In the past few years, much interest has risen in the use of herbs in the treatment of both depression and anxiety. St. John's wort (Hypericum perforatum), an herb used extensively in the treatment of mild to moderate depression in Europe, has recently aroused interest in the United States. St. John's wort, an attractive bushy, low-growing plant covered with yellow flowers in summer, has been used for centuries in many folk and herbal remedies. Today in Germany, Hypericum is used in the treatment of depression more than any other antidepressant. However, the scientific studies that have been conducted on its use have been short-term and have used several different doses.

Because of the widespread interest in St. John's wort, the National Institutes of Health (NIH) conducted a 3-year study, sponsored by three NIH components—the National Institute of Mental Health, the National Center for Complementary and Alternative Medicine, and the Office of Dietary Supplements. The study was designed to include 336 patients with major depression of moderate severity, randomly assigned to an 8-week trial with one-third of patients receiving a uniform dose of St. John's wort, another third sertraline, a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for depression, and the final third a placebo (a pill that looks exactly like the SSRI and the St. John's wort, but has no active ingredients). The study participants who responded positively were followed for an additional 18 weeks. At the end of the first phase of the study, participants were measured on two scales, one for depression and one for overall functioning. There was no significant difference in rate of response for depression, but the scale for overall functioning was better for the antidepressant than for either St. John's wort or placebo. While this study did not support the use of St. John's wort in the treatment of major depression, ongoing NIH-supported research is examining a possible role for St. John's wort in the treatment of milder forms of depression.

The Food and Drug Administration issued a Public Health Advisory on February 10, 2000. It stated that St. John's wort, appears to affect an important metabolic pathway that is used by many drugs prescribed to treat conditions such as AIDS, heart disease, depression, seizures, certain cancers, and rejection of transplants. Therefore, health care providers should alert their patients about these potential drug interactions.

Some other herbal supplements frequently used that have not been evaluated in large-scale clinical trials are ephedra, gingko biloba, echinacea, and ginseng. Any herbal supplement should be taken only after consultation with the doctor or other health care provider.

PSYCHOTHERAPIES

Many forms of psychotherapy, including some short-term (10-20 week) therapies, can help depressed individuals. "Talking" therapies help patients gain insight into and resolve their problems through verbal exchange with the therapist, sometimes combined with "homework" assignments between sessions. "Behavioral" therapists help patients learn how to obtain more satisfaction and rewards through their own actions and how to unlearn the behavioral patterns that contribute to or result from their depression.

Two of the short-term psychotherapies that research has shown helpful for some forms of depression are interpersonal and cognitive/behavioral therapies. Interpersonal therapists focus on the patient's disturbed personal relationships that both cause and exacerbate (or increase) the depression. Cognitive/behavioral therapists help patients change the negative styles of thinking and behaving often associated with depression.

Psychodynamic therapies, which are sometimes used to treat depressed persons, focus on resolving the patient's conflicted feelings. These therapies are often reserved until the depressive symptoms are significantly improved. In general, severe depressive illnesses, particularly those that are recurrent, will require medication (or ECT under special conditions) along with, or preceding, psychotherapy for the best outcome.

HOW TO HELP YOURSELF IF YOU ARE DEPRESSED

Depressive disorders make one feel exhausted, worthless, helpless, and hopeless. Such negative thoughts and feelings make some people feel like giving up. It is important to realize that these negative views are part of the depression and typically do not accurately reflect the actual circumstances. Negative thinking fades as treatment begins to take effect. In the meantime:

• Set realistic goals in light of the depression and assume a reasonable amount of responsibility.
• Break large tasks into small ones, set some priorities, and do what you can as you can.
• Try to be with other people and to confide in someone; it is usually better than being alone and secretive.
• Participate in activities that may make you feel better.
• Mild exercise, going to a movie, a ballgame, or participating in religious, social, or other activities may help.
• Expect your mood to improve gradually, not immediately. Feeling better takes time.
• It is advisable to postpone important decisions until the depression has lifted. Before deciding to make a significant transition—change jobs, get married or divorced—discuss it with others who know you well and have a more objective view of your situation.
• People rarely "snap out of" a depression. But they can feel a little better day-by-day.
• Remember, positive thinking will replace the negative thinking that is part of the depression and will disappear as your depression responds to treatment.
• Let your family and friends help you.

How Family and Friends Can Help the Depressed Person

The most important thing anyone can do for the depressed person is to help him or her get an appropriate diagnosis and treatment. This may involve encouraging the individual to stay with treatment until symptoms begin to abate (several weeks), or to seek different treatment if no improvement occurs. On occasion, it may require making an appointment and accompanying the depressed person to the doctor. It may also mean monitoring whether the depressed person is taking medication. The depressed person should be encouraged to obey the doctor's orders about the use of alcoholic products while on medication. The second most important thing is to offer emotional support. This involves understanding, patience, affection, and encouragement. Engage the depressed person in conversation and listen carefully. Do not disparage feelings expressed, but point out realities and offer hope. Do not ignore remarks about suicide. Report them to the depressed person's therapist. Invite the depressed person for walks, outings, to the movies, and other activities. Be gently insistent if your invitation is refused. Encourage participation in some activities that once gave pleasure, such as hobbies, sports, religious or cultural activities, but do not push the depressed person to undertake too much too soon. The depressed person needs diversion and company, but too many demands can increase feelings of failure.

Do not accuse the depressed person of faking illness or of laziness, or expect him or her "to snap out of it." Eventually, with treatment, most people do get better. Keep that in mind, and keep reassuring the depressed person that, with time and help, he or she will feel better.

WHERE TO GET HELP

If unsure where to go for help, check the Yellow Pages under "mental health," "health," "social services," "suicide prevention," "crisis intervention services," "hotlines," "hospitals," or "physicians" for phone numbers and addresses. In times of crisis, the emergency room doctor at a hospital may be able to provide temporary help for an emotional problem, and will be able to tell you where and how to get further help.

Listed below are the types of people and places that will make a referral to, or provide, diagnostic and treatment services.

• Family doctors
• Mental health specialists, such as psychiatrists, psychologists, social workers, or mental health counselors
• Health maintenance organizations
• Community mental health centers
• Hospital psychiatry departments and outpatient clinics
• University- or medical school-affiliated programs
• State hospital outpatient clinics
• Family service, social agencies, or clergy
