Can magnesium chloride help with psoriasis?

Natural products and therapies


As discussed in a previous answer, swimming in the Dead Sea can help with some psoriasis symptoms. Since the Dead Sea salts are rich in magnesium chloride, some people think that they can help with psoriasis. However, the benefits of bathing in the Dead Sea come mostly from exposure to the sun and relaxation. Magnesium chloride itself has not been shown to be useful with psoriasis symptoms.

Dr. Marc Bourcier:

Magnesium chloride is a compound that some people claim has value for various health conditions. It can be used topically or ingested in a solution. However, no serious study has shown that magnesium chloride can help with psoriasis. We have anecdotal reports at best, but not even a lot of them.

As long as no double blind, peer-reviews study has been conducted, we cannot recommend this as a form of treatment for psoriasis.

Magnesium salts (magnesium chloride) are minerals found in abundance in locations such as The Dead Sea. These salts are noted to have anti-inflammatory properties and there is some scientific evidence to support this. In a study conducted in Switzerland, researchers examined the effect of bathing in magnesium chloride obtained from the Dead Sea on people with dermatitis. Dermatitis is a broad term that generally refers to an inflammation of the skin. The findings of the study showed that skin roughness and redness of the skin (signs of inflammation) were significantly reduced after bathing in the salt solution. The researchers suggested that the favorable effects of bathing in the Dead Sea salt solution are most likely related to the high magnesium content.

However, psoriasis is not dermatitis, and the positive effects of magnesium chloride have not been proven for psoriasis.

No, there is no evidence that magnesium chloride can help psoriasis. Some people think that magnesium chloride salts are helpful for psoriasis because Dead Sea salts are high in magnesium. Relaxing at the spa at the Dead Sea is helpful for psoriasis but it is not only the salt water that is helping; relaxation and the sun are also very beneficial. Dead Sea salts can be purchased and used in your bath tub, but they are probably no more beneficial than other salts. Soaking in a salt bath (about one cup per tub of water) can help to lift the scale from the psoriasis. Be careful not to scrub and exfoliate your skin as it can make the psoriasis much harder to treat. Make sure you moisturize immediately after getting out of the tub and patting your skin dry. Since salt is highly corrosive, this may have an effect on your plumbing so be sure to run the tap to clear the drain after your bath.
