OBJECTIVE: To establish the quality standard for carbonizing drug characteristic of ginger carbon. METHOD: Gingers and different carbonized gingers were compared by the absorption of pigment, tannin content, pH, mouth's coagulation time and bleeding time. RESULT: The study resulted in the recommended carbonizing standard that the absorption capacity shall not be less than 7.50 mg x g(-1) for methylene blue, the tannin content shall not be less than 2.103 mg x g(-1), the pH shall be (5.50 +/- 0.10), and coagulation time and bleeding time shall be the shorter the better. CONCLUSION: The established assessment standard for carbonizing drug characteristic of ginger carbon is reasonable, easily operated and feasible.
