How can I help client who has PTSD?

Began to research for PTSD and alternative care.

Aromatherapy, music, acupuncture, Physical Therapy, Occupational Therapy, Yoga, meditation, Food, counselor, and etc...

I Google "PTSD" and "Aromatherapy" because it is basic and easy to add with massage session.

It came up many websites and blogs, but this is the most interest website 

 "Healing Combat Trauma."
