What condition is St. John's Wort primarily used to treat?

St. John's Wort is primarily used to treat depression, which is supported by numerous studies and clinical trials demonstrating its effectiveness in alleviating mild to moderate depressive symptoms. The active compounds in St. John's Wort, particularly hypericin and hyperforin, are believed to influence neurotransmitter activity in the brain, including serotonin, dopamine, and norepinephrine, which are crucial for mood regulation.

While it may be considered for other conditions such as anxiety or insomnia, its most robust and well-documented use is for depression. Some patients may experience improvement in mood and a decrease in depressive symptoms when using this herbal remedy, making it a popular choice for those seeking alternative treatment options for depression. Chronic pain is not a primary use, although some individuals may report an enhancement in overall well-being when their depressive symptoms are managed, which can indirectly affect their perception of pain.
