The leaves of the Piper betle Linn. (Piperaceae) are used in traditional medicine and possess anti-oxidant, anti-bacterial, anti-fungal, anti-diabetic and radioprotective activities. However, little is known about their anti-allergic activity. Therefore, the effects of P. betle ethanolic extract (PE) on the production of histamine and granulocyte macrophage-colony-stimulating factor (GM-CSF) by murine bone marrow mast cells (BMMCs) and on the secretion of eotaxin and IL-8 by the human lung epithelial cell line, BEAS-2B, were investigated in vitro. PE significantly decreased histamine and GM-CSF produced by an IgE-mediated hypersensitive reaction, and inhibited eotaxin and IL-8 secretion in a TNF-α and IL-4-induced allergic reaction. The results suggest that P. betle may offer a new therapeutic approach for the control of allergic diseases through inhibition of production of allergic mediators.
