Laboratory research suggests that echinacea can stimulate the body's immune system, but there is no evidence that this occurs in people.
Echinacea also seems to contain some chemicals that can attack yeast and other kinds of fungi directly.
Some side effects have been reported such as fever, nausea, vomiting, unpleasant taste, stomach pain, diarrhea, sore throat, dry mouth, headache, numbness of the tongue, dizziness, insomnia, disorientation, and joint and muscle aches. In rare cases, echinacea has been reported to cause inflammation of the liver.
Applying echinacea to the skin can cause redness, itchiness, or a rash.
Echinacea is most likely to cause allergic reactions in children and adults who are allergic to ragweed, mums, marigolds, or daisies. If you have allergies, be sure to check with your healthcare provider before taking echinacea.
Special Precautions & Warnings:Children: Echinacea is POSSIBLY SAFE when taken by mouth in the short-term. It seems to be safe in most children ages 2-11 years. However, about 7% of these children may experience a rash that could be due to an allergic reaction. There is some concern that allergic reactions to echinacea could be more severe in some children. For this reason, some regulatory organizations have recommended against giving echinacea to children under 12 years of age.
Pregnancy: Echinacea is POSSIBLY SAFE when taken by mouth in the short-term. There is some evidence that echinacea might be safe when taken during the first trimester of pregnancy without harming the fetus. But until this is confirmed by additional research, it is best to stay on the safe side and avoid use.
Breast feeding: There is not enough reliable information about the safety of taking echinacea if you are breast feeding. Stay on the safe side and avoid use.
An inherited tendency toward allergies (atopy): People with this condition are more likely to develop an allergic reaction to echinacea. It's best to avoid exposure to echinacea if you have this condition.
"Auto-immune disorders" such as such as multiple sclerosis (MS), lupus (systemic lupus erythematosus, SLE), rheumatoid arthritis (RA), a skin disorder called pemphigus vulgaris, or others: Echinacea might have an effect on the immune system that could make these conditions worse. Don't take echinacea if you have an auto-immune disorder.
