St Johns Wort is not a good substitute for clinical depression, and should not be used as such. It has a positive effect in people with mild depression and may be useful in halping them to feel better, but trials have yet to prove it has any long term benefits for patients with long term depression
Research into the use of St John's Wort to treat depression
St John's Wort and depression
St John's Wort was tested in a double-blind study of 105 patients suffering from mild-moderate depression. The patients were male and female , 20 to 64 years of age, and diagnosed as having neurotic depression or temporary depressive mood. They were then divided into two groups and monitored over a period of four weeks. One group were given 300mg of St John's Wort extract, three times daily, and the other group were given a placebo. All of the patients were given psychiatric evaluations before the start of the study , and after two and four weeks of treatment.
The results revealed that, after the four weeks, 67% of the Hypericum group had responded positively to the treatment without any adverse side effects whereas only 28% of the placebo group showed any signs of improvement.
The authors of the study state clearly that the study was deliberately confined to patients affected by mild forms of depression because, for those patients, the possible risks of traditional antidepressants often outweighed any expected benefits. Indeed many patients within that category were known to refuse medications because of the possible side effects. Therefore, whilst there was no evidence to suggest that Hypericum would be of any benefit to patients suffering from the more serious forms of depression, in relation to the lesser but more common forms of depression, the researchers recommend: 'Hypericum should be used as a remedy of choice'.

St John's Wort (Hypericum) beats depression
The number of visits to alternative medicine practitioners in this country is estimated at 425 million, which is more than the number of visits to allopathic primary care physicians in 1990. Patients' use of St. John's Wort (SJW) has followed this sweeping trend. The purpose of our study was to examine the reasons people choose to self-medicate with SJW instead of seeking care from a conventional health care provider.
The researchers used open-ended interviews with key questions to elicit information. Twenty-two current users of SJW (21 women; 20 white; mean age = 45 years) in a Southern city participated. All interviews were transcribed, and descriptive participant quotes were extracted by a research assistant. Quotes were reviewed for each key question for similarities and contextual themes.
Four dominant decision-making themes were consistently noted. These were: (1) Personal Health Care Values: the patients had a history of alternative medicine use and a belief in the need for personal control of health; (2) Mood: all SJW users reported a depressed mood and occasionally irritability, cognitive difficulties, social isolation, and hormonal mood changes; (3) Perceptions of Seriousness of Disease and Risks of Treatment: SJW users reported the self-diagnosis of "minor" depression, high risks of prescription drugs, and a perception of safety with herbal remedies; and (4) Accessibility Issues: subjects had barriers to and lack of knowledge of traditional health care providers and awareness of the ease of use and popularity of SJW. Also of note was the fact that some SJW users did not inform their primary care providers that they were taking the herb (6 of 22). Users reported moderate effectiveness and few side effects of SJW.
SJW users report depression, ease of access to alternative medicines, and a history of exposure to and belief in the safety of herbal remedies. Users saw little benefit to providing information about SJW to primary care physicians.

Hypericum & depression - a review of the research
A comprehensive evaluation of the benefits and adverse effects of newer pharmacotherapies and herbal treatments for depressive disorders in adults and children was undertaken..
Literature published between 1980 to January 1998 was identified from a specialized registry of controlled trials, meta-analyses, and experts. The registry contained trials addressing depression that had been identified from multiple electronic bibliographic databases, hand searches of journals, and pharmaceutical companies. The search, which yielded 1,277 records, combined terms "depression," "depressive disorder," or "dysthymic disorder" with a list of 32 specific "newer" antidepressant and herbal treatments.
Randomized controlled trials were reviewed if they (1) were at least 6 weeks in duration; (2) compared a "newer" antidepressant with another antidepressant (newer or older), placebo, or psychosocial intervention; (3) involved participants with depressive disorders; and (4) had a clinical outcome. 315 trials that met these criteria.
Data was independently abstracted from each trial by two persons. The researchers looked at the response rate, total discontinuation rates (dropouts), and discontinuation rates due to adverse events. Response rates were defined as a 50 percent or greater improvement in symptoms as assessed by a depression symptoms rating scale or a rating of much or very much improved as assessed by a global assessment method.
There were 264 trials that evaluated antidepressants in patients (adults and children) with major depression. Of these, there were 14 trials evaluating hypericum (St. John's wort), and a review of these studies revealed that the herb was more effective than placebo in treating mild to moderately severe depressive disorders (risk ratio 1.9, 95% CI 1.2 to 2.8). However, the question as to whether hypericum (St. John's wort) is as effective as standard antidepressant agents given in adequate doses was not established.

St. John's Wort a plant with yellow flowers.
Common Names--St. John's wort, hypericum, Klamath weed, goat weed
Latin Name--Hypericum perforatum
What It Is Used For
St. John's wort has been used for centuries to treat mental disorders and nerve pain.
In ancient times, herbalists wrote about its use as a sedative and a treatment for malaria, as well as a balm for wounds, burns, and insect bites.
Today, St. John's wort is used by some for depression, anxiety, and/or sleep disorders.
How It Is Used
The flowering tops of St. John's wort are used to prepare teas and tablets containing concentrated extracts.
What the Science Says
There is some scientific evidence that St. John's wort is useful for treating mild to moderate depression. However, two large studies, one sponsored by NCCAM, showed that the herb was no more effective than placebo in treating major depression of moderate severity.
NCCAM is studying the use of St. John's wort in a wider spectrum of mood disorders, including minor depression.
Side Effects and Cautions
St. John's wort may cause increased sensitivity to sunlight. Other side effects can include anxiety, dry mouth, dizziness, gastrointestinal symptoms, fatigue, headache, or sexual dysfunction.
Research shows that St. John's wort interacts with some drugs. The herb affects the way the body processes or breaks down many drugs; in some cases, it may speed or slow a drug's breakdown. Drugs that can be affected include:
Indinavir and possibly other drugs used to control HIV infection
Irinotecan and possibly other drugs used to treat cancer
Cyclosporine, which prevents the body from rejecting transplanted organs
Digoxin, which strengthens heart muscle contractions
Warfarin and related anticoagulants
Birth control pills
Antidepressants
When combined with certain antidepressants, St. John's wort may increase side effects such as nausea, anxiety, headache, and confusion.
St. John's wort is not a proven therapy for depression. If depression is not adequately treated, it can become severe. Anyone who may have depression should see a health care provider. There are effective proven therapies available.
It is important to inform your health care providers about any herb or dietary supplement you are using, including St. John's wort. This helps to ensure safe and coordinated care.
