What is CBD Oil?

CBD oil is usually made by extracting CBD from the cannabis plant. The plant extract is then diluted with a carrier oil such a hemp seed oil or coconut oil. It should be noted that the addition of carrier oil is essential in increasing the level of CBD’s bioavailability. For instance, MCT coconut oil helps to protect CBD from breakdown by enzymes. As a result, it usually reaches the bloodstream in its entire composition.

Where Does CBD Come from?

CBD for medicinal use is normally derived from the industrial hemp plant. This is because hemp contains high amounts of cannabidiol content. However, CBD is generally found in all cannabis plants, including marijuana. But for commercial purposes, manufacturers usually avoid extracting this cannabis compound from marijuana because these plants contain high levels of THC psychoactive.

Does CBD Oil Work?

Evidence by consumer reviews as well as research studies by experts indicates that CBD oil works. Its mechanism is based on its interaction with the endocannabinoid system responsible for regulating the process of homeostasis.

While experts are not entirely sure how CBD interacts with the endocannabinoid system, they are sure that this compound doesn’t bind to its receptors, unlike THC. Instead, most of them believe that CBD works to prevent the breakdown of the endocannabinoids found in this system. As a result, it enhances wellness naturally and, therefore, has more effect on the body.

Health Benefits of CBD Oil

The benefits of CBD oil are pretty diverse. Whether you are dealing with mental health issues or physical discomforts, you can use CBD oil can be your go-to solution. So, what can you use CBD oil for? Well, the fact that this product has cannabidiol means that you can use it to treat issues such as:

  • Relieve pain
  • Treat anxiety and depression
  • Cancer treatment
  • Neuroprotective
  • Anti-acne
  • Epilepsy and seizures
  • Alzheimer’s disease
  • Quitting smoking and drug withdrawal symptoms

Relieve Pain

While the understanding of CBD’s role in pain management continues to evolve rapidly, current evidence from animal studies shows that it has excellent pain-relieving effects. This occurs through the organic compound’s interactions and modulation of various systems. This includes the endocannabinoid, pain-sensing, and inflammatory systems.

The science behind CBD’s ability to provide pain relief and treat pain-related symptoms happens when interacting with the cannabinoid receptors. These are the CB1 and CB2 receptors predominantly found in the central nervous system and the peripheral nervous system.

By interacting with these receptors, CBD helps to reduce pain signals. The cannabis compound modulates pain sensations by stimulating the reuptake adenosine neurotransmitter. An increase in adenosine levels in the brain helps to inhibit the feeling of pain sensations.

Secondly, it can work to increase the level of the immune response. CBD can effectively regulate the immune response by reducing the level of the pro-inflammatory cytokines while inhibiting the proliferation of the T-Cells. Lastly, it reduces inflammation that can result in pain since it has antioxidant properties. This makes it effective in treating chronic pain, joint pain, and arthritis, among others.

Treat Anxiety and Depression

If you suffer from panic attacks, anxiety, or depression, CBD oil can be good for your wellness. This is because cannabidiol is highly efficient in managing mental and emotional health problems.

To ease the symptoms of anxiety, CBD has anti-anxiety properties. Both animal and human studies show that it has a positive calming effect on the mind. This is because it affects the limbic and paralimbic brain areas that generally trigger the symptoms of anxiety.

When it comes to depression, cannabidiol has antidepressant properties. Animal and human studies show that its anti-stress and antidepressant activities in the body help to reduce symptoms of depression. Besides that, it’s ideal for short- and long-term use by patients suffering from depression.

Cancer Treatment

You can use CBD oil as a complementary treatment for cancer. It’s worth noting that cancer treatment options such as radiation and chemotherapy usually produce a wide range of side effects. This includes loss of appetite, nausea, and weakness that lead to significant weight loss.

Various research reports show that the cannabinoids found in CBD oil can help to ease nausea and neuropathic pain. A combination of CBD and trace THC content might even be highly effective in reducing chemotherapy-induced nausea symptoms. This is because CBD has potent anti-anxiety and anti-inflammatory properties.

There are currently Nabiximols, a type of cannabis drug, available in some parts of Europe and Canada. The mouth spray features both CBD and THC. Preliminary reports indicate that it’s promising when it comes to treating cancer pain. While it has not been approved for use globally, it’s still subject to ongoing research studies.

Note: before using CBD for cancer treatment, it’s essential that you first consult your doctor. 


CBD can effectively provide the body with neuroprotective properties when used in concentrations ranging between 1 and 10 pm. This means that you can use the oil to manage neurodegenerative disorders since it can reduce signs of oxidative stress and modulate the release of cytokine. Besides that, it can help to increase the release rate of calcium from the glial intracellular and neuronal stores.


