Covid-19 and Tonic Water

Long ago the British learned while in India that quinine was useful in fighting malaria, but because quinine derived from the bark of the South American cinchona tree is not very tasty they dreamed up a mixed drink of gin and tonic that was less offensive to the taste buds to give to their soldiers and staff.

Chloroquine is the synthetic version of quinine and some tests claim to be a possible remedy to the Covid 19,  coronavirus.  Most grocery stores carry various brands of tonic water but not all contain quinine (read the fine print).  It has been found to help with leg cramps and restless legs at night.
