Hemp seed oil

According to a study published in the journal Pharmacognosy Review, hemp seed oil can strengthen the skin barrier and prevent bacterial, viral and fungal infections. It also helps in the management of skin conditions like psoriasis, dermatitis, eczema, lichen planus and acne rosacea.

A randomized controlled trial done on 20 people found that dietary intake of hemp seed oil can improve itchiness and skin dryness associated with atopic dermatitis. The effect was attributed to the balanced intake of omega-3 and omega-6 fatty acids. 

Hemp seed oil contains some amount of cannabidiol. A lab study done in Hungary indicated that the cannabidiol can help manage acne by reducing sebum production and inflammation.

Hemp seed oil is also said to be beneficial for moisturising skin and reducing ageing signs including wrinkles. Though more studies are needed to confirm these effects of the oil.

Hemp seed oil is said to be beneficial for cardiovascular health. However, there isn't much evidence to back these claims.

The oil does contain an amino acid called arginine, a precursor of nitric acid which is essential for maintaing homeostasis, blood pressure and strong blood vessels. However, researchers haven’t found evidence of any significant effects of hemp seed oil consumption on any of these factors. One study found improvement in blood cholesterol level and reduction in coronary artery disease on taking hemp seed oil supplements. 

More studies are needed to understand the effects of hemp seed oil on cardiovascular health.

Hemp seed oil polyphenols are believed to be neuroprotective (protect the nerves). Animal studies show that a compound called phenylproprionamide in hemp seeds has positive effects on memory and cognitive skills. However, more studies are needed to check if hemp seed oil indeed has this effect on cognitive function.
