Sanbai decoction is a traditional Chinese herbal decoction, mainly composed of Atractylodes rhizome, White Poria cocos and White peony root. As for the question of grinding or boiling flour, it mainly depends on personal preferences and actual conditions.

1. Grinding flour: Some people like to use grinding flour to make Sanbai soup. By grinding the herbs into powder, the active ingredients of the herbs can be better released and are easier to carry and use. In addition, the dosage can be adjusted as needed after grinding to make the medicinal effect easier to absorb.

2. Boil soup: The traditional way of making soup is to add herbs to water and boil it for a period of time to dissolve the active ingredients of the herbs into the water. This method provides a richer herbal flavor, and the soup can be prepared in a thermos and consumed at any time.

Whether grinding or boiling is used, the choice should be based on personal needs and circumstances. If you like the original herbal taste, or if it is convenient to eat, you can try the grinding method. If you are more accustomed to drinking hot soup, cooked in advance, you can choose the cooking method.

No matter which method is used, it is best to consult a professional Chinese medicine practitioner or pharmacist for advice before use in order to obtain more accurate medication methods and dosages. At the same time, please pay attention to the safety and suitability when using herbal medicines and avoid excessive use or allergies to certain ingredients.
