One of our visitors Berrada Ali wrote “I have been traveling from Agadir to Marrakech in Morocco yesterday (August 8, 2008), and en cours de route, I bought water melon. During a hot dog day, I don’t feel good. I measured my blood pressure with a handy apparatus -a tension meter- the result was: 7.8/15.2 for diastolic and systolic pressure. Then, I ate half a kilogram of watermelon, of a variety well known in the region of Southern Morocco – a Mediterranean variety. Almost immediately, I measured my blood pressure and the result was: 8.2/12.3 for diastolic and systolic pressures! The drop in my blood pressure could not be the effect of any agent other than the watermelon!”
