Mankind cannot survive without the nutritional and medicinal properties of plants. The number of plant species on Earth has been estimated at around 400,000, with many of these species remaining unknown to humans. While only a fraction have been identified and categorized by Western botanists, it is safe to say that many of the plants unknown in the West are known to indigenous people living within the plants natural ranges.All ancient and indigenous peoples insist their knowledge of plant medicines comes from the plants themselves and not through trial-and-error experimentation. Less well known is that these plant teachings are at the basis of many of the modern discoveries in both medicine and in plant foods.
