The present investigation evaluated the efficacy of a botanical supplement that delivered a concentrated dose of  Echinacea purpurea  (8 grams day −1 ). The participants were 13 apparently healthy, recreationally active college students (VO 2  max: 51 mL O 2 /kg∗min). The participants were provided with a 30-day supplementation regime. Data regarding maximum aerobic capacity was collected through pre- and posttesting surrounding the 30-day supplementation regime. The participants were instructed to maintain normal levels of physical activity and exercise during the experimental period. The levels of physical activity and exercise were monitored via the Leisure and Physical Activity Survey. The participants did not report any significant increases in aerobic physical activity or exercise during the supplementation period. Paired samples  t -test analysis did not reveal a significant difference in maximum aerobic capacity,  t (12) = 0.67,  P  = .516. Presupplementation maximum aerobic capacity ( M  = 51.0, SD = 6.8) was similar to postsupplementation values ( M  = 51.8, SD = 6.5). This study suggests that botanical supplements containing a concentrated dose of  Echinacea purpurea  is not an effective intervention to increase aerobic capacity of recreationally active individuals.
