People with certain allergies should not take echinacea. This is particularly true for people who are allergic to plants in the Asteraceae or Compositae family. These are large families that contain a variety of plant types, including ragweed, chrysanthemums, marigolds and daisies.
People with asthma or atopy (a genetic tendency to experience allergic reactions) are also more likely to experience adverse reactions to echinacea.
So me experts have recommended that people with a compromised immune system avoid taking echinacea. Such conditions include HIV/AIDS, some types of cancer, multiple sclerosis, tuberculosis and rheumatologic diseases (e.g., lupus, rheumatoid arthritis). However, there is no specific scientific research study that supports such concerns. |
