Herbal processing with Water
- Washing away mud and otherwise
- Softening to make it easier to cut
- Rinsing over running water to remove substances such as salts, smells, poisons

What does "Being decocted later" mean?
Some aromatic medicinal herbs with volatile components must be added after the solution of the other medicinal herbs has been boiled 10-30 minutes, and then boiled another 5 minutes or so
Why do you wrap some herbs before you boil them?
if decocted directly in water it will make the decoction turbid which is difficult to take orally
Why does one decoct or boil some herbs singlely?
due to them being precious or prevent them from being absorbed by other ingredients when they are decocted or boiled with other medicinal herbs (i.e. ginseng)
What is the purpose of melting some herbs first?
The method is mainly indicated for the medicine containing a lot of mucilage and easily soluble ones. If decocted directly together with other herb medicines in water, they will be deposited at the bottom of the pot or stick to the other ingredients and not be easily filtered
