648 patient RCT pHOXWELL nasal spray in India, showing significantly lower IgGS+ and significantly lower symptomatic cases with treatment.pHOXWELL includes a combination of natural virucidal agents and is designed to mimic the fluid surrounding healthy cells. The spray included xylitol, zinc chloride, polyethylene glycol 400, poloxamer, disodium hydrogen phosphate, sodium chloride, hydroxypropyl methylcellulose, ginger oil, eucalyptus oil, basil oil, clove oil, sodium hydrogen carbonate, potassium dihydrogen phosphate, ethylenediaminetetraacetic acid, sodium hyaluronate, calcium chloride dihydrate, benzalkonium chloride, magnesium chloride hexahydrate, potassium chloride, and glycerol. The spray was administered up to three times per day (TID) 140 μl/nostril for 45 days, with a gap of 6-8 hours between doses.
