Whether taking Chinese medicine for sleep will harm the liver depends on whether the medicine is suitable for the symptoms and the time of taking it. If the patient follows the doctor’s instructions and takes the herbal medicine for sleep, there is usually no damage to the liver; if the patient takes the herbal medicine for sleep on his/her own and takes it for a long time, it may aggravate the burden on the patient’s liver and cause damage to the liver. Insomnia belongs to the category of insomnia in Chinese medicine. According to different identification, different medicines can be taken to relieve it. If the insomnia is caused by liver fire disturbing the heart, gentian diarrhea can be taken. If it is caused by phlegm-heat disturbing the heart, Huanglian Wengguan Tang can be taken. If it is caused by deficiency of the heart and spleen (weakness of the heart and spleen), then take Gui Spleen Tang. If there are symptoms of insomnia, it is recommended to consult a doctor for scientific treatment after identification by a professional doctor.
