“…Besides, antidiarrheal properties of black tea has been demonstrated in rodents (Besra et al, 2003;Hiller and Melzig, 2010). The additional CNS stimulant properties of black tea (Einother and Martens, 2013) might be beneficial for lethargic calves. The antibacterial, antiadhesive, antidiarrheal and spasmolytic properties of black tea may be beneficial in gastrointestinal diseases.…”

A B S T R A C TEthnopharmacological relevance: In the pre-antibiotic era, a broad spectrum of medicinal plants was used to treat livestock. This knowledge was neglected in European veterinary medicine for decades but kept alive by farmers. Emergence of multidrug resistant bacterial strains requires a severely restricted use of antibiotics in veterinary medicine. We conducted a survey on the ethnoveterinary knowledge of farmers in the bilingual (French and German speaking) Western region of Switzerland, namely the cantons of Fribourg, Neuchâtel and Jura, and in the French speaking part of the canton of Bern. Aim of the study: To find out whether differences exist in plants used by farmers in French speaking and bilingual regions of Switzerland as compared to our earlier studies conducted in Switzerland. Additional focus was on plants that are used in diseases which commonly are treated with antimicrobials, on plants used in skin afflictions, and on plants used in animal species such as horses, for which the range of veterinary medicinal products is limited. Material and methods: We conducted in 2015 semistructured interviews with 62 dialog partners, mainly cattle keeping farmers but also 18 horse keeping farmers. Of these, 41 were native French (FNS) and 21 native German speakers (GNS). Detailed information about homemade herbal remedies (plant species, plant part, manufacturing process) and the corresponding use reports (target animal species, category of use, route of administration, dosage, source of knowledge, frequency of use, last time of use and farmers satisfaction) were collected. Results: A total of 345 homemade remedies were reported, of which 240 contained only one plant species (Homemade Single Species Herbal Remedy Reports; HSHR). A total of 289 use reports (UR) were mentioned for the 240 HSHR, and they comprised 77 plant species belonging to 41 botanical families. Of these, 35 plant species were solely reported from FNS, 20 from GNS, and 22 from both. Taking into account earlier ethnoveterinary studies conducted in Switzerland only 10 (FNS) and 6 (GNS) plant species connected with 7% of FNS and GNS UR respectively were "unique" to the respective language group.The majority of the UR (219) was for treatment of cattle, while 38 UR were intended to treat horses. The most UR were for treatment of gastrointestinal and skin diseases. The most frequently mentioned plants were Linum usitatissimum L., Coffea L., Matricaria chamomilla L., Camellia sinensis (L.) Kuntze, and Quercus robur L. for gastrointestinal diseases, and Calendula officinalis L., Hypericum perforatum L. and Sanicula europaea L. for skin afflictions. Conclusion: No clear differences were found between the medicinal plants used by French native speakers and German native speakers. Several of the reported plants seem to be justified to widen the spectrum of veterinary T therapeutic options in gastrointestinal and dermatological disorders in cattle and horses, and to reduce, at least to a certain degree, the need for antibiotic treatments.

“…There has been abundant research on the impact of caffeine on cognitive performance, but this evidence now includes several studies on tea consumption. In a review of the effects of tea consumption on attention and mood, Einöther and Martens (2013) reported a consistent finding that acute tea consumption improves attention, self-reported alertness and mental arousal. A recent systematic review and meta-analysis (Carnfield et al 2014) reported small to moderate effects on cognitive function and mood, which were attributable to L-theanine and caffeine.…”

“…Although caffeine is known to increase acetylcholine and dopamine transmission in the brain, implicated in attention and higher cognitive functions, less is known about L‐theanine, which is a highly bioavailable amino acid that is virtually unique to tea. Whereas caffeine is absorbed rapidly (peak plasma levels from 30 minutes after consumption; Einöther & Martens ), L‐theanine is absorbed more slowly, with reported peak plasma from 50 minutes (Van der Pijl et al . ), and so the acute effects may lag behind caffeine (Carnfield et al .…”

After water, tea is the most commonly consumed beverage worldwide, with over 80% of adults drinking tea in the UK. Lay concerns about caffeine have led to questions about the suitability of tea as a source of hydration. Several controlled trials have examined the effect of moderate caffeine consumption on fluid balance, from tea or other sources, concluding that intakes of up to 400 mg of caffeine, or six to eight servings of tea daily, are consistent with normal hydration. Unlike water, or other caffeinated beverages, tea is rich in flavonoids: plant compounds associated with health. There is now a growing body of evidence linking regular tea consumption with heart health, cognitive health, dental benefits and bodyweight management suggesting that tea may offer a healthy source of hydration. These studies are discussed in the context of typical tea intakes in the UK.

“…Global tea consumption in 2018 was estimated at 273 billion liters per annum and projected to increase to 297 billion liters by 2021 (three times as much as coffee consumption rates) . The Tea Association of the USA estimates that some 159 million Americans consume tea on a daily basis , partly because of the beverage satisfaction as well as perceived health benefits . All tea comes from the leaves or buds of the Camellia sinensis plant and, based on fermentation processing, results in the main black, white, oolong, green, yellow, and pu‐erh tea classifications.…”

the association between hot tea consumption and dual-energy x-ray-measured body fat was examined in a large representative sample of US adults (n = 5,681, 51.9% women). Results: Compared with non-tea drinkers, men who consumed 0.25 to 1 cup per day of hot tea had 1.5% (95% CI: 0.4% to 2.6%) and 1.7% (95% CI: 0.4% to 3.0%) less total and trunk body fat, respectively. The associations were stronger among men 45 to 69 years old compared with younger men (20-44 years). For men who consumed 1 or more cups per day of hot tea, lower total (−1.2%, 95% CI: −2.3% to −0.2%) and trunk body fat (−1.3%, 95% CI: −2.6 to −0.1%) was observed among men 45 to 69 years old only. In women, those who drank 1 or more cups per day had 1.5% lower (95% CI: −2.7% to −0.3%) trunk body fat compared with non-tea drinkers. Conclusions: Consumption of hot tea might be considered as part of a healthy diet in order to support parameters associated with metabolic health and may be particularly important in older male age groups in supporting reduced central adiposity.Obesity (2020) 28, 445-451.
