Wei Yun, chief physician of Beijing Oriental Hospital, said that Compendium of Materia Medica
Jing Quan stone, also known as cold water stone, is cold in nature and enters the heart, stomach and kidney meridians. When combined with other drugs, it has the function of suppressing yang and clearing heat. Oral administration has a certain effect on heat syndrome such as hyperactivity of liver yang and disturbance of heart fire, and external use can treat ulcers. "There is no record of treating insomnia. There is no mirabilite in more than 400 kinds of Chinese herbal medicines commonly used in modern Chinese medicine, which is not commonly used in clinic.
Wei Yun said: Chinese medicine pays attention to syndrome differentiation and treatment, and there are many reasons for insomnia. It is obviously unscientific to say that insomnia can be cured only by adding cold water stones to pillows. Insomnia has both excess and deficiency. In the empirical study, the liver meridian is disturbed by damp heat and phlegm fire, and in the deficiency syndrome, the disharmony between heart and kidney and the deficiency of heart and spleen can all cause insomnia. Clinically, patients are often mixed with excess and deficiency, and it is impossible to solve all insomnia problems with one prescription.
As far as Hanshuishi is concerned, according to its medicinal properties and meridian tropism, it may have a certain effect on insomnia caused by heat syndrome, but due to its cold nature, it is not suitable for deficiency syndrome, and it will aggravate insomnia for people with qi deficiency and yang deficiency. If magnets are added to cold water stones, it will be even worse for patients with deficiency syndrome. Magnets can absorb human body heat and aggravate its cold.
