Answer 1

10) Option (a) is correct.(It accelerates the metabolism of some drugs.

Explaination:-

St.John's wort has the potential to interact with many drugs through three different mechanisms. One mechanism, induction of P450, accelerates the metabolism of many drugs causing loss of therapeutic effects. St.John's wort reduces the effects of digoxin because P-glycoprotein transports drugs out of tubular cells of the kidney and into the urine, greatly reducing digoxin levels. St.John's wort does not counteract the beneficial effects of CNS depressants. It can actually intensify the effects of Serotonin. St.John's wort is not known to increase the risk of bleeding.
