Typical manifestations of Shaoyin Disease (a disease caused by the invasion of the Shaoyin meridian by an exogenous pathogen) include a fine pulse, a desire to sleep (a state of hazy confusion, seemingly sleeping, seemingly waking up, not waking up), lying in a huddled position with a cold chill (fear of the cold), diarrhea (loose stools mixed with undigested food), coldness of the extremities, and even sweating out of the yang. Shaoyin disease is a condition characterized by deficiency of the heart and kidneys, with the patient suffering from a deficiency of yang in the heart and kidneys and an internal coldness in the yin. Shaoyin disease can be transformed from Sanyang disease, or it can be caused by external evils directly hitting Shaoyin (external evils directly invade Shaoyin through the muscle surface). Shaoyin disease is often a critical stage in the course of exogenous diseases, and is characterized by a generalized deficiency of cold, with the basic feature of “fine pulse, but wanting to sleep”. Due to the different causative factors and constitution of each person, although this disease is mainly characterized by deficiency cold, there are two types of coldness from yin to cold and heat from yang to heat. When the heart and kidneys are deficient in yang, the deficiency of yang generates cold, and when the heart and kidneys are deficient in yin, the deficiency of yin generates internal heat, and the disease is characterized by heat. When symptoms of Shaoyin Disease appear, you should seek medical treatment in time and under the guidance of a professional doctor to avoid delaying your condition.
