Now that cold and flu season is near, you’ve likely begun hearing a lot about popular immune system helpers like echinacea, goldenseal, zinc and vitamin C – and for good reason. Years of solid research show that these natural remedies can help prevent a viral infection taking hold, and ease symptoms when one does slip by. However, a few lesser known remedies are now joining the ranks of powerful cold and flu fighters due to impressive research in the area of immune system health.
People who forgo a flu shot have many alternatives.
Quercitin
A new study reveals that quercetin, a substance found in fruits and vegetables, can lower the chances of contracting the flu, even for those under physical or psychological stress."Quercetin was used because of its documented widespread health benefits,which include antiviral activity, abundance in the diet and reported lack offside effects when used as a dietary supplement or food additive," said J.Mark Davis of the University of South Carolina.
Using an animal model, he and colleagues examined groups of mice exposed to a common flu virus. The researchers found that mice that exercised to fatigue were more likely to develop the flu (and develop it sooner) than mice that did not exercise, but that those who exercised an took quercitin had nearly the same rate of flu as those that did not exercise. In other words, quercetin canceled out the negative effect of stressful exercise. Quercetin also had protective effects for the mice that did not exercise. A recent human study found similar results.
Elderberry
New research on elderberry backs up years of use in folk medicine to treat influenza, colds and sinusitis. It has been reported to have antiviral activity against influenza and herpes simplex, the virus that cause scold sores.
Researchers investigated the safety and effectiveness of oral elderberry syrup for treating influenza A and B infections in 60 adult patients suffering from influenza-like symptoms for 48 hours or less. Patients received 15 ml of elderberry or placebo syrup four times a day for 5 days, and recorded their symptoms. Researchers found that symptoms were relieved on average 4 days earlier, and use of medication to relieve symptoms was significantly less in those receiving elderberry extract compared with placebo.
"Elderberry extract seems to offer an efficient, safe and cost-effective treatment for influenza," the researchers conclude.
Pelargonium sidoides
German scientists at the University Hospital Freiburg report that a preparation of the roots of Pelargonium sidoides (EPs 7630, or Umcka) can significantly improve symptoms of acute bronchitis. Acute bronchitis, commonly associated with cough, is predominantly caused by viral infections.
The researchers tested the herbal preparation on 217adult outpatients with acute bronchitis. Compared with placebo, a marked improvement was seen for the herb group for all disease symptoms (cough,sputum, rales, dyspnoe, pain on coughing, hoarseness, headache, fatigue, fever and limb pain). Patients in the herb group were sooner able to return to work and spent less time confined to bed. The herbal preparation was well tolerated and no serious adverse events were observed.
