The blood and qi of infants are weak, and their muscles are thin. If the regulation of cold and warmth is improper, the skin pores will open, allowing wind pathogenic factors to invade. The wind pathogen first lodges in the Shu points (Acupoints for dispersing pathogenic factors) and travels along the meridians, then enters the Fu organs (Yang organs) and Zang organs (Yin organs) following the circulation of blood and qi. Depending on where it lodges, specific diseases arise.
Among the Zang organs that receive the wind pathogen, only the Heart and Lung reside above the diaphragm, in hollow spaces, and their corresponding Shu points are also located superiorly. Therefore, wind easily invades these areas, causing illness. Symptoms include mental confusion and lethargy, loss of consciousness, twitching and spasms of the limbs, chest and heart fullness, shortness of breath, and excessive sweating. These conditions are particularly critical. Generally, the remaining Fu organs reside below the diaphragm in dense, overlapping areas, and their Shu points are located inferiorly; thus, wind rarely invades them, and they seldom suffer from such afflictions. Regarding wind invading the meridians, it causes numerous diseases. Here, we list those with documented cases.
Wind Spasm: This occurs when wind pathogenic factors damage the Yang meridians. It may result from joint dislocation or trauma, or an unhealed umbilical wound being exposed to wind, all leading to spasm. Symptoms include trismus (lockjaw) where the mouth cannot open, rigidity of the neck, back, and body, stabbing pain in the ears, and persistent mental confusion with loss of consciousness. The pulse is wiry (Xian), extending straight up and down. Although similar to Startle Epilepsy (Jing Xian), if the patient regains consciousness intermittently and the body becomes soft during episodes, it is Startle Epilepsy; if the patient remains unconscious frequently and the body is stiff and rigid, it is Wind Spasm. Sudden onset of generalized spasm indicates a fatal prognosis.
Wind Opisthotonos (Body bent backward like a bow): This is also caused by wind damaging the Yang meridians, resulting in hyperextension of the waist and back, preventing forward flexion, resembling a bowstring. While similar to Spasm disease, Spasm involves general rigidity, whereas this condition involves backward hyperextension, which distinguishes the two.
Wind Trismus (Lockjaw): The tendons of the Hand-Yang meridians connect to the jaw and cheeks, and the tendons of the Foot-Yangming Meridian ascend alongside the mouth. When wind pathogenic factors invade the tendons of the Yang meridians, causing joint stiffness and dysfunction, it results in an inability to open the mouth. Diagnosis reveals that a slow pulse indicates survival.
Wind Contracture and Paralysis: Wind pathogens mixed with cold and heat enter the meridians and bind to the tendons and vessels. When the tendons and vessels are affected by cold, the limbs contract and cramp; when affected by heat, the tendons relax, leading to motor impairment. Diagnosis shows that an urgent, fine, wiry pulse indicates tendon tension and contracture, while a slow and weak Spleen pulse indicates limb paralysis.
Wind Facial Paralysis (Deviation of Mouth and Eyes): Caused by wind pathogenic factors entering the tendons of the jaw and cheeks, leading to uneven tension in the meridians. This causes deviation of the mouth and eyes, inability to look straight ahead, and slurred speech. A floating and slow pulse indicates treatability. Another theory suggests that wind entering the ear through gaps during sleep can also cause facial deviation.
Wind Unconsciousness (Stroke Coma): Occurs when wind pathogenic factors first invade the Yin meridians, affecting the Zang organs. Symptoms include sudden loss of consciousness, gurgling sounds in the throat, tongue stiffness preventing speech, sweating followed by a soft body, and white discoloration under the eyes, beside the nose, and around the Renzhong point. These signs indicate treatability. If one side is black and the other red with foaming vomit, it is difficult to treat. If there is no sweating and the body is rigid, it leads to death.
