(See also nutritional supplements Overview.) Echinacea is a North American wild plant (coneflower) with a number of biologically active ingredients. Echinacea claims to act immune stimulant and is reputed to shorten the duration of symptoms if one takes it right at the beginning of a cold. Carefully conducted, but well-controlled studies have failed to demonstrate this effect. So wounds heal more quickly, Echinacea preparations are applied locally. Evidence studies on the role of Echinacea in the prevention and / or treatment of the common cold are inconsistent. The biggest factor that contributes to inconsistency, is the variability of plant preparations (including various plant parts and types) and the final composition of the supplement. According to a Cochrane review from 2006, the aerial parts of the plant might be effective for the early treatment of colds; also could other preparations of echinacea, a role in the prevention of colds have (1). However, it needed more meticulous randomized controlled trials. Most side effects occur only temporarily ease side effects such as dizziness, fatigue, headache and gastrointestinal symptoms. Other side effects are not known. Since it can stimulate T-cells, Echinacea is purely theoretical for patients with autoimmune diseases, multiple sclerosis, AIDS, tuberculosis and contraindicated after organ transplantation. Some of cytochrome P-450 enzymes are inhibited by Echinacea and other stimulated; therefore it could drug interactions (u. a. anabolic steroids, azoles / antifungal agents, methotrexate) are metabolized by the same enzymes. Allergic reactions are possible in patients with allergies to ragweed, chrysanthemums, marigolds, daisies or related allergens. Some drug interactions cytochrome P-450 enzymes are inhibited by Echinacea and other stimulated; therefore it could drug interactions (u. a. anabolic steroids, azoles / antifungal agents, methotrexate, etoposide, and other chemotherapeutic drugs) are metabolized by the same enzymes.
