Question

Quizplus · Accepted Answer

Echinacea is known for its immune-boosting properties and is often taken to prevent or treat the common cold and flu. Given Rich's close quarters with 30 fraternity brothers, taking Echinacea may help strengthen his immune system and prevent him from getting sick. Flaxseed, ginkgo biloba, and ginseng do not have specific immune-boosting properties and would not be as effective in preventing illness.
