[Primary study on quality standard of carbonizing drug characteristic of ginger carbon].
OBJECTIVE
To establish the quality standard for carbonizing drug characteristic of ginger carbon.


METHODS
Gingers and different carbonized gingers were compared by the absorption of pigment, tannin content, pH, mouth's coagulation time and bleeding time.


RESULTS
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.


CONCLUSIONS
The established assessment standard for carbonizing drug characteristic of ginger carbon is reasonable, easily operated and feasible.
