Claimed effect of echinacea
Echinacea is thought to stimulate the immune system. When taken at the onset of a cold, it is said to shorten the duration of cold symptoms. This claimed effect has not been proven by research. Topical use may promote wound healing.
Adverse Effects of Echinacea
Most adverse effects are mild and transient; they include dizziness, fatigue, headache, and gastrointestinal symptoms. No other adverse effects are known. Theoretical contraindications for echinacea include autoimmune disorders, multiple sclerosis, AIDS, tuberculosis, and organ transplantation because it may stimulate T cells. Echinacea inhibits some cytochrome P450 enzymes and stimulates others; it may therefore potentially interact with drugs metabolized by the same enzymes (eg, anabolic steroids, azole antifungals, methotrexate). Allergic reactions are possible in patients with pollen allergy.
