The effect of aqueous extract of Stachys riederi var. japonica Miq. (Labiatae) (SRAE) on the mast cell-mediated allergic and inflammatory reactions were investigated. SRAE inhibited systemic allergic reaction induced by compound 48/80. SRAE dose-dependently inhibited passive cutaneous anaphylaxis (PCA) activated by anti-dinitrophenyl (DNP) IgE. SRAE also dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. Moreover, SRAE inhibited the secretion of tumor necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-stimulated human mast cells (HMC-1 cells). These results provide evidences that SRAE may be beneficial in the treatment of acute and chronic allergic diseases.
