honestly, everyone one in their right mind would be more than happy to swish and spit for at least five minutes at a time for as may times as it took if it saved our health and lives. IMO it's an extremely minor inconvenience if there's a reasonable chance it prevents or greatly diminishes a debilitating or fatal condition.
I had actually had the same thought. What if it could be used as a daily mouth wash for treatment/prevention of periodontal conditions since bacteria/inflammation are drivers of that disease process.
