The scorpion, scutellaria, paeonol, and red peony in the heat-clearing medicine also have the same effect.
Second, reduce the excitability of sympathetic adrenal nerves
Various cold and cold medicines can reduce the heart rate of animals to a lesser extent, reduce the amount of adrenaline excretion in urine, reduce the activity of dopamine p-hydroxylase (DBH) involved in the synthesis of catecholamines, and reduce the secretion of 17OHCS in urine. Decreased, reduced oxygen consumption, and reduced excitability of sympathetic adrenal nerves. Its representative drug is Zhimu.
Third, improve the body's immunity
It has been found that some heat-clearing agents have good anti-infective effects, such as antibacterial and antiviral effects, and enhance the functions of both body-specific and non-specific immunity. Rehmannia glutinosa, paeonol, red peony and gentian can increase the number of T lymphocytes and enhance their functions; berberine, astragalus, dandelion and honeysuckle can promote the transformation of lymphocytes; paeonol and red peony can enhance humoral immunity; , rhino horn, raw land, paeonol, red peony, honeysuckle, wild chrysanthemum, big green leaf, gentian, Prunella vulgaris, Jin Qiaomai can enhance the function of phagocytic cells; Houttuynia can promote the phagocytic ability of white blood cells, Andrographis can enhance Lysozyme activity; Artemisia annua can induce interferon. The spur of the rheumatism can promote the phagocytic function of the reticuloendothelial system, enhance its ability to phagocytose foreign bodies and antigens, and increase the concentration of antibodies in serum. According to the functions of these traditional Chinese medicines, appropriate Chinese medicines can be administered to livestock and poultry to improve the body's immunity and prevent the occurrence of stress reactions.
Fourth, improve local blood circulation
Blood-activating and stasis-removing drugs can improve microcirculation, which has the following effects: Firstly, it has an indirect effect due to improved blood flow characteristics (concentration, viscosity, agglutination and aggregation), resulting in slow flow of blood. Acceleration; Secondly, improve the microcirculatory vascular morphology, which is characterized by the release of microvascular spasm, reduce the stagnation and accumulation of red blood cells in the circulation, reduce microvascular permeability, and reduce exudation around the microvessels, such as Chuanxiong, Salvia, Puhuang, safflower, Angelica and motherwort have similar effects.

Some Chinese medicines have the effect of protecting the mucosa. Rehmannia, Codonopsis, paeonol, rhubarb and other traditional Chinese medicines can be used to quickly protect the mucous membranes, so that the stimulating substances can not stimulate the mucosa.
