Cannabidiol is a popular natural remedy used for many common ailments. Here are some health benefits of CBD oil that are backed by scientific evidence.
1. Can Relieve Pain
Marijuana has been used to treat pain as far back as 2900 B.C. More recently, scientists have discovered that certain components of marijuana, including CBD, are responsible for its pain-relieving effects.
Studies have shown that CBD may help reduce chronic pain by impacting endocannabinoid receptor activity, reducing inflammation and interacting with neurotransmitters.
For example, one study in rats found that CBD injections reduced pain response to surgical incision, while another rat study found that oral CBD treatment significantly reduced sciatic nerve pain and inflammation.
Several human studies have found that a combination of CBD and THC is effective in treating pain related to multiple sclerosis and arthritis.
2. Could Reduce Anxiety and Depression
Anxiety and depression are common mental health disorders that can have devastating impacts on health and well-being.According to the World Health Organization, depression is the single largest contributor to disability worldwide, while anxiety disorders are ranked sixth.CBD oil has shown promise as a treatment for both depression and anxiety, leading many who live with these disorders to become interested in this natural approach.
In one Brazilian study, 57 men received either oral CBD or a placebo 90 minutes before they underwent a simulated public speaking test. The researchers found that a 300-mg dose of CBD was the most effective at significantly reducing anxiety during the test.CBD oil has even been used to safely treat insomnia and anxiety in children with post-traumatic stress disorder.CBD has also shown antidepressant-like effects in several animal studies.
3. Can Alleviate Cancer-Related Symptoms
CBD may help reduce symptoms related to cancer and side effects related to cancer treatment, like nausea, vomiting and pain.
Some test-tube and animal studies have even shown that CBD may have anticancer properties. For example, one test-tube study found that concentrated CBD induced cell death in human breast cancer cells.
Though CBD has been shown to help reduce symptoms related to cancer and cancer treatment, and may even have cancer-fighting properties, more research is needed to assess its efficacy and safety.
4. May Reduce Acne
Acne is a common skin condition that affects more than 9% of the population.
One test-tube study found that CBD oil prevented sebaceous gland cells from secreting excessive sebum, exerted anti-inflammatory actions and prevented the activation of “pro-acne” agents like inflammatory cytokines.
CBD may have beneficial effects on acne due to its anti-inflammatory qualities and its ability to control the overproduction of sebum from the sebaceous glands.
5. Might Have Neuroprotective Properties
One study gave 214 people with severe epilepsy 0.9–2.3 grams of CBD oil per pound (2–5 g/kg) of body weight. Their seizures reduced by a median of 36.5%.
Though research is limited at this time, CBD has been shown to ease symptoms related to epilepsy and Parkinson’s disease. CBD was also shown to reduce the progression of Alzheimer’s disease in test-tube and animal studies.
6. Could Benefit Heart Health
Recent research has linked CBD with several benefits for the heart and circulatory system, including the ability to lower high blood pressure.
High blood pressure is linked to higher risks of a number of health conditions, including stroke, heart attack and metabolic syndrome.
Several animal studies have demonstrated that CBD may help reduce the inflammation and cell death associated with heart disease due to its powerful antioxidant and stress-reducing properties.
Though more human studies are needed, CBD may benefit heart health in several ways, including by reducing blood pressure and preventing heart damage.
7. Several Other Potential Benefits
Though more studies are needed, CBD is thought to provide the following health benefits:
Antipsychotic effects: Studies suggest that CBD may help people with schizophrenia and other mental disorders by reducing psychotic symptoms.
Substance abuse treatment: CBD has been shown to modify circuits in the brain related to drug addiction. In rats, CBD has been shown to reduce morphine dependence and heroin-seeking behavior.
Anti-tumor effects: In test-tube and animal studies, CBD has demonstrated anti-tumor effects. In animals, it has been shown to prevent the spread of breast, prostate, brain, colon and lung cancer.
Diabetes prevention: In diabetic mice, treatment with CBD reduced the incidence of diabetes by 56% and significantly reduced inflammation
