Album graecum

Album græcum, or stercus canis officinale, is the dung of dogs or hyenas that has become white through exposure to air. It is used in dressing leather.

White dog dung was formerly used as a medicinal drug, often mixed with honey, to cleanse and deterge, chiefly in inflammations of the throat. Externally, it was used as a plaster, spread on skin to close and heal wounds.
