By definition, ointments must be infused with medicine, in this case CBD, and are of a semi-solid almost mucus-like consistency. Creams typically involve water or some type of aqueous substance as their base, while salves utilize only oils or waxes for their foundation. Ointments tend to contain a combination of oils, water and alcohols within their formulation.

High-CBD strains tend to deliver very clear-headed, functional effects without the euphoric high associated with high-THC strains. They’re typically preferred by consumers who are extremely sensitive to the side effects of THC (e.g., anxiety, paranoia, dizziness). A high-CBD strain would also be a great choice for someone needing to medicate throughout the day to control pain, inflammation, anxiety, or other chronic conditions.

It is well known that cannabis plants obtained from uncontrolled sources may be contaminated with various harmful substances [39], sometimes leading to severe health issues or hospitalization [40]. Contaminants include chemicals that were intentionally added in order to increase yield, weight, or potency (e.g., pesticides, metal particles [41], synthetic cannabinoids [42]) but also agents that entered the plant unintentionally (e.g., heavy metals, molds and bacteria [43], aflatoxins). For example, pesticides are frequently present in cannabis sold by Dutch coffee shops [44], but were also found in cannabis offered under state law in California [45] as well as medicinal cannabis from licensed producers in Canada [46]. If any of these contaminants were present in hemp used for CBD extraction, they would likely end up in a concentrated form in the final oil. One contaminant specifically relevant to cannabis (CBD or THC) oils is the residual presence of toxic solvents used during the extraction procedure [3].
NuLeaf Naturals CBD oil tinctures are all full spectrum; it is 100% organic and never made with herbicides, pesticides, or chemical fertilizers. The brand offers a full spectrum pet CBD oil tincture, as well. NuLeaf Naturals offers free shipping to all 50 states; the brand’s products are also sold in more than 200 retail locations across the country.
Because it does not produce psychoactive effects and hemp is not a controlled substance, hemp-based products are legal to sell, buy, and possess in all 50 states. However, the law is a bit more complex when discussing CBD oils and other hemp byproducts. According to the 2014 Farm Bill, hemp should only be grown and cultivated for academic research purposes. This means that, technically, any hemp-derived oil that is not grown for these purposes would be illegal — though this law is rarely enforced. To make matters more complex, the laws are somewhat unclear in certain states. Sen. Mitch McConnell of Kentucky recently introduced legislation that would legalize all hemp products at the federal level, but this decision is still pending.

The following medications and other supplements may interact with CBD. Effects may include increasing or decreasing sleepiness and drowsiness, interfering with the effectiveness of the medications or supplements, and interfering with the condition that is being treated by the medication or supplement. These are lists of commonly used medications and supplements that have scientifically identified interactions with CBD. People who take these or any other medications and supplements should consult with a physician before beginning to use CBD.


Though unflavored and priced higher than competitors, Green Roads CBD oils are made by a trusted manufacturer and use organically grown hemp. Following the CO2 supercritical fluid extraction process, board-certified pharmacists formulate the tincture by hand. Green Roads only sells CBD isolates, so if you’re looking for broad-spectrum products look to some of our other recommendations.
