To evaluate the use of Chinese herbal medicine as a complementary therapy for the reducing chemotherapy-induced toxicity
Patients were randomly assigned to one of three Chinese herbalists who evaluated and prescribed combination, single-item, packaged, herbal extract granules. Herbalists completed university training and were licensed to practice Chinese herbal medicine (CHM) in Hong Kong and China. Patients were randomly assigned to each group and received either CHM or placebo packages with corresponding serial numbers in a 14-day supply at each clinic visit. The placebo package contained nontherapeutic herbs with an artificial smell and taste similar to typical herb tea. Each patient completed the log for each day’s consumption. On days 1 and 14, patients met with the herbalist in the clinic setting for evaluation and the herbalist documented the visit in case report form. A quality-of-life questionnaire was completed at baseline, day 1 of each cycle, and after four months.
The sample consisted of 120 patients with early-stage breast and colon cancer receiving adjuvant treatment in a university-based cancer center in Hong Kong.
