1. The onset of all diseases is due to the stagnation and obstruction of Qi and Blood, preventing their free circulation. Acupuncture is used to guide and unblock them, while moxibustion is used to warm the meridians. After treatment, proper care must be taken, avoiding raw, cold, sour, and slippery foods. If one fails to exercise caution, other diseases will inevitably arise.

2. When applying moxibustion to the head and limbs, sufficient heat and the arrival of Qi at the affected area are required for cure. However, since the tissues on the vertex of the head and the limbs are thin, simultaneous extensive moxibustion may deplete Qi and Blood in the lower body. It is advisable to pause intermittently or resume on alternate days, allowing the blood vessels to remain patent and the moxa heat to circulate freely. Accumulating an adequate total dose will naturally eliminate the disease. For instance, classical texts often mention inserting needles three *cun* or applying three moxa cones (*zhuang*) as general guidelines, not exhaustive methods. Since the skin on the hands and feet is thin, small cones with fewer *zhuang* are appropriate; whereas the abdomen and back have thicker flesh, larger cones with more *zhuang* are suitable. These should be judged by careful consideration. When moxibusting the back, familiarity with these principles is essential. The assessment of the "degree" of moxibustion (intensity/dose) should be based on the patient's constitution, age, and body type (emaciated or obese). For conditions such as chronic cold below the umbilicus, hernia, abdominal masses (*jia pi*), qi lumps, *fuliang* (a type of abdominal mass), and accumulated qi, large moxa cones should be used. Other medical texts state that the abdomen and back may tolerate up to five hundred *zhuang*. Limbs require only enough moxibustion to dispel wind pathogens and should not be excessive; the number ranges from seven to forty-nine *zhuang*, not exceeding this limit, and can be adjusted according to the patient's age. Points such as Juque (CV14) and Jiawei (CV15), although located on the chest and abdomen, should not exceed forty-nine *zhuang*. The moxa cone need not be large; a bamboo splinter tip can serve as a cone, applied directly over the vessel. Excessive size or number of cones at these points may cause permanent loss of heart power. Moxibustion on head points in excess may lead to mental depletion; excessive moxibustion on arm and leg points may deplete blood vessels, causing emaciation and weakness of the four limbs. Such depletion of spirit combined with physical wasting constitutes the exhaustion of true Qi.

3. Moxibustion is contraindicated in cases of fine and rapid pulses, and immediately after profuse sweating.

4. For individuals over thirty years of age, if moxibustion is applied to the head without also applying it to Zusanli (ST36), it may cause Qi to rebel upward and result in blurred vision, because Zusanli (ST36) has the function of descending Qi. For any disease, three *zhuang* should be applied to Zusanli (ST36) daily until the Qi descends properly.

5. Regarding moxibustion technique, one should generally start from upper parts and proceed to lower parts; treat Yang meridians first, then Yin meridians. Regarding acupuncture, it is generally preferred to perform procedures after noon rather than before noon.
