The Upjohn Pill and Granule Company
sold so many quinine pills in the early years of the twentieth
century they became known as the quinine company. Quinine is
used to treat malaria and was a very important drug when
Europeans and Americans were romping through the jungles of the
world. Even in the US, malaria was a big problem for the early
settlers until millions of acres of swamps and marshes were
drained, thus reducing the breeding grounds for mosquitos.
Quinine is no longer the first choice for treatment of malaria
due to side-effects but for resistant cases it is still used.
