Studies related to Sleep Latency and Valeriana officinalis

The Use Of Valeriana Officinalis (Valerian) In Improving Sleep In Patients Who Are Undergoing Treatment For Cancer: A Phase III Randomized, Placebo-controlled, Double-blind Study (NCCTG Trial, N01C5)

Supplementation of 450mg valerian root (0.8% valerenic acid) for 8 weeks as a sleep aid in persons undergoing cancer therapies noted that self-reported fatigue was less in the valerian group relative to placebo, and there appears to be no significant benefits to sleep quality (assessed by PSQI) despite improvement to both sleep latency and overall impairments to sleep (reduced from 84% to 60%)
