In patients with more severe illness the results were not so favorable. Neither study in moderate to severe depression differentiated SJW from placebo, tempering the generally positive findings observed in the studies of mild-to-moderate depression. It had been anticipated that the two large, rigorously conducted U.S. studies in more severely ill patients would help resolve the lingering questions regarding the efficacy of SJW, but the negative findings probably raised more questions than answers.Following release of these findings, much speculation ensued regarding what factors might have contributed to the poor results (e.g., low assay sensitivity, study design issues, treatment resistant populations, or sponsor bias). The general lack of any clear trends for SJW efficacy in both studies suggests that it simply is not effective
in more severely depressed patients.the lone long-term SJW relapse-prevention study also did not produce a statistically significant difference between SJW and placebo on the primary endpoint
