Two parts of the safflower are primarily used: the flower itself and safflower seeds. There are two types of safflower oil with corresponding types of safflower varieties: those high in monounsaturated fatty acid (oleic) and those high in polyunsaturated fatty acid (linoleic). Currently, the seed varieties that produce oil high in oleic acid and very low in saturated fatty acids predominate in the United States market. High oleic safflower oil is lower in saturates and higher in monounsaturates than olive oil. In the U.S. diet, safflower oil has been frequently substituted for oils with higher saturated fat content, as monounsaturated fat may have a beneficial effect on the risk of coronary heart disease. Some clinical studies have shown that safflower oil supplementation may be helpful in patients with cystic fibrosis, Friedreich's ataxia, and neurotoxicity from lithium. However, more study is needed in these areas before a firm conclusion can be drawn. In traditional Chinese medicine, safflower is used to invigorate the blood, dissipate stasis, amenorrhea (absence of menstruation), pain, and traumatic injuries. It is also used to "calm" a live fetus and abort a dead fetus, and is therefore used cautiously during pregnancy.
Liver extract and desiccated (dried) liver have been marketed as iron supplements for over a century. The extract is processed cow or pig liver that may either be a freeze-dried brownish powder or a concentrated liquid that has had most of the fat and cholesterol removed. Preliminary clinical studies indicate that liver extract may be helpful in treating hepatic (liver) dysfunction. In addition, liver extract seems to work synergistically with interferon in treating hepatitis C and other viral infections. More research is needed in these areas. Laboratory studies indicate that liver extract may have some effects that could be useful in treating certain forms of cancer, such as the ability to direct migration of metastasizing cells and the inhibition of DNA, RNA, and protein formation. More research is needed in these areas to quantify liver extract's properties. Some concern has been raised about the safety of liver extract, as it is made of animal liver, which may be infected with parasites, bacteria, or prion diseases. Although there are currently no available reports of diseases such as bovine spongiform encephalitis (BSE, or "mad cow disease") being transmitted by liver extract, the U. S. Food and Drug Administration (FDA) still cautions against the use of any animal organ extract. It is not clear how the processing of liver extract affects the transmission of these organisms.
