The use of liquid liver fractions to support the Spleen body system is justified primarily by tradition, particularly in the context of traditional Chinese medicine (TCM) and early Western organotherapy practices. In TCM, the Spleen is considered a central organ related to digestion and the transformation and transportation of nutrients. Although liver extracts are not directly tied to Spleen support in classic TCM texts, animal organ extracts—including liver—have historically been used to support organs with analogous functions. In early 20th-century Western medicine, "organotherapy" involved administering animal organ extracts (like liver) to support the health of corresponding human organs, based more on the “doctrine of signatures” than on biomedical evidence. Liver extracts are rich in nutrients such as vitamin B12, iron, and other cofactors, which are essential for hematopoiesis and overall vitality; some practitioners extrapolate these benefits to spleen support, given the spleen’s role in blood filtration and immune function.

However, there is little to no direct scientific evidence demonstrating that liquid liver fractions specifically benefit the spleen in humans, and modern clinical practice does not endorse this use. The evidence supporting liver fractions for spleen health remains weak and largely anecdotal, rooted in tradition rather than rigorous scientific validation.
