Extensive research over the past quarter-century suggests that curcumin can help counter toxins and influence cell survival through other means. Due to the potent radical-scavenging activity of the curcumins, cultured human skin cells subjected to free radical attack fared better when curcumin or a mixture of the three major curcumins was administered. Furthermore, the three curcumins combined had a greater effect than an equal amount of curcumin, which has led some scientists to claim a synergistic effect from the combination.
