Causes, Symptoms, and Risk Factors of the Common Cold and Flu
The common cold and flu are caused by a variety of viruses, with the most common culprit being the rhinovirus for colds and the influenza virus for the flu. Both infections can cause a range of symptoms, including fever, sore throat, cough, nasal congestion, and muscle aches. While most people recover from the cold and flu without complications, certain groups such as young children, the elderly, and individuals with weakened immune systems may be at a higher risk for severe symptoms or complications.
Echinacea's Immune-Boosting Potential
- Echinacea, a group of flowering plants native to North America, has been used for centuries by indigenous people to treat a wide range of ailments. Recent scientific research has provided support for the traditional use of Echinacea in enhancing the immune system's ability to fight off infections.
- A study published in the journal "Phytotherapy Research" in 2012 found that Echinacea extracts reduced the duration and severity of cold symptoms in participants. In this double-blind, randomized, placebo-controlled study, participants who took Echinacea extracts experienced a shorter duration of cold symptoms by 1.4 days, compared to those who received a placebo.
- Furthermore, a review of 14 studies conducted by the Cochrane Database of Systematic Reviews in 2014 concluded that Echinacea products might be effective in preventing colds, reducing the risk by 10 to 20 percent. Another study published in "Virology Journal" in 2009 found that Echinacea purpurea extract had antiviral effects against the influenza virus, suggesting that it could potentially help in the prevention and treatment of the flu as well.
