Also from the report mentioned numerous times throughout the post's thread:

Finally, due to these protective qualities, DMSO’s toxicity is extremely low (e.g., due to the immense scrutiny DMSO has been subject to, a large number of animal safety studies were conducted, and in these, animals survived extraordinarily high doses of DMSO). Many human studies have also been done, the most significant of which involved 78 prisoners over the course of 14 and then 90 days applying 1 g/kg to their skin (over 3-30 times the maximum amount of DMSO typically used) and then being subject to an extensive battery of toxicology tests—all of which showed DMSO was safe. In turn, despite millions of treatments having been given, no death has ever been linked to DMSO (and the only two ever considered, one in 1965, and one in 1994 did not make a strong case DMSO was the cause of death). Note: thousands of papers have been published on the biological effects of DMSO and I have not yet found one that reported an adverse event from DMSO. Because of that, I’ve mostly avoided mentioning each study I site here, “detected no adverse events from DMSO.”

I'm guessing you didn't read the post's actual thread or the report mentioned numerous times throughout the post's actual thread. They're the sauce. From the report:

Cellular Protection

DMSO’s ability to spread throughout the body (including into the brain) initially seems concerning—however rather than be toxic to cells, DMSO heals them and protects them from damage and a wide range of otherwise lethal stressors. Since DMSO does not expand when it freezes (at 65.4°F), this property (and the fact that a 66% DMSO 33% water mixture freezes at -99.4°F), has made it a revolutionary substance for preserving frozen cells (e.g., stem cells). In contrast, very few other substances exist that cells can tolerate such a high concentration of.
