Chloroquine May Fight Covid-19—and Silicon Valley's Into.. Dr. Rigano said their study found that those COVID-19 patients who took hydroxy-chloroquine were found free of the disease in 6 days. The patients were testing negative for the coronavirus in six days! Dr. Rigano also said taking choroquine could act as a preventative. This is a remarkable study! Chloroquine isn’t new. Its use dates back to World War II, and it’s derived from the bark of the Chinchona tree, like quinine, a centuries-old antimalarial. Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat amebiasis, an infection of the intestines caused by a parasite.
