Spleen extract
Spleen extract


The spleen is an organ in people and animals. Its main jobs are to break down and remove old and damaged red blood cells and to provide some white blood cells to fight infection. Spleen extract is produced from animal spleens and is used as medicine.

People use spleen extract for conditions such low white blood cell counts, cancer, autoimmune diseases, infections, and many others, but there is no good scientific evidence to support these uses.
When taken by mouth: It is not known if spleen extract is safe or what the side effects might be. There is some concern about contamination of spleen extract from sick or diseased animals. In particular, there is concern that spleen extract might cause bovine spongiform encephalitis (BSE) due to contamination if obtained in countries where BSE has been reported. While this side effect hasn't been reported in humans, it's best to avoid using spleen extract from countries where BSE has been reported.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if spleen extract is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.
