Your question got me thinking.

I've just ordered a few grams of methylene blue. I don't think it's something you'd take regularly or for prolonged periods, but if in a state of dis-ease, it does appear to be a magic bullet of sorts.

It seems to be a pretty useful all round & benign drug for acute biological threats:

- treating poisons
- inflammation
- mitochondria dysfunction
- cancer (restores mitochondrial function)
- antimicrobial & antiviral (dengue fever treatment)

I tried it once 5 years ago & I didn't like the chemical taste. I do think it's something that is useful to have on hand.

This is where I sourced it - cztl.bz 

 I got the methylene blue but I've been drawn to chlorine dioxide.

It's a big rabbit hole & looks to be worth exploring.

Low risk & very high return if true.

Not dead yet.
