Tincture of lemon peel was a new official preparation of the U. S. P. VIII. Spirit of lemon made from oil of lemon was abandoned, because the poor quality of the oil with which it was likely to be made caused it to have a terebinthinate flavor. The 50 per cent. tincture made by macerating fresh lemon peel in alcohol was proposed by Scoville and the present formula produces a very satisfactory preparation.
This tincture was doubled in strength at the 1898 revision of the Br. Pharm., but is now only about one-half the strength of the U. S.. tincture. It is made with strong alcohol instead of proof spirit formerly used. It forms a grateful aromatic addition to tonic infusions, etc.
Dose, from one to two fluidrachms (3.75-7.5 mils).
