Ayahuasca and Creativity. Phenomenologically, the effects of ayahuasca are multifarious. They include hallucinatory effects in all perceptual modalities, psychological insights, intellectual ideations, spiritually uplifting, and mystical experiences.
According to Merkur, the sole effect of these substances is the induction of enhanced imagination. I do not think that this is the only effect of these substances, but I do agree that it is a central one.
