anyway, activated, not DIY charcoal, probably would have been a great thing for Jinx to take 17 years ago 30 minutes after he swallowed the thermometer, but that isn't exactly his complaint anymore.

Charcoal in your stomach daily will absorb nutrients as well possible toxins, not really helpful at all for the long term unless you need malnutrion problems also. Highly unlikely much of it enters the bloodstream, that really isn't what it's used for. It's used mostly for immediate poisoning scenarios. EDTA, which is not easily absorbed, they say only about 10% if you're lucky, and even some DMSA, which is well absorbed (and why it's highly recommended for mercury/lead in the blood), remains in your stomach for a while after taking which is why it's advised to take 2-3 days off each week to supplement without the interference of chelation binders.

Personally anon, your posting of such dubious links to backyard charcoal are a bit of insult to the intelligence of Jinx and the rest of us, who need good help right now, not cheap help.
