Tea and coffee do not nourish the system. The relief obtained from them is sudden, before the stomach has time to digest them. This shows that what the users of these stimulants call strength, is only received by exciting the nerves of the stomach, which convey the irritation to the brain, and this in turn is aroused to impart increased action to the heart, and short-lived energy to the entire system. All this is false strength, that we are the worse for having. They do not give a particle of natural strength. The second effect of tea drinking is headache, wakefulness, palpitation of the heart, indigestion, trembling of the nerves, with many other evils. CH 87.4
