Living a traumatic experience favors the persistence of fear associated with an aversive stimulus, known as fear conditioning. Scientists in the US and Spain have now found that such an effect, in mice, can be suppressed with a single dose of 7,8-Dihydroxyflavone, a type of flavonoid which boosts the ability to acquire new emotional behaviors. Researchers believe that the drug could also be used as an effective treatment of post-traumatic stress, panic and phobia disorders in humans.
