What Is CBD Oil?
CBD oil is made by extracting cannabidiol[1] from the flowers, leaves, and stalks of a hemp plant. Once the CBD is extracted, it is combined with a carrier oil like hemp, olive, coconut, or medium-chain triglyceride oil to increase absorption.
Unlike delta-9-tetrahydrocannabinol, i.e.THC, CBD does not produce the proverbial high or feelings of euphoria.
How Does CBD Oil Work?
Although scientists still aren’t exactly sure how it works, CBD oil is believed to work by interacting with cannabinoid receptors in our endocannabinoid system,[2] which plays a vital role in our central nervous system.
Studies[3] with depression illustrate well how the endocannabinoid system also regulates and controls many bodily functions, including memory, appetite, immunity, mood, metabolism, and sleep.

Although stevia exhibits strong antioxidant properties, some animal studies[9] suggest it may alter the balance of bacteria in the gut microbiome. However, further research is needed to determine whether this gut microbiota alteration is beneficial, harmful, or neutral.

Additionally, the COA available was completed in 2020 and is no longer valid.
Each tincture costs $67.00 and ships free. If you are unsatisfied with your purchase, you can send it back within 14 days for a full refund, minus shipping costs.
Benefits And Risks Of CBD Oil
Although more long-term studies on humans need to be conducted, current research on CBD has found some promising benefits.
CBD’s ability to calm symptoms of anxiety and depression is perhaps one of its most well-known benefits. One 2022 study[10] on 90 individuals who used CBD to self-treat depression symptoms, such as depressed mood, anxiety, and insomnia, found that 86% said they felt better after CBD treatment. That said, there is still not enough data to conclusively confirm or dismiss the claim that CBD can treat depression and other mental illnesses.
CBD is frequently used to help manage chronic pain. While some studies[11] have shown promising results, research on CBD for chronic pain remains mixed, and additional human studies are needed.
In some cases, CBD can also be used to treat epileptic seizures. The only form of CBD approved by the Food and Drug Administration is Epidiolex,[12] which is used to treat two rare types of epilepsy, Lennox-Gastaut syndrome, and Dravet syndrome. Its use is approved for children.
CBD is generally well-tolerated, with doses of up to 200 milligrams daily being used safely for up to 13 weeks. However, it is not risk-free.
The most common side effects[13] of CBD include:
- Dry mouth.
- Low blood pressure.
- Drowsiness.
- Lightheadedness.
- Mood changes,[14] such as irritability.
- Digestive upset, such as diarrhea or decreased appetite.
Signs of liver damage[13] have also been reported in people who have consumed high amounts of CBD oil, but this information is from post-marketing studies with the prescription form.
CBD is not considered safe to use if you are pregnant or breastfeeding. Animal studies[15] have shown that high doses of CBD in pregnancy can cause reproductive system problems in developing male fetuses.
It is also unclear whether non-prescription CBD products are safe for children.
Lastly, CBD can potentially interact with other medications[13] you’re currently taking, especially those with a “grapefruit warning.” CBD and grapefruit interact with an enzyme necessary for drug metabolism.
How We Choose The Best CBD Oil & Buying Guide
All CBD oils are not created equal. That’s why we prioritized CBD oils made with high-quality hemp extract and which are processed safely.
Here are a few things to consider when shopping for the best CBD oils.
Verify the source. Avoid buying CBD from convenience stores and questionable vendors. Consider purchasing from reputable companies that provide information on growing and manufacturing practices.
Check the extraction method. High-quality CBD oils use supercritical CO2 extraction, the least toxic method.[16] Ethanol extraction is also low in toxicity and preferred over more toxic solvents like hexane.
Look for third-party testing. Look for a trustworthy brand that utilizes third-party testing and provides testing results on its website. Review the type of tests conducted to ensure the CBD oil was tested for potency and heavy metals, solvent residues, microbial contaminants, mycotoxins, and pesticides.
Check the type of CBD oil. Full-spectrum CBD oil is thought to be more beneficial than CBD isolate due to the entourage effect,[17] which theorizes that CBD is more effective when taken alongside other naturally occurring compounds in the cannabis plant. However, it may contain trace amounts of THC, which may cause you to fail a drug test. Broad-spectrum oil and CBD isolate, on the other hand, are entirely free of THC or contain less than 0.01% THC by dry weight.
Where Can You Buy CBD Oil?
CBD oil can be purchased at convenience stores, gas stations, specialty shops, and dispensaries. You can also buy CBD oil online. In addition to being convenient, purchasing CBD oil online allows you to view a specific product’s COA and read customer reviews to decide whether it is worth your money or not.
Final Thought
Although more human research is needed, the current evidence available appears promising. Before purchasing CBD oil, have a conversation with your healthcare provider to determine whether it is right for you.
It’s also vital to do your research and choose a product from a trustworthy brand that conducts third-party testing to ensure your CBD oil will be safe for consumption.
Frequently Asked Questions
CBD oil is generally well tolerated. However, it can cause adverse effects, such as diarrhea, dry mouth, fatigue, and reduced appetite in some people. CBD also has the potential to interact with other medications you’re taking.
Unless otherwise instructed by your healthcare provider, CBD can be used daily.
Yes. The 2018 Farm Bill[18] removed hemp from the Controlled Substances Act, which legalized CBD if it comes from hemp and contains less than 0.3% THC by dry weight.
There is some evidence to suggest that people with anxiety, depression, epilepsy, chronic pain, arthritis, and post-traumatic stress disorder may benefit from using CBD oil.
Taking CBD oil with a high-fat, high-calorie meal may help increase its absorption[19] in your body.
Some CBD oils contain trace amounts of THC, which can lead to a positive drug test.
Unless your healthcare provider recommends a specific dose, it’s best to start with the lowest dose and gradually work your way up over a few weeks until you find a dose that works for you.
CBD oils from CBDfx, Spruce, Joy Organics, Nuleaf Naturals, and CBDistillery are all good choices as they may help reduce performance anxiety and increase blood flow,[20] which may help support stronger erections that last longer.
