Thymus extract is derived from thymus glands of animals, most commonly from young bovine calves. The thymus produces white blood cells and releases several hormones that regulate immune functions. Because the thymus gland is a major factor in the immune system, thymus extract theoretically can boost immunity, and several studies support this theory when the extract is used for specific conditions.
Immune Compromising Disorders
Some people with HIV/AIDS or other diseases that compromise the immune system use thymus extract for its possible benefits. Some studies support the use for immune system deficiencies. A study published in the May 1987 issue of “Annals of Allergy” indicated effectiveness of the extract Thymostimulin for successfully resolving combined immunodeficiency in an infant, without need for continued therapy. Another thymus extract, Thymomodulin, showed benefits for enhancing the immune system in people over 74 years of age with reduced immune function. During this study, published in the October 1994 issue of the “Journal of Chemotherapy,” treatment with Thymomodulin for six weeks had a restoring effect on the immune system.
