St. John's Wort

Hypericum perforatum


Used for:

Seasonal affective disorder (SAD) also know as the "winter blues," mild to moderate depression, nervousness, insomnia, anorexia, skin irritation, including herpes simplex.



Available in:

Tablets, capsules, tinctures, fluid extract, powdered extract, oil



Heb / drug interactions:

St. John's wort probably acts in the nervous system as an SSRI (selective serotonin reuptake inhibitor), but unlike other SSRIs such as Prozac and Zoloft, St. John's wort affects additional neurotransmitters as well. Therefore, when taken with SSRIs or other mood-altering drugs, St. John's wort may cause causing serotonin syndrome (overload). St. John's wort should not simply be added to an existing pharmaceutical regimen, especially if taking other anti-depressants. Women using birth control pills. those taking Inadivir for HIV or those taking cyclosporine should avoid St. John's wort. In addition, patients being treated with anti-arrythmics such as Digoxin (Lanoxin) or taking blood-thinning medications such as Coumadin should not use St. John's wort.



Other safety concerns:

High intake may cause photosensitivity; take precautions with sun exposure. Takes two months for St. Johns wort's antidepressant effect to be noticeable. Acts as a blood thinner. St. John's wort side effects: May interfere with metabolism of certain medications.



When Buying:

Look for standardized products. For topical use on irritated skin, apply the oil directly several times a day.



Dosage

300 milligrams three times a day.



Child Dosage:

Half the adult dosage. Not to be combined with other mood drugs or antidepressants. Topical applications same as adult.
