Objectives

Narrative objectives1

Sendan alpha is a product containing extracts derived from the plant Melia azedarach, and has been shown to have potent anti-cancer activity in human tumor cells and in mouse and dog tumor models. Sendan alpha is also sold as a supplement claiming to have immune-modulating and anti-tumor effects, but scientific proof from large-scale human clinical trials is still insufficient. Therefore, we decided to conduct a human trial of Sendan alpha and examine the immunostimulatory effects of this product on immune function through blood tests.
