Sharing because I found this very interesting.
The Four Thieves Vinegar Collective has a DIY design for a home lab you can set up to reproduce expensive medication for dirt cheap, producing medication like that used to cure Hepatitis C, along with software they developed that can be used to create chemical compounds out of common household materials.
There is a difference between knowing which medicines to give someone. And then having that knowledge of which to choose (after seeing a healthcare professional), and then being able to buy (make) any brand of that item.
