An Hydropic Lavament.
Take rectified Spirit of Wine 3 ounces; Spirit of Lavender 1 ounce; Pil Cochiae the greater half an ounce; Crude Opium 2 drams, mix.
It may be used alone, or (which is better) with an equal quantity of Oil of Elder Flowers by infusion, and is to be well rubbed upon the Parts, at the Fire, twice a day.
This was communicated to me as an efficacious Remedy against watery Tumours, Childrens great Bellies, and Hydropical swelled Feet. Neither is there any fear of a Gangrene from its use; for (by reason of its spirituous Particles) it cherishes native Heat, open the Pores of the Parts, and causes the viscous stagnating Lympha, either to evaporate, or be sucked into the circulating Blood.
