Restoration of chronic-Delta 9-THC-induced decline in sexuality in male rats by a novel benzoflavone moiety from Passiflora incarnata Linn.

abstract：:Rodent models of chronic pain may elucidate pathophysiological mechanisms and identify potential drug targets, but whether they predict clinical efficacy of novel compounds is controversial. Several potential analgesics have failed in clinical trials, in spite of strong animal modelling support for efficacy, but there...
