Objectives The aim of this study was to clinically evaluate a topical proprietary formulation containing lipophilic catechins (AverTeaX) on recurrent herpes labialis. Methods A double blind, placebo-controlled, randomized trial with 40 participants initially in two groups. Results Compared to the vehicle group, AverTeaX applied topically 6-8 times daily resulted in a significant reduction of clinical episode duration (median 4.5 days, range 1-11 days vs. 9 days, range 2-11 days, p=0.003) and shortened blistering/ulceration stages within an episode from a median of 3 (range 0-6) days to 1 (range 0-3) day (p=0.0003). Median quality of life scores based on a multi-question …

Tea is the second most consumed drink in the world. The beneficial effects of tea have been mostly attributed to its catechin content. Black tea is derived from the leaves of Camellia sinensis plant, and it is rich in theaflavin polyphenols, in particular theaflavin (TF1), theaflavin-3-monogallate (TF2A), theaflavin-3′-monogallate (TF2B), and theaflavin-3,3′-digallate (TF3). Vero and A549 cells were used to evaluate the effect of purified individual black tea theaflavins as anti-herpes simplex virus 1 agents. With the rise of HSV resistant strains, there is a critical need to develop novel antiherpesviral treatments. Results of the cytotoxicity assay tested by MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy-phenyl)-2-(4-sulfophenyl)-2H-tetrazolium] …
