According to scientists echinacea can be used to prevent the common cold and it has the ability to lower the risk of contracting the disease by more than fifty percent, the time period of cold by 1 and ½ day.
The result of the study is published in ‘The Lancet Infectious Diseases’. The study results are contradictory with other studies which that it has no benefits.
Few of the experts assured that echinacea a group of 9 associated plant species belonging to North America, work by energizing the person’s immunity.
The lead researcher of the study is — Dr Craig Coleman from the University of Connecticut School of Pharmacy. The study results are the combination of the results of 14 studies done on echinacea’s anti-cold functions.
When echinacea was consumed along with vitamin C. The combination then lowered cold occurrence by 86 percent. When this herbal remedy is used only than it lowered the cold by 65 percent.
And when people were vaccinated with the rhinovirus (which is considered to be the most common of all the viruses) that can cause cold, echinacea lowered the cold occurrence by 35 percent.
The researcher discovered that nearly 800 products that contain the echinacea are already present in the market. Different parts of a plant like its root, flower, and stem were used to make these products.
Professor Ron Cutler, of the University of East London, said in a prepared statement:
The true benefits, and more importantly, how the agents work remains unclear and further better-controlled actual clinical trials still have to be carried out.
The rhinoviruses cause nearly half of all the common colds among kids and adults. School goers normally get 7 to 10 colds in a year, and adults up to 2 to 5. Common colds and flu are transmitted through hand to hand contact and generally by the contact of floors, places etc touched by the entire passerby.
Echinacea may lower the time period of sickness and reduces the seriousness of coughing, headache, and also the nasal blocking.
