, a condition in which various portions of the intestinal tract becomes inflamed.

Half of the participants were given an herbal blend containing wormwood (500 mg three time daily), while the other half were given an identically appearing placebo. Beginning at the second week of the study, researchers began to gradually reduce the steroid dosage given to participants. Over subsequent weeks, most of those given placebo experienced a worsening of symptoms, as would be expected. In contrast, most of those receiving wormwood showed a gradual
These are promising findings. However, it must be kept in mind that a great many treatments that show promise in a single study fail to hold up in subsequent independent testing. Further research will be needed to establish wormwood as a helpful treatment for Crohn’s disease.
Contrary to popular belief, it does not appear that either absinthe or wormwood are notably toxic. No serious side effects were attributed to wormwood in this study.
