The Influence of Piperine on the Radioprotective Effect of Curcumin in Irradiated Human Lymphocytes.

Piperine has a potent radioprotective effect at low concentration as compare to curcumin. However, an additive radioprotective effect was observed with co-treatment with piperine and curcumin at low concentration, while piperine increased the percentage of MN in normal lymphocytes when co-treated with curcumin at higher concentration.
