Indication: Prostate cancer
Source: Cancer, 2003;97(6):1442-6.
Research: Patients were instructed to take 6 grams of green tea per day orally in six divided doses. Each dose contained 100 calories and 46 mg of caffeine. Patients were monitored monthly for response and toxicity. The patients could drink the green tea as they wished, either hot, iced, with juice or with additional sweetener. All subjects in the study had advanced androgen-independent prostate cancer.
Results: At the start of the study, all patients reported drinking the specific amounts of green tea daily. After about one month, researchers found patients were dropping out of the study because their prostate cancer was not regressing and because of side effects attributed to the high-dose green tea. Of the 42 patients, only one showed a short term drop in his prostate-specific antigen (PSA) levels. None of the patients experienced a sustained decline in PSA levels. In addition, 69% of patients reported mild side effects of diarrhea, nausea, vomiting and abdominal pain. Seventeen percent of the patients had moderate to severe side effects, including insomnia, diarrhea and confusion.
