Hi KatyPiee
I would consider a vitamin A based approach... I'll explain..
Most of the body’s immune system is directly linked to the gut. When bugs make holes in the gut wall, harmful microbes, toxins, undigested foods and other foreign substances that should be restricted to the gut end up leaking into the blood. This can trigger an inflammatory response i.e. eczema.
In eczema, the skin experiences a “leaky” damage similar to the one found in the gut. This leaky skin damage is caused by pathogens colonising the skin's surface and gland ducts.
Vitamin A and its analogues reduce bacterial population in the skin but also in the gland ducts of the skin. This means that vitamin A compounds can help restore the protective barrier of the skin by stopping the bacterial damage that leads to leaky skin. In addition, vitamin A can relieve eczema by reducing local inflammation in the skin.
One of the most effective drugs for treating acne is isotretinoin (a vitamin A analogue). A related drug known as alitretinoin (taken orally) is also approved for the treatment of severe hand eczema in Europe and Canada.
Although vitamin A has no direct antimicrobial effect, it plays an important role in the immune system defence against invading microbes. It boosts the immune system and helps reduce the effect of leaky gut syndrome in the development of eczema.
Cod liver oil is one of the few ideal natural supplements that can be safely used to raise the vitamin A level in eczema patients. The vitamin A content of cod liver oil is sufficient to make up the daily recommended intake of the vitamin. (You would need to ensure you don't exceed levels as vitamin A can be toxic). Therefore, cod liver oil can be used solely as a vitamin A supplement and is a good source of omega-3 fatty acids.Omega-3 fatty acids are known for their anti-inflammatory properties. In addition, these essential fatty acids can improve skin health and restore the gut flora.
In summary, consider vitamin A topically and orally.
I hope this has helped..
