男子病新瘥。未平复而妇人与之交接得病者。名阳易。其妇人得病新瘥。未平复而男子与之
交接得病者。名阴易。若二男二女并不相易。所以呼为易者。阴阳感动。其毒度着于人如换

Generally, after a severe febrile disease such as Shanghan (Cold Damage), when Qi and Blood have not yet recovered, if sexual intercourse occurs too early, it not only causes the patient's condition to relapse due to overexertion (Lao Fu), but also leads to transmission through contact. If a male patient transmits the disease to a female, or a female to a male, it is like an exchange, hence named "Yin-Yang Yi" (Yin-Yang Exchange). The symptoms include feverish sensation, heat rushing to the chest, heaviness of the head making it difficult to lift, squinting eyes, spasticity and tightness of the four limbs, or acute pain in the lower abdomen, weakness so severe that one cannot turn over in bed, requiring assistance for movement. If not treated immediately, death ensues; some may survive for months but eventually die from gradual emaciation and exhaustion. It is also stated: Yin-Yang Yi disease refers to the condition contracted by a man or woman who has recently recovered from Shanghan but whose body has not fully stabilized, engaging in sexual intercourse with the opposite sex. Specifically, if a man recovers and engages in intercourse with a woman who then falls ill, it is called "Yang Yi"; if a woman recovers and engages in intercourse with a man who then falls ill, it is called "Yin Yi". Transmission does not occur between two men or two women. It is termed "Exchange" because Yin and Yang mutually influence each other, and the pathogenic toxin transfers to the other person, akin to swapping. The manifestations of this disease are heavy body, acute internal pain in the lower abdomen, sometimes drawing the external genitalia into spasm, heat rushing up to the chest, heavy head unable to be lifted, visual disturbances seeing spots, spasticity of the four limbs, abdominal pain, and clenched fists of hands and feet. These conditions often lead to immediate death. However, some do not die immediately; they suffer from acute internal lower abdominal pain, heat rushing to the chest, heavy head, sensation of joints separating, slack and weak meridians, emptiness of Qi and Blood, depletion of bone marrow, weak and short breathing, decreasing strength, inability to move in bed, dependence on others for standing and walking, and some may die after a prolonged period.
The poem states: Yang Yi and Yin Yi cause deep swelling and pain at the root; abdominal pain extending to the waist and hips characterizes Yin. In warm diseases, a restless pulse indicates recurring heat; when Yin and Yang intersect, uncontrollable sweating occurs.
Male patients suffering from Yang Yi and female patients from Yin Yi contract these conditions due to sexual desire shortly after recovery. This is also known as "Female Labor Relapse" (Nv Lao Fu); similar symptoms arise from emotional distress. Symptoms include heavy body, lack of Qi, acute lower abdominal pain, inability to lift the head or stand on feet, spasticity of limbs, separation of joints, visual spots, and heat rushing to the chest. In men, it presents as swelling of the genitals retracting inward and attacking abdominal pain; in women, it presents as internal urgency, back swelling, and pain radiating to the abdomen. If hands and feet are clenched and spasmodic, and the pulse deviates from the meridian pattern, the condition is incurable. With deficiency of Ying and Wei (Nutritive and Defensive Qi) and exhaustion of essence and marrow, accompanied by slight breathlessness and inability to move in bed, death follows after a long duration. Alas! The harm caused by external contraction of the Six Qi and internal injury from the Seven Emotions is indeed severe. A damaged pulse deviating from the meridian, beating once per respiration, indicates deficiency; a pulse deviating, beating three times per respiration, indicates excess. Formulas such as Shao Kun San (Burning Underwear Powder), Shu Fen Tang (Mouse Feces Decoction), Zhu Ru Tang (Bamboo Shavings Decoction), Gan Jiang Tang (Dried Ginger Decoction), Qing Zhu Ru Tang (Green Bamboo Shavings Decoction), and Dang Gui Bai Zhu Tang (Angelica and Atractylodes Macrocephala Decoction) should be selected according to judgment. For cases involving Yin-Yang intersection, if it is a Warm Disease, sweating methods must not be used; inducing sweat will cause high fever, delirium, and anorexia with a restless pulse, which is generally untreatable. If the pulse is floating and rapid, the exterior syndrome persists, and sweating may be reapplied. If the pulse is deep and solid, or there is delirium, it indicates stomach fullness and excess Yang, requiring purgation. For heat persisting after re-sweating, Guizhi Tang (Cinnamon Twig Decoction) is generally used; for re-purgation, Chengqi Tang (Gut-Draining Decoction) is used.
