ZGCD improves diabetic cardiomyopathy
We examined how Zhigancao Decoction (ZGCD) affects diabetic cardiomyopathy (DCM), aiming to uncover its clinical benefits and underlying mechanisms. After analyzing numerous studies, we found that ZGCD significantly improves cardiac function and reduces blood pressure more effectively than conventional treatments. Additionally, it appears to have fewer side effects. The positive effects are likely linked to its ability to influence the AGEs-RAGE signaling pathway, boost lipid metabolism, and reduce atherosclerosis. However, it's important to note that more research is needed to fully understand these mechanisms.

KSP shows potential heart health benefits
We investigated how Kgengwe seed powder (KSP) impacts cardiovascular health by examining its effects on low-density lipoprotein receptor knockout (LDL-r-KO) mice. Over 20 weeks, we fed one group of mice an atherogenic diet with 10% KSP, while the control group received no supplement.

The treatment led to higher levels of beneficial metabolites like amino acids and various fatty acids in the blood of the KSP group. Notably, there was a significant decrease in atherosclerotic lesions in those mice, implying a potential protective effect of KSP against heart disease. However, for a fuller understanding, more research is necessary to detail the mechanisms behind these findings.

Strong antiviral effect
542 people found this helpful
Excellent antiviral and immunomodulating agent. L-Lysine boasts a more than 95% effectiveness in treating viral diseases compared to 50-80% for antiviral drugs, regardless of the disease stage. Even in cases where it’s less effective, it prevents disease progression and enhances overall well-being. Additionally, it improves brain function and increases stress resilience.
