discussion 4

The immunity refers to the function of the body immune system to recognize self and foreign matters and eliminate antigenic foreign matters through immune response so as to maintain the normal physiological balance of the body. The immunity is a self defense mechanism of a human body and is the capability of resisting external invasion and maintaining the stability of the internal environment of the body. It is widely believed that the health condition of the body is closely related to immune function, and when the immune function of the body is reduced or inhibited, the body resistance is reduced, the body constitution is deteriorated, foreign bacteria, viruses and other substances cannot be effectively recognized and eliminated, the incidence of diseases is increased, and the body often feels fatigue^[1]. The immunity of the human body is improved, and the human body is protected from being damaged,the development of functional herbal tea with high safety and immune enhancement is one of the hot spots of current researchers.

The traditional Chinese medicine holds that healthy qi is a basic substance for resisting exogenous pathogenic factors and preventing and treating diseases, maintains normal life activities of human bodies, leads the life activities of the human bodies and the diseases to return due to the exuberant decline and decay of the healthy qi, and is functional activities, disease resistance and rehabilitation capability of the human bodies. Su Wen (plain questions) includes that the healthy qi exists in the interior and the pathogenic factors cannot be dried. In this respect, the healthy qi of traditional Chinese medicine is reflected in the immunity of human body in modern medicine^[2]. The deficiency of healthy qi causes the pathogenic qi to enter the body, resulting in disorder of function and hypoimmunity. The traditional Chinese medicine has proved to have high safety and clinical effectiveness in long-term development, and the regulation and control effect on the immune system is continuously explored^[3-4]。

The astragalus root is mild in nature and sweet in taste, is rich in various compounds such as polysaccharides, saponins, alkaloids and flavonoids, and has the effects of tonifying qi and invigorating yang, consolidating superficial resistance and arresting sweating, inducing diuresis and relieving swelling, and expelling toxin and pus. Modern pharmacological research shows that astragalus root and its extract have obvious immunological regulation, antitumor, antioxidant and other pharmacological activity^[5-8]. Radix Codonopsis has effects of invigorating spleen and replenishing qi, invigorating spleen and benefiting lung, and can promote healthy qi and middle-warmer energy of human body. The research of codonopsis pilosula on the aspect of body immune regulation is extensive and deep. The Codonopsis pilosula polysaccharide has strong promotion effect on humoral immunity, can promote proliferation of mouse spleen B lymphocytes, improve phagocytic ability of mouse macrophages, and further adjust organism immunity function^[9-10]. The astragalus and codonopsis pilosula are combined to tonify qi, nourish spleen and stomach, and have the effects of enhancing immunity, expanding blood vessels, reducing blood pressure, improving microcirculation, enhancing hematopoietic function and the like. Can be used for treating lassitude, soreness of waist and knees, dizziness, amnesia, blurred vision, hyperhidrosis, and diabetes. On the basis, the research observes the immunoregulation effect of the astragalus strengthening tea on immunosuppressive mice.

CTX is commonly used for constructing animal models with low immune function or suppressed immune function, can obviously reduce the body mass of animals and influence cell factors related to peripheral immune organs, lymph organs and organism immunity^[11]. Peripheral lymph organ bagIncluding blood, lymphatic vessels and immunocompetent cells, the influence of the astragalus strengthening tea on the immune function of the body is observed by detecting the peripheral blood routine of a mouse in the research. Research results show that the astragalus root healthy-strengthening tea can effectively improve the blood WBC, RBC and PLT of immunosuppressed mice, relieve the inhibition effect of CTX on bone marrow, promote the recovery and progression of bone marrow hematopoietic function and improve the bone marrow hematopoietic function.

The immune organ is a basic place for exerting the immune function, the thymus and the spleen are important immune organs of the body, and the development conditions of the thymus and the spleen are closely related to the immune function of the body. Wherein, the spleen is an important peripheral immune organ in the body, has nonspecific and specific immune functions, and not only can be used as a place for the colonization of immune cells, but also can be used as a place for receiving antigen stimulation to generate immune response; the thymus, as a central immune organ, is the site where the body has an immune response after being stimulated by an antigen, and is the site where cells develop and mature. The increase of the weight of spleen and thymus organs represents the proliferation of lymphocytes in the organs, and the intensity of the immune response level of the organism is often reflected by the proliferation degree of the lymphocytes^[12]. Therefore, the thymus index and the spleen index can better reflect the development degree of immune organs and the function of immune cells, thereby further reflecting the strength of the immune function of the body^[13-14]. In the study, the influence of the astragalus strengthening tea on the organ index of a CTX-induced immunosuppressed mouse is detected. The results show that after the medicine treatment, the astragalus root healthy-strengthening tea has the most obvious effect of increasing the thymus index and the spleen index of a CTX immunosuppressive mouse model, and the improvement of the immune function of an organism is proved.

In summary, the research is based on an immunosuppressive mouse model, and the astragalus strengthening tea is found to have the functions of protecting and enhancing the immune function in vivo research. The astragalus root body resistance strengthening medicinal tea prepared by the process is safe and effective, has no toxic or side effect, can be taken for a long time, and is a promising medicinal tea capable of obviously improving the immune function.

Crowd observation

The basic research shows that the formula I of the astragalus strengthening tea has stronger protection and enhancement effects on the immune function of the immunosuppressive mouse body, and the effect is better than that of the astragalus strengthening tea with other formulas. Therefore, the effect of the astragalus root strengthening tea prescription I on people with low immunity is observed.
