I think the answer is C)Herbs can provide positive medicinal effect if used properly. C is the best answer because Herbs don't have curing power, they can help you feel better, but they don't have curing powers. This is why A is not the best answer. Herbs may be plants filled vitamins and minerals but that is not that does not really support the author's viewpoint regarding the value of herbal healers. So C would be the best choice. Herbs can provide positive medicinal effects if used properly, and this goes along with the authors views of herbal healers.
