Abstract Tea is identified as the second most consumed drink in the world, and its frequent intake is related to several benefits to human health, considering its antimutagenic, anticarcinogenic, antimicrobial, anti-inflammatory, antihistamine, diuretic, calming, and above all, antioxidant effects. These effects are often associated with the action of the phenolic compounds contained in these infusions. In Brazil, among the most consumed infusions are the teas of chamomile (Matricaria chamomilla L.), lemongrass (Cymbopogon citratus (D.C.) Stapf), lemon balm (Melissa officinalis L.), anise (Pimpinella anisum L.), yerba mate (Ilex paraguariensis A. St.-Hil), peppermint (Mentha piperita L.), and green/black tea (Camellia sinensis L.). Therefore, said popularity is the reason why the mentioned species were chosen to be evaluated on inflammatory enzymes. The activity of phospholipases A2 was reduced by more than 25% after treatment with black tea and yerba mate. The most significant inhibition of protease activity was observed after incubation with black tea (40.74%), green tea (31.48%) and yerba mate (25.93%). Infusions of black and green tea reduced hemolysis in semisolid and liquid media, and for the latter, reductions of up to 50% of hemolytic activity were observed, indicating an anti-inflammatory potential of the samples. Plasma incubations with green tea, black tea and lemon balm and subsequent addition of venom (1:10 ratio; tea:PBS, v:v) prolonged the coagulation time of citrated plasma by approximately twice compared to the positive control. All controls with pure tea had a thrombolytic character, in higher proportions than the venom control, especially chamomile (273.55% dissolution). Phenolic compounds derived from phenolic acids, flavonoids, and tannins are identified as the main agents that promote the biological effects observed in this study. This is mainly due to their anti-catalytic properties exerted on inflammatory enzymes and as chelating agents of enzymatic co-factors. The evaluated teas showed potential for nutraceutical use, thus pointing to the possibility of use as an adjuvant in the treatment of diseases linked to hemostasis. world health antimutagenic anticarcinogenic antimicrobial antiinflammatory, antiinflammatory anti inflammatory, antihistamine diuretic calming all Brazil Matricaria L., L L. , L.)

Abstract The genus Eucalyptus present high content of essential oil (EO). This study evaluated the pharmacological properties of Eucalyptus grandis (EG) and Eucalyptus microcorys (EM) EOs. The major component in both EOs was 1,8-Cineole. Both essential oils prevented thrombus dissolution and reduced clotting, hemolysis, and genotoxicity induced by snake venoms. 50% (EM) and 73% (EG) were the greatest inhibitions obtained in the thrombolytic assay - thrombolysis induced by B. moojeni venom. Increases in clotting time were also observed, with values considered significant between 10-27 seconds. Lysis values 50% lower than the negative control were observed in both EOs. The EOs also protected fibrinogenolysis induced by snake venom. EM EO was more effective in reducing venom-induced DNA fragmentation in the comet assay, with arbitrary unit values 66.15% lower than the positive control. These oils present wide application potential considering the pharmacological properties observed in this study.
