Taoist ways of food supplement include taking the bait, crossing the valley, external elixir, drum washing and so on. Taoism believes that the human spirit is dominated by the body, and the body is guaranteed by food. To keep the spirit pure, we should eat less fireworks and "stop smelly, stop eating and clear the intestines" (Bao Puzi). Zhuangzi's so-called "God Man" is a model and pioneer of "traveling around the world without eating grains, sucking wind and drinking dew, and riding clouds to subdue dragons". The food gas unearthed in Mawangdui may be an ancient lost book handed down from the Warring States period. Bigu-is a cultivation method, that is, not eating whole grains, vegetables, meat, eggs and other daily foods. Broken grain is also called broken grain, broken grain, broken grain and stopped grain. This prescription says: "Herbivores are good and stupid, carnivores are strong and fierce, grain eaters are wise but not long-lived, and gas eaters are not dead." 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. " That is, daily food will leave harmful dregs in the stomach, which will make people 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 grains and cut off their desires, the three corpses can't survive in the human body, and the human body will eliminate evil spirits. Therefore, if you want to live a long life, you must break through the trough. The art of broken valley has a long history. "Biography of Historical Records" said: "(Sean) is weak and sick, that is, he is guided not to eat whole grains." And "Bao Puzi Zhi Li": "In the past, Liu Hou ... said,' I will abandon human affairs in order to swim from red pine. "Therefore, I trained and lost my valley for a year." "Huang Qingting Indoor Classic" said: The land of hundred valleys is pure, the five tastes are beautiful and evil, and the sacred objects are zero. How can I rejuvenate myself? Why not eat too much and be too angry? ... so you can't die in Huang Ning. It is believed that the skill of eating qi can be Doug's, and the book Seven Signs of Yun Qi (Volume 38) and The Skill of Taking Qi to Kill Three Insects also says: Eat a hundred grains, evil is flexible, and three insects gather. Penetrating the five internal organs and chiseling the six internal organs makes the abdomen flashy, the body fluid does not flow, the blood vessels are blocked, the essence is not frozen, the fetal soul does not keep the palace, and the ghost does not close the door, which makes people worry about five tastes, grow greedy, become old and aging, and wrinkle the skin. If you don't get rid of the smell of grains and indulge in abstinence, then the corpse worms will all die. If you kill three insects, ghosts haunt, soothe the soul, nourish the essence, shape the spirit and protect the world, unless you are angry, you are unreliable. 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 without thinking about it. Then use persuasion and fetal interest to achieve the goal. You don't eat whole grains, you don't eat grain. On the basis of persuasion, the exerciser reduced from three meals a day to two meals a day, and gradually persuaded by drinking water. At the same time, take some supplementary foods, such as pyrrosia, Atractylodes macrocephala, Rhizoma Dioscoreae, Rhizoma Polygonati, Jusheng, Poria, peanuts, Chinese dates, chestnuts, walnuts, honey and so on. These foods are mostly medicinal in traditional Chinese medicine, and they are the best products for invigorating qi and blood, and they have been included in herbal medicines in all dynasties. For example, it is recorded in the article "The grain eater eats reeds". This skill has been advocated in Taiping Jing, which is discussed in more detail in Bao Puzi. For example, "Bao Puzi Miscellaneous Articles" said: "Take Atractylodes Macrocephala, Bait Polygonatum and Yu Yu Liangwan every day, and within three days, you will have more energy, so you can afford to travel far and your body is extremely light." "Take 37 kinds of bags of licorice, divaricate Saposhnikovia root and amaranth, and swallow a stone the size of twelve eggs. If it doesn't heal for a hundred days, it will be refreshing and colorful. According to some people's incomplete statistics, there are about 100 prescriptions scattered in Taoist books, all of which are good prescriptions for dietotherapy and nourishing. At present, it is still used in clinic, with immeasurable good results, especially accepted and welcomed by chronic patients. Eating-also called bait-refers to taking Dan medicine, which is a method of cultivation. Ge Hong quoted Shen Nong's Four Classics in Bao Puzi's Inner Chapter Fairy Medicine: "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 five jade, mica, pearl, realgar, surplus grain of Taiyue jade, yellow seed in stone, laurel, seasonable, stone brain, sulfur ... followed by pine and cypress resin, poria cocos, rehmannia root and wheat. So is Arturou. Volume 74 of "Seven Signs of Clouds", the prescription 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 Yunling, and those who are tuckahoe are the children of crimson morning, with five flowers and three gases, which can nourish and protect the spirit. You can make good use of it, live forever and have a sense of security. He also said: mica is sweet and non-toxic ... it can dispel pathogenic factors, protect the five internal organs, benefit the eyes, reduce qi and strengthen tendons, continue to eliminate and tonify the middle warmer, treat five strains and seven injuries, reduce deficiency and replenish qi, and stop dysentery. Longevity and wise people are suitable for prolonging life. The prescription also introduces many stories about taking medicine to become immortal. It is said that Han finally took Acorus calamus 16, Prince Zhao took Guangxi for 20 years, Xiangmenzi took Schisandra chinensis 16, Chu Wenzi took Rehmannia for 8 years, Wenzhu took Poria cocos 18, and Lingyangzi took Polygalae for 20 years, all of which became immortals. But 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, drum washing and swallowing. Qian Jinfang said: "Every morning, put a twist of salt in your mouth, wipe your teeth with warm water and knock one hundred times. 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 suffer from worm teeth." In fact, slapping is not only done in the morning, but also after lunch and dinner. You can stand, sit and lie down, slapping about 48 times each time. This is the beating stage, which has the function of strengthening teeth and benefiting essence. After percussion, gently stir the teeth with your tongue nine times in turn along the outer upper, outer lower, inner upper and inner lower sides of the teeth, which is the tongue stirring stage. Rinse 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 "the prescription of fetal food" 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. In addition to turbidity, teeth are firm, and Yuquan people spit in their mouths. Before Shan Chao got up, he made a mouthful of saliva, but swallowed it and cut his teeth 27 times. This is called refining. " "Li Zhenren's Sixteen-character Wonderful Recipe for Longevity" said: "If you suck it, you will lift it, and the air port will return to the navel. Swallow when you mention it, and water and fire are incompatible. " "Doing it for a long time will prolong the illness", which is a very famous "sixteen ingots of gold" in health preservation. 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 blood and blood of the limbs will be smooth, 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.
