RESUMEN
The Effects of Cinnamomum camphora and Zingiber officinal beverages and their combination has been studied on different clinical parameters in thirteen adult healthy Yemeni volunteers age 23-25 years. Three trials have been conducted, in which the volunteers received ginger, camphor and the combination of ginger and camphor. Before the trials and after each trial the following parameters were measured: the systolic and diastolic blood pressures, the pulse rate, serum cholesterol, and the fasting blood sugar. Moreover the sperm count was also measured. The two beverages showed opposite actions on the blood pressure, the pulse rate, and on the sperm count. Where ginger increased these parameters while camphor decreased them. Either ginger or camphor lowers fasting blood pressure, serum cholesterol, and the combination of both lowers these parameters further
