Salvia miltiorrhiza is not only proven to be as effective as western medicine in reducing the area of ​​myocardial infarction, but also more effective in reducing “oxidative fatigue”.

Traditional herbs are often considered by some to be inconsistent with scientific medical treatment, and doubts about herbal folk treatments.

Chinese herbalists generally believe that Salvia miltiorrhiza can prevent blood stasis and myocardial infarction, but the actual medical research is not much. Dr. Zhu Yizheng, Department of Pharmacology, School of Medicine, National University of Singapore, for this reason, decided to study Salvia miltiorrhiza in a way that studies Western medicine and scientifically prove the efficacy of Salvia miltiorrhiza.

His study concluded that Salvia miltiorrhiza is as effective and less effective than ramipril in reducing the size of infarcts compared to Ramipril, an angiotensin-converting enzyme inhibitor favored by Western medicine. Oxidative stress (commonly known as "oxidative fatigue") is more effective than ramipril.

Myocardial infarction is an acute cardiovascular disease that can lead to heart rupture, arterial embolism, cardiac papillary muscle dysfunction or rupture, pericarditis, pleurisy, pneumonia, etc. Failure to save will result in death. The benefit of reducing the area of ​​myocardial infarction is to improve the survival rate after myocardial infarction and reduce the heart load.

The so-called oxidative fatigue, refers to the chemical factors and environmental factors caused by immune stress, resulting in increased body nitric oxide (or free radicals), resulting in DNA damage, promote tumor growth, cardiovascular disease or cell apoptosis. Oxidative fatigue may even lead to neurological diseases such as Parkinson's disease and Alzheimer's disease.
