Yoga is so therapeutic for not only the body, but more importantly, providing therapy mentally and emotionally. I think it's wonderful to introduce it for PTSD as an alternative therapy rather than medicating these people. The same applies to everyone who has had trauma in their lives. I remember one time I was the doctors, the doctor treating me saw that I had fibromyalgia and compartment syndrome and she asked why I wasn't on antidepressants. When I asked her why did I need them, her answer to me was "well, don't you want to be happy?". I just laughed.
Instead of looking for a quick fix, medicating the symptoms and suppressing the problem, isn't it better to slowly over time deal with the issues in learning how to manage, overcome, accept whatever is going on and working therapeutically to release the trauma, even if it does take longer. We are so much stronger than we give ourselves credit for.