Acne is a skin condition that usually occurs when the skin’s hair follicles get plugged with dead skin cells and oil. It can result in pimples, whiteheads, and blackheads. At the same time, it’s a common condition; Acne has no exact cure.

However, it’s possible to use CBD oil to manage the severity of Acne. This organic product can help to stop the fundamental processes that usually lead to Acne. This includes excess oil buildup as well as inflammatory conditions. Research studies indicate that CBD has anti-inflammatory properties and it can help to reduce excess production of sebum. These studies concluded that CBD is indeed a “promising therapeutic agent” that you can use to treat AcneAcne.

Oil products with this cannabis compound work to prevent the progress of AcneAcne but also treat acne scars. Applying such an ointment can help to improve your skin’s appearance significantly, especially when it comes to elasticity and hydration.

Epilepsy and Seizures

Epilepsy is a medical condition that’s characterized by frequent seizures. Medically, these seizures are bursts of electrical activity in the brain that temporarily affects how it usually works.

CBD has currently been approved to treat seizures caused by two rare types of epilepsy and tuberous sclerosis. However, it’s worth noting that early research studies indicate that CBD may have also been influential in treating other forms of epileptic conditions.

A research study done in 2020 indicates that patients taking prescription CBD had almost a 39% reduction in seizures. But how does a product such as CBD oil helps to prevent epileptic seizures?

Well, the exact mechanism of working this organic product isn’t known. However, one clear thing is that the CBD compound found in the oil interacts with the receptors and neurotransmitters found in the endocannabinoid system.

This system works to promotes the process of homeostasis in the body naturally. While CBD doesn’t seem to modify the functions of these systems, it enhances the effectiveness of its components.

When it comes to treating seizures, some animal research studies indicate that CBD has antiseizure properties. Its effects may be due to reducing the neuron excitement that acts on the two groups of receptors that trigger seizures. They include the TRPV1 and GPR55 receptors.

The Food and Drug Administration (FDA) has approved the use of Epidiolex for epilepsy. This is a CBD-based prescription drug that can help to minimize the severe symptoms of Dravet and Lennox-Gastaut syndromes.

This is also an FDA-approved drug that can treat tuberous sclerosis complex, a genetic disorder.

While there is still a need for further research, preliminary results show that CBD oil offers promising results. It’s effective in reducing the severity and frequency of epileptic seizures. The fact that it promotes calmness and relaxation means that people with epilepsy can entirely rely on it.

Alzheimer’s Disease

Knowing what CBD oil will give you a perception of how this organic product can help treat Alzheimer’s disease. Well, how exactly does this occur? While CBD oil can’t fully cure this condition, it can help to reduce its symptoms and reduce its progression.

Recent studies indicate that CBD can help to reduce or remove the severe impact of Alzheimer’s inflammation from the body. Besides that, it has been shown that it effectively reduces the impact of brain cell decline and oxygen buildup.

It’s also worth noting that CBD oil can help reduce the level of body proteins required to eliminate the plaques and dead cells that affect the brains of people with this condition. As a result, it helps to improve motor function and memory.

The brains of patients with Alzheimer’s disease usually show a path of rapid decline and significant destruction. Combining memory loss and other conditions that lead to brain deterioration usually cause an indirect accumulation of oxygen in the brain.

However, the negative impact of oxygen can be countered by using CBD oil. This product has a significant potential of stimulating brain tissue. It can promote brain cells’ new growth and development, leading to improved memory and brain functions.

While there is still a need for more research studies, preliminary lab reports show positive results. But to fully determine the effectiveness of CBD, time and more resources should be allocated for research.

Quitting Smoking and Drug Withdrawal Symptoms 

Quitting smoking isn’t easy. Meanwhile, dealing with withdrawal symptoms is something that a lot of people often struggle with.

A 2013 pilot study, however, indicates that smokers using inhalers with CBD ended up smoking fewer cigarettes. Some even stopped craving nicotine completely. Well, this is a promising outcome that suggests CBD could help people quit smoking.

Another study done in 2018 also established that CBD can help to reduce tobacco cravings. Well, this is mainly due to its relaxing effects. Studies indicate that the organic compound can help reduce some of the symptoms usually associated with substance abuse.

Other Potential Benefits

CBD oil is quite versatile, and it has several other potential benefits, including:

  • Treating asthma and other allergies
  • Managing migraine and cluster headaches
  • Treating insomnia, sleeplessness, and other sleep disorders
  • Improving lung conditions
  • Treating multiple sclerosis
  • Reducing the progress of Parkinson’s disease

How to Use CBD Oil

You can use CBD oil in a variety of ways. Note that you can apply it topically since it’s also available in gels and creams. Besides that, products such as gummies and capsules can be infused with CBD oil. This makes them ideal for oral consumption.

