What are the effects and functions of Rhodiola rosea root?

As people in modern society pay more and more attention to their appearance, many friends will go to shopping malls to buy international cosmetics to make their skin look more hydrated and smooth, and at the same time delay their skin aging. In fact, many friends have seen the name of Rhodiola rosea root in the ingredients of international cosmetics, so what are the effects and functions of Rhodiola rosea root? In the next period of time, please learn with me.

1. Effects on the cardiovascular system

Salidroside can significantly reduce the left ventricular end-diastolic intraventricular pressure and blood pressure of rats in a short period of time, reduce the preload and postload of the heart, improve cardiac function, and can also significantly reduce various indicators reflecting the contractile performance of the myocardium and weaken the contractile performance of the isolated heart. Salidroside exhibits a bidirectional effect on isolated frog hearts, first excitatory and then inhibitory. Rhodiola rosea alcohol extract can significantly increase the arterial blood pressure of rats and show a certain dose-effect relationship. The alcohol extract can also reverse the decrease in blood pressure caused by phentolamine, and the effect on heart rate has no regular changes. Rhodiola rosea has a certain cardiotonic and vasoconstrictor effect. Salidroside has a protective effect on myocardial cells damaged by reoxygenation after hypoxia. It can maintain the normal beating frequency of myocardial cells after reoxygenation after hypoxia, reduce the release of LDH, and maintain the normal ultrastructure of myocardial cell membrane, myofibril, mitochondria, etc.

2. Effects on the Central Nervous System

Rhodiola rosea ethanol extract can counteract the memory impairment in mice caused by scopolamine and significantly improve the memory retrieval impairment caused by ethanol. Salidroside can enhance the excitability of the brainstem reticular system, stimulate the spontaneous potential activity of the cortical sensory-motor area, visual area and major subcortical structures, and enhance the potential changes in response to photoelectric stimulation. Rhodiola rosea can correct the content of the neurotransmitter 5-HT in the central nervous system that deviates from normal levels, which is an important condition for the body's overall sound function and improved endurance to adverse factors.

3. Impact on immune function

Rhodiola rosea can increase the percentage of T lymphocytes in the peripheral blood of mice, and significantly increase the weight and index of the spleen and thymus. Rhodiola rosea polysaccharide can reduce the peripheral blood Hb content of normal mice, and increase it in immunocompromised mice. It has no significant effect on the peripheral blood leukocytes and thymus weight of mice. It can promote the transformation reaction of spleen lymphocytes and the killing activity of NK cells in normal mice, and at the same time reverse the above indicators of immunosuppressed mice. Rhodiola rosea can regulate the specific and nonspecific immune functions of the normal human body under low temperature conditions, enhance cold resistance, and accelerate the establishment of cold adaptation.

The above paragraphs are what I introduced to you about the effects and functions of Rhodiola rosea root. I sincerely hope that my friends can study the above content carefully and gain more, so that they can have a more correct understanding of Rhodiola rosea root. And in daily life, we can better exert the efficacy of Rhodiola rosea root, thus bringing more benefits to our health.
