Consumption of rescue medication (paracetamol) for the study duration. Results for placebo (blue column, n = 19), high dose sierrasil (green column, n = 19), low dose sierrasil (red column, n = 20) and low dose sierrasil + cat's claw extract (orange column, n = 23) groups are expressed as mean ± sem. There was no significant difference in rescue medication use between the various groups, although a trend for less paracetamol consumption was evident in both the high dose sierrasil and low dose + cat's claw groups which approached significance (p = 0.119 and p = 0.101 vs placebo respectively).
