I only had time to glance at it. I couldn't see what exactly they studied. There are lots of FDA approved drugs that turn out to be harmful. Anyone doing a study can choose how to do it, and they may not do it right. Even among homeopaths, there is disagreement on the "right" was to prescribe and to dose. Some people use the little pellets straight, some insist the pellet has to be dissolved in water. Some just don't know how to recognize symptoms and then can't possibly select the right remedy. I took one dog to 2 vets. They both had very good reputations in the holistic community, one was even nationally known. They each prescribed a different remedy for the dog and neither was helpful. It wasn't until a few years after that, when I really started to learn about homeopathy, that I realized those vets didn't really understand homeopathy and that was why they couldn't use it correctly. When I occasionally need to take one of my kids (11, 14, 16) to the doctor, the doctors are surprised to find out that the kids have never had antibiotics, ibuprofen, Tylenol, cough medicine, allergy medicine, etc. Several years ago, the doctor said 2 of them had ear infections and they needed antibiotics. I took them home, gave them a remedy, and about an hour later they were better. People can be affected by placebos (which all medicine can fall in that category), but animals can't. No study can convince me that what I have lived for the past 10+ years wasn't real.
