Kalevala, mythology, philosophy: for a better understanding of nature. The know-how folk healers possess has been passed from one family to another, from one spirit to another. It has existed for as long as human beings have existed. The folk healers of today keep up this living tradition. Over the years, treatments have been modified to meet the modern standards, but folk medicine is still based on the traditions of our common ancestors. Folk medicine is natural health care at its best.
