Dimethyl sulfoxide (DMSO for short) is a organic sulphur compoundwhich has been used for decades in medicine, animal care and technology. It is a Colorless liquid with a characteristic odorwhich is characterized by a particularly high solution capability.

• DMSO CAS number: 67-68-5
• DMSO PubChem CID:679
• DMSO molecular formula: C₂H₆OS
• other names:Methyl sulfoxide, Sulfinyl bismethane, Methylsulfinylmethane, Dimexide and the Latin name Dimethylis sulfoxidum

DMSO is versatile - among others as:
• Solvent in laboratory and technology
- Excipient in research
- Care and cleaning products in the animal and plant sector

Raw materials:
- Dimethyl sulfide (DMS): a by-product of the pulp and paper industry (produced during the processing of wood).
- Oxygen: is used for oxidation.

processed and bottled in the Switzerland from MYCHEM

As DMSO is obtained from natural raw materials, the odor may differ slightly depending on the batch. This has no influence on the purity or quality.

Lara's Tip:

Against Chronic tendinitis in the fingers and wrist. Also very effective against weather-related pain in operated joints. In case of pain, rub 10-15 drops onto the affected area and repeat 2-3 times a day.

Against herpes virus blisters
If you notice that herpes is appearing, whether on the lips or other areas, dab a few drops onto the affected area 2-3 times a day and allow to dry. Do this from the first sign. This can halve the healing time of the annoying herpes outbreak, depending on its severity.

DMSO must be stored at room temperature, in the refrigerator it freezes depending on the concentration!
