It takes about 2-4 weeks of oral intake to see significant therapeutic effects. The reason why it takes so long is mainly related to the characteristics of the preparation of GUI Spleen Pill. GUI Spleen Pill belongs to a kind of proprietary Chinese medicine, which is less effective compared to tonics, so it causes the need to take it orally for a longer period of time to see obvious therapeutic effects, and proprietary Chinese medicine is especially suitable for the regimen of chronic diseases. It is mainly used to treat symptoms such as panic, insomnia and dreaminess, poor food intake, loose stools and diarrhea caused by deficiency of the heart and spleen. Many clinical conditions, such as palpitations, insomnia, irregular menstruation, etc., can be treated with Gui Shen Wan as long as they are identified as heart and spleen deficiency.
