Set of 3 Methylene Blue 1% (Methylthioninium chloride) 60ml total

Methylthioninium chloride, commonly called methylene blue/albastru de metil, is a salt used as a dye and as a medication when the blood cannot deliver oxygen where it is needed in the body, antidote for cyanide and carbon monoxide poisoning. This medicine is to be given only by or under the supervision of a doctor. Methylene blue is a thiazine dye. It’s been purchased in Europe a few years ago and I have used it as fabric and hair dye, because it makes beautiful shades of blue and turquoise. However I have purchased too many bottles and because it’s so concentrated to dye something you just need a few drops diluted in water. Selling these as a set of 3. Brand new, never opened.
