Data expressed as mean ± sem. Group A = High dose sierrasil (n = 20), Group B = Low dose sierrasil (n = 21), Group C = Low dose sierrasil + cat's claw extract (n = 25), placebo n = 22. All groups displayed a significant change over the 8 weeks of the study (p < 0.001, ANOVA). Using the Wilcoxan Matched-Pairs Signed-Rank test the following descriptors reflect statistical significance from baseline; * p < 0.05, ** p < 0.01, *** p < 0.001.
