Updated in November 2004 to add notes about new research.

Thank you for your feedback.


Amanita Note: We have had some people be confused by this question. Our inclusion of the question about a. muscaria does NOT mean that they should be considered a treatment for cluster headaches. They do not contain the same chemicals as psilocybe species mushrooms.
