A double salt of theobromin-sodium and sodium salicylate.

Properties : Theobromin sodium salicylate contains 50 per cent of theobromin and occurs as a white powder, odorless and having a saline taste. It is freely soluble in water (1:1), but is readily decomposed on exposure to carbon dioxid or by the action of acids, and must therefore be preserved in well-stoppered bottles.

Incompatibilities: Theobromin sodium salicylate is in-■ compatible with acids and has the other incompatibilities of salicylates.

Dosage.- 0.5 gm. or 7 grains, three times a day
