Dyslipidemia is an important risk factor for atherosclerotic cardiovascular disease. Maintaining normal levels of lipid indicators can significantly reduce the risk of atherosclerotic cardiovascular disease and mortality. Empirical evidence suggests that adherence to Pueraria lobata and Pueraria thomsonii is useful for improving dyslipidemia, but evidence from randomized controlled trials is lacking. This randomized, double-blind controlled trial is therefore designed to evaluate the efficacy and safety of Pueraria lobata and Pueraria thomsonii for dyslipidemia.

Pueraria is an important Chinese herbal medicine. The Pharmacopoeia of the People's Republic of China classifies the Pueraria as Pueraria lobata and Pueraria thomsonii according to the different sources of the plant, both of them is sweet, pungent and cool in nature, and has the effects of relieving fever, quenching thirst, penetrating rashes, raising the Yang to stop diarrhea, activating the meridians and detoxifying alcohol. As early as in the Han Dynasty, Zhongjing Zhang's "Treatise on Febrile Diseases" described the famous formula "Pueraria Tang", which is still an important formula for relieving exterior syndromes.

In clinical practice, the preparations of Pueraria lobata and Pueraria thomsonii are widely used to treat headache, dizziness, hypertension, coronary heart disease, angina pectoris, myocardial infarction and other diseases. For example, the puerarin injection has the effects of dilating blood vessels, slowing down heart rate, reducing myocardial oxygen consumption and improving blood circulation in the heart and brain.

Although the puerarin has been shown to be effective in a variety of cardiovascular diseases, as of now, it is unclear whether Pueraria lobata and Pueraria thomsonii can be used as part of the daily diet to regulate blood lipids and improve dyslipidemia. Therefore, the aim of this study is to conduct a randomized, double-blind controlled trial that includes patients with mildly elevated lipids to evaluate the efficacy and safety of Pueraria lobata and Pueraria thomsonii for dyslipidemia.
