In addition to its use in treating depression, what other condition is St. John's wort used for?

St. John's wort is primarily known for its effectiveness in treating mild to moderate depression, but it is also utilized for various other conditions, including sleep disorders. This herb is believed to have a calming effect, which may help alleviate symptoms associated with conditions like anxiety and sleep disturbances. As a result, it may improve overall sleep quality and help individuals who struggle with insomnia or restlessness as a symptom of their underlying mood disorders.

The other options listed do not have a strong association with St. John's wort. Chronic pain treatment typically requires different classes of medications and modalities, while the herb is not officially recognized for managing stroke risk or directly aiding in weight loss. Thus, its most substantiated role beyond depression is in addressing sleep-related issues.
