How Echinacea Helps with Cold & Flu
Echinacea stimulates white blood cell production and activates the innate immune system. It works best as prevention and early intervention rather than treating established infections.
🔬 What the Research Says
A 2014 Cochrane review of 24 trials found echinacea may reduce the risk of developing a cold by 10-20%, though results varied by preparation type.
