The spleen is a fist-sized, spongy, dark purple organ that lies in the upper left abdomen behind the lower ribs. Weighing about 7 ounces, the spleen is the largest mass of lymphatic tissue in the body. The spleen produces white blood cells, engulfs and destroys bacteria and cellular debris, and destroys worn-out red blood cells and platelets. A series of case reports in the early 1930s demonstrated that orally administered beef (bovine) spleen extracts were able to raise white-blood-cell counts in individuals with extremely low counts, as well as to benefit patients with malaria and typhoid fever.1 2 3 However, there do not appear to be any more recent studies with these sorts of preparations. Most of the recent research with spleen extracts has focused on the use of injectable preparations or isolated spleen proteins, such as tuftsin and splenopentin.4 5 6 7 Although these preparations have been shown to enhance immune function, it is not known whether the same benefits can be obtained with oral preparations. Where are they found? Spleen extracts are available as nutritional supplements in capsules and tablets. Spleen extracts have been used in connection with the following condition (refer to the individual health concern for complete information): Rating Health Concerns Cancer chemotherapy, adverse effects Low white-blood-cell count Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit. Who is likely to be deficient? As spleen extract is not an essential nutrient, no deficiency state exists. How much is usually taken? The recommended amount depends on the concentration, method of preparation, and quality of the extract. Follow the manufacturer’s recommendation on the label. Are there any side effects or interactions? No side effects or adverse effects have been reported with the use of oral spleen preparations. Are there any drug interactions? Certain medications may interact with spleen extracts. Refer to the drug interactions safety check for a list of those medications. References: 1. Minter MM.
