Native American peoples used echinacea root and leaves for wounds, snake bites, stings and infections. In 19th- and 20th-century Western herbal practice it became a leading remedy for colds, flu and upper respiratory infections, and for minor skin complaints.
NCCIH calls the evidence unclear and weak overall. A 2014 Cochrane review of 24 trials (4,631 participants) found echinacea had not been clearly shown to help once a cold was underway, though a weak benefit from some preparations remains possible; a 2019 meta-analysis found a possible small effect on catching colds. Results vary by species and preparation, and the most studied single product is a fresh-pressed E. purpurea extract.
Safe: 2,500-6,000 mg/day dried herb, or 900-4,500 mg/day dried root (Egyptian Herbal Monograph; use for not more than 10 days at a time).
