» Lemon Tincture is prepared from lemon peel, which is the outer yellow rind of the fresh, ripe fruit of Citrus x Limon Osbeck (Fam. Rutaceae).

Prepare peel as directed for Process M in Tinctures under Pharmaceutical Dosage Forms 1151. Macerate 500 g of the lemon peel in 900 mL of alcohol in a closed container, and store in a warm place. Agitate the container frequently for 3 days or until the soluble matter is dissolved. Transfer the mixture to a filter, using talc as the filtering medium, and when most of the liquid has drained away, wash the residue on the filter with a sufficient amount of alcohol, and combine the filtrates so that the preparation is brought to a final volume of 1000 mL.
