I've been taking 2 capsules (overall 520 mg) of St. Jonh's Wort for 5 days. Each capsule contains 0.7 mg of hypiricin and hyperforin not over 4.9 mg. How long does it take to work?
It needs to build up in your blood. So it might take a few weeks. If it's been a month and nothing's happening talk to your doctor. For now just give it some time.
