Why should scutellaria baicalensis be wrapped and decocted?
The reason for decocting scutellaria baicalensis is: first of all, scutellaria baicalensis is small, light and does not sink in water. It is easy to float on the water surface when decocted in water and is difficult to be fully decocted. The amount of effective substances decocted is relatively reduced, and it is difficult to filter the medicinal juice. Secondly, the seeds of scutellariae are slightly sticky and easy to stick to the pan. The adsorption of the residue will cause the loss of effective ingredients, and the mouth will feel sticky and uncomfortable when taking the medicine, which can easily make the patient nauseous. In order to avoid the above problems, it is advisable to wrap and fry.
