The coffee plant has ancient origins. This shrub began to grow spontaneously in Ethiopia and Arabia and then developed in other countries in North Africa. From there it began to spread in Turkey where it was initially used as a digestive and stimulant. In early 1500, the first coffee-tasting shops began to open in Constantinople and then over 100 years later they came first to Vienna and then the rest of Europe. Coffee has spread so widely because as well as having stimulating properties, it also contains antioxidant substances that help eliminate free radicals. It also has diuretic qualities, dissolves fat and, in small doses, is an excellent cardiotonic.
