Antiphlogistic effect by zeolite as determined by a murine inflammation model

Zeolite (65% clinoptilolite, 30% mordenite, and 5% smectite) shows antiphlogistic properties shortly after exposure. Representative histological sections from mice ears exposed to TPA (4 h) and stained with hematoxylin-eosin treated with 1 mg ear-1 zeolite for 24 h (20× Scale = 100 μm). Arrows indicate the infiltrated leukocytes.
