When I'm seriously ill, I'll always go to a regular doctor, but for things like a dry throat or allergies or if you just under the weather, I'll always go here first. Daniel Gagnon is apparently a world-class expert in herbs, does a lot of his own research and formulations. Allergy ReLeaf really helped me at the beginning of the juniper season here, and I'm thinking about Singer's Saving Grace --but don't worry, I won't sing!
