The 45-year-old man was a stonemason who had been incidentally sprayed with rock dust from a saw 22 years ago. The subject presented with nodules and erythematous areas on his face and chin.

[The study on fingerprint of compound ginseng injection by powder X-ray diffraction].

Objective: To establish the fingerprint of "Compound Ginseng Injection", including Ginseng and Pericarpium Citri Reticulatae (Chenpi) raw material, their intermediate and injection by powder X-ray diffraction.

Method: Powder X-ray diffraction was used to analyze Ginseng and Chenpi raw material, their intermediate and injection, contrasted and analyzed the graphs to establish the fingerprint.

Result: The fingerprint of Ginseng and Chenpi raw material, their intermediate and injection was established.
