Because St. John s Wort can be purchased without a prescription, people may use it to treat self-diagnosed symptoms of depression independently, and they may not seek necessary medical advice. For some individuals, St. John s Wort can have other very unpleasant side effects. The combination of St. John s Wort and ragweed exposure can cause a very serious allergic reaction in individuals who have allergies, especially asthma. The herb also can cause skin burns in light-skinned people because is contains hypersen, a photosensitizing substance that reacts with light. Even though a prescription is not required, it is wise to talk with your physician before taking St. John s Wort regularly.
Recommendations Avoid the pharmacologically active herbal teas.
Drink any herbal teas only in moderation. Limit intake of any herbal preparation that combines several active ingredients. Always check the label. Even vitamins and simple echinacea may contain herbs that should not be used by breastfeeding mothers, such as ginkgo or ginseng. Use only reliable brands that have ingredients and concentrations clearly marked on the label, as well as the expiration date and the name of the manufacturer and distributor.
