                                          New plant names needed
The compilation now numbers over 1,300 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you know of a plant to suggest for inclusion, please email the info: local plant name (if known), any known folkloric medicinal use, scientific name (most helpful), and, if possible, a photo. Your help will be greatly appreciated.
