Echinacea is a well-researched and widely used herbal remedy for immune support, respiratory health, and wound healing. Its antiviral, antimicrobial, and anti-inflammatory properties make it effective for managing colds, flu, and skin conditions. While generally safe, it should be used cautiously in individuals with autoimmune conditions or plant allergies.
