not-panel-replicable

Key findings

  • The authors found preliminary clinical evidence suggesting possible efficacy in major depressive disorder and related symptoms.
  • The review proposed metabolism, inflammation, oxidative stress, and neurogenesis as possible targets.
  • Large randomized controlled trials were still needed.
