Rating (out of 5): 2

Safflower oil has a long history of use in traditional medicine, particularly in Chinese and Middle Eastern systems, for promoting cardiovascular health and treating what is sometimes termed "heart weakness." Traditional Chinese Medicine (TCM) often uses safflower (Carthamus tinctorius) to "invigorate blood," dissolve blood stasis, and support heart function. In these systems, "heart weakness" may refer to symptoms like fatigue, palpitations, or poor circulation, rather than the strict biomedical definition of heart failure.

Modern scientific research offers limited support for safflower oil's cardiovascular benefits. Safflower oil is high in polyunsaturated fatty acids, especially linoleic acid, which may help reduce LDL ("bad") cholesterol when used in place of saturated fats. Some clinical studies suggest that replacing saturated fats with unsaturated fats, like those in safflower oil, may reduce the risk of cardiovascular disease. However, evidence directly linking safflower oil to improved heart function or treating "heart weakness" is weak and primarily based on its ability to modestly improve lipid profiles.

Overall, the use of safflower oil for "heart weakness" is primarily justified by traditional practices rather than robust scientific validation. While it may have a place in a heart-healthy diet as a substitute for less healthy fats, it should not be considered a primary treatment for heart conditions. Consultation with a healthcare provider is recommended for any heart-related symptoms.
