There are somne homeopathic remedies that I believe in and others I don't. Universally however, I don't think any of these will prevent bird flu. They may ease some of the symptoms and maybe even boost your immune system but they cannot eradicate the virus. My understadning is that it is very robust. So in general, the better your hygiene and the better you take care of yourself in general, the less likely you are to contract it. I imagine there are a lot of homeopathic remedy manufacturers that are going to exploit the bird flu scare to increase sales.
