Liquid Extract of Capsicum 10.00 | 2 fl. ounces
Absorbent Cotton, in thin sheets 90.00 | 18 ounces
Alcohol 70.00 | 14 fl. ounces

Mix the extract with the alcohol, and pour the solution over the cotton, under pressure, so that it may become saturated evenly with the liquid. After drying, keep the medicated cotton in well-closed cartons. When freshly made, capsicum "wool" is of a pale orange colour, but it becomes bleached on keeping though without loss of strength. In order to maintain an even colour it is advisable to dye the cotton with eosin, a reddish-brown powder, which dissolves in water to form a red liquid with a green fluorescence; the fluorescence is destroyed and the liquid turned yellow by hydrochloric acid.
