(also known as subacetate of lead
) is a solution of lead acetate
and lead oxide used as an astringent
during the 18th, 19th and early 20th centuries. It was named after its introducer, Thomas Goulard
. Lead's carcinogenic
properties, as well as the development of more effective astringents, led to doctors abandoning its use.
Goulard's Extract was a primary ingredient in both Goulard's Cerate and Goulard's Water.
