“People testing ayahuasca will gain much from reading this book before take-off. Chris Kilham knows his plants, his writing is fun, and the book itself is packed with knowledge.”

“Ayahuasca is the greatest of enigmas.

The very notion of trial and error falls apart. Shamans uniformly insist that the plants communicate their uses directly.”
