A botanical ointment containing a green tea extract called sinecatechins is an effective treatment for external genital and anal warts, according to the results of a controlled study.
Genital and anal warts are caused by human papillomavirus (HPV), and there has been a lack of effective, well tolerated treatments.
Researchers assigned over 500 adults with 30 warts to either sinecatechins ointment or a placebo. In the sinecatechins groups, warts cleared completely in roughly 57 percent of patients, compared to just 34 percent of subjects in the control group.
