Re: “De wonder chemical of yore!”
Interesting phrasing - given that, once upon a time, I used DMSO frequently. As you said, it's a wonder drug... er... chemical.

I used to do a lot of hiking and tennis playing. In consequence, I sprained my ankles once or twice yearly over a long period. I once went to Emergency, not knowing if an ankle was sprained or broken, and had my SPRAINED ankle put in a cast for six weeks. You can infer from this that my sprains were severe.

After discovering DMSO and applying it topically two or three times over the course of an hour, I never again had a sprain where I wasn't able to walk pretty normally, with little pain, the next morning.

When I was a teenager, I used to get boils on my nose. They'd stick around for a week or more and look horrible if I didn't lance 'em. With DMSO and no lancing, they were on the run the next day. Great stuff!

Also, I imagine, dangerous stuff. DMSO is a powerful industrial solvent. In pure form, it will dissolve the source of swelling and carry it away in the blood, right quick. I used to marvel at how I could put it on my ankle or foot and, in a matter of a minute or two, TASTE it. (It has an onion flavor.) Miraculously, it does this without any apparent side effects.

But DMSO, dabbed on your skin, enters the bloodstream almost immediately dissolving just as quickly. If you have ink on your fingers and get a little DMSO on them, you've just given yourself some ugly tattoos.

Just imagine what would happen if the DMSO itself was ever contaminated. I bet a person could die that way very easily.

This is a MAJOR breakthrough. PFAS have spread until they are now found AT TOXIC LEVELS in RAINWATER, literally all around the world (even the north and south poles!) And then they go into the rivers and streams and groundwater supplies.

So imagine my delight when I was reading Science and stumbled on this article!

DMSO, which some of us have used for health reasons, combined with simple lye (NaOH) and heated to 250 F tears apart the "forever" PFAS within hours. That still requires processing, but at least it gives a practical solution to a growing problem which should concern us all!

Good old DymethlySulfoxide! De wonder chemical of yore!

Per- and polyfluoroalkyl substances (PFAS) have been referred to as “forever chemicals” because of their resistance to most biological and chemical degradation mechanisms. Most current methods use very harsh conditions to decompose these compounds. Trang et al. found that there is a potential weak spot in carboxylic acid–containing PFAS: Decarboxylation in polar, non-protic solvents yields a carbanion that rapidly decomposes (see the Perspective by Joudan and Lundgren). The authors used computational work and experiments to show that this process involves fluoride elimination, hydroxide addition, and carbon–carbon bond scission. The initial decarboxylation step is rate limiting, and subsequent defluorination and chain shortening steps occur through a series of low barrier steps. The procedure can accommodate perfluoroether carboxylic acids, although sulfonic acids are not currently compatible. —MAF
