St. John's Wort is commonly used for what condition?

• A. Depression
• B. Anxiety
• C. Insomnia
• D. Hypertension

Answer: (A)

St. John's Wort is used mainly as an herbal option for depressive symptoms, especially mild to moderate depression. The active compounds in the herb, like hypericin and hyperforin, are thought to influence mood by altering monoamine neurotransmitters such as serotonin, norepinephrine, and dopamine, similar in idea to how some antidepressants work. Clinical studies have shown it can produce a modest to moderate reduction in depressive symptoms in many patients, and in some cases its effect is comparable to standard antidepressants for less severe depression. However, results vary and it’s not reliably effective for severe depression or bipolar disorder, so it’s not the go-to choice for serious cases. Safety matters too, because St. John’s Wort can interact with many other medications by increasing their breakdown in the liver, potentially reducing their effectiveness or causing adverse effects, which is why medical supervision is important if someone is considering its use. This makes it primarily associated with treating depression rather than conditions like anxiety, insomnia, or hypertension.
