Taoist ways of food supplement include taking the bait, crossing the valley, externally applying elixir, washing drums and so on. Taoism believes that the human spirit is dominated by the body, while the body is guaranteed by food. In order to keep the spirit pure, we must eat less fireworks, and "stop stinking and stop eating and clearing the intestines" (Bao Puzi). The so-called "God Man" in "Zhuangzi", "Traveling around the world without eating grains, absorbing wind and drinking dew, riding clouds to descend dragons", is a model and pioneer of avoiding grains. The food gas unearthed in Mawangdui may be an ancient lost book handed down from the Warring States period. Pigu-is a cultivation method, that is, not eating whole grains, vegetables, meat and eggs and other daily foods. Broken grain is also called broken grain, broken grain, broken grain and stopped grain. This recipe says: "herbivores are good at walking but stupid, carnivores are strong and fierce, people who eat grains are smart but don't live long, and people who eat gas live forever." In other words, eating daily food can maintain daily life activities, but it can't live forever. He also said: "If you want to live, your intestines should be clear. If you want to live, you will not die. There is no me in your intestines. " In other words, daily food will leave harmful residues in the stomach, which will cause people to get angry and shorten their life. Taoism believes that there are three worms in the human body, also known as three corpses. According to the Taoist scriptures, the three corpses live in the spleen, which is the root of desire and the evil spirit that poisons the human body. If people don't eat whole grains and have no desire, then the three corpses can't survive in the human body, and the human body will eliminate evil spirits. Therefore, if we want to live a long life, we must break through the trough. The art of broken valley has a long history. "Historical Records Liu Hou" said: "Sick, no food." And "Bao Puzi Zhi Li": "In the past, Liu Hou ... he said,' In order to swim from red pine, I will give up human affairs. "So I repaired the guidance and lost the valley for a year." "Huang Qingting Interior" says: The land of hundred valleys, the beauty of five flavors, the evil of five flavors, and the sacred objects are zero. How to rejuvenate yourself? Why not eat too much gas and too delicate? ... so you wouldn't die in Huang Ning. People think that the technology of eating qi can reach the valley. The Seven Signs of Yun Qi (Volume 38) and the Tactics of Taking Qi from Zhongshan Jade Room to Kill Three Insects also say: If you eat a hundred valleys, evil spirits will survive, and the three insects will gather to cut through the five internal organs, making the abdomen flashy, the body fluid not flowing, the blood vessels impassable, the essence not frozen, the fetal soul not keeping the palace, and the ghost not closing the door, making people five. If you don't get rid of the smell of grain, you can't indulge in abstinence, then all the dead worms will die. If you kill three insects, ghosts haunt, soothe the soul, nourish the essence, shape the spirit and protect the world, you can't rely on it unless you are angry. Generally speaking, the way to go to the three corpses should be to fast first, thinking that you can't help the corpses without fasting first, and you can't make up for it without thinking about it. Then, use persuasion and fetal interest to achieve the goal. You don't eat grain, you don't eat food. On the basis of conviction, the exerciser reduced from three meals a day to two meals a day, and gradually became convinced by drinking water. At the same time, take some supplementary foods, such as pyrrosia, Atractylodes macrocephala, Rhizoma Dioscoreae, Rhizoma Polygonati, Jusheng, Poria, peanuts, jujube, chestnuts, walnuts, honey and so on. These foods are mostly used for medicine in traditional Chinese medicine, and are the best products for invigorating qi and blood, which have been included in herbal medicines in past dynasties. For example, it is recorded in the article "Those who eat grains eat stone reeds". Taiping Jing advocates training this skill, which is discussed in more detail in Bao Puzi. For example, "Bao Puzi's Essays" said: "Taking Atractylodes macrocephala, bait Polygonatum sibiricum and Yu Yu Liangwan every day for three days will make you more energetic, so you can afford a long trip and your body is very light." "Take licorice, Saposhnikovia divaricata, amaranth and other 37 kinds of small bags, swallow a stone the size of twelve eggs, and it will be fine in one hundred days. You will be more relaxed and your strength will be colored. According to some people's incomplete statistics, there are about 100 kinds of prescriptions scattered in Taoist books, all of which are good prescriptions for