Joseph Jacob Plenck (1735-1807).

Joseph Jacob Plenck (1735-1807) is considered to be the forerunner of modern European dermatology, who also compiled a list of about 800 plants with medicinal uses. Of these about 115 have diuretic properties and are currently included in various pharmacopeias. They were traditionally used to cure ascites of various causes, in urolithiasis, nephritis, cystitis, bladder ulcers, strangury, urinary retention and incontinence. Few of these plants have been fully investigated by modern medicinal chemists, and many are worthy of further study.
