Toxic

Severe Toxicity

Ptychoverpa bohemica contains monomethylhydrazine (MMH), a toxic compound also found in Gyromitra esculenta (False Morel). MMH can cause gastrointestinal distress and neurological symptoms. Proper cooking reduces the MMH content; however, individual sensitivity varies, and complete removal of the toxin is never guaranteed.

Toxin Type: Monomethylhydrazine (MMH)Reaction Type: Gastrointestinal distress, neurological effects
