With brain-workers it has always been a favorite beverage, the subdued irascibility, the refreshed spirits, and the renewed energies which the student so often owes to it, have been the theme of many an accomplished pen. Yet it is impossible to speak too strongly against the not uncommon habit frequently adopted by ardent students when prosecuting their studies far into the night, to resist the claims of nature for repose, and keep off the natural sleepiness by repeated libations of tea. That it answers the purpose for the time being cannot be denied, but the object is often attained at a fearful price, the persistent adoption of such a practice being certain to lead to the utter destruction of the health and vigor of both body and mind. Less injury in such cases will result from the use of coffee, there being this difference between the morbid states of the nervous system produced by coffee and that resulting from tea. The effect of the former generally subsides or disappears entirely on relinquishing its use, while that caused by tea is more permanent and often incapable of being ever eradicated. That tea does not suit all temperaments, constitutions and all ages is no valid argument against its general use. That it is less adapted to children than adults is admitted; indeed, for very young children it is entirely improper, producing in them, like all narcotics, a morbid state of the brain and nervous system in general. It is also unsuited to those of an irritable temperament as well as for those of a leuco-phlegmatic constitution, such persons illy bearing much liquid of any kind, particularly in the evening, prospering best on a dry diet at all times, and to which young children especially should be strictly confined. Briefly it may be summed up that tea is best suited to persons in health, the plethoric and sanguine, and upon which principle it is the proper diet at the beginning of fevers and all inflammatory complaints. Besides the more obvious effects with which all who use it are familiar, tea saves food by lessening the waste of the body, thus nourishing the muscular system while it excites the nervous to increased activity, for which reason old and infirm persons derive more benefit and personal comfort from its use than from any corresponding beverage. To the question “does tea produce nervousness?” the answer is “in moderation, emphatically No!” One to two cups of tea prepared moderately strong, even when taken two to three times per day will not make any one nervous, but when drunk to excess it undoubtedly will. Tea-testers and experts who are tasting it all the time, day in and day out, for the purpose of valuing it, are frequently made nervous by it, soon recover by a little abstinence. Tea, like liquor and drugs, when taken in moderate quantities, produce one effect, but when used in large and immoderate quantities produce just the contrary result. China and Japan
