CBD Oil: What is it?

You have probably heard about cannabidiol (CBD) oil from a friend or a coworker, and you may be wondering now what it actually is and are there any benefits of using CBD oil if it is legal to use in the United States. In this blog, we will try to answer all the questions you have about the it.   


What is CBD oil?  

CBD oil is just like ordinary oil; the only difference is that it contains CBD. Manufacturers of CBD oil add CBD extract into a carrier oil, which is usually coconut or hemp oil. CBD is the non-psychoactive component of the cannabis plant, which is why it does not produce a high effect and does not make you feel intoxicated.   


Are there any types of CBD oil?  

There are three main types of CBD oil:  

CBD isolate oil  

CBD isolate oil only contains CBD; the other 113 cannabinoids of the cannabis plants are not included in CBD isolate oil or other products. If you only want to consume CBD and do not want to try any other cannabinoids of the cannabis plant, CBD isolates oil is perfect.   


CBD broad-spectrum oil  

Broad-spectrum CBD oil contains all the cannabinoids found within the cannabis plant, with the exception of tetrahydrocannabinol (THC), which is the psychoactive component of the cannabis plant. If you can’t tolerate THC but want to try all the other cannabinoids of the marijuana plant, then broad-spectrum CBD oil is best for you.   


CBD full-spectrum oil  

Similar to broad-spectrum CBD oil, full-spectrum CBD oil contains all the cannabinoids of the cannabis plant. The only difference is that it contains THC as well. The concentration of THC is around 0.3% in full-spectrum CBD oil, which is not enough to cause a high effect, but it is enough to create the entourage effect. According to data, CBD works best when used with a small amount of THC, so if your healthcare professional thinks that full-spectrum CBD oil is good for you, then give it a try.   


How can you use CBD oil?  

CBD oil is probably the most versatile CBD product, as you can use it in any way you want. If you want to keep it simple, then you can put a few drops of CBD under your tongue using a dropper, hold it in your mouth in a bit and then swallow. This method of using it is known as the sublingual method. If you are a foodie and like to try new foods, then you can create delicious dishes using it.   


If you want to ingest CBD oil but do not want to make food or don’t want to taste the it, then you can use CBD capsules. These capsules are just like normal capsules; the only difference is that they are filled with CBD oil. If you don’t want to ingest it but still want to experience its effects, you can apply CBD oil directly. This method is considered to be the best for reducing inflammation and pain. Inhaling it via a vape pen is another method of using CBD oil; however, it is not recommended because it can cause discomfort in your throat and lungs.   


What are the benefits of using CBD oil?  

There is some data suggesting that CBD oil and other CBD products may be able to benefit our health. CBD may treat epilepsy, alleviate cancer-related symptoms, provide neuroprotection, etc. Other than the benefits mentioned above, CBD also has the following benefits:  


It may provide pain relief   


According to a recent trial, topical application of CBD oil may be effective for reducing sharp and intense pain and itchy and cold sensations in people with peripheral neuropathy of the legs without contributing any side effects. The trial used a 250 mg of CBD dissolved in 3 oz. of oil; it also included a placebo.   


There is an oral spray named Sativex, it contains both CBD and THC and according to a review, it may be effective for treating chronic non-cancer and neuropathic pain. These pain-reducing qualities are due to the anti-inflammatory properties that both CBD and THC possess. Another study about Sativex shows that it decreases inflammation and reduces Disease Activity Score-28 (DAS28).  


It may support heart health  


You can find several studies on the internet that suggest CBD supports heart health, helps us maintain a healthy circulatory system, and regulates the blood pressure. High blood pressure, also known as hypertension, can cause several health issues such as heart attack, stroke, and metabolic syndrome. A study published by the American Society for Clinical Investigation shows that a dosage of 600 mg of CBD is effective for reducing the resting blood pressure in healthy men. After receiving a single dose of CBD, the participants did not experience a significant elevation in their stress levels during a stress test. Before they took the CBD, their stress levels increased significantly. This blood pressure regulating capability of CBD is linked to its ability to reduce anxiety and stress.   


According to another study, CBD may prevent heart damage and reduce oxidative stress in diabetic patients.  


It may relieve anxiety and depression  


Although there is a lack of studies on humans when it comes to studying the effects of CBD on depression, still the animal studies that the researchers have conducted show promising results. CBD may be used for treating mood disorders, according to an article published by Neuropsychopharmacology, CBD reduces the levels of stress and discomfort caused by a stressful situation. The participants also had lower levels of negative self-evaluation during the stress test, which may be possible due to the positive effects of CBD on serotonin receptors.   

CBD is considered to have effects that are similar to anxiolytics and antidepressants, and this is confirmed by an animal study which also reports positive effects of CBD on depression. 


It supports skin health  


There is no doubt about the fact that we all want flawless skin, but due to certain ailments, we can’t get what we want. According to a study conducted by the Journal of Clinical Investigation, CBD may hold the ability to prevent some functions of the sebaceous glands that leads to acne. According to data, there are certain cannabinoids in the cannabis plant that possess anti-inflammatory anti-aging and anti-itch property. These properties are unlocked as a result of the interaction between CBD and the endocannabinoid system (ECS) found in our bodies. This is the main reason CBD is believed to be a potential effective treatment for:  

  • Acne  
  • Pain  
  • Psoriasis  
  • Atopic dermatitis  
  • Itchy skin  
  • Psoriasis  


Are there any side effects of CBD oil?  

The consensus among healthcare experts is that CBD oil is safe to use and when used appropriately, it doesn’t cause any harmful side effects. There are two instances in which the users of it can experience its side effects; if the user is sensitive to other oils, such as coconut, hemp, olive oil, or if you are using substandard CBD products that contain harmful elements.   


CBD interacts with the cannabinoid receptors and these receptors are not located in the brain stem, meaning that CBD can’t alter the respiratory system. The toxic dosage of CBD is considered to be 20,000 mg all consumed at the same time and even after consuming the toxic dose, the person may not experience life-threatening side effects. Still, the side effects will be severe and can include:  

  • Psychosis  
  • Lethargy  
  • Vomiting  
  • Anxiety and depression  
  • Diarrhea  
  • Drowsiness  
  • Nausea  
  • Dizziness  
  • Dry mouth  
  • Changes in appetite  


Is CBD oil legal in the USA?  

The answer to this question is a bit complicated. Hemp-derived CBD oil containing around 0.3% THC is legal to use on the federal level; however, states hold the right to regulate the use of CBD products. If the percentage of THC is higher than 0.3%, than it may be illegal in the state you live in, for both medicinal and recreational purposes.   


Another thing to remember is that the Food and Drug Administration (FDA) does not approve all CBD products available in the market. One of the only CBD based products approved by the FDA is Epidiolex, which is used to treat two severe forms of epilepsy. So before you set out to find CBD oil, be sure to check the rules about the legality of the product in your state.   



We hope that we have answered all your questions about CBD oil. There are a few things you may want to remember when using it. Before buying it or any other CBD product, be sure to see if an independent lab has tested the product, this way, you can be sure that you are not using any substandard CBD product, which may damage your health. Additionally, be sure to consult with a doctor before trying any CBD products, especially if you are taking any pharmaceutical drugs. CBD may interfere with the medication and can prevent it from working.
