Glass bottle, containing ammoniated quinine tablets from George Mackie Glasgow

Ammoniated quinine is a mixture of quinine sulphate and ammonium carbonate. Thesse tablets were a replacement for a liquid version of the medicine. According to the makers a tablet should be taken every three to four hours. It was recommended for use during colds and flu. Quinine was believed to have fever-reducing qualities as a result of its use for malaria. Research has shown that quinine's effect is on the malaria causing parasite.

Ammoniated quinine tablets were subject to scrutiny as varying levels of ammonia carbonate were found and raised questions over its effective as a replacement for liquid forms.
