Walker's Jesuits Drops
Robert Walker obtained the King's Royal Letters Patent for his remedy in 1755, and on his death, surgeon Joseph Wessels took it over. The drops were still around, under the name Wessel's Jesuit Drops as late as the 1870s. In 1843, the Medical Times published a note stating that the Drops were "a spirituous tincture of balsam of copaiba, guiacum, and oil of sassafras. They are the same as the elixir anti-venereum of Quincey."
