Abstract:

The inflammatory response induced by Dieffenbachia picta, an ornamental plant, may be due to mechanical tissue damage resulting from the physical presence of calcium oxalate crystals. The toxicity arises from its ability to cause painful edema of oral mucous membranes, buccal ulcerations, and tongue hypertrophy after chewing on the stem or contact with the sap. Angioneurotic tongue edema caused by D.picta sap in live mice was standardized (DIP et al., 2004; 2011) and we compared the anti-inflammatory effect of eugenol (2-methoxy-4-(2-propenyl)phenol) to different drugs, and investigated the role of oxalate crystals in the development of the inflammation reaction. These results suggests that the compounds which inhibit antidromic vasodilation and axon reflex flare, reducing mastocyte degranulation and release of tachykinins from nerve endings would be promising agents for the treatment of angioneurotic edema.
