Yet Tsunade could not heal the psychological trauma she suffered with Jutsu. Psychological trauma is caused by a traumatic experience, not necessarily caused by a physical injury you can just "heal".

It's more likely she just healed the organ (the brain) from the immense stress it suffered, allowing both Kakashi and Sasuke to wake from their coma's.

As you can see with Sasuke, the dude was definitely not healed from the damage done psychologically. The dude needed a healthy dose of drugs and therapy.

I seriously doubt they even had anti-depressants or cognitive behavioral therapy in the Naruto universe. Either way the only way to effectively "cure" you of your trauma, or rather, have you "accept and move-on" from it, is to change the thought patterns disturbing you.

I doubt Tsunade had the ability to alter brain chemistry to manually change the thought process, or else she would've done it before she had ever met Naruto. She got over her PTSD by facing her trauma and moving on from it, not by touching her own forehead.

Unless Tailed Beasts can alter the person's thought process, I seriously doubt it can heal psychological trauma. For all we know, it just speeds up the natural healing process at an exponential rate.

Traumatic memories just can't be healed mechanically that easily.
