An older or archaic chemical compound name, possibly a glycerin-derived substance or glycoside variant (usage largely obsolete).
Glycer- + -izin (archaic chemical suffix). From 19th-century chemistry; most modern uses favor more specific nomenclature.
Glycerizin appears in very old chemical texts but has been replaced by more precise chemical names—it's a relic of when chemists were still figuring out molecular structures.
