通过中药方剂浸泡后水量确定药液量

The Determination of Liquid Quantity of Chinese Medicine Formula by Water Amount after Soaking

目的测定采用二次加水法浸泡中药方剂的每次加水量范围。方法通过对3个方剂不同的加水量和煎煮后药液量进行比较,确定药液量适宜时对应的浸泡后水量并推导出第一次加水量的合理值。再通过3个不同方剂验证所得浸泡后水量和第一次加水上限量是否合理。结果第一次加水量以不超过药面2 cm为宜,浸泡后水量参考为浸过药面1.3~2.0 cm。结论确定了中药方剂适宜浸泡后水量范围和第一次加水上限量,患者自行煎煮中药方剂时可作为技术依据。

Objective To determine the range of water added each time for soaking traditional Chinese medicine formula by the method of secondary adding water.Methods By comparing the different amount of water added to three prescriptions and the amount of liquid after decocting,the appropriate amount of water after soaking was determined and the reasonable value of water added for the first time was deduced.The water amount after soaking and the limit of the first addition of water were verified by three different formulas.Results It was advisable to add water less than 2 cm on the surface for the first time,and the reference water amount after soaking was 1.3~2.0 cm on the surface.Conclusion The suitable range of water amount after soaking and the limit of water added for the first time were determined,which can be used as technical basis for patients to decoct the Chinese medicine prescription by themselves.
