ABSTRACT
<p><b>OBJECTIVE</b>To establish the quality standard for carbonizing drug characteristic of ginger carbon.</p><p><b>METHOD</b>Gingers and different carbonized gingers were compared by the absorption of pigment, tannin content, pH, mouth's coagulation time and bleeding time.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>The established assessment standard for carbonizing drug characteristic of ginger carbon is reasonable, easily operated and feasible.</p>
