Just want to throw the enzyme serrapeptase out into the ethers as an additional or alternative treatment of Covid. "Serrapeptase was recently shown to exert antiviral effects by digesting proteins that coat the virus."  Originally used (for centuries) as a particularly useful enzyme for breaking down scar tissue, thinning mucus, and clearing airways.  It has many additional uses most of which can be positively contributed to lessening Covid symptoms.  I encourage anyone interested to do their own research as I doubt any big pharma or government agency will be promoting any functional product that is tried and true, natural and low cost.
