A placebo-controlled double-blind study found that Crataegus-Special extract WS 1442 had beneficial effects in the treatment of patients with cardiac insufficiency (NYHA II), a condition in which the heart can’t pump enough blood throughout the body. For 8 weeks patients (n=136) were treated with either Crateugus-Special extrakt (CS) or placebo. Results show a significant improvement in heart function in the CS group while participants in the placebo group became worse. CS patients also reported reduced shortness of breath, ankle swelling, and an overall better quality of life (especially mental well-being) compared to placebo and the treatment was well tolerated.
