1. Fewer half-moon marks: The fewer half-moon marks, the lower the energy, the colder the constitution, and the weaker the immunity. Traditional Chinese medicine says that Yang deficiency causes internal cold, which means the person is cold at heart and the body, hands and feet are particularly afraid of cold. If there are no half-moon marks, it does not mean that there is a disease. However, it should be noted that it is often not a disease but it is difficult to recover from a disease. Even a cold is difficult to recover from. People without half-moon marks often have indifferent sexual life due to lack of energy. 2. Abnormal half-moon marks can be divided into three types [1] Cold-base type. Those without half-moon marks are cold-base type. The cold bottom type indicates that the yang energy in the body is weak and the yin and cold are relatively strong. Such people have low organ function, slow movement of Qi and blood, are prone to fatigue, lack of energy, poor absorption function, pale complexion, cold hands and feet, palpitations, drowsiness, prone to colds, repeated colds, decreased energy, physical decline, and even worse Phlegm-damp stagnation, qi stagnation and blood stasis, phlegm-damp nodules, and tumors. [2] Hot bottom type: Those who even have half-moon marks on their little fingers, and if the half-moon marks enlarge, are all hot bottom types. The hot bottom type indicates that the human body has strong yang energy, strong internal organs, and good physical fitness. However, under pathological conditions, the yang energy is excessive and the functions of the internal organs are hyperactive. It can include flushing, irritability, irritability, constipation, irritability, dry mouth, large appetite, intolerance to cold, restlessness, and even high blood pressure, high blood sugar, and stroke. [3] Cold and hot type (yin and yang imbalance type) The boundary of the half-moon mark is blurred and the color gradually approaches the color of the carapace, which belongs to the cold and hot type or yin and yang imbalance type. The alternating pattern of cold and heat indicates that there are changes in the human body in which yin and yang are stronger and weaker. The changes in cold and heat can vary depending on different maintenance practices. For example, people with a hot type like to clear away heat and overuse cold substances, while people with a cold type like to remove cold and overuse warm substances. Improper medication use and excessive strain can also lead to changes in the balance of cold and heat. Early stage: The edge of the half-moon mark becomes unclear. Mid-term; half-moon marks begin to shrink. In the later stage; the half-moon marks gradually reduce and disappear. Physical fitness changes from hot to cold, energy declines and gradually leads to aging, frailty and illness. Many doctors focus on local heat-clearing and anti-inflammation, but do not pay attention to the half-moon scar, which is an important signal of physical fitness. The damage is too much or long-term use of medicine. The so-called "the more you take food and medicine, the weaker it becomes" because they ignore the changes in the half-moon mark. If the essence is sufficient, the growth, development and reproductive functions are normal, the energy is strong, the body is strong, and the body's immunity is strong; on the contrary, the essence is weak, the growth and development are poor or the body is aging, and the body's immunity is reduced. Therefore, the half-moon mark is an expression of human energy and is A window into health. "The essence is insufficient to make up for it with flavor." Replenishing energy depends on high-quality neutral proteins, such as milk, eggs, beans, fish, and black foods, seeds, and embryonic foods. As long as nutrition is ensured and maintenance is maintained, usually a half-month mark will be as long as one nail. Generally, the thumb grows first, followed by the index finger, middle finger, ring finger, and little finger after half a year. If you stay up late for a long time and have excessive nightlife, it will disappear quickly. As the saying goes: "If you have enough energy, you will be strong (half-moon marks on your feet), if you are weak, you will get sick (the half-moon marks will change color), if you are young, you will grow old (if you have less half-moon marks), if you have no more energy, you will die." Therefore, people without half-moon marks need to pay attention to nourishing their bodies even if they are temporarily free of illness. Especially when there are only half-moon marks on your thumb, your body is telling you that you have used "base oil" and you need to quickly add high-quality neutral protein and "oil". Therefore, we must maintain good living habits
