The effectiveness for the amelioration of depression is derived mainly from the extract of Pinus densiflora. In studies using mice, free consumption of Sho-ju-sen containing this extract at 1%, 3%, and 10% for 21 days resulted in significant amelioration of the response rate at 1% and 3%. Additionally, both the response rate and % avoidance were improved at the 10% concentration. While Sho-ju-sen (10%) caused no significant effect following a 7-day intake, it ameliorated the response rate following a 14-day intake. The extract of Pinus densiflora was found to mildly improve the response rate.
