Is Dimethyl sulfoxideharmful to Humans?

Dimethyl sulfoxide (DMSO) was discovered as a by-product of the paper making process in Germany in the late 19^th century. It's a colorless liquid that is famous for its ability to penetrate the skin and other biological membranes.

Dimethyl sulfoxide is a laboratory and industrial solvent for numerous gases, synthetic fibers, paint, hydrocarbons, salts, and natural products. Because it is aprotic, relatively inert, nontoxic, and stable at elevated temperatures, it is a commonly used solvent for chemical reactions. Its deuterated form is an ideal solvent for NMR spectroscopy.

Non-prescription Dimethyl sulfoxide is apparently unsafe when applied to the skin. Some non-prescription Dimethyl sulfoxide products might be "industrial grade," which is not intended for human use. These products can contain impurities that can cause health issues. To make matters worse, Dimethyl sulfoxide is easily absorbed through the skin, so it carries these impurities rapidly into the body. Some side effects of taking Dimethyl sulfoxide include skin reactions, dry skin, headache, dizziness, drowsiness, nausea, vomiting, diarrhea, constipation, breathing problems, and allergic reactions. Dimethyl sulfoxide also causes a garlic-like taste and breath and body odor.

Dimethyl sulfoxide is likely safe when applied into the bladder as a prescription medication. Don't use Dimethyl sulfoxide products that are not prescribed by a healthcare professional.

There isn't enough reliable information to know if Dimethyl sulfoxide is safe when given by IV. It might cause side effects such as blood problems, weakness, and confusion.
