Historical Definition
Citrinula is a blistering herb called crowfoot.
Meaning
The identifying name and the reported effect both belong to the definition. Crowfoot supplies the plant vocabulary; “blistering” characterizes what the historical author attributes to it. The entry gives no species, plant part or preparation that would justify a narrower botanical determination.
The spelling must also be kept distinct from Citrinulum and Citrinulus. Those neighbouring terms are defined as a salt and a crystal, respectively. Their similar appearance is a lookup difficulty, not evidence that they name the same substance.
Places to Read
Citrinulum. A vitriol-derived salt identified through transparency and preparation.
Citrinulus. A crystal identified through a pale appearance.
