Escin IIb, isolated from horse chestnut, the seeds of Aesculus hippocastanum L., has positive effects on acute inflammation in animals^[1]. Escin IIb showed potent protective effects against ethanol-induced gastric mucosal lesions^[2].

Escins Ia, Ib, IIa, and IIb (50-200 mg/kg) inhibit the increase of vascular permeability induced by both acetic acid in mice and histamine in rats. Escins Ib, IIa, and IIb (50-200 mg/kg) also inhibit that induced by serotonin in rats, but escin Ia didn’t. Escins Ia, Ib, IIa, and IIb (200 mg/kg) inhibit the hind paw edema induced by carrageenin at the first phase in rats. Escin Ia (200 mg/kg) and escins Ib, IIa, and IIb (50-200 mg/kg) inhibit the scratching behavior induced by compound 48/80 in mice, but escin Ia was weakest^[1].
Escin IIb (10-50 mg/kg; p.o.) potently inhibits ethanol-induced gastric mucosal lesions^[2].
