OBJECTIVE: Given the possibility of adverse side-effects, interactions with medicines and poisoning by contaminants among herbal medicine consumers (HM), we aimed to describe the consumption of HM by health centre users being treated with medicines. DESIGN: Cross-sectional, observational study.Setting. Thirteen health centres in the Community of Valencia. PATIENTS AND OTHER PARTICIPANTS: Users of either sex, over 14, chosen for a study of use of medicines to find differences between the sexes. MEASUREMENTS AND MAIN RESULTS: The study variables, age, gender, education, consumption of medicines and use of HM, were gathered from the clinical records, the long-treatment card and an ad hoc structured survey. 801 out of 812 users took medicines. 159 took HM (19.6%; 95% CI, 16.9-22.3); average age 55.8 (SD, 16.5); women 58.5% (95% CI, 50.8-66.1). They took 226 HM (mean of 1.42; 95% CI, 1.32-1.52). Men consumed more HM (p < 0.05). There were no differences in consumption of HM for age, educational background or number of medicines taken. 42.8% (95% CI, 35.1-50.2) of those who took HM attended for consultation over 10 times in the previous year. 96.9% (95% CI, 93.7-98.4) of HM were taken by self-medication. They were consumed: <<because I like them>> by 36.7% (95% CI, 30.4-43.0); stomach problems, 19.5% (95% CI, 14.3-24.6); nerves/depression, 12.8% (95% CI, 8.5-17.2); intestinal disorders, 10.6% (95% CI, 6.6-14.6); insomnia 5.8% (95% CI, 3.1-9.6). 49.1% (95% CI, 42.6-52.6) were manufactured HM. CONCLUSIONS: One of every five patients being treated with medicines is also taking HM by self-medication. The health authorities and doctors should advise of the risks to health and of the counter-indications of these products.
