[The effect of a homeopathic drug on the blood pressure of hypertensive patients--a randomised double-blind controlled parallel group comparative trial].

Pumpan in a dosage of 3 x 10 drops daily over 6 weeks does not differ in its effect on systolic and diastolic blood pressure significantly from placebo. The tolerance was excellent: not one single patient had to be withdrawn from the study due to side effects. Blood lipids (cholesterol, HDL-, LDL-cholesterol and triglyzerides) did not change, neither in the placebo nor in the verum group.
