Echinacea for colds — the evidence
Cochrane looked at the trials: echinacea preparations do not shorten colds by a meaningful margin. The studies are messy because "echinacea" is not one product — species, part of the plant and extraction all differ — but the honest summary is that no preparation has shown a consistent effect.
Ce que disent les preuves
Verdict: No clear evidence. Cochrane looked at the trials: echinacea preparations do not shorten colds by a meaningful margin. The studies are messy because "echinacea" is not one product — species, part of the plant and extraction all differ — but the honest summary is that no preparation has shown a consistent effect.
Quoi faire vraiment
Not worth the money for a cold. If you like the ritual of a warm herbal drink, the drink is fine — just do not expect it to move the illness.
