Burdock root contains approximately 50% inulin,20 a fiber widely distributed in fruits, vegetables and plants. Inulin is classified as a food ingredient (not as an additive) and is considered to be safe to eat.21 In fact, inulin is a significant part of the daily diet of most of the world's population.22 However, there is a report of a 39-year-old man having a life-threatening allergic reaction after consuming high amounts of inulin from multiple sources.23 Allergy to inulin in this individual was confirmed by laboratory tests. Such sensitivities are exceedingly rare. Moreover, this man did not take burdock. Nevertheless, people with a confirmed sensitivity to inulin should avoid burdock. There is one published case report of a severe allergic reaction, apparently due to burdock itself.24
