Citat:
Kola nuts are used mainly for their stimulant and euphoriant qualities. They have effects similar to other xanthine containing herbs like cocoa, tea, coffee, guarana and yerba mate. However, the effects are distinctively different, producing a stronger state of euphoria and well being. They have stimulant effects on the central nervous system and heart. Animal experiments indicate that kola nuts have analeptic and lipolytic (fat-burning) properties, and stimulate the secretion of gastric juices. Human studies show kola nuts have positive chronotropic and weak diuretic effects. In humans it enhances alertness and physical energy, elevates mood, increases tactile sensitivity, suppresses the appetite and is used in Africa as an aphrodisiac. Autonomic changes include increased body temperature, increased blood pressure and increased respiratory rate. Effects may last up to 6 hours after ingestion.
