夫血气者，所以荣养其身也。虚劳之人，精髓萎竭，血气虚弱，不能充盛肌肤，此故羸
瘦也。其汤熨针石，别有正方。补养宣导，今附于后。
《养生方》云∶朝朝服玉泉，使人丁壮，有颜色，去虫而牢齿也。玉泉，口中唾也。朝
未起，早漱口中唾，满口乃吞之，辄琢齿二七过，如此者三，乃止，名曰练精。
又云∶咽之三过，乃止。补养虚劳，令人强壮。
脾候身之肌肉，胃为水谷之海。虚劳则脏腑不和，脾胃气弱，故不能食也。
胃为腑，主盛水谷；脾为脏，主消水谷。若脾胃温和，则能消化。今虚劳，血气衰少，
脾胃冷弱，故不消谷也。
三焦者，谓上、中、下也。若上焦有热，则胸膈痞满，口苦咽干；有寒则吞酢而吐沫。
中焦有热，则身重目黄；有寒则善胀而食不消。下焦有热，则大便难；有寒则小腹痛而小便
数。三焦之气，主焦熟水谷，分别清浊，若不调平，则生诸病。
虚劳之人，血气虚竭，阴阳不守，脏腑俱衰，故内生寒冷也。其汤熨针石，别有正方。

《养生方·导引法》云∶坐地交叉两脚，以两手从曲脚中入；低头，叉手项上。治久寒
不能自温，耳不闻声。
血气，是用来滋养身体的。虚劳病人，精髓枯萎枯竭，血气虚弱，不能充盈肌肤，这就是消瘦的原因。对于汤药、热敷、针刺、砭石等治疗，另有专门的方剂。补益调养和导引功法，现在附在后面。
《养生方》说：每天早晨服用玉泉，能使人身体健壮，面色红润，去除寄生虫并坚固牙齿。玉泉，就是口中的唾液。早晨起床前，先漱口含住口中的唾液，待满口后吞咽，随即叩齿十四次，像这样重复三次，然后停止，这叫做“练精”。
又说：吞咽三次后停止。用于补养虚劳，使人强壮。
脾候应于身体的肌肉，胃是受纳水谷的脏腑（水谷之海）。虚劳会导致脏腑功能不和，脾胃之气虚弱，所以不能进食。
胃属于腑，主要盛纳水谷；脾属于脏，主要消化水谷。如果脾胃温和，就能消化食物。如今虚劳病人，血气衰少，脾胃寒冷虚弱，所以不能消化谷物。
三焦，分为上、中、下三部分。如果上焦有热，就会出现胸膈痞闷胀满，口苦咽干；如果有寒，就会吞酸且吐沫。中焦有热，就会身体沉重、目黄；如果有寒，就容易腹胀且食物不消化。下焦有热，就会大便困难；如果有寒，就会小腹痛且小便频数。三焦之气，主要负责腐熟水谷，分别清浊，如果不调和平衡，就会产生各种疾病。
虚劳病人，血气虚竭，阴阳失调，脏腑都衰弱，所以体内产生寒冷感。对于汤药、热敷、针刺、砭石等治疗，另有专门的方剂。补益调养和导引功法，现在附在后面。
《养生方·导引法》说：坐在地上交叉双脚，双手从弯曲的腿间穿过；低头，双手交叉置于颈项之上。用于治疗久寒导致身体无法自温，以及听力丧失。
Blood and Qi (Xue Qi) are what nourish the body. In patients with Xu Lao (Deficiency Consumption), the essence and marrow are withered and exhausted, blood and qi are weak, and they cannot fill out the muscles and skin; this is why they become emaciated. For treatments involving decoctions, hot compresses, acupuncture, and stone therapy, there are separate specific formulas. Tonifying, nourishing, and Daoyin (guiding and pulling exercises) methods are attached hereafter.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) states: "Taking Yuquan (Jade Spring/Saliva) every morning makes one vigorous, gives a good complexion, expels parasites, and strengthens teeth." Yuquan refers to saliva in the mouth. Before getting up in the morning, rinse the mouth with saliva, swallow it when the mouth is full, then click the teeth fourteen times (two sets of seven). Repeat this three times, then stop. This is called "Lianjing" (Refining Essence).
It also states: "Swallow three times, then stop." This tonifies and nourishes Xu Lao (Deficiency Consumption), making one strong.
The Spleen manifests in the muscles of the body, and the Stomach is the Sea of Water and Grain. Xu Lao (Deficiency Consumption) causes disharmony among the Zang-Fu organs, weakening the Qi of the Spleen and Stomach, thus leading to an inability to eat.
The Stomach is a Fu organ, primarily responsible for holding water and grain; the Spleen is a Zang organ, primarily responsible for digesting water and grain. If the Spleen and Stomach are warm and harmonious, digestion can occur. However, in Xu Lao (Deficiency Consumption), blood and qi are depleted, and the Spleen and Stomach are cold and weak, so grains are not digested.
Sanjiao (Triple Burner) refers to the Upper, Middle, and Lower Burners. If there is heat in the Upper Burner, there will be chest and diaphragm stuffiness and fullness, bitter taste in the mouth, and dry throat; if there is cold, there will be acid regurgitation and spitting of foam. If there is heat in the Middle Burner, the body will feel heavy and the eyes may turn yellow; if there is cold, there will be frequent bloating and indigestion. If there is heat in the Lower Burner, defecation will be difficult; if there is cold, there will be lower abdominal pain and frequent urination. The Qi of the Sanjiao (Triple Burner) is mainly responsible for cooking and ripening water and grain, and separating the clear from the turbid. If this is not balanced, various diseases arise.
In patients with Xu Lao (Deficiency Consumption), blood and qi are deficient and exhausted, Yin and Yang fail to maintain their proper positions, and all Zang-Fu organs decline, thus generating internal cold. For treatments involving decoctions, hot compresses, acupuncture, and stone therapy, there are separate specific formulas. Tonifying, nourishing, and Daoyin (guiding and pulling exercises) methods are attached hereafter.
The *Yangsheng Fang · Daoyin Fa* (Guiding and Pulling Methods) states: "Sit on the ground with legs crossed, insert both hands through the bent legs; bow the head, and cross hands behind the neck." This treats chronic cold that prevents self-warming and deafness.
Patients with Lao Shang (Labor Injury) have weak Spleen and Stomach function and cannot transform fluids, thus forming Tan Yin (Phlegm-Fluids). "Tan" (Phlegm) refers to saliva and mucus accumulating in the chest and diaphragm; "Yin" (Fluids) refers to water retention accumulating in the Bladder.
