Searching the web, people have been talking about Methylene Blue for PD for at least 10 years. Has anybody tried it? Any details to share?
Edit June 3rd 2022: Yikes! According to RXlist.com you should NOT take Methylene Blue and Levadopa: rxlist.com/drug-interaction...
"methylene blue oral and levodopa oral
methylene blue oral and levodopa oral both increase affecting serotonin levels in the blood. Too much serotonin is a potentially life-threatening situation. Severe signs and symptoms include high blood pressure and increased heart rate that lead to shock. Combination may cause severe harmful effects. If methylene blue must be taken, stop taking the serotonergic drug until 24 hours after finishing methylene blue or after 2 weeks of observation for side effects."
