First of all, for particles containing more volatile components, because high temperature is easy to cause the decomposition or loss of volatile components of drugs, it is best to take them with warm water, such as honeysuckle, houttuynia cordata, Schizonepeta tenuifolia, perilla, patchouli, mint, chrysanthemum and other drugs containing more aromatic volatile oil.
Secondly, granules are mostly composed of soluble drugs, and flavoring agents and excipients such as sugar and dextrin are added when making. Therefore, non-exterior-relieving drugs, especially tonics, should be taken with boiling water before taking them, so that they can be taken as syrup.
