Ann: First Commercial Order from Country Farms/Starbucks, page-46

That's great news. The trouble with HCT is that they don't back their claims with real-world scientific studies until every player in the game has gotten ahead of them and they can no longer make a market leading impact. This is what happened with the HVAC and Natshield. It did work against the human strain but they did the studies and released the science too late to make an impact in market share. They failed to get TGA approval in Australia, making it just about worthless to any government organisation or organisation that needs to satisfy government criteria (lets just say everyone).

So yes, HCT have a product that aims to control COVID-19 within one of the key environments where it grows and spreads from, the nose, but who knows or even cares about it other than shareholders because the company have not obtained effectiveness data and have not marketed it aggressively enough.
