In the north of Peru the power of San Pedro works in combination with tobacco. Also the sacred lakes Las Huaringas are very important. This is where we go to find the most powerful healing herbs which we use to energize our people. For example we use dominio [linking one's intent with the spirit power of the plants] to give strength and protection from supernatural forces such as sorcery and negative thoughts. It is also put into the seguros – amulet bottles filled with perfume, plants and seeds gathered from Las Huaringas. You keep them in your home for protection and to make your life go well. These plants do not have any secondary effects on the nervous system, nor do they provoke hallucinations. San Pedro has strength and is mildly hallucinatory, but you cannot become addicted. It doesn’t do any harm to your body, rather it helps the maestro to see what the problem is with his patient. Of course some people have this gift born in them – as our ancestors used to say, it is in the blood of a shaman.
