Siwu Decoction is composed of four herbs: Angelica sinensis, Chuanxiong rhizome, Rehmannia glutinosa, and white peony root in a certain proportion. The main function is to nourish liver blood. Therefore, it is suitable for people with insufficient liver blood.

The clinical manifestations of insufficient liver blood include sallow complexion, pale claw nails, dizziness, numbness of hands and feet, easy cramping, scanty menstrual flow, light red color, and watery texture. Clinically, Siwu Decoction is suitable for all blood-related diseases such as anemia, anemia, excessive menstrual blood loss, etc.

The body constitution is hot and dry, and taking Siwu Decoction is prone to causing symptoms of internal heat. When taking traditional Chinese medicine, it is generally required to avoid eating spicy and greasy food. Spicy food is pungent in traditional Chinese medicine and can easily cause symptoms of internal heat. If your constitution is characterized by blood deficiency, heat and dryness, it is best to change the cooked rehmannia to raw rehmannia.

If you feel dizzy, you can first stop taking the medicine and observe. If you still have dizziness, it may be due to your own blood deficiency and inability to function, or a lack of nourishment. If the symptoms disappear after stopping the drug, it can be considered to be caused by the drug. It may be that the Rehmannia glutinosa is too greasy and the prescription lacks Qi-promoting medicine; it may also be caused by Chuanxiong. Chuanxiong can purify the head and nourish blood. It may be caused by discomfort during the process of qi movement, so the dosage can be reduced.
