If world renowned academic publishers cannot be trusted for simple uncontentious facts then who can. We are not claiming that homeopathy is the one true medicine. We are simply claiming that there is a thing called homeopathy, and in homeopathy there is a treatment called Thuja which uses Thuja occidentalis in its preparation. All of this can be verified easily by entering "thuja" and "homeopathy" into google. It is far from clear what your point is.
