There is one published report of Dupuytren’s being cured, fingers suddenly straightened, under the influence of the psychedelic drug LSD (full text: https://dupuytrens.org/DupPDFs/1966_Solursh_1417.pdf). Is this true? Probably not. LSD is a serotonin antagonist, and other serotonin antagonist drugs, such as methysergide, have been shown to cause retroperitoneal and cardiac valve fibrosis. Based on this information, LSD might be exactly the wrong drug to take for other fibrotic conditions such as Dupuytren’s. The search continues.
