FYI ➜ “Non-toxic” doesn’t have a definition, and I use the words chemical-free, toxin, and toxic on Interior Medicine inaccurately. I do this for practical purposes, for now: they’re accessible terms that allow people to find what they’re looking for, and they’re shorthand for a complicated problem. I made an entire (free!) course about this. Check it out here.
