What are the functions of Scutellaria baicalensis Georgi and Codonopsis pilosula?
Hello, my darling.

Scutellaria baicalensis Georgi is also known as camellia root and soil gold tea root. Scutellaria baicalensis Georgi, a plant of Labiatae, whose roots are used as medicine. Has that effect of clearing away heat, eliminate dampness, cooling blood, preventing miscarriage, and removing toxic substance. Indications: fever, upper respiratory tract infection, cough due to lung heat, damp-heat jaundice, pneumonia, dysentery, hemoptysis, conjunctival congestion, restless fetus, hypertension, carbuncle and furuncle. The clinical application of Scutellaria baicalensis Georgi is superior to that of Coptidis Rhizoma, and it does not produce drug resistance.

1. Used for damp heat, chest tightness, thirst, diarrhea and jaundice. For damp-heat, it is equivalent to talc, Amomum villosum and Poria. For damp-heat diarrhea and abdominal pain, it is equivalent to Radix Paeoniae Alba, Radix Puerariae and Radix Glycyrrhizae. Jaundice caused by damp-heat accumulation can be equated with Chen Yin, Gardenia and Lophatherum gracile.

2. Used for fever, hyperpyrexia, polydipsia, cough due to lung heat, excessive heat bleeding, and toxic heat sores. For fever and high fever, it is often used with Coptidis Rhizoma and Gardenia Fructus. For cough due to lung heat, it can be used equally with Anemarrhena asphodeloides and Cortex Mori. For blood-heat rash, it can be combined with Radix Rehmanniae, Cortex Moutan and Folium Platycladi. For heat toxic sore, it can be used with honeysuckle and forsythia. In addition, this product has the function of clearing away heat and preventing miscarriage, and can be used for fetal movement restlessness. It is often used with Atractylodes macrocephala and bamboo shavings.

The main function of codonopsis pilosula is invigorating qi. Most suitable for daily fatigue and listlessness. People with lung qi deficiency and infirmity have a deep voice and feel short of breath, and they are panting when they are slightly active. People who focus on deficiency of spleen and stomach, weakness of limbs, loss of appetite and loose stool should also use Dangshen. Atractylodes macrocephala, Poria cocos and Radix Glycyrrhizae Preparata are commonly used in combination, which is Sijunzi Decoction, a famous prescription for invigorating qi and strengthening spleen. For patients with deficiency of both lung and spleen, Astragalus membranaceus, Atractylodes macrocephala, Poria, Pericarpium Citri Tangerinae, Angelica sinensis, Cimicifuga Rhizoma, Bupleuri Radix, Radix Glycyrrhizae Preparata, Ginger, and Jujube should be combined, which is the famous Buzhong Yiqi Decoction. Codonopsis pilosula can invigorate qi and nourish blood, which is one of its major characteristics. Therefore, people with deficiency of both qi and blood, shortness of breath, palpitation, fatigue, pallor, dizziness, loss of appetite, loose stool, and easy to catch a cold should also take Dangshen. Experiments show that Codonopsis pilosula can increase red blood cells and hemoglobin, so it is very beneficial for anemia patients to eat Codonopsis pilosula. Because of the leukopenia caused by chemotherapy and radiotherapy, taking Codonopsis pilosula can also promote leukopenia. Pharmacological Effects of Ginseng Ginseng has the functions of invigorating primordial qi, nourishing and strengthening, calming the nerves and improving intelligence, promoting fluid production to quench thirst, restoring pulse and resolving hard mass. Modern medicine generally believes that ginseng has a wide range of effects on the central nervous system, cardiovascular system, digestive system, immune system, endocrine system and urogenital system, which can improve people's physical and intellectual activities and enhance the nonspecific resistance of the body to harmful stimuli. The pharmacological activities of ginseng often have two-way effects due to different functional States of the body, so ginseng is a typical representative drug with "adaptogen"-like effects.

1 Effects on cardiovascular system Ginseng has extensive pharmacological effects on cardiovascular system. According to relevant data, intravenous administration can make the blood pressure of anesthetized dogs and rats decrease first and then increase, reduce arterial pressure resistance, slow down heart rate, enhance myocardial hypoxia tolerance, increase the threshold of supraventricular tachycardia caused by intracardiac electrode pacing, and protect anesthetized dogs' myocardium from ischemia-reperfusion injury. Animal experiments show that ginseng can significantly improve myocardial hypoxia tolerance. The anti-arrhythmia activity of ginseng is also very strong, which is consistent with the blood circulation of ginseng recorded in traditional Chinese medicine. Clinically, taking ginseng 3 ~ 5g orally can increase cardiac output, enhance myocardial contractility and slow down heart rate. Ginsenoside can promote the synthesis of phosphoric acid, increase the activity of lipoprotein enzyme, accelerate the hydrolysis of fat and chylous particles in blood vessels, and thus accelerate the metabolism of lipids. Ginseng can promote the excretion of cholesterol in feces, promote the transformation of cholesterol in blood and reduce cholesterol in blood. Therefore, ginseng has certain preventive and therapeutic effects on common senile diseases such as hypertension, atherosclerosis and coronary heart disease.

