Last night in Arizona a man died and his wife is in critical condition after hearing quinine may have a roll in a cure.Quinine can only be obtained from a doctor, but they discovered they had a form of quinine that was in tablets used to clean fish tanks. The shared the entire bottle with dire results. Today, doctors are saying the formula in the pills was toxic to humans. Best we follow directions from the medical community even if it seems contradictory at times. Stay safe.
