Part autobiography, part introduction to entheogens and visionary substances, The Toad of Dawn gives an overview of the history, use, and the benefits of the toad medicine, and reveals how it can be used to initiate people on a spiritual path. In The Toad of Dawn Dr. Rettig Hinojosa shows that 5meO-DMT derived from the secretion of the Sonoran Desert Toad is the most profound, most healing entheogen available, even more so than Ayahuasca, LSD, DMT, Psilocybin etc. The author thinks of it as the Master of all entheogens, the one thing that brings someone closest to God, the Divine Source, to the big meaning behind all, and declares it to be the most powerful healer on this planet. The most significant contribution to entheogenic literature since Jeremy Narby's The Cosmic Serpent. - Scott Olson.
