二症外相似，而治法实不同。虚损者，阴阳两虚也。劳症者，阴虚阳亢也。故虚损可用温补；若劳症则忌温补
而用清补也。
两症辨法，不必凭脉，但看人着复衣，此着单衣者，为劳症。人着单衣，此着复衣者，为虚损。劳症，骨蒸而
热；虚损，荣卫虚而热也。
凡人过劳，脉必浮大不伦，〔按之无力〕，若不安闲作息，必有吐血之症。法当滋补，方用∶
人参（三两） 白术（五两） 茯苓（三两） 熟地（五两） 山萸（四两） 当归（八两） 白芍（五两）
黄（五两） 麦冬（三两） 五味子（三两） 砂仁（五钱） 陈皮（五钱） 神曲（一两）
共为末，炼蜜为丸，每日早晚各服五钱。
〔此方乃补气、补血、补精之妙品也。有斡旋之力，可以久服滋人，不致有偏胜之祸也。〕
〔人有虚劳，未成劳瘵之症，〕而将成劳者，方用∶
熟地（一两） 地骨皮（五钱） 人参（五钱） 麦冬（五钱） 白术（一钱） 山药（三钱）
白芥子（三钱） 五味子（三分）
水煎服。
凡人右寸脉大于左寸脉，即内伤之症。不论左右关尺脉如何，以此方投之效验。
劳病既成，最难治者，盖必有劳虫生之，以食人之气血也。若徒补其气血，而不入杀虫之品，则饮食入胃，
只荫虫而不生气血也。若但只杀虫而不补气血，则五脏尽伤，又何有生理哉？惟于大补之中，加入杀虫之药，则元
气既全，真阳未散，虫死而身安矣。方用∶
人参（三两） 熟地（八两） 何首乌（八两） 地栗粉（八两） 鳖甲（一斤） 神曲（五两） 麦冬（五两）
桑叶（八两） 白薇（三两） 山药（一斤）
为末，将山药末打成糊，为丸，每日白滚水送下五钱，半年，虫俱从大便中出矣。
These two syndromes appear similar externally, but their treatment methods are actually different. Xu Sun (Deficiency and Damage) refers to a syndrome of deficiency in both Yin and Yang. Lao Zheng (Chronic Exhaustion Syndrome) refers to a syndrome of Yin deficiency with hyperactive Yang. Therefore, Xu Sun can be treated with warming tonification; however, for Lao Zheng, warming tonification is contraindicated, and clear tonification should be used instead.
To differentiate between these two syndromes, pulse diagnosis is not necessary; one only needs to observe the patient's clothing habits. If others wear thick clothes while the patient wears thin clothes, it indicates Lao Zheng. If others wear thin clothes while the patient wears thick clothes, it indicates Xu Sun. Lao Zheng is characterized by bone-steaming fever; Xu Sun involves heat arising from deficiency of Ying (Nutrient Qi) and Wei (Defensive Qi).
Whenever a person overexerts themselves, the pulse will inevitably be floating, large, and irregular, [feeling powerless upon deep pressure]. If they do not rest properly, hemoptysis (coughing up blood) will certainly occur. The treatment principle should be tonification. The prescription is as follows:
Renshen (Ginseng Radix et Rhizoma, 3 liang), Baizhu (Atractylodis Macrocephalae Rhizoma, 5 liang), Fuling (Poria, 3 liang), Shudi (Rehmanniae Radix Praeparata, 5 liang), Shanzhuyu (Corni Fructus, 4 liang), Danggui (Angelicae Sinensis Radix, 8 liang), Baishao (Paeoniae Radix Alba, 5 liang), Huangqi (Astragali Radix, 5 liang), Maidong (Ophiopogonis Radix, 3 liang), Wuweizi (Schisandrae Fructus, 3 liang), Sharen (Amomi Fructus Rotundus, 5 qian), Chenpi (Citri Reticulatae Pericarpium, 5 qian), Shenqu (Massa Medicata Fermentata, 1 liang).
Grind all ingredients into fine powder, mix with refined honey to make pills. Take 5 qian each morning and evening.
[This formula is an excellent product for tonifying Qi, Blood, and Essence. It has the power to harmonize and regulate, allowing for long-term use to nourish the body without causing harm due to excess.]
[For individuals with Xu Lao (Deficiency Exhaustion) who have not yet developed Lao Zhai (Consumption Disease/Tuberculosis),] but are on the verge of developing Lao Zheng, the prescription is as follows:
Shudi (Rehmanniae Radix Praeparata, 1 liang), Digupi (Bark of Lycii Cortex, 5 qian), Renshen (Ginseng Radix et Rhizoma, 5 qian), Maidong (Ophiopogonis Radix, 5 qian), Baizhu (Atractylodis Macrocephalae Rhizoma, 1 qian), Shanyao (Dioscoreae Rhizoma, 3 qian), Baijiezi (Sinapis Semen, 3 qian), Wuweizi (Schisandrae Fructus, 3 fen).
Decoct in water and take orally.
If the Right Cun pulse is larger than the Left Cun pulse, it indicates an internal injury syndrome. Regardless of the condition of the Guan and Chi pulses on either side, this formula will yield effective results when administered.
Once Lao Bing (Lao Disease) has fully formed, it is the most difficult to treat, largely because "Lao Chong" (parasitic worms associated with chronic exhaustion) must have arisen to consume the body's Qi and Blood. If one merely tonifies Qi and Blood without adding anti-parasitic herbs, the food entering the stomach will only nourish the parasites rather than generate Qi and Blood. If one only kills parasites without tonifying Qi and Blood, the Five Zang organs will be severely damaged, leaving no room for life. Therefore, within a major tonifying regimen, anti-parasitic herbs must be added. This way, Yuan Qi (Original Qi) will be complete, True Yang will not dissipate, the parasites will die, and the body will be safe. The prescription is as follows:
Renshen (Ginseng Radix et Rhizoma, 3 liang), Shudi (Rehmanniae Radix Praeparata, 8 liang), Heshouwu (Polygoni Multiflori Radix, 8 liang), Dili Fen (Dioscoreae Hypoglaucae Amylum/Bamboo Rice Powder, 8 liang), Biejia (Testudinis Carapax et Plastrum, 1 jin), Shenqu (Massa Medicata Fermentata, 5 liang), Maidong (Ophiopogonis Radix, 5 liang), Sangye (Mori Folium, 8 liang), Baiwei (Cynanchi Atrati Radix, 3 liang), Shanyao (Dioscoreae Rhizoma, 1 jin).
Grind all ingredients into fine powder. Use Shanyao powder mixed with water to form a paste as a binder to make pills. Take 5 qian daily with plain boiled water. After half a year, the parasites will be expelled through the stool.
