This effect may be entirely independent of pure stimulus, or of any disposition to mental or physical activity. Now some tea-drinkers find in the beverage exhilaration only, a lightness of mood, but they are disposed to rest and to revery, to simply a passive meditation, or an indulgence of the imagination. Others are stimulated to mental or to physical activity, and are sustained during such action. Afterwards they are refreshed when fatigued, by the same beverage. It must be evident that each person should observe the effects of tea upon himself or herself and be governed accordingly.
Tea is a poison to some temperaments, and so are strawberries.
We will sum then by conceding that all our quoted authorities are right in their conclusions, if limited to a limited class of tea-drinkers, and all are wrong, in a very broad application. Theine is the one constant agency in the effects of tea. Final firing process. This hypothesis leaves the enquiring layman in a dilemma. Tea must either enable the system to draw more heavily or more economically upon the resources afforded by recognized food, or it is itself nutriment.
