Majority of cannabinoids have been shown to have positive effects on the immune system, particularly the CBD oil, as it helps regulate over-active immune systems. This basically means less susceptibility to various kinds of allergens. Moreover, since CBD oil contains a high amount of omega 3 which supports the growth of micro organisms which live in the intestines, it can aid in enhancement of the immune system, and your body will be able to fight flu, illnesses and germs more easily.
The passage of the 2018 Farm Bill made it legal to sell hemp and hemp products in the U.S. But that doesn't mean that all hemp-derived cannabidiol products are legal. Since cannabidiol has been studied as a new drug, it can't be legally included in foods or dietary supplements. Also, cannabidiol can't be included in products marketed with therapeutic claims. Cannabidiol can only be included in "cosmetic" products and only if it contains less than 0.3% THC. But there are still products labeled as dietary supplements on the market that contain cannabidiol. The amount of cannabidiol contained in these products is not always reported accurately on the product label.
