Depression is a feeling of intense sadness that seems out of proportion to life events, is coupled with physical symptoms (changes in sleep or appetite, trouble concentrating, tiredness, and lowered sex drive), or lasts more than two weeks.Although prescription drugs and counseling are the most effective treatments for depression, many people report feeling better after using certain herbal products and dietary supplements. St. John's wort is an herb that can help mild to moderate depression. Research shows it may be as effective and better tolerated than the tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs), which are only available with a prescription. St. John's wort is not effective for severe depression. SAM-e (s-adenosylmethionine) is a dietary supplement advertised to promote "emotional well being." It shows some promise when people use it for up to four weeks as a treatment for depression. But we need more studies to find out if it's useful and safe for longer periods. Alternative therapies aren't right for everyone. They can cause side effects and may interact with many other drugs including antidepressant drugs. Talk with your doctor before trying alternative therapies for depression. Sources: Salmaggi, P.
