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.”

    • Like “Carmel Water”, still available in Spain, the name Jesuit Drops wishes to convey the idea that the drops were invented by the Jesuits many centuries ago. They weren’t, but the inventor probably thought that it would give his product historical nous.

      Carmel Water was indeed first distilled by the Carmelite monks but has long since been sold out to a pharmaceutical company.
