Black tea

Definition and stakes

Addison Darre Crabtre,  The Funny Side of Physic

“ All imported tea is black, unless colored before leaving China, and is colored by prussiate of potash—a poison so deleterious as to require labelling in drug stores as “Poison.” It makes one very nervous,—good tea does not, unless used to excess,—and acts as a slow poison on the system. By its over-action on the liver, it makes one yellow, and will spoil the fairest complexion. All teas contain tannic acid, which, combining with milk, makes excellent leather of one. Black teas are sometimes colored with gypsum and Prussian blue. ”

“ Black tea is of the lowest kind, with the largest leaves. In gathering the choicer varieties, we are told on credible authority that "each leaf is plucked separately; the hands are gloved; the gatherer must abstain from gross food, and bathe several times a day." Many differences in the flavor and color of green and black teas are produced by art. Mr. Fortune says of green tea, that "it has naturally no bloom on the leaf, and a much more natural color. ”

Harper's New Monthly Magazine, No…

“ Although it now seems somewhat generally agreed that both green and black teas are made from the leaves of the same plant, yet the various writers on the subject are at considerable variance as to the mode in which the difference of appearance is brought about. Some assert that the black being the natural colored tea, the beautiful green tinge is given to the green tea by means of substances used for the purpose of dyeing it; while others hold that the green hue depends entirely on the method of roasting. ”
