Wednesday, August 21, 2002Neither patients nor observers noticed any difference between those who had taken gingko and those who had taken placebo. The study was only for six weeks, but as the authors point out, the manufacturer claims benefits can be found in as early as four weeks: Our study has limitations. It is certainly possible that higher doses or longer periods of exposure than used in this study are necessary to detect changes; however, we administered the compound following the manufacturer's instructions. The manufacturer's label indicates that ginkgo should be administered at a dose of 120 mg/d and that doses of greater than 120 mg show no additional benefit. This is also the dose suggested by the German Commission E. The daily dose in the present study was 120 mg/d. The label also states that a noticeable benefit should be apparent after 4 weeks of usage. The present study evaluated cognition after a 6-week interval. Moreover, there was no indication of a statistical trend toward significance for any of the compounds on any of the measures. posted by Sydney on 8/21/2002 07:10:00 AM 0 comments 0 Comments: |
