A very good overview, but it's written rather blandly.

A complete guide on how to treat different allergies. This article covers different types of reactions and how to treat each one effectively.

This is a good quick-reference article. It presents fairly comprehensive information, but doesn't overwhelm the reader. I also like the fact that they talk about specific medications, but do not exactly favor any of them. It allows the reader to bring information about dfferent medications to their doctor, but doesn't seem to be selling the reader on a specific treatment.
