UNLABELLEDOBJECTIVE To study on vesicant characteristics of Uylabris and Seeds of Brassica Alb in crude herb moxibustion.

METHODSOne hundred and seventy-five healthy subjects were randomly divided into 5 groups. The vesicant rate, vesicant time and vesicant size and pain degree of different medicines or doses were observed. Results There were significant differences in the vesicant rate among the different doses groups of the same medicine (P<0.05), with no significant difference in the vesicant time (P>0.05); and there were significant differences in vesicant time among the different medicine groups (P<0.05). In the Uylabris group, the vesicant time was longer; the vesicant size in the medicine group of 0. 05 g each point was larger than that of the medicine group of 0.01 g each point (P<0.05); there were significant differences among the groups in the pain rate (P<0.05), and the pain rate was the highest in the 0.05 g each point of Seeds of Brassica Alb.

CONCLUSIONUylabris and Seeds of Brassica Alb have different vesicular characteristics, so in clinical application, application dose and time may be used for controlling the vesicant extent.
