The more i see of this drug the more i want to see it tamed and deeply studied. The vomiting is easily eliminated and is not a real problem.
We have covered many of the other applications ourselves.
After their drink, the participants sat in a quiet, dimly lit room. Physicians used standard clinical questionnaires to track their depression symptoms. Improvements were seen in two or three hours (though the psychedelic effects of an oral dose take around five hours to wear off) — a rapid effect, as conventional antidepressants can take weeks to work. The benefits, which were statistically significant, continued to hold up in assessments over the next three weeks. Three of the participants vomited, a common side effect of ayahuasca, but otherwise the procedure was well tolerated, Hallak says. 
Neuroimaging of the brains of the participants eight hours after ingesting ayahuasca revealed increased blood flow in areas of the brain whose diminished activation is usually associated with depression and increased activation is commonly associated with antidepressant effects.
The researchers attribute the antidepressant effects of ayahuasca to DMT, the principal psychoactive ingredient in ayahuasca, as it is an activator of serotonin receptors in the central and peripheral nervous systems.
