This late 18th century document describes herbal prescriptions to relieve complaints of "Gravel" and "Stone." One of the remedies called for horsemint, a popular antiseptic herb, and red onions.

The term "gravel" was used to describe a calcium build up in the urinary tract, also known as urinary tract stones, where sand-like deposits caused blockage. The term "stone" refered to kidney stones. The weed called for in the gravel recipe is likely smartweed, a common ingredient in traditional homeopathic remedies, used to combat infections.
