Eleusian Biosciences Corp., a Toronto based company, is focused on development of therapeutics for multiple pathological psychological diseases based on psilocybin plus N-Acetylcysteine (NAC) compounds. Eleusian is collaborating with a multidisciplinary team of scientists and physicians at the Miller School of Medicine at the University of Miami to develop effective therapeutics for the treatment of mTBI (mild traumatic brain injury/concussion) with PTSD or PTSD alone based on Psilocybin (the active ingredient of psychedelic mushrooms) and NAC. NAC has been shown to have efficacy in treating mTBI, particularly in reducing neuronal losses and also reducing impaired cognitive and neurological symptoms after injury to head.
