St. John’s Wort is best known for its antidepressant effects. The active components, such as hyperforin and hypericin, are thought to increase the availability of mood-regulating neurotransmitters—serotonin, norepinephrine, and dopamine—by reducing their reuptake. This mechanism supports its use in mild to moderate depression, which is the condition it’s most commonly noted to help aside from any other uses. The other listed conditions (hypertension, asthma, osteoporosis) do not have established therapeutic benefit from St. John’s Wort in standard practice. It’s also important to remember that this herb can interact with many medications by inducing liver enzymes, potentially reducing the effectiveness of anticoagulants, birth control, SAMPLEimmunosuppressants, and some antidepressants, among others.
