Dr. Diamond places great importance on the activation of the thymus gland in his practice. The thymus gland has many important functions. Among them are: (A) the production in early life of special lymphocytes called T-cells which are vitally important in immunological surveillance, which is directly concerned with resistance to infections and cancer, (B) the activation, after puberty, of the T-cells by thymus hormones, (C) involvement in the flow of lymph throughout the body, (D) the monitoring and regulation of energy flow throughout the body energy systems, initiating instantaneous corrections to overcome imbalances as they occur so as to achieve a rebalancing and harmony of body energy, and (E) the thymus serves as the link between mind and body, being the first organ to be affected by mental attitudes and stress. Hence activation and stimulation of the thymus is an essential, primary foundation of achieving and maintaining positive health.
