Proposal for potential efficacy in using Methylene blue as an MAOI in Pharmahuasca.
It has come to my attention that the dye Methylene Blue* (MB) is a potent MAOI inhibitor ([1]R R Ramsay, C Dunford, P K Gillman. (2009)) causing severe side effects at a dose of less than 5mg/kg** with co-consumption of serotonergic drugs ([2]C. Schwiebert, C. Irving, P. K. Gillman. (2009)). These effects of the drug may lead it to become a useful tool in the preparation of Pharmahuasca.
Potential Pros to using MB in Pharmahuasca
- High potency
- MAOI A affinity ***
- Reasonably accessible
- Cool colour
- long history of medical use
- 5hr half life*****
- High potency
- Reasonably accessible
- Can cause hypertension****
- Can cause immunoglobulin hypersensitive reaction*****
- Can cause anaphylactic*****
- Can cause Serotonin syndrome*****
- (ofc) should not be used during pregnancy*****
* Methylene blue (cas number 61-73-4) not to be confused with Methyl blue (cas number 28983-56-4)
** Do not take more than 1-2mg/kg (although keep in mind I'm just making an "educated" guess here)
