How to Calculate the Amount of Water for Decoction with a Traditional Chinese Medicine Decoction Machine

When you first hold a package of traditional Chinese medicine, you're often puzzled about how much water to add for boiling. It can be quite麻烦. Now, with the advent of a specialized boiling machine for traditional Chinese medicine, we can save a lot of time and enjoy convenience. However, it's still important to consider how much water to add when using a traditional Chinese medicine boiling machine.

Prior to using the machine to decoct medicine, first fill the herbal slices into a special cloth bag, tie the bag securely, and soak it in a sufficient amount of clean and hygienic cool or warm water to allow the slices to absorb moisture fully, typically for about half an hour.

Next, consider the addition of water. The amount of water used to soak the herbal slices and the amount of plain water during the decocting process is related to the type of decocting machine, the composition of the herbal slices, and the yield of the medicine. The reference calculation formula for the amount of water added is as follows (the liquid from soaking the herbal slices should be included in the total water amount):

Combination Decoction Maker Water Amountml）=Absorb constant(ml/g)XHerb slice weight(g)+Anticipated dosage volume(ml)+Evaporation Constant(1ml/min)XCooking Time<Term absorption constant=2.0ml/gEvaporative Constant Volume Closed-Type Decoction Machine Water Addition(ml)=Absorb constant(ml/g)XHerb Slices Weight(g)+Anticipated liquid dosage to be achieved(ml)+No Chinese content provided.200(ml)<Now you should know how to properly add water to the decocting machine's absorption constant. The method of adding water to this decocting machine is for your reference only.
