Salvation Revelation

Researchers at Harvard and McGill University are working on an amnesia drug that blocks or deletes bad memories.

In a new study, published in the Journal of Psychiatric Research, the drug propranolol is used along with therapy to dampen memories of trauma victims. 

Researchers treated 19 accident or rape victims with an early form of the amnesia drug for ten days, during which the patients were asked to describe their memories of the traumatic event that had happened 10 years earlier.

A week later, they found that patients given the amnesia drug showed fewer signs of stress when recalling their trauma.
