Yeh, that works, and you can make willow bark tea to sub for aspirin., etc.   There's a wealth of herbal solutions for many health issues.  I have an extensive herb garden myself... But that doesn't help my diabetic neighbor.  If the supply chain for pharmaceuticals is interrupted for too long (as China recovers and US manufacturing ramps up), people are gonna die.  It's a powerful lesson about single-supply dependence and one may reasonably extend the lesson to single-payer healthcare.  Pray the lesson isn't too painful in terms of lives.
