Other pain creams contain either anti-inflammatory medications (salicylates or diclofenac) or substances which hide pain behind other sensations like cold (menthol) or heat (capsaicin or camphor).
QR cream contains a natural product derived from sugar called mannitol.
Years ago, Dr. Bertrand started injecting mannitol around nerves carrying pain signals to the brain.
Before the needle was out of the skin the pain had disappeared.
Mannitol worked faster to remove pain than local anaesthetics and the pain relief was longer-lasting.
Unlike local anaesthetics, mannitol did not take away any other feeling like touch or pressure or vibration.
It just removed pain.