2 Effect on Diabetes Ginseng has no obvious effect on normal blood sugar, but it can regulate abnormal blood sugar level. Ginseng can improve the utilization rate of sugar, promote sugar metabolism, anti-lipolysis activity and restore the glucose tolerance of diabetes. "Compendium of Materia Medica" contains "Ginseng can cure diabetes". Clinical observation shows that ginseng can improve the general situation of diabetic patients and reduce the urine sugar of patients with mild diabetes. For critically ill patients, although it can not improve hyperglycemia, it can improve the general situation. After some patients use ginseng, the dosage of insulin can be reduced and the hypoglycemic effect time can be prolonged.

3 Anti-tumor effect Ginseng is not only a good rejuvenation agent, but also has a good anti-tumor effect. Clinically, ginsenoside and ginseng polysaccharide have certain therapeutic effects on gastric cancer and lung cancer, which can not only improve the symptoms, but also prolong the life of patients. Combined with other therapeutic drugs or radiotherapy, it can improve the curative effect and reduce the adverse reactions of chemotherapy and radiotherapy. After oral administration of ginseng preparation, the contents of white blood cells, red blood cells and hemoglobin in blood are increased, which promotes the hematopoietic function of bone marrow, has the effect of treating aplastic anemia and granulocytopenia, and can reduce the damage of light radiation to hematopoietic system. The anticancer effect of ginseng is to enhance the body's resistance to pathogenic factors and enhance the body's immune ability. Ginseng can be used as an adjuvant drug for preventing and treating cancer.

4 Effects on the Central Nervous System According to the Classic, the effects of ginseng are "nourishing the five internal organs, calming the mind, calming the soul, stopping fright, eliminating evil spirits, improving eyesight and enjoying intelligence". Modern pharmacological studies have confirmed that ginseng can enhance the excitement and inhibition of the higher nervous system, improve the function of mental work, adjust the dysfunction of cerebral cortex to restore it to normal, improve brain function and enhance memory. Clinically, taking "ginseng soaking suit" before labor can enhance the physical strength of pregnant women before labor and shorten the labor process. However, if the dosage is too much, it will easily lead to abnormal excitement, unable to sleep for a long time, and even lead to insomnia, which may be related to ginseng exciting the central nervous system.

5 Anti-aging effect The aging of human nerve cells is accompanied by the changes of cell membrane fluidity in cerebral cortex. Ginsenosides contained in ginseng can enhance the fluidity of cell membrane, thus delaying or delaying the aging of cerebral cortex and reducing memory damage in old age. Increasing membrane fluidity is an important index of ginsenoside's anti-aging mechanism. Ginsenoside can obviously inhibit the formation of lipid peroxide in brain and liver, reduce the contents of lipofuscin and serum lipid peroxide in cerebral cortex, liver and myocardium, and increase the contents of superoxide dismutase and peroxidase in blood. Ginseng can maintain the secretion function of brain gland hormone, promote cell formation, increase the content of immunoglobulin, enhance the phagocytosis of reticuloendothelial system, remove free radicals causing aging in the body and delay aging. In short, ginseng has the effects of preventing and treating diseases and prolonging life. Ginseng is a nourishing and strong medicine, especially suitable for the elderly whose organ function tends to decline in an all-round way. It has many functions, such as calming the brain, regulating nerves, stimulating blood vessels, stimulating appetite, promoting metabolism, restoring fatigue, enhancing liver detoxification, improving hematopoietic capacity of bone marrow, enhancing stress response, and promoting the biosynthesis of protein RNA and DNA. However, ginseng is a kind of medicine after all, and it is impossible to be "perfect". Improper use of ginseng can also cause a series of adverse reactions and side effects, such as excitement, irritability and insomnia. It will aggravate the symptoms of those with excessive pathogens. The participation of patients with gastric ulcer will aggravate the ulcer, so the abuse of ginseng is inevitable.
