Echinacea
Echinacea purpurea
Immunomodulatory/immunostimulant in traditional Western herbal practice, most commonly used at the beginning of respiratory infections. NCCIH reports evidence suggesting echinacea may modestly improve cold symptoms, but the evidence quality is low to moderate and effects vary by species and preparation. Root is the classic concentrated medicine; flowers and leaves may also be used.
Immune stimulant — Traditionally stimulates aspects of immune response
Lymphatic — Traditionally supports lymph flow and lymphatic function
