Basic lead acetate

A white solid, it is one of several lead acetates.

[1] Goulard's extract is a solution of lead(II) acetate[2] and lead(II) oxide used as an astringent[3] during the 18th, 19th and early 20th centuries.

Lead poisoning and the development of more effective astringents caused doctors to abandon its use.

Synonymous or very closely related formulations were known as liquor plumbi subacetis dilutus,[4] eau de Goulard, extract of Saturn, vinegar of Saturn, and liquid acetate of lead.

The white water eau de Saturne differed from eau de Goulard in not containing alcohol, but was often confused with it.
