“…[17] Similarly to YM, consumption of black tea and green tea (Camellia sinensis), which are also rich in polyphenols and xhantines, result in a protective effect on bone, lowering fracture risk. [18][19][20] The presence of polyphenols with an-tioxidant effect could explain this favorable effect on bone tissue, [21] considering that reactive oxygen species induce the apoptosis of osteoblasts and osteocytes and increase osteoclastogenesis leading to bone loss. [22] A relationship between bone loss with age and oxidative stress was found by the assessment of advanced protein oxidation products such as malondialdehyde (MDA) and superoxide dismutase (SOD) in femur samples of young, adult, and elderly rats.…”

Background: Yerba mate (YM, <i>Ilex paraguariensis</i>) consumption beneficially affects the bones. However, whether YM components exert their effect on bone cells directly remains elusive.Methods: We evaluated how main YM components affect osteoblastic (MC3T3-E1) and osteocytic (MLO-Y4) cells <i>in vitro</i> when administered separately or in an aqueous extract. MC3T3-E1 and MLO-Y4 cells were exposed to three different experimental conditions: (1) Caffeine, chlorogenic acid, and their combinations; (2) Caffeine, rutin, and their combinations; (3) Aqueous YM extract.Results: All polyphenol and caffeine concentrations as well as that of their tested combinations significantly increased MC3T3-E1 cell viability from 16.6% to 34.8% compared to the control. In MLO-Y4 cells, the lowest rutin and the two highest caffeine concentrations significantly increased cell viability by 11.9, 14.9, and 13.7%, respectively. While rutin and caffeine combinations tended to increase MLO-Y4 cell viability, different chlorogenic acid and caffeine combinations did not affect it. Finally, the aqueous YM extract significantly increased MLO-Y4, MC3T3-E1, and differentiated MC3T3-E1 cell viability compared to the control without treatment.Conclusions: YM components (rutin, chlorogenic acid, and caffeine) positively affected bone cells, mainly pre-osteoblast cells. Moreover, the aqueous YM extract significantly increased MLO-Y4, MC3T3-E1, and differentiated MC3T3-E1 cell viabilities indicating an additional relevant nutritional property of YM infusion. Further studies would be required to elucidate the underlying effector mechanism of YM on the bones and its relationship with previously described in vivo positive effects.

“…Tea is widely consumed worldwide and it is well known that in addition to alkaloids, amino acids, polyphenols, carbohydrates, and aromatics, herbal tea also possesses vitamins and minerals. Consumption of herbal tea might prove beneficial in preventing certain medical conditions, such as heart disease, Parkinson's disease, and various malignancies [ 3 ]. Calendula is a sanctification and detoxifying herb and the infusion is used in the treatment of long-standing infections [ 4 ].…”

Aim To assess the anti-inflammatory and antioxidant properties of Calendula officinalis tea formulation. Materials and methods In this study, a formulation of 2 grams of dried marigold flower petals and 100 milliliters (ml) of distilled water was subjected to anti-inflammatory testing using albumin denaturation assay and anti-protease activity and antioxidant testing by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay. An independent sample t-test was done to compare the anti-inflammatory and antioxidant potentials of marigold tea formulation and control using SPSS version 22.0 software (IBM Corp., Armonk, NY), and any p-value less than 0.05 was considered statistically significant. Results The highest anti-inflammatory and antioxidant activities of marigold extract were exhibited at 10 microliters (µl) and 20 µl (p-value = 0.002 and 0.000), respectively. The anti-inflammatory activity was higher than the control at all concentrations, whereas the antioxidant activity was higher at lower concentrations when compared to higher concentrations. Conclusion Marigold flower tea formulation exhibited better anti-inflammatory and antioxidant activities than the controls and therefore could be evaluated as a potential therapeutic agent.
