Source of validity: Traditional
Rating (out of 5): 2

Beef liver has historically been used in various traditional medicine systems to support heart health or treat symptoms described as "heart weakness." This practice is largely rooted in the "Doctrine of Signatures," a belief common in ancient and medieval medicine that consuming an organ from an animal could benefit the corresponding organ in humans. Beef liver, being rich in nutrients such as iron, vitamin B12, folate, and CoQ10, was thought to strengthen the blood and, by extension, support cardiovascular function and general vitality. However, while beef liver is an excellent source of nutrients that are important for overall health—including those relevant to heart function—there is limited direct scientific evidence specifically validating its use for treating heart weakness or heart disease. Modern nutritional science recognizes beef liver as a nutrient-dense food beneficial for preventing deficiencies (like anemia), but clinical trials or systematic reviews supporting its use as a targeted therapy for heart weakness are lacking. Thus, its reputation in this context is based more on traditional practices and general nutritional content than on robust scientific validation.
