  • What do Echinacea supplements do? Echinacea supplements may modestly help prevent colds when taken during cold season and/or reduce the severity of a cold if taken at the first onset of symptoms (See What It Does).
  • What is Echinacea? Phenolic compounds in Echinacea may be responsible for some of the herb's effects (See What It Is).
  • What did CL's tests of Echinacea find? found that two products did not contain the expected minimum amounts of total phenolic compounds (TPCs), one product exceeded a limit for lead contamination, and another product failed to properly label its Echinacea. (See What CL Found).
  • Best Echinacea supplements? Among 10 products Approved for Quality by, three were chosen as Top Picks.
  • Which form of Echinacea is best? Echinacea comes in various forms and concentrations, but most positive clinical studies used products extracted from aerial parts (leaves, flowers, stems) of E. purpurea, often dried into extract powders (900 mg per day taken in 3 divided doses). (See ConsumerTips™).
  • Echinacea safety and side effects: Echinacea appears to be relatively safe for short-term use (up to 12 weeks) and side-effects tend to be mild (GI symptoms, increases urination). However, be aware that some people may be allergic, and rarely, liver damage has been reported (See Concerns and Cautions).
