I'm a medical doctor and I've come to test this exciting new technology. I had a great experience all the way through while spending one night at Alkimia pura. I didn't come with any major illness and only 24hrs have passed, so I cannot fully evaluate healing as yet. I can say that My friend has healed his chronic fatigue syndrome with one 10hrs session! also you do feel the frequencies! It feels like being sitting at the bottom of a swimming pool, the air is thick from the frequencies and it feels on the skin. The owner is fantastic. The place is very conveniently located. I want to keep pursuing testing the machines as I believe it is a Very Promising therapy.
