The specific drug studied was diphenhydramine (Benadryl), which Ray Peat recommends for several problems including endotoxin protection and liver support.

However, I have seen pretty similar results for cyproheptadine, which is also antihistamine in action.

So, it seems that this may be a general property of the antihistamines. I wonder what the mechanism of action is. Based on Peat's ideas anxiety/PTSD/panic are probably caused by serotonin so that explains why cyproheptadine is effective since it's a general serotonin inverse agonist. But if Benadryl is working as well, then does that imply Benadryl has anti-serotonin action as well???
Maybe somebody already exchanged emails with Peat on Benadryl and how he thinks the drug achieves its effects. So, please share what you know.
