Increasingly, interest in and the uptake of herbal infusions has advanced, namely, owing to their bioactive properties and potential links to health. Given this, the purpose of the present review was to collate evidence from human trials for five popular herbal infusions.

The systematic review comprised ten human trials (560 participants), investigating inter-relationships between herbal infusions consumption and health. Only human studies involving German chamomile (Matricaria chamomilla L. Asteraceae), ginger (Zingiber officinale Roscoe Zingiberaceae), lemon balm (Melissa officinalis L. Lamiaceae), peppermint (Mentha x spicata L. Lamiaceae)/spearmint (Mentha spicata L. Lamiaceae) and rosehip (Rosa canina L. Rosaceae) teas were included in the present paper.

Most herbal infusions serve as a good source of flavonoids and other polyphenols in the human diet. Studies included in this paper indicate that herbal infusions (1-3 cups tended to be drank daily; infusion rates up to 15 min) could benefit certain aspects of health. In particular, this includes aspects of sleep quality and glycaemic control (German chamomile), osteoarthritic stiffness and hormone control (spearmint), oxidative stress (lemon balm) and primary dysmenorrhea (rosehip).

Ongoing research is needed using homogenous herbal infusion forms, brewing rates and volumes of water to further reinforce these findings. In the meantime, herbal infusions could provide a useful supplementary approach to improving certain aspects of well-being.

The present paper collates evidence from human trials for five popular herbal infusions.

White tea is an unfermented tea made from young shoots of Camellia sinensis protected from sunlight to avoid polyphenol degradation. White tea contains a high level of polyphenolic compounds known as catechins. Several types of evidence have suggested that tea consumption has benefits in body weight and endurance maintenance. This study was designed to evaluate the effect of white tea on body weight and endurance of animal models.

This research was an intervention design using 20 Wistar white rats (Rattus Norvegicus) in body weight between 150 and 200 g. The rats were randomized into four groups, three groups receiving white tea drink (WTD) with different doses and the other group receiving plain water in equal volume as a control group for four weeks. The forced swim test (FST) was done to measure their struggling capacity, and digital bodyweight to measure the weight.

Intervention (WTD Groups and Control) caused weight gain among except G3 with the highest doses of white tea. The result showed that WTD intake in G3 had a significant difference (p < 0.05) on body weight gain compared to control. The authors found that WTD in a specific dose (G3: 0.22 mg) tends to maintain the body weight of animals (219.2 ± 41.96; 212.6 ± 46.90, respectively), while other doses caused weight gain. WTD also significantly increased the swimming and struggling capacity of rats that represented improvements the endurance along with the test. There was a statistically significant difference in endurance among all groups (p < 0.05).

The results of this study can be followed as human intervention research as an input for nutritionists and sports scientists to explore the beneficial effect of white tea.

The study examined the utilisation patterns of healthcare services among tea garden workers and analysed the factors influencing utilisation in an Indian context.

The authors employed a mixed-method approach and an explanatory sequential design for the study. A survey was conducted in the beginning followed by in-depth interviews in a north-eastern state of India (Assam). Andersen health behaviour model was used to explore the factors influencing healthcare utilisation. The sample size for the survey and in-depth interviews were 300 and 19, respectively, recruited employing multistage random and purposive sampling techniques.

Out of 300 workers surveyed, 169 (56.3%) were females, 257 (85.7%) were married, 77 (25.7%) were illiterates and 229 (76.3%) had monthly household income less than 100 US$. The survey also found that 47.3% and 15.3% had non-communicable and communicable disease respectively. Most of the workers (67.3%) utilised government facilities, and close to one third (28.7%) utilised tea garden hospitals. About 63.3% had health insurance, but a majority (78.9%) did not use it previously. The analyses of interviews explored the need, enabling, predisposing factors under three important themes influencing utilisation of healthcare services among the workers.

The study generates evidence to strengthen the Indian Plantation Labour Act, 1951 for tea garden worker's welfare protection and warrants transition from colonial-era policies to contemporary industry realities in order to improve their living, employment, nutritional and health conditions.

The research adds to the existing literature on overall healthcare services utilisation (including coverage and utilisation of health insurance) among blue collar workers who usually lack access to healthcare facilities and explores important factors that determine utilisation in the Indian context.

The purpose of this paper is to investigate the health and medicinal importance of bush tea (Athrixia phylicoides DC) and special tea (Monsonia burkeana Planch. ex Harv), two of Southern African indigenous herbal teas.

The two herbal teas, A. phylicoides and M. burkeana were extracted individually and in combined ratios for analysis. The phenolic content was determined and the different phenolic compounds were identified using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC). The anti-diabetic activity of the teas was determined by evaluating the inhibition of both α-amylase and α-glucosidase in vitro. The anti-proliferative activity was measured on human cervical cancer (HeLa) cell line using the MTT (3-(4,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium) assay.

Gallic acid, chlorogenic acid and quercetin were identified to be present in significant quantities by TLC. The HPLC quantified the presence of catechin (1.567 mg/g) and chlorogenic acid (1.862 mg/g) in special tea while chlorogenic acid (1.288 mg/g) was present in bush tea. Bush tea and special tea expressed significant levels of phenolic content and high antioxidant activities. Special tea (S100) expressed high inhibition of α-amylase, α-glucosidase and HeLa cell line proliferation when compared to bush tea (B100).

