U.S. NCCAM National Institutes of Health -
Overview
The name St. John's wort apparently refers to John the Baptist, as the plant blooms around the time of the feast of St. John the
Baptist in late June. The flowering tops of St. John's wort are used to prepare teas and tablets containing concentrated extracts.
Possible Benefits
Possible benefits [include] -
- St. John's wort has been used for centuries to treat mental disorders and nerve pain.
- St. John's wort has also been used 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.
As a Treatment for Depression
Scientific evidence regarding the effectiveness of St. John's wort for depression is inconsistent. An analysis of the results of 37
clinical trials concluded that St. John's wort may have only minimal beneficial effects on major depression. However, the analysis
also found that St. John's wort may benefit people with minor depression; these benefits may be similar to those from standard
antidepressants. Overall, St. John's wort appeared to produce fewer side effects than some standard antidepressants (emphasis added).
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:
- Antidepressants
- Birth control pills
- Cyclosporine, which prevents the body from rejecting transplanted organs
- Digoxin, which strengthens heart muscle contractions
- Indinavir and possibly other drugs used to control HIV infection
- Irinotecan and possibly other drugs used to treat cancer
- Warfarin and related anticoagulants
- When combined with certain antidepressants, St. John's wort may increase side effects such as nausea, anxiety, headache, and confusion.
"Serotonin syndrome can occur when you take certain combinations of prescription medications [including some medications for depression or migraines] that
affect serotonin levels in your body.
... Serotonin syndrome can also occur if you take SSRIs with other drugs or supplements that affect serotonin levels, such as St. John's wort.
If not treated quickly, serotonin syndrome can become life-threatening."
- Mayo Clinic
Manufacturers' Info from the Bottle Labels
From the Nature's Way Capsules label -
St. John’s Wort (Hypericum perforatum) promotes a positive mood. It is native to Europe, North Africa, and western Asia.
From the Nature's Way Perika® Tablets label -
Hyperforin: The proven "mood enhancing" active [ingredient] in St. John’s Wort. New clinical research reveals hyperforin-rich Perika® to be
more effective in promoting a positive mood than low hyperforin St. John’s Wort. In fact, 15% more users reported "much or very much
improved" emotional status by using Perika® in comparison to other St. John’s Wort. Perika’s HyperiSure® Difference: Hyperforin is
rather unstable and can lose potency over time. However, using the patented HyperiSure® System technology, Perika® contains a
guaranteed level of hyperforin to deliver clinically proven effectiveness.
