SKY observed at post-training and in the SKY adherence group showed increase in these two domains.
Conclusions: A significant improvement in QOL scores was observed for the three health related QOL domains in SKY intervention arm. This low cost strategy improved physical and psychological state of PLHIV calling for upscaling with effective monitoring for sustainability of quality of life.

India and China face the same challenge of having too few trained psychiatric personnel to manage effectively the substantial burden of mental illness within their population. At the same time, both countries have many practitioners of traditional, complementary, and alternative medicine who are a potential resource for delivery of mental health care. In our paper, part of The Lancet and Lancet Psychiatry's Series about the China-India Mental Health Alliance, we describe and compare types of traditional, complementary, and alternative medicine in India and China. Further, we provide a systematic overview of evidence assessing the effectiveness of these alternative approaches for mental illness and discuss challenges in research. We suggest how practitioners of traditional, complementary, and alternative medicine and mental health professionals might forge collaborative relationships to provide more accessible, affordable, and acceptable mental health care in India and China. A substantial proportion of individuals with mental illness use traditional, complementary, and alternative medicine, either exclusively or with biomedicine, for reasons ranging from faith and cultural congruence to accessibility, cost, and belief that these approaches are safe. Systematic reviews of the effectiveness of traditional, complementary, and alternative medicine find several approaches to be promising for treatment of mental illness, but most clinical trials included in these systematic reviews have methodological limitations. Contemporary methods to establish efficacy and safety-typically through randomised controlled trials-need to be complemented by other means. The community of practice built on collaborative relationships between practitioners of traditional, complementary, and alternative medicine and providers of mental health care holds promise in bridging the treatment gap in mental health care in India and China.
BACKGROUND: In Traditional Tibetan medicine, Yukyung Karne has been used for the treatment of ovarian cancer. Though Yukyung Karne has been reported to be clinically effective, the molecular mechanism of its anti-metstatic action remains elusive.METHODS: The cytotoxic property of Yukyung Karne was evaluated by crystal violet staining while its ability to induce ceramide production was analyzed by sphingomyelinase assay. The anti-metastatic property was investigated using adhesion, invasion, migration and colony formation assays. The effect of Yukyung Karne on the expression of extracellular matrix components, and epithelial and mesenchymal markers were evaluated by confocal microscopy and western blotting.
RESULTS: Yukyung Karne exhibited a strong anti-metastatic property by significantly reducing the invasion, migration and colony formation ability of ovarian cancer cells. Besides it inhibited the levels of biomarkers involved in epithelial to mesenchymal transition such as down-regulation of vimentin and N-cadherin and up-regulation of epithelial E-cadherin. Yukyung Karne also induced the neutral sphingomyelinase II (nSMNaseII) enzyme activity that is known to hydrolyze sphingomyelins into pro-apoptotic intracellular molecule ceramide.
CONCLUSIONS: The study provides some compelling evidences supporting the anti-metastatic potential of Yukyung Karne which strongly suggests its possible usage as a promising alternative medicine. Thus, Yukyung Karne may be used as an anticancer and anti-metastatic agent along with other conventional anticancer therapeutics to increase their efficacy.

Cordyceps sinensis has been described as a medicine in old Chinese medical books and Tibetan medicine. It is a rare combination of a caterpillar and a fungus and found at altitudes above 4500m in Sikkim. Traditional healers and local people of North Sikkim recommend the mushroom, i.e., Yarsa gumba, Keera jhar (C. sinensis) for all diseases either as a single drug or combined with other herbs. The present study was undertaken to collect information regarding the traditional uses of cordyceps in Sikkim. It was found that most local folk healers/traditional healers use cordyceps for the treatment of 21 ailments. A modern literature search was carried out to assess whether the curative effects are valid or just blind faith of local people. Chemical constituents of cordyceps are given and pharmacological and biological studies reviewed. More mechanism-based and disease-oriented clinical studies are recommended.
AYUSH, an acronym for Ayurveda, Yoga and Naturopathy, Unani, Siddha, Sowa-Rigpa and Homeopathy represents the alternative systems of medicine recognized by the Government of India. Understanding the patterns of utilization of AYUSH care has been important for various reasons including an increased focus on its mainstreaming and integration with biomedicine-based health care system. Based on a nationally representative health survey 2014, we present an analysis to understand utilization of AYUSH care across socioeconomic and demographic groups in India. Overall, 6.9% of all patients seeking outpatient care in the reference period of last two weeks have used AYUSH services without any significant differentials across rural and urban India. Importantly, public health facilities play a key role in provisioning of AYUSH care in rural areas with higher utilization in Chhattisgarh, Kerala and West Bengal. Use of AYUSH among middle-income households is lower when compared with poorer and richer households. We also find that low-income households display a greater tendency for AYUSH self-medication. AYUSH care utilization is higher among patients with chronic diseases and also for treating skin-related and musculo-skeletal ailments. Although the overall share of AYUSH prescription drugs in total medical expenditure is only about 6% but the average expenditure for drugs on AYUSH and allopathy did not differ hugely. The discussion compares our estimates and findings with other studies and also highlights major policy issues around mainstreaming of AYUSH care.
