Fig. 2. Percentage of relaxation induced by the ethanol extract of Artemisia herbs (n=4). The penile corpus cavernosum smooth muscle that had been precontracted with 10−5 M of phenylephrine (Phe) was treated with 4 concentrations of Artemisia herbs. The submaximal penile contractile responses induced by the Phe solution were taken as 100%, and all subsequent responses to Artemisia herbs were expressed as a percentage of this value. Each point represents the mean±standard deviation of the percentages (*p<0.05 vs. 0.1 mg/mL, **p<0.01 vs. 0.1 mg/mL).
