I have often searched through plant medicine books written by clinical medical plant specialists. When several of these experts recommend the same plant to treat a certain health condition, this guides my choice of medical plants. Sometimes
authors from all over the world recommend the same plant for a health condition. I call this cross-cultural agreement. When several authors use the same plant, it is more likely to be effective. I have entered information from hundreds of books into my database. I selected books written by respected practitioners with experience using the plants to treat real people.
