Figure 5. Effect of Artemisia argyi water extract in cardiac function. (A) Weight of the control and the treatment group monitored periodically. Artemisia argyi water extract was given with drinking water; intake levels were measured in the treatment group and compared with the control group to avoid weight loss due to dehydration. (B) Echocardiography was done to monitor the cardiac function of the aged subjects with/without treatment. Echocardiogram of the aging animals 4 weeks after treatment showed significant improvement in cardiac function.
