Here are seven health benefits of CBD oil that are backed by scientific evidence.

 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.

Anxiety and depression are usually treated

with pharmaceutical drugs, which can cause a number of side effects

including drowsiness, agitation, insomnia, sexual dysfunction and headache (10Trusted Source).

What’s more, medications like benzodiazepines

can be addictive and may lead to substance abuse (11Trusted Source).

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 study, 24 people with social anxiety disorder received either 600 mg of CBD

or a placebo before a public speaking test.

The group that received the CBD had significantly less anxiety,

cognitive impairment and discomfort in their speech performance,

compared to the placebo group (12Trusted Source).

CBD oil has even been used to safely treat insomnia and anxiety in children

with post-traumatic stress disorder (13Trusted Source).

CBD has also shown antidepressant-like effects in several animal studies (14Trusted Source15Trusted Source).

These qualities are linked to CBD’s ability to act on the brain’s receptors for serotonin,

a neurotransmitter that regulates mood and social behavior.

 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.

One study looked at the effects of CBD and THC in 177 people with cancer-related pain

who did not experience relief from pain medication.

Those treated with an extract containing both compounds

experienced a significant reduction in pain

compared to those who received only THC extract (16Trusted Source).

CBD may also help reduce chemotherapy-induced nausea and vomiting,

which are among the most common chemotherapy-related side effects

for those with cancer (17Trusted Source).

Though there are drugs that help with these distressing symptoms,

they are sometimes ineffective, leading some people to seek alternatives.

A study of 16 people undergoing chemotherapy

foundthat a one-to-one combination of CBD and THC administered via mouth spray

reduced chemotherapy-related nausea and vomiting

better than standard treatment alone (18Trusted Source).

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 (19Trusted Source).

Another study showed that CBD

inhibited the spread of aggressive breast cancer cells in mice (20Trusted Source).

However, these are test-tube and animal studies, so they can only suggest what might work in people.

More studies in humans are needed before conclusions can be made.

Cannabidiol oil. Might Have Neuroprotective Properties

Researchers believe that CBD’s ability to act on the endocannabinoid system

and other brain signaling systems

may provide benefits for those with neurological disorders.

In fact, one of the most studied uses for CBD is in treating neurological disorders

like epilepsy and multiple sclerosis.

Though research in this area is still relatively new,

several studies have shown promising results.

Sativex, an oral spray consisting of CBD and THC,

has been proven to be a safe and effective way

to reduce muscle spasticity in people with multiple sclerosis.

One study found that Sativex reduced spasms in 75% of 276 people with multiple sclerosis

who were experiencing muscle spasticity that was resistant to medications (26Trusted Source).

Another 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% (27Trusted Source).

Cannabidiol oil

One more study found that CBD oil significantly reduced seizure activity in children with Dravet syndrome,

a complex childhood epilepsy disorder, compared to a placebo (28Trusted Source).

However, it’s important to note that some people in both these studies

experienced adverse reactions associated with CBD treatment, such as convulsions, fever and diarrhea.

CBD has also been researched for its potential effectiveness in treating several other neurological diseases.

For example, several studies have shown that treatment with CBD.

improved quality of life and sleep quality

for people with Parkinson’s disease (29Trusted Source30Trusted Source).

Additionally, animal and test-tube studies

have shown that CBD may decrease inflammation

and help prevent the neurodegeneration

associated with Alzheimer’s disease (31Trusted Source).

In one long-term study, researchers gave CBD to mice genetically predisposed to Alzheimer’s disease,

finding that it helped prevent cognitive decline (32Trusted Source).

CBD was also shown to reduce the progression of Alzheimer’s disease in test-tube and animal studies.

 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 (33Trusted Source).

Studies indicate that CBD may be a natural and effective treatment for high blood pressure.

One recent study treated 10 healthy men with one dose of 600 mg of CBD oil

and found it reduced resting blood pressure, compared to a placebo.

The same study also gave the men stress tests

that normally increase blood pressure.

Interestingly, the single dose of CBD

led the men to experience a smaller blood pressure increase than normal

in response to these tests (34Trusted Source).

Researchers have suggested that the stress

 and anxiety-reducing properties of CBD

are responsible for its ability to help lower blood pressure.

Additionally, 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.

For example, one study found that treatment with CBD reduced oxidative stress

and prevented heart damage in diabetic mice with heart disease (35Trusted Source).

 Several Other Potential Benefits

CBD has been studied for its role in treating a number of health issues other than those outlined above.

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 (36Trusted Source).
  • 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 (37Trusted Source).
  • 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 (38Trusted Source).
  • Diabetes prevention: In diabetic mice, treatment with CBD
  • reduced the incidence of diabetes by 56%
  • and significantly reduced inflammation (39Trusted Source).

Some studies suggest that  may be an effective treatment for diabetes,

substance abuse, mental disorders and certain types of cancers.

However, more research in humans is needed.

Are There Any Side Effects?

Though CBD is generally well tolerated and considered safe, it may cause adverse reactions in some people.

Side effects noted in studies include (40Trusted Source):

  • Diarrhea
  • Changes in appetite
  • Fatigue

CBD is also known to interact with several medications.

Before you start using CBD oil, discuss it with your doctor to ensure your safety

and avoid potentially harmful interactions (41Trusted Source).

Cannabidiol oil. The Bottom Line

CBD oil has been studied for its potential role in treating many common health issues,

including anxiety, depression, acne and heart disease.

For those with cancer, it may even provide a natural alternative for pain and symptom relief.

Research on the potential health benefits of Cannabidiol oil

is ongoing, so new therapeutic uses for this natural remedy are sure to be discovered.

Though there is much to be learned about the efficacy and safety of Cannabidiol oil,

results from recent studies suggest that Cannabidiol oil may provide a safe, powerful natural treatment

for many health issues.

Does  CBD make you high?

CBD is an entirely different compound from THC,

and its effects are very complex.

It is not psychoactive, meaning it does not produce a “high” or change a person’s state of mind, 

but it influences the body to use its own endocannabinoids more effectively.

According to one study posted to Neurotherapeutics, this is because CBD itself does very little to the ECS.

Instead, it activates or inhibits other compounds in the endocannabinoid system.

For example, Cannabidiol oil stops the body

from absorbing anandamide, a compound associated with regulating pain.

So, increased levels of anandamide in the bloodstream

may reduce the amount of pain a person feels.

Cannabidiol may also limit inflammation

in the brain and nervous system,

which may benefit people experiencing pain,

insomnia, and certain immune-system responses.
