The chemopreventive potential of cardamom was evaluated on 7,12-dimethylbenz[a]anthracene-initiated and croton oil-promoted mouse skin papillomagenesis. A significant reduction in the values of tumor incidence, tumor burden, and tumor yield and the cumulative number of papillomas was observed in mice treated orally with 0.5 mg of cardamom powder in suspension continuously at pre-, peri-, and post-initiational stages of papillomagenesis compared with the control group. The average weight and diameter of tumors recorded were also comparatively lower in the cardamom-treated mouse group. Treatment of cardamom suspension by oral gavage for 15 days resulted in a significant decrease in the lipid peroxidation level of the liver (P < .01). In addition, the reduced glutathione level was significantly elevated in comparison with the control group (P < .05) following cardamom suspension treatment. Taken together, these findings indicate the potential of cardamom as a chemopreventive agent against two-stage skin cancer.
