Echinacea is a plant that is widely used to treat the common cold. There are nine known species that are all native to North America. The most common species used in dietary supplements are Echinacea purpurea or Echinacea angustifolia. Echinacea available for purchase can vary greatly due to different types, preparation, and parts of the plant being used.
Many studies have investigated effects of Echinacea, with varying outcomes and no clear understanding that Echinachea helps to prevent a cold. However, studies have shown that some preparations of Echinacea purpurea can help to shorten the duration & severity of the common cold. This may be effective in adults, but not in children.
It is recommended that Echinacea preparations shouldn’t be consumed for longer than 8 weeks. At this stage, no harmful side effects are known, but the evidence for long-term use is still very limited.
