Hi I do not think people can "get over" ptsd anymore than they decide to "catch" ptsd. I did not mean the green herb salvia in my post. I meant actual spit from the mouth has elevated levels of cortisol after trauma. I am sorry for the confusion. Some research suggests that high levels of cortisol at/near the time of the trauma are a predictor for which one of three people will develop ptsd; especially among women who were raped (strong corealation).
