- Brief Summary
We examined the anti-stress effect of shaded white leaf tea (SWLT) on humans. Participants consumed the tea for 1 week prior to pharmacy practice, and continued for 10 days in the practice period. The state-trait anxiety inventory, an anxiety questionnaire, tended to be scored lower in the SWLT group than placebo, but other stress markers showed no differences. However, SWLT, which is high in caffeine and amino acids, suppressed depressant behavior in mice.
