Sponsor: MAPS Inspired by reports from the cluster headache community that ingestion of seeds containing LSA (Hawaiian baby woodrose, morning glory, Rivea corymbosa) terminates cluster periods in the same way that LSD and psilocybin do, this study will examine the effects of LSA on cluster headache by collecting accounts from patients who have used these seeds to control their symptoms, and will also analyze the seeds that they used in order to determine the LSA content.
