“…Green tea extract is a recognized rich dietary source of catechins, containing a substantial amount of catechin, (-)-epicatechin (EC), (-)-epicatechin-3-gallate (ECG), (-)-epigallocatechin (EGC) and (-)-epigallocatechin-3-gallate (EGCG) [ 30 , 31 ]. A broad range of pharmacological activities have been reported for catechins, including antiviral and nephroprotective activities, which are strongly associated with their anti-inflammatory and antioxidant properties [ 32 , 33 , 34 , 35 , 36 , 37 ].…”

Data obtained from several intensive care units around the world have provided substantial evidence of the strong association between impairment of the renal function and in-hospital deaths of critically ill COVID-19 patients, especially those with comorbidities and requiring renal replacement therapy (RRT). Acute kidney injury (AKI) is a common renal disorder of various etiologies characterized by a sudden and sustained decrease of renal function. Studies have shown that 5–46% of COVID-19 patients develop AKI during hospital stay, and the mortality of those patients may reach up to 100% depending on various factors, such as organ failures and RRT requirement. Catechins are natural products that have multiple pharmacological activities, including anti-coronavirus and reno-protective activities against kidney injury induced by nephrotoxic agents, obstructive nephropathies and AKI accompanying metabolic and cardiovascular disorders. Therefore, in this review, we discuss the anti-SARS-CoV-2 and reno-protective effects of catechins from a mechanistic perspective. We believe that catechins may serve as promising therapeutics in COVID-19-associated AKI due to their well-recognized anti-SARS-CoV-2, and antioxidant and anti-inflammatory properties that mediate their reno-protective activities.

“…The consumption of tea daily is increasing, and large amounts are consumed by adults (nearly 1 L per person per day on average) in oriental countries 11 . The positive health benefits of tea include the presence of nutrients and minerals, antioxidant activity, favorable taste, aroma, and anticancer properties 17 – 19 .…”

Excessive ingestion of fluorides might adversely affect the health of humans. Hence, this study aimed to investigate the concentrations of infusible fluoride in five different types of tea and herbal products; additionally, the probabilistic health risks associated with the ingestion of fluoride in drinking tea and herbal products were estimated. The highest and lowest concentrations of infusible fluoride were detected in black and white tea, respectively. On average, the highest amount of infusible fluoride was extracted following a short brewing time of 5 min in the case of black tea (2.54 mg/L), herbal tea (0.40 mg/L), and white tea (0.21 mg/L). The level of infusible fluoride during brewing was inversely associated with the leaf size of the tea and herbal products. Furthermore, the type of water used influenced the release of infusible fluoride; purified water yielded lower amounts of infused fluoride. The findings of the probabilistic health risk assessment indicated that the consumption of black tea can increase the fluoride intake leading to chronic exposure. Thus, the health risk posed by fluoride intake from drinking tea needs to be evaluated in more details in the future. Appropriate measures for health risk mitigation need to be implemented to minimize the total body burden of fluorides in humans.

“…Camellia sinensis use is also associated with a more favorable cardiovascular disease risk profile [ 28 ]. The positive impact of green tea on cardio-metabolic health is related to its high content of polyphenols, in particular catechins, such as epicatechin (EC), epigallocatechin (EGC), epicatechin-3-gallate (ECG), and epigallocatechin-3-gallate (EGCG) [ 29 ]. EGCG is the most prevalent catechin present in green tea, representing approximately 30–50% of the green tea catechin content, is an ester that forms from the reaction of epigallocatechin and gallic acid and acts as an antioxidant and reduces inflammation [ 30 , 31 ].…”

Introduction: Nutraceuticals are a good means to lower cardiovascular risk. Having established a reasonable pharmacological background, a new nutraceutical combination should be tested in clinical trials. Material and methods: This double-blind, placebo-controlled randomized clinical trial aims to evaluate the modulating effect, in a setting of controlled nutritional habits, of a combined food supplement with DIF1STAT (based on red yeast rice with a very low content of monacolins, linear aliphatic alcohols and niacin) and Olea europaea on plasma lipids and endothelial function, in a group of 40 healthy, moderately hypercholesterolemic patients in primary cardiovascular prevention. Results: After 8 weeks of treatment, when compared to the placebo group, the active treated patients experienced significant improvements of different metabolic parameters and endothelial reactivity compared to placebo. The treated patients showed a statistically significant percentage change in total cholesterol (-12.25 delta% vs. -1.8%, p < 0.01), low-density lipoprotein (LDL) cholesterol (-28.7 delta% vs. -1.1%, p < 0.01), high-density lipoprotein (HDL) cholesterol (+4.99% vs. +0.9%, p < 0.05), non-HDL cholesterol (-16.02 delta% vs. -1.5%, p < 0.01), SUA (-12.96 delta%, p < 0.05) and endothelial reactivity (+6.73% vs. -1.4%, p < 0.01). In both groups, there was no case of intolerance and the safety parameters were unchanged. Conclusions: The tested nutraceutical association is able to significantly improve different lipid parameters compared to placebo, and endothelial reactivity compared to baseline. Even if the study power appears to be adequate for the primary endpoints, the effect on endothelial function needs confirmation in a longer clinical trial.
