If you just eat naturally you never get sick in the first place, it is not normal to get sick. You do not need any supplements and Quercetin and hydroxychloroquine are man made poisons and can harm the body (kidneys), It activates the immune system because it is another type of poison your body has to fight off… the whole ‘activating the immune system’ schtick is a lie! You do not need to activate anything, if you are healthy the immune system just ‘is’ and works.