Both bush tea and special tea could provide an alternative for treatment and management of both diabetes and cervical cancer. However, future studies are needed to investigate their synergistic effect with a wide range of other commercial herbal teas.

This research is designed to optimize the business process of a green tea dealer, who is a key supply chain partner of the Sri Lankan tea industry. The most appropriate trips for each vehicle in multiple trip routing systems are identified to minimize the total cost by considering the traveling distance.

The study has followed the concepts in vehicle routing problems and mixed-integer programming mathematical techniques. The model was coded with the Python programming language and was solved with the CPLEX Optimization solver version 12.10. In total, 20 data instances were used from the subjected green tea dealer for the validation of the model.

The result of the numerical experiment showed the ability to access supply over the full capacity of the available fleet. The model achieved optimal traveling distance for all the instances, with the capability of saving 17% of daily transpiration cost as an average.

This study contributes to the three index mixed-integer programing model formulation through in-depth analysis and combination of several extensions of vehicle routing problem.

This study contributes to the three index mixed-integer programming model formulation through in-depth analysis and combination of several extensions of the vehicle routing problem.

The proposed model provides a cost-effective optimal routing plan to the green tea dealer, which satisfies all the practical situations by following the multiple trip vehicle routing problems. Licensee green tea dealer is able to have an optimal fleet size, which is always less than the original fleet size. Elimination of a vehicle from the fleet has the capability of reducing the workforce. Hence, this provides managerial implication for the optimal fleet sizing and route designing.

Developing an optimization model for a tea dealer in Sri Lankan context is important, as this a complex real world case which has a significant importance in export economy of the country and which has not been analyzed or optimized through any previous research effort.

This study aims to estimate the impact of refugee inflows on host countries’ entrepreneurial rates. The refugee crisis led to an increased scientific and public policy interest in the impact of refugee inflows on host countries. One important perspective of such an impact, which is still underexplored, is the impact of refugee inflows on host countries entrepreneurial rates. Given the high number of refugees that flow to some countries, it would be valuable to assess the extent to which such countries are likely to reap the benefits from increasing refugee inflows in terms of (native and non-native) entrepreneurial talent enhancement.

Resorting to dynamic (two-step system generalized method of moments) panel data estimations, based on 186 countries over the period between 2000 and 2019, this study estimates the impact of refugee inflows on host countries’ entrepreneurial rates, measured by the total early-stage entrepreneurial activity (TEA) rate and the self-employment rate.

In general, higher refugee inflows are associated with lower host countries’ TEA rates. However, refugee inflows significantly foster self-employment rates of “medium-high” and “high” income host countries and host countries located in Africa. These results suggest that refugee inflows tend to enhance “necessity” related new ventures and/ or new ventures (from native and non-native population) operating in low value-added, low profit sectors.

This study constitutes a novel empirical contribution by providing a macroeconomic, quantitative assessment of the impact of refugee from distinct nationalities on a diverse set of host countries' entrepreneurship rates in the past two decades resorting to dynamic panel data models, which enable to address the heterogeneity of the countries and deal with the endogeneity of the variables of the model.

The aim of this study was to determine the prevalence of complementary and alternative medical applications (CAM) and non-drug treatments of women during their pregnancies, postpartum periods and the changes between these periods. The Screening Form for Non-pharmacologic Methods Used during Pregnancy and Postpartum period was administered to the participants. Passiflora (Incarnata), Hypericum perforatum (St. John's Wort), omega 3 supplements, bright light treatment, transmagnetic stimulation, S-adenosyl-methionine, herbal teas, biofeedback/neurofeedback, amulets, exercise, acupuncture and psychotherapy were investigated. The ratio of the use of one of the CAM methods for psychiatric complaints during people's lifetime was found to be 33.3% (n=162). Herbal teas were the main practice used during pregnancy (58.8%) and the postpartum. The use of CAM according to the utilization periods of the participants statistically significantly decreased in those who were currently pregnant (Cochran's Q=298.007; P<0.05). The use of participants' non-drug treatments in the periodical follow-up decreased in those who are currently pregnant and increased during the postpartum period.

Thailand has seen waves of youth-led protests over the past three years. Pro-democracy youth activists have vociferously criticised authority figures: teachers, parents and political leaders, especially the king. Drawing on vignettes assembled over a 14-year ethnographic work with young people in Thailand, as well as on current research on youth (online and offline) activism in Bangkok, I examine the multi-layered meaning of kinship in Thai society. The chapter reveals the political nature of childhood and parenthood as entangled modes of governance that come into being with other, both local and international cultural entities. I argue that Thai youth activists are attempting to rework dominant tropes that sustain “age-patriarchy” in the Buddhist kingdom. Their “engaged siblinghood” aims to reframe Thailand's generational order, refuting the moral principles that establish citizens' political subordination to monarchical paternalism and, relatedly, children's unquestionable respect to parents. As I show, Thai youth activists are doing so by engaging creatively with transnational discourses such as “democracy” and “children's rights,” while simultaneously drawing on K-pop icons, Japanese manga and Buddhist astrology. In articulating their dissent, these youths are thus bearers of a “bottom-up cosmopolitanism” that channels culturally hybrid, and politically subversive notions of childhood and citizenship in Southeast Asia's cyberspace and beyond. Whatever the outcome of their commitment, Thai youth activism signals the cultural disarticulation of the mytheme of the Father in Thailand, as well as the growing political influence of younger generations in the region.
