Hemp Oil and Atopic Dermatitis (eczema)

Hempseed oil is known as a rich and balanced source of omega-6 and omega-3 polyunsaturated fatty acids (PUFAs). Anecdotal evidence has indicated that dietary hempseed oil may be a useful treatment for remediating symptoms of atopic dermatitis (eczema), due to hempseed oils lipid profile being so similar to the lipid profile of human skin. 

To test this theory, a comparative study was conducted, comparing hempseed oil and olive oil which was given to patients via dietary form over a 20-week period with atopic patients. 

The fatty acid profiles were measured in plasma triglyceride, cholesteryl and phospholipid fractions. A patient questionnaire provided additional information on skin dryness, itchiness, and usage of dermal medications. Skin transepidermal water loss (TEWL) was also measured.

The study concluded that dietary hempseed oil caused significant changes in plasma fatty acid profiles and improved clinical symptoms of atopic dermatitis. It is suggested that these improvements resulted from the balanced and abundant supply of PUFAs in this hempseed oil.

It was also mentioned that individuals who have used hempseed oil for longer periods of time report increased strength in finger nails (months) and thicker hair (years), in addition to the improvements in skin conditions within weeks. The times required for these varied effects roughly corresponded to the amounts of time required for the newly formed cells of each tissue to become physically apparent. 

These three cell lines are constructed by dermal stem cells from fatty acids that are available in the diet at the time of their formation. Here is yet another interesting facet to consider in the complexity of tissue formation.
