In addition to its role in platelet aggregation, the Salvia miltiorrhiza root extract also has a significant impact on blood vessel protection. The endothelium, which lines the inner surface of blood vessels, is crucial for maintaining vascular homeostasis.

The extract can improve endothelial function by promoting the production of nitric oxide (NO). NO is a key molecule in regulating blood vessel dilation and preventing the adhesion of platelets and white blood cells to the vessel wall. Moreover, it can also reduce inflammation in blood vessels, which is another important factor in protecting the integrity of blood vessels.

5. Neuroprotective Effects

The Salvia miltiorrhiza root extract has neuroprotective effects, which is highly relevant in the context of neurodegenerative diseases. Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease are characterized by the progressive loss of neurons in the brain.

Research has suggested that the extract may protect neurons from damage through multiple mechanisms. It can reduce oxidative stress in the brain, which is often associated with neurodegeneration. Additionally, it may also modulate certain signaling pathways involved in neuronal survival and function. For example, it has been shown to affect the phosphatidylinositol 3 - kinase (PI3K)/Akt signaling pathway, which is important for neuronal protection.

6. Anti - inflammatory Properties

Chronic inflammation is associated with a wide range of diseases, including autoimmune diseases, cardiovascular diseases, and cancer. The Salvia miltiorrhiza root extract exhibits anti - inflammatory properties.

It can inhibit the production of inflammatory cytokines such as interleukin - 1β (IL - 1β), interleukin - 6 (IL - 6), and tumor necrosis factor - α (TNF - α). These cytokines play important roles in initiating and perpetuating the inflammatory response. By reducing the levels of these cytokines, the extract can help to alleviate inflammation in the body.

7. Hypolipidemic Effects

Abnormal lipid metabolism is a common problem, especially in modern society with high - fat diets. The Salvia miltiorrhiza root extract has hypolipidemic effects.

It can lower blood lipid levels, including reducing triglycerides, total cholesterol, and low - density lipoprotein cholesterol (LDL - C). At the same time, it may increase high - density lipoprotein cholesterol (HDL - C), which is often referred to as "good cholesterol" as it helps to remove cholesterol from the bloodstream. The mechanisms underlying these hypolipidemic effects may involve the regulation of lipid - metabolizing enzymes and the uptake and transport of lipids in the body.

8. Antihypertensive Activity

High blood pressure is a major risk factor for cardiovascular diseases. The Salvia miltiorrhiza root extract has been found to possess antihypertensive activity.

One possible mechanism is through its effect on the renin - angiotensin - aldosterone system (RAAS). The extract can inhibit the activity of renin or angiotensin - converting enzyme (ACE), which are key components in the RAAS and play important roles in regulating blood pressure. Additionally, it may also have a vasodilatory effect, which helps to lower blood pressure by reducing the resistance in blood vessels.

9. Cardioprotective Effects

Given its multiple effects on blood - related factors such as platelet aggregation, blood vessel protection, and lipid and blood pressure regulation, the Salvia miltiorrhiza root extract has overall cardioprotective effects.

It can protect the heart from damage during myocardial infarction by reducing infarct size. This may be due to its ability to improve blood supply to the heart muscle, reduce inflammation, and prevent platelet - mediated thrombosis in the coronary arteries. Moreover, it may also have a beneficial effect on cardiac remodeling after heart injury, which is important for maintaining normal heart function.

10. Anti - Diabetic Effects

Diabetes mellitus is a global health problem with increasing prevalence. The Salvia miltiorrhiza root extract has shown anti - diabetic effects.

It can improve insulin sensitivity in peripheral tissues such as muscle and adipose tissue. Insulin resistance is a key feature in type 2 diabetes. By enhancing insulin sensitivity, the extract can help to regulate blood glucose levels. Additionally, it may also have an effect on pancreatic beta - cells, which are responsible for insulin production. It may protect beta - cells from damage and promote their function, thereby contributing to the control of blood glucose.

11. Liver Protection

The liver is an important organ involved in various metabolic processes. The Salvia miltiorrhiza root extract has liver protection capabilities.

It can protect the liver from damage caused by toxins such as alcohol and drugs. In animal models, the extract has been shown to reduce liver enzyme levels, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), which are indicators of liver damage. It may also prevent liver fibrosis by inhibiting the activation of hepatic stellate cells, which play a crucial role in the development of liver fibrosis.

12. Anti - tumor Potential

Although more research is needed, the Salvia miltiorrhiza root extract has shown anti - tumor potential.

Some studies have reported that certain components in the extract can inhibit the growth and proliferation of tumor cells in vitro and in vivo. The mechanisms may involve inducing apoptosis (programmed cell death) in tumor cells, inhibiting angiogenesis (the formation of new blood vessels that supply tumors), and modulating the immune system to enhance the body's anti - tumor response. However, it should be noted that the extract cannot replace standard cancer treatment methods at present, but it may be used as an adjuvant therapy in the future.

13. Anti - Aging Effects

As mentioned earlier, the antioxidant activity of the Salvia miltiorrhiza root extract is closely related to its anti - aging effects.
