The spleen is a fist-sized organ located on the lower left side of the rib cage. It’s an integral part of the lymphatic system, which fights infection, keeps body fluids in balance, and destroys old and damaged cells. It also contains white blood cells, which patrol the entire body for protection from infection.

With the advent of the isolation and synthesis of specific hormones, glandular therapy has waned in modern medicine; however, it’s still a popular therapeutic strategy employed in traditional Chinese medicine and contemporary naturopathic medicine. The roots of glandular therapy stem from the philosophy that oral ingestion of an animal gland will strengthen performance of the corresponding gland in humans. The scientific basis for animal glandulars is that they’re a rich source of hormones, hormone precursors, and organ-specific nutrients in their naturally occurring form.

Spleen extract may be employed for strengthening immune response. Low molecular–weight peptides within spleen extract have also been shown to enhance the activity of natural killer cells.
