Caution:

Cola nut can cause sleeplessness, anxiety, tremor, palpitations, over-excitability, nervous restlessness, and gastric irritation. The caffeine constituent can cause a fast heartbeat, quickened respiration, tremors, delirium, vomiting, convulsions, diuresis, agitation, ringing in the ears, premature heartbeat, and arrhythmias. High doses of cola nut providing 250 mg of caffeine can also increase blood pressure. This doesn't seem to occur in people who habitually consume caffeine products
