In the past, many Chinese pharmacists did their own processing. Nowadays, it tends to be done industrially and most practitioners lack a detailed understanding of the subject. Nevertheless, practitioners need to understand that different processed forms available are used for different therapeutic purposes. For example, Gancao (Glycyrrhizae Radix), e.e. raw, unprocessed licorice, is used to clear heat, while honey-fried Gancao (Glycyrrhizae Radix) is used to boost qi. In the interests of providing safe treatments, it is important for practitioners to be aware of the processed forms of toxic medicinals since the processed forms are usually less toxic.

Aims of Processing

Elimination or reduction of toxicity, harsh effects and side effects

For example, Chuanwu (Aconiti Radix) can cause poisoning and should only be used when appropriately processed. Badou (Crotonis Fructus) causes diarrhea and is often used after the oil is removed or after the fruit is made into preparation known as a “frost.”
