鲁伯嗣说：所谓虚羸（身体虚弱消瘦），是由于脾胃功能不和，不能正常消化乳食，导致肌肤瘦弱；也常因大病之后，或呕吐、腹泻之后，脾胃依然虚弱，无法运化水谷精微所致。其中属于寒证的，表现为时常腹泻，嘴唇和口色青白；属于热证的，表现为体温升高，身体发热且肌肉略微发黄，这即是寒性和热性的虚羸病。对于寒证，主要使用木香丸治疗，夏季不宜服用，若出现此症，则少量服用。对于热证，主要使用胡黄连治疗，冬季不宜服用，若出现此症，则少量服用。伤寒病后出现的虚羸，主要使用竹叶汤治疗，平时可常服四君子汤，异功散、参苓白术散等方剂也可以服用。橘连丸长期服用可使身体丰满健壮，同时可配合服用肥儿丸。

Lu Bosi stated: "Xu Lei" (body weakness and emaciation) results from disharmony of the Spleen and Stomach, leading to an inability to digest milk and food, thereby causing emaciated muscles and skin. It may also occur after severe illness or following vomiting and diarrhea, where the Spleen and Stomach remain weak and fail to transform and transport grain qi. In cold-type cases, there is frequent loose stool, with bluish-white lips and mouth. In heat-type cases, there is elevated body temperature, feverish sensation, and slightly yellowish muscles; these constitute cold and heat Xu Lei. For cold types, Muxiang Wan (Aucklandia Pill) is the primary treatment; it should not be taken in summer, but if symptoms arise, a small dose may be administered. For heat types, Hu Huang Lian (Coptidis Rhizoma / Picrorhiza Root depending on context, here likely Coptis or Picrorhiza used for clearing deficiency heat) is the primary treatment; it should not be taken in winter, but if symptoms arise, a small dose may be administered. For Xu Lei following Shang Han (Cold Damage), Zhuye Tang (Bamboo Leaf Decoction) is the primary treatment. Regularly taking Sijunzi Tang (Four Gentlemen Decoction), Yigong San (Yi Gong Powder), or Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) are also suitable.
