Proflavine sulphate is a synthetic acridinedye of red-brown crystals, soluble in water, used as a powerful and effective antiseptic during the Second World War to treat battle casulties and later in hospitals, but is much less used now as a result of the pharmaceutical companies pushing for the use of antibiotics instead. Attempts to prove that proflavine causes cancer, have so far proved negative though the pharmaceutical industries still cite this as a reason not to use it. The effectiveness of proflavine is amazing, a wound dressed with proflavine over night usually shows a marked improvement the following morning, where as antibiotics can typically take days to take effect and have the unfortunate side effect of lowering the body's natural immune system which with prolonged usage leads to permanent damage.
