Now everyone attaches great importance to health care. However, under the premise of health, everyone wants to stay young forever. The following are some commonly used traditional Chinese medicines for health preservation. Polygonum multiflorum Thunb. The song dynasty's "Kaibao Materia Medica" called it "long service will strengthen bones and muscles, benefit essence and prolong life". Modern research has found that Polygonum multiflorum Thunb can promote the growth of nerve cells and has an auxiliary treatment effect on nervous system diseases such as neurasthenia. It can also regulate serum cholesterol, reduce blood sugar and improve the ability of hepatocyte to transform and metabolize cholesterol. Polygonum multiflorum Thunb also has a good antioxidant effect. According to Shennong's Classic of Materia Medica, Ganoderma lucidum can "tonify liver-qi, soothe the nerves and settle down" and "keep fit for a long time and prolong life". Modern research has confirmed that Ganoderma lucidum can regulate the functions of nervous system, respiratory system and cardiovascular system, and has the functions of immunomodulation, scavenging free radicals and balancing metabolism, which directly affects the aging process of human body. Cordyceps sinensis is what we often call Cordyceps sinensis, which is a combination of insects and strains. Cordyceps sinensis has been highly praised by people in recent years because of its good health care function. Chinese medicine believes that Cordyceps sinensis can tonify kidney and essence to treat kidney deficiency, and can tonify lung qi to treat fatigue and cough. Therefore, Cordyceps sinensis is considered as a good product for health preservation and nourishing. However, due to its harsh requirements on the growth environment, it is temporarily impossible to cultivate artificially, so the price remains high. Although its nourishing effect is very good, it has to be ranked last because the price is not close to the people. Lycium barbarum is sweet, flat, nourishing liver and kidney, benefiting eyesight and resisting aging. It is not suitable for those with exogenous pathogenic heat, spleen deficiency and dampness, and diarrhea; Lycium barbarum has a strong warming effect, which is not suitable for people with high blood pressure and short temper, or people who usually eat more meat and blush. People who have a cold, fever, inflammation and diarrhea had better not eat it. Yam strengthens the spleen and stomach and helps digestion: Yam contains amylase, polyphenol oxidase and other substances, which is beneficial to the digestion and absorption function of the spleen and stomach. Tonifying kidney and replenishing essence: Yam contains various nutrients, which can strengthen the body, tonify kidney and replenish essence. Benefiting lung and relieving cough: yam contains saponin and mucus, which has the function of lubricating and moistening dryness, so it can benefit lung qi, nourish lung yin and treat lung deficiency, excessive phlegm and chronic cough; Lowering blood sugar: Yam contains mucin, which can lower blood sugar. Longevity: prevent heart disease, and achieve the effect of benefiting the heart, calming the nerves and prolonging life. Anti-hepatic coma: In recent years, yam has been found to have sedative effect and can be used to resist hepatic coma. Ginseng Ginseng has the functions of invigorating primordial qi, promoting fluid production, calming nerves, invigorating spleen and lung, stimulating nervous system, improving immunity and resisting aging. People who are physically strong take it for a long time, or take too much ginseng, they will be thirsty and even have nosebleeds. Ginseng is a tonic, which is always good for the body. This is wrong. Whether it is red ginseng or dried ginseng, it should be done step by step, not too fast or too much. In addition, we must pay attention to seasonal changes. The weather is cool in autumn and winter, and the food is better; If it is hot in summer, it is not suitable for eating. Avoid eating radishes and drinking tea after taking ginseng. Ginseng should not be eaten with grapes. Grape contains tannic acid, which is easy to combine with protein in ginseng to form precipitation, which affects absorption and reduces drug efficacy. The daily dosage is 5 ~ 10g. Sanqi Sanqi is often used to prevent and treat cardiovascular and cerebrovascular diseases such as beauty, freckle, hypertension, hyperlipidemia, heart disease, angina pectoris, coronary heart disease and cholesterol. Panax notoginseng is very suitable for daily health care. Notoginseng does have a remarkable effect. If you eat Sanqi for about 4 months, your body function will change to some extent. You can drink it directly in water. Once a day, it works very well in the morning and evening, which is the best time for human body to absorb. Angelica sinensis can promote blood circulation, replenish blood, regulate menstruation, and make skin shiny and ruddy, which is most suitable for daily maintenance of women. Applying face can promote blood circulation and lighten spots, promote skin metabolism, and make skin tender and shiny. Therefore, it is not an exaggeration to call angelica a "good medicine for enriching blood" and an "anti-aging beauty treasure". Usage: Use a spoon to stir coffee, one spoon at a time, once or twice a day. After getting used to it, it can increase the weight of Astragalus membranaceus, invigorate qi and refresh oneself, and enhance immunity. It is mostly used for people with qi deficiency. It has a very positive effect on protecting the liver. If it is qi deficiency, the most commonly used compatibility is Radix Astragali, Radix Codonopsis, Radix Pseudostellariae and Ginseng; If it is blood deficiency, it is most appropriate to add angelica; If it is yin deficiency, adding some medlar is also a good match. Tremella tremella contains a variety of amino acids, which can relieve dry and itchy skin. Tremella fuciformis is flat and non-toxic, which not only has the effects of invigorating spleen and appetizing, but also has the effects of invigorating qi and clearing intestines, nourishing yin and moistening lung. In addition, tremella can also enhance human immunity and enhance the tolerance of tumor patients to radiotherapy and chemotherapy. Now people in many places have begun to pay attention to health preservation. Although China has a saying that "medicine and food are homologous" since ancient times, we should be cautious when choosing food, which varies from person to person and from time to time, and pay attention to the method and quantity of food. It must be used under the guidance of a doctor, and must not be eaten without authorization or at will, so as not to cause unnecessary trouble.
