Chloroquine is a long approved drug - it was approved well before we knew *how* it worked ... Now, its under investigation for CoVID-19 ... we think it enhanced the effect of serum Zinc on SARS-CoV-2 ... Chloroquine allows Zinc ions in blood serum to more effectively cross the cell membrane, where the *ZINC* interferes with retrovirus machinery ... it also has an effect of reducing the immune response which is why its used in Rheumatoid Arthritis and Lupus ... this seems promising since CoVID-19 kills frequently due to a "cytokine storm" caused by a immune system on hyperdrive ... A natural relative of Cholorquine (hyrdroxychloroquine sulfate) with much the same biological function - Quinine - is used in Tonic water *at very low doses* ... My ancestor's oppressors from the British Empire used to say "G&Ts - Quinine for the malaria, Gin for the boredom"
What is not known about Chloroquine is the "Effective Dose Level" - in other words "how much do folks need to take for 50% to have the effect" ... what we do know is that the ED50 is close to the LD50 ... duh duh daaah - the Lethal Dose Level ... When I was younger, I had to take Chloroquine as an anti-malarial ... this drug has crazy side-effects ... I remember hallucinating and having routine nightmares ... This is not a drug to fool around with - some folks have died already trying to bio hack this themselves Therapeutic Index ("TI") is ED50/LD50 ... Safe drugs have a high TI ... Chloroquine has a very low TI ... google it and wait for the CDC to finish testing before ingesting Fish Tank cleaner!