Some tinctures are used sublingually. It would help if you simply placed a few all drops under the tongue, wait for a few seconds and then spit or swallow the oil. Lastly, there are also CBD vape oil products that are made for vaping.

How to Choose the Best CBD Oil

The CBD market is now flooded with many products. While consumer demand has been rapidly increased over the years, more and more brands are also coming up. The increase in demand has led to an increase in supply.

However, there is no specific regulatory body to verify the legitimacy of these brands. So, to choose the best CBD product, then you should consider particular factors such as:

The Source of the Hemp Plant

The location and how the hemp plant is cultivated make a massive difference in determining the quality of the end product. Hemp plants are bio accumulators. So, they usually absorb elements found in their environment. If the farming practices involve pesticides and other toxic chemicals, then these elements will end up in the CBD oil product as well.

To ensure that you choose high-quality CBD oil, consider products from domestic sources and are organically cultivated. You need to choose a product that’s extracted from the US or EU-grown hemp plants.

The Potency

CBD oil’s potency is usually measured in milligrams. Potency helps to determine the concentration of the product and its effectiveness in treating various medical conditions.

It should be noted that the higher the level of concentration, the better the CBD oil’s effectiveness in treating severe medical issues. On the other hand, mild or moderate medical issues require low-moderate potency CBD products.

The Size

In most cases, CBD oil products usually come in 30 ml bottles. However, different brands offer different bottle sizes to sufficiently cater to the different user needs. So, you can choose from 15 ml bottles up to 60 ml bottles.

If you are starting, it’s usually advisable that you get the most miniature bottle possible. This is because you are still figuring out what CBD products are working. So, you shouldn’t waste money on a large bottle that may eventually end up producing unsatisfactory results.

Independent 3rd-Party Lab Results

The most reputable CBD brands in the industry have nothing to hide. They are usually straightforward about their products and typically highlight the type and amount of ingredients they use.

A quality CBD oil product should have undergone stringent lab tests by a 3rd-party laboratory. This is critical in verifying the effectiveness and content of their CBD oil products. Besides that, the 3rd-party lab tests are usually available on the brand’s official website.

The Method of CBD Extraction

The method of CBD extraction matters since its critical in determining the quality of CBD oil. Cheap methods such as those that involve the use of solvents usually lead to low-quality CBD extracts. The industry standard at the moment is the CO2 extraction process. Even though it’s expensive, it’s effective in producing high-quality and contaminant-free CBD oil extracts.

Risks and Side Effects of CBD Oils

The popularity of CBD Oil products has been enhanced mainly by their high level of safety. This organic product has a good safety profile, and you can undoubtedly rely on it. But this doesn’t mean that CBD oils are 100% safe. This is because people react differently to it, and as a result, it possesses certain risks and side effects. common downsides of using CBD oils include:

  • Dry mouth
  • Dizziness
  • Diarrhea and Change in Appetite

Dry mouth

CBD’s dry mouth or cottonmouth effect usually occurs due to the compound’s interaction with the salivary glands. Oral or sublingual utilization of CBD usually interferes with how the salivary gland receptors trigger saliva production.

While this side effect is usually mild-moderate, it’s essential that you count it as soon as possible. To reduce the risk of the dry mouth effect, drink lots of water before, during, and after using CBD oil.


Research studies, as well as some consumer reviews, indicate that CBD oil can result in dizziness. The feeling of lightheadedness usually accompanies these side effects. Well, when you consume an overdose of CBD oil, it may lead to a temporary drop in blood pressure.

Note that this can interfere with your daily productivity. This is because dizziness can interfere with decision-making and result in fatigue.

Diarrhea and Change in Appetite

Oral consumption of CBD oil can interfere with your digestive health and cause a change in appetite. However, these side effects usually occur due to CBD oil overdose or a reaction due to the carrier oils.

For instance, most people react to MCT oil, and if you consume it in high amounts with CBD oil, you might end up experiencing diarrhea. To avoid this side effect, ensure that you check the ingredients on the product label.

Besides, the cannabidiol compound can change your appetite. There are those users that have experienced an appetite increase. Meanwhile, others experienced appetite-suppressing benefits. If you are on a diet or following a specific wellness program, this might interfere with your goals.

Is CBD Legal?

At the federal level, CBD is legal in the US. The legalization of CBD for medicinal purposes was made possible when the 2018 Farm Bill was signed into law. However, some states have not yet implemented the cannabis federal laws. This means that CBD products are still illegal in certain states.

To be on the safe side, make sure that you understand your state laws. It’s also essential that in states where CBD products are legal, the THC content needs to be less than 0.3%.

The Bottom Line
