1. It's time to take tonic. As early as the Tang Dynasty, Sun Simiao, a great medical scientist, once pointed out that the four seasons are indispensable for people over 50 years old. It is believed that there is no tonic season after middle age. Generally speaking, the time of tonic should master the following principles: seasonal tonic: choose different tonic drugs according to the characteristics of different seasons. For example, winter is mainly nourishing and warming, and autumn is mainly nourishing, because autumn is relatively dry, summer is mainly clearing and filling, and spring is mainly soft filling. Flat filling can be used all year round. Tonifying in winter: First, winter is the season when the Tibetan seal is imposed and the qi of hair growth begins to sprout. Tonifying in winter and preventing diseases in spring next year. The so-called winter supplement is to kill the tiger in spring. Second, from winter to around, the climate is cold, various activities are reduced, and people's metabolic activities are relatively low; At the same time, people have a good appetite and easily absorb various substances. Therefore, winter tonic is beneficial to the absorption of tonic. Third, most tonics are easy to deteriorate and should not be stored, and they are more likely to deteriorate when heated. From winter to around, the climate is cold, and general supplements are easy to store and make up for deterioration. Fourth, Chinese medicine is mostly warm, but in winter, it has higher requirements for human yang, consumes more, and needs warm tonic. Tonifying at any time: Some elderly people are weak, but winter tonic obviously cannot improve their weak state in a short time, and it must be supplemented for a long time, regardless of seasons. 2. The principle of supplementing: The general principle is that deficiency must be followed, whether it is physiological or pathological, as long as there is deficiency, it can be supplemented. The following points should be adhered to in specific use: long-term. Adhere to the principle of small, long-term, multiple and balanced, and achieve long-term flow. The exhaustion of the elderly is not caused in a short time, some are physiological, and some are caused by disease factors. Therefore, don't have the idea of wanting to get fat with a bite. Taking a large amount of tonic in a short time is not only ineffective, but also counterproductive. Only by adhering to the principle of long flowing water can we fundamentally improve our physical fitness. At the same time, we should realize that taking any tonic for a long time may lead to imbalance of the body, so we should make a comprehensive supplement based on the principle of maintaining balance. Personality. Insist on syndrome differentiation and supplement, make up its shortcomings, so that tonic drugs are targeted and vary from person to person. This is a very important principle. In daily life, it is often seen that friends recommend certain supplements to each other, but after eating them, some are effective, some are ineffective, and even have side effects. Why is this? The reason is that everyone's physique, physical condition and weak degree are different, and the natural tonic drugs chosen should also be different. In other words, the choice of tonic drugs must be individualized. Qi deficiency can replenish qi, and drugs such as astragalus and ginseng can be used; Blood deficiency can replenish blood, and drugs such as Radix Rehmanniae Preparata, Polygonum Multiflori Radix and Radix Angelicae Sinensis are used; Yin deficiency can replenish yin, and drugs such as Radix Adenophorae, Fructus Lycii and Radix Ophiopogonis are used; Yang deficiency can replenish yang, and drugs such as Semen Cuscutae, Fructus Psoraleae, Herba Epimedii and Eucommiae Cortex can be used. Deficiency of both qi and yin or deficiency of both qi and blood should be supplemented with both qi and yin to replenish qi and blood. Diversity. Adhering to the principle of comprehensive integration on the basis of syndrome differentiation and treatment is actually the integration of individuality, periodicity and seasonality mentioned above. Diversity includes at least two aspects: one is the diversity of content. Because people's physical condition is changing at any time, the content of health care products taken must also change, including seasonal changes. The second is the diversity of forms. Can take well-packaged health care products, but also can be dishes, food, snacks, tea and other forms. Individuality, periodicity and seasonality of taking health care products. Individualization means that the consumption of health care products varies from person to person. For example, some people's brain function is obviously decreased, their memory and learning ability are obviously decreased, their reaction is slow, and their concentration is difficult. You can choose health care products that have certain brain-strengthening and brain-nourishing effects. Others are obviously afraid of the cold and their hands and feet are not warm. Traditional Chinese medicine believes that it mainly belongs to yang deficiency, so we should choose warm and tonic health care products. However, some people are flushed, afraid of heat, irritable and thirsty, which belongs to yin deficiency and internal heat, so they should choose health care products with certain effects of nourishing yin and purging fire. Everyone's physique and physical condition are different, and their forms of expression are different. The choice of health care products is naturally different. Don't be indiscriminate and choose at will. This is the individual principle that should be paid attention to when choosing health products, and it is also the most important principle. The so-called temporality means that the use of health care products must be adjusted and stopped at any time according to factors such as human body's physical condition, climate change and environmental change. This is a principle that must be followed during taking health care products. People's physical condition is changing at any time. If you have a cold, fever, diarrhea or other problems during taking health care products, you should temporarily stop using health care products. Even if health care products have a great effect on it, it should be so. Because during the cold, the treatment is mainly to dispel evil spirits, such as taking health care products at the same time, one is waste, and the other is fear of staying indoors, which is not conducive to the treatment of colds. Similarly, diarrhea should be stopped when it occurs. Wait until the cold or diarrhea is over, and then start taking related health care products. Changes in seasonal climate and geographical environment will also cause changes in people's physical condition, and the use of health care products should also be adjusted. The so-called seasonality is one aspect of the principle of temporality. The climate change in spring, summer, autumn and winter is very obvious, which has a great influence on the human body. People's health care should also be adjusted with the change of seasonal climate. The choice of health care products must also be different with the change of seasonal climate. Like in rainy summer, on the one hand, the temperature is high and the climate is hot; On the other hand, there is constant rain and high humidity. It is very uncomfortable for people to live in the sun and sweat in the sun. Many people have the so-called "summer", which is due to the humid heat caused by the seasonal climate and the disharmony of spleen and stomach functions, leading to loss of appetite, mental fatigue, heavy limbs, sticky mouth and thick and greasy tongue coating. Therefore, in summer, we should properly choose health care products with the functions of regulating spleen and stomach and eliminating dampness. Such as mung beans and rice grains. However, in autumn, the weather is cool and dry, and it seldom rains. The human body often has some dry manifestations, especially the lungs. Therefore, in autumn, we should properly choose health care products with the function of moistening lung and dryness, such as lily and tremella.
