Echinacea: A Wise Choice for Upper Respiratory Infections

If you haven't tried echinacea to help you through a cold or flu bug, you might want to consider it. This herb has been used for hundreds of years—in America, native Americans used it and shared their knowledge of its medicinal value with early European settlers. Recent scientific studies are supporting its ability to reduce both the severity and duration of colds, flus, and sore throats when it's taken at the onset of symptoms. It appears to stimulate the immune system's response to infections; however, it has not been shown effective for preventing upper respiratory infections.

Echinacea comes from the dried root and leaves of the Echinacea purpurea plant and its related species. There are many different forms of echinacea available, including teas, tinctures, and capsules. At the first sign of a cold, experts recommend taking small, frequent doses of 1 to 2 droppers of tincture every 2 to 3 hours or 200 mg in capsule form three times a day. It is also recommended that you buy from a reputable manufacturer that uses a standardized extract.

As symptoms improve, stop taking echinacea. The safety of long-term echinacea use is unknown, and experts don't recommend using it for more than 8 weeks in a row. Side effects may include gastrointestinal distress, headache, and hypersensitivity. It is not recommended for people with an autoimmune disease such as multiple sclerosis or HIV/AIDs. It is not known whether or not echinacea can be used safely during pregnancy, so it's possibly wise to avoid using it until after the birth of your child.

Remember that often colds and flu are your body's way of saying it's time to slow down. Don't forget the tried-and-true remedies: Drink a lot of fluids and get plenty of rest.
