There are many wonderful websites on the Internet with information about natural personal and environmental health. The pages on this site are a little different. They organize topics into page-at-a-glance "maps" as guides to relevant Internet sites and documents. You may look at a map to grasp an overview of a topic or follow hyperlinks to get deeper into your study.
The maps, in other words, are not simple images; they are portals. Click over any map image be redirected to its hyperlinked PDF version.
The red stars on the maps indicate newest links, not necessarily the most important ones. As maps are link-checked and updated, the starred links will naturally change. You have the option to see what has changed since your last visit.
