Cannabidiol (CBD) oil is a product that’s derived from cannabis. It’s a type of cannabinoid, which are the chemicals naturally found in marijuana plants. Even though it comes from marijuana plants, CBD doesn’t create a “high” effect or any form of intoxication — that’s caused by another cannabinoid, known as THC.
There’s some controversy around cannabis products like CBD oil because of recreational marijuana use. But there’s growing awareness about the possible health benefits of CBD oil. Here’s what you need to know about six potential medical uses of CBD and where the research stands:
What is CBD oil?
Cannabidiol (CBD) is a cannabinoid – a chemical compound that acts throughout the body, including on certain parts of the brain, and is becoming increasingly popular in the health world. It comes from the cannabis plant; however, unlike its counterpart, tetrahydrocannabinol (THC), which is responsible for the ‘high’ from marijuana, CBD, derived from the hemp plant, is non-intoxicating and some believe it may have potential health and wellness benefits. Once extracted from the cannabis plant, it is diluted with a carrier such as olive or coconut oil – this improves its bioavailability.
What is CBD oil used for?
Supporters of CBD oil believe it may help a number of clinical conditions, including refractory epilepsy, chronic pain, depression, anxiety and acne. However, further robust evidence is required as much of the research is carried out on animal models.
A systematic review looking at the use of CBD for epilepsy concluded that there is insufficient evidence to support the efficacy and long-term safety of using it to treat epilepsy. It does, however, suggest, albeit in very low numbers, that small daily doses were safe in a small group of adults for a short period of time.
There are some suggestions from animal studies that CBD may be beneficial for osteoarthritis, through topical application for inflammation or joint pain.
One study reported reduced pain and muscle spasms in people with multiple sclerosis.
Early evidence looking into the use of CBD in the treatment of anxiety and depression has found some exciting results – although on very small samples. The first study assessed anxiety links with public speaking; it found a very specific dose of CBD (300mg) showed anti-anxiety effects. The second study was a stand-alone case report of one child with post-traumatic stress disorder (PTSD). It found CBD oil helped the child safely reduce her anxiety and improve sleep.
CBD may also have the potential to help reduce acne; however, it is important to note that this research is still in its infancy.
For all the above uses of CBD, more human studies are needed to draw conclusive results.
Is it safe to use CBD oil?
If you’re considering using CBD oil, you should speak to your GP or other healthcare professional to ensure that it is safe and appropriate for you to do so.
This is particularly important if you are experiencing any concerning symptoms, if you have any pre-existing conditions or if you are taking any medication including statins, blood thinning medication and calcium channel blockers.
Although the use of CBD is controversial, it does seem to be tolerated by most people. It has, however, caused hypotension and light-headedness in a small number of patients. As it does not contain the THC part of the cannabis plant, the oil will not induce a ‘high’.
6 Benefits of CBD Oil
1. Anxiety relief
CBD may be able to help you manage anxiety. Researchers thinkTrusted Source it may change the way your brain’s receptors respond to serotonin, a chemical linked to mental health. Receptors are tiny proteins attached to your cells that receive chemical messages and help your cells respond to different stimuli.
One studyTrusted Source found that a 600mg dose of CBD helped people with social anxiety give a speech. Other early studiesTrusted Source done with animals have shown that CBD may help relieve anxiety by:
- reducing stress
- decreasing physiological effects of anxiety, such as an increased heart rate
- improving symptoms of post-traumatic stress disorder (PTSD)
- inducing sleep in cases of insomnia
CBD has been in the news before, as a possible treatment for epilepsy. Research is still in its early days. Researchers are testing how much CBD is able to reduce the number of seizures in people with epilepsy, as well as how safe it is. The American Epilepsy Society states that cannabidiol research offers hope for seizure disorders, and that research is currently being conducted to better understand safe use.
A studyTrusted Source from 2016 worked with 214 people with epilepsy. The study participants added oral doses of 2 to 5mg of CBD per day to their existing anti-epilepsy medications. The study’s researchers monitored the participants for 12 weeks, recording any negative side effects and checking on the frequency of their seizures. Overall, participants had 36.5 percent fewer seizures per month. However, severe adverse effects were recorded in 12 percent of the participants.
Researchers are looking at a receptor located in the brain to learn about the ways that CBD could help people with neurodegenerative disorders, which are diseases that cause the brain and nerves to deteriorate over time. This receptor is known as CB1.
Researchers are studyingTrusted Source the use of CBD oil for treating:
- Alzheimer’s disease
- multiple sclerosis (MS)
- Parkinson’s disease
CBD oil may also reduce the inflammation that can make neurodegenerative symptoms worse. More research is needed to fully understand the effects of CBD oil for neurodegenerative diseases.
4. Pain relief
The effects of CBD oil on your brain’s receptors may also help you manage pain. Studies have shown that cannabis can offer some benefits when taken after chemotherapy treatments. Other pre-clinical studies sponsored by the National Institutes of HealthTrusted Source are also looking at the role of cannabis in relieving symptoms caused by:
- chronic pain
- MS pain
- muscle pain
- spinal cord injuries
Nabiximols (Sativex), a multiple sclerosis drug made from a combination of TCH and CBD, is approved in the United Kingdom and Canada to treat MS pain. However, researchers think the CBD in the drug may be contributing more with its anti-inflammatory properties than by acting against the pain. Clinical trials of CBD are necessary to determine whether or not it should be used for pain management.
The effects of CBD on receptors in the immune system may help reduce overall inflammation in the body. In turn, CBD oil may offer benefits for acne management. A human study published in the Journal of Clinical Investigation Found that the oil prevented activity in sebaceous glands. These glands are responsible for producing sebum, a natural oily substance that hydrates the skin. Too much sebum, however, can lead to acne.
Before you consider CBD oil for acne treatment, it’s worth discussing with your dermatologist. More human studies are needed to evaluate the potential benefits of CBD for acne.
6. Cancer treatment
Some studies have investigated the role of CBD in preventing cancer cell growth, but research is still in its early stages. The National Cancer InstituteTrusted Source (NCI) says that CBD may help alleviate cancer symptoms and cancer treatment side effects. However, the NCI doesn’t fully endorse any form of cannabis as a cancer treatment. The action of CBD that’s promising for cancer treatment is its ability to moderate inflammation and change how cell reproduce. CBD has the effect of reducing the ability of some types of tumor cells to reproduce.