dietotherapy and nourishing. They are still used in clinic and have immeasurable good effects, especially accepted and welcomed by patients with chronic diseases. Taking food-also called taking the bait-refers to taking Dan medicine, which is a method of cultivation. Ge Hong's "Bao Puzi's Inner Chapter Fairy Medicine" quoted the "Four Classics of Shennong": "Taking medicine makes people live longer and become gods; ..... Chinese medicine nourishes nature and cures diseases and saves lives. " Ge Hong thinks: above the fairy medicine, it is cinnabar, followed by gold, followed by silver, followed by Zhu Zhi, followed by mica, followed by pearls, followed by realgar, followed by Taiyiyuying granules, followed by Huangshiren, followed by laurel, followed by stone brain, followed by sulfur ... followed by conifer resin, poria cocos, rehmannia glutinosa and Ophiopogon japonicus. So is Arturou. Volume 74 of the Seven Signs of Cloud says: those who are rich are the pearls of spring, those who win chicory are the spirits of autumn, those who are full of yang are the spirits of clouds, and those who are tuckahoe are the babies of crimson morning, with five flowers and smoke, and the three gases are refined, which can nourish and protect the spirit. They can be used well, they are immortal, and the elderly are rejuvenated. He also said: mica is sweet and non-toxic ... it can dispel pathogenic factors, protect the five internal organs, benefit the eyes, strengthen the muscles and tendons, continue to eliminate and tonify the middle warmer, treat five strains and seven injuries, reduce deficiency and replenish qi, and stop dysentery. Long-term service and smart people are suitable for prolonging life. The prescription also introduces many stories about taking medicine to become immortal. It is said that Han ate Acorus calamus 16, Prince Zhao ate cinnamon for 20 years, Xiangmenzi ate Schisandra chinensis 16, Chu Wenzi ate Rehmannia glutinosa for 8 years, asparagus, Poria cocos 18 and Lingyangzi ate Polygalae for 20 years, all of which became immortals. However, people who don't understand the medicine and medicinal properties of bait should not act rashly, otherwise, they may be poisoned and life-threatening. Drum washing-a basic skill that Taoist priests must do every day, prevailed in the world after Sui and Tang Dynasties. It includes several continuous processes: knocking teeth, stirring tongue, washing drums and swallowing. Fang said: "Every morning, put a handful of salt in your mouth, wipe your teeth with warm water and knock your teeth a hundred times, but after five days, your teeth will be tight." In the Qing Dynasty, Ma Qi's "The Fairy Classic" also said: "You will knock your teeth thirty-six times when you sleep, and you will never get worm teeth." In fact, knocking is not only done in the morning, but also after lunch and dinner. You can stand, sit and lie down, tapping about 48 times at a time. This is the tapping stage, which has the function of strengthening teeth and benefiting essence. After knocking on the door, gently stir the teeth with your tongue nine times along the outer upper, outer lower, inner upper and inner lower sides of the teeth in turn. This is the tongue stirring stage. Stir the saliva secreted by the tongue in the mouth for nine times to clean the inside of the mouth. This is the drum rinsing stage. Then swallow saliva slowly in nine times, which is the swallowing stage. This method is called "fetal food prescription" in the biography of Wang Zhen in the later Han Dynasty. Sun Simiao's Qian Jin Fang also said: "People take Yuquan orally and grind their teeth, which makes them strong and colorful. When the turbidity is discharged, the teeth are firm and Yuquan people spit in their mouths. Shan Chao took a bite of Tenshindon before he got up, but he still swallowed it and bit his teeth 27 times. This is called refining. " "Li Zhenren's sixteen-character longevity recipe" says: "If you suck it, you will lift it, and the air port will return to the navel." If you mention it, you will swallow it. Water and fire are incompatible. "If you do it for a long time, you will be ill for a long time", which is a very famous "sixteen ingots of gold work" in health care. Famous doctors in Ming and Qing dynasties all thought it was a good way to keep fit. In "Eight Records of Nourishing Harmony" written by Song Lian in the Ming Dynasty, the process of drum washing was introduced in detail, and its efficacy was pointed out: "If you do it for a long time, the five internal organs will not be inflamed by evil fire, and the limbs will be full of qi and blood, and all diseases will not be born, and the future troubles will be eliminated forever, and you will never get old." Modern medicine shows that this work can really protect teeth, clean mouth, sterilize, promote saliva secretion and strengthen digestion.
