Sinus infections are a common condition in the United States, affecting more than 30 million Americans annually, according to the University of Maryland's Medical Clinic. Traditional medications are available over the counter to treat sinus infections, but for those who want to try a natural approach, echinacea is a good choice. Echinacea is known for its anti-inflammatory and ability to improve the immune system's performance, according to Drugs.com. Talk with your doctor before using any supplement to treat a medical condition.
Background
The sinuses are empty cavities in the head that are lined with mucus membranes. The sinuses help to filter the air before it enters the lungs to catch any unwanted airborne particles. The nasal tissue is sensitive to various factors that can trigger inflammation and infection. Some of the most common triggers include allergies, the common cold and environmental factors, according to MayoClinic.com. When the sinuses become irritated, they swell and lead to infection.
Symptoms
Symptoms of sinusitis are nasal congestion, sinus pain, a runny nose, low-grade fever, minor body chills, post-nasal drip, coughing and fatigue, according to the University of Maryland's Medical Clinic. The infection in the sinus cavity causes the tissue to swell, leading to excess pressure placed on other aspects of the head. The swollen sinuses cause pressure that can be felt in the eyes, ears, forehead, upper-teeth and behind the cheeks. The face may become sensitive to touch and a dull, throbbing pain may be present in the center of the head.
Echinacea Use
Echinacea can be used to treat a sinus infection because of its strong antibacterial properties, according to Sinus Infection Help. Echinacea has also been known to help support the immune system, which will help kill the bacteria or virus faster. Drugs.com warns that Echinacea has not been evaluated by the FDA and should only be used under a doctor's supervision. Talk to your doctor about the appropriate dose for your condition and medical history.
Side Effects
The most common side effects of using echinacea are vomiting, nausea and a fever, according to Drugs.com. As with any herb, you may experience an allergic reaction to echinacea. If you develop common allergy related symptoms, call your doctor. These symptoms include hives, skin rashes, shortness of breath, wheezing, swelling in the lips, tongue or face and nasal congestion. A severe allergic reaction can be life-threatening and will require emergency medical attention.
Consideration
Your doctor may recommend using echinacea alongside other common drugs for a sinus infection. Other over-the-counter drugs may include pain relievers, antihistamines and decongestants. Your doctor may prescribe an antibiotic if your condition does not improve.
