St. John's wort is an extract from the Hypericum perforatum plant. The extract has traditionally been given to patients suffering from a variety of conditions. One possible application of St. John's wort is in the treatment of anxiety. Understanding the benefits and limitations of St. John's wort can help you decide if it is right for you. As always, consult a physician prior to taking any medical or dietary supplement.
Uses of St. John's Wort
St. John's wort has been used to treat numerous medical conditions. Most commonly, it is used in patients suffering from depression, MedlinePlus reports. Typically, the supplement is most effective in treating mild to moderate depression. St. John's wort is also purported to be effective in treating heart palpitations, mood changes, symptoms of menopause, and psychological disorders such as attention deficit-hyperactivity disorder or seasonal affective disorder.
St. John's Wort and Anxiety
Anxiety is the intense feeling of nervousness or unease about the future or present events. Often anxiety is a symptom of an underlying condition such as bipolar disorder, depression or paranoia. According to Drugs.com, St. John's wort has been used to alleviate anxiety. When anxiety is associated with mild depression, St. John's work can be very effective. However, an article in the August 15, 2007, edition of "American Family Physician" claims that St. John's wort may not be truly effective in treating anxiety. The article cites the lack of clear clinical evidence of the extract's ability to treat patients with anxiety. The study recommends that further trials should be performed in order to evaluate the effectiveness of the drug.
How Does St. John's Wort Work?
The chemicals found in the St. John's wort extract provide the medical benefit of the supplement. It was once thought that the chemical hypericin was the chief functional ingredient, MedlinePlus explains. However, recent information states that hyperforin is the more active compound. Both these chemicals act on neurotransmitters within your body's nervous system. By modulating the functions of these neurotransmitters, St. John's wort is able to regulate your mood.
Side Effects
St. John's wort, like most compounds used for medical treatment, can have adverse side effects. Though rare, you may have an allergic reaction to the ingredients of St. John's wort, Drugs.com warns. If you experience any swelling of your tongue or face or have any difficulty breathing after taking the supplement, seek immediate medical attention. Other less serious side effects include a rash, gastrointestinal distress and constipation. If you use St. John's wort on your skin, you may develop a rash and an increased sensitivity to sunlight.
