It contains Proline-Rich-Polypeptides (PRPs) which help to modulate normal immune responses. PRPs are tiny information-carrying proteins with amazing adaptability. In times of intense physical stress, enhance immune system activity by promoting the production of cytokines. In the opposite situation, when a healthy immune system reacts to environmental factors through cytokine production, PRPs send signals via specific cell receptor sites to decrease the production of cytokines in order to balance the immune system. PRPs help regulate the thymus gland (the body's central command for the immune system), stimulating an underactive immune system or down-regulating an overactive immune system.
