Did you know echinacea, or purple coneflower, is one of the most popular herbs in the world? Many use it for pain, migraines, and general infections or viruses. High in antioxidants, echinacea can help the body when dealing with oxidative stress. This supplement ingredient can promote a healthy immune system as studies have shown its positive effect on the duration of common colds. No, your product label cannot claim that echinacea supplements are intended to treat or cure diseases, but you can absolutely advertise its potential to help your customers in their health improvement efforts.
