God's Healing Leaves

With all of the myriads of books on alternative healing and books on herbology that are on the market today, why would anyone want to write one more? As a Christian, I believe that God created the universe. He then created the plants for our use. Yet, when I would look in the herbology textbooks that had been written and compiled thus far, I constantly found that they contained information from spiritualistic or New Age sources. I can only ascribe to Christian theories. I believe that God is our Creator and that it is His intention for us to use His natural medicines. Neither I do not believe that these plants are here by accident, nor do I believe that they are here due to some mystical position and negative forces.
