The cbd oil It is made by extracting CBD from the cannabis plant and then diluting it with a carrier oil such as coconut or hemp seed oil.
It is gaining momentum in the world of health and wellness, with some scientific studies confirming that it can relieve symptoms of ailments such as chronic pain and anxiety.
Here there is seven health benefits of CBD oil that are backed by scientific evidence.
1. Pain relief
CBD, especially in combination with THC, can be effective in reducing pain associated with conditions such as multiple sclerosis and rheumatoid arthritis.
Marijuana has been used to treat pain since 2900 BC
More recently, scientists have discovered that certain components of marijuana, including CBD, are responsible for its pain-relieving effects.
The human body contains a specialized system called the endocannabinoid (ECS), which is involved in the regulation of a variety of functions including sleep, appetite, pain, and immune system response (3Trusted Source)
The body produces endocannabinoids, which are neurotransmitters that bind to cannabinoid receptors in your nervous system.
Studies have shown that CBD can help reduce chronic pain by affecting endocannabinoid receptor activity, reducing inflammation, and interacting with neurotransmitters.
For example, a study in rats found that CBD injections reduced the pain response to the surgical incisionwhile another study in rats found that oral CBD treatment significantly reduced sciatic nerve pain and inflammation.
Several human studies have found a combination of CBD and THC to be effective in treating pain related to multiple sclerosis and arthritis.
An oral spray called sativexwhich is a combination of THC and CBD, is approved in several countries to treat pain related to multiple sclerosis.
A study of 47 people with multiple sclerosis examined the effects of taking Sativex for one month. Participants experienced improvements in pain, gait, and muscle spasms. Still, the study did not include any control groups and placebo effects cannot be ruled out.
Another study found that Sativex significantly improved pain during movement, pain at rest, and quality of sleep in 58 people with rheumatoid arthritis.
2. Reduces anxiety and depression
- The use of CBD has been shown to reduce anxiety and depression in both human and animal studies.
Anxiety and depression are common mental health disorders that can have devastating effects on health and well-being.
According to World Health Organizationdepression is the largest contributor to disability worldwide, while anxiety disorders rank sixth.
Anxiety and depression are usually treated with pharmaceutical medications, which can cause a number of side effects including drowsiness, agitation, insomnia, sexual dysfunction, and headache.
Also, Medications such as benzodiazepines can be addictive and can lead to substance abuse.
CBD oil has shown promise as a treatment for both depression and anxiety, leading many people living with these disorders to take an interest in this natural approach.
In a Brazilian study, 57 men received oral CBD or a placebo 90 minutes before undergoing a simulated public speaking test. The researchers found that a 300mg dose of CBD was the most effective in significantly reducing anxiety during the test.
Placebo, a 150-mg dose of CBD, and a 600-mg dose of CBD had little or no effect on anxiety.
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 various animal studies.
These qualities are linked to CBD’s ability to act on brain receptors for serotonin, a neurotransmitter that regulates mood and social behavior.
3. Relieves Cancer-Related Symptoms
- Although 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.
CBD can help reduce cancer-related symptoms and side effects related to cancer treatment, such as nausea, vomiting, and pain.
One study looked at the effects of CBD and THC on 177 people with cancer-related pain who did not experience relief with pain medication.
Those treated with an extract containing both compounds experienced a significant reduction in pain compared to those given only THC extract.
CBD may also help reduce chemotherapy-induced nausea and vomiting, which are among the most common chemotherapy-related side effects for people with cancer.
Although there are medications that help with these distressing symptomsare sometimes ineffective, leading some people to look for alternatives.
A study of 16 people who underwent chemotherapy found that a single combination of CBD and THC delivered by spray reduced chemotherapy-related nausea and vomiting better than standard treatment alone.
Some test-tube and animal studies have even shown that CBD may have anti-cancer properties. For example, a test-tube study found that concentrated CBD-induced cell death in human breast cancer cells.
Another study showed that CBD inhibited the spread of aggressive breast cancer cells in mice.
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 drawn.
4. It can reduce acne
- CBD may have beneficial effects on acne due to its anti-inflammatory qualities and its ability to control excessive sebum production from the sebaceous glands.
Acne is a common skin condition that affects more than 9% of the population.
It is believed to be caused by a number of factors, such as genetics, bacteria, underlying inflammation, and overproduction of sebuman oily secretion produced by sebaceous glands in the skin.
According to recent scientific studies, CBD oil can help treat acne due to its anti-inflammatory properties and its ability to reduce sebum production.
A 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 such as inflammatory cytokines.
Another study had similar findings, concluding that CBD may be an efficient and safe way to treat acne, thanks in part to its remarkable anti-inflammatory qualities.
Although these results are promising, human studies exploring the effects of CBD on acne are needed.
5. It has beneficial properties at the neuronal level
- Although research is limited at this time, CBD has been shown to relieve 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.
Researchers believe that CBD’s ability to act on the endocannabinoid system and other brain signaling systems may provide benefits for people with neurological disorders.
In fact, one of the most studied uses for CBD is in the treatment of neurological disorders such as epilepsy and multiple sclerosis. Although research in this area is still relatively new, several studies have shown promising results.
the sativexan oral spray consisting of CBD and THC, has been shown 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 experienced drug-resistant muscle spasticity.
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 attacks were reduced by a median of 36.5%.
One more study found that CBD oil significantly reduced seizure activity in children with Dravet’s syndromea complex childhood epilepsy disorder, compared with a placebo.
However, it is important to note that some people in both studies experienced adverse reactions associated with CBD treatment, such as seizures, fever and fatigue.
CBD has also been investigated for its potential effectiveness in treating various other neurological diseases.
For example, several studies have shown that CBD treatment improved quality of life and quality of sleep for people with Parkinson’s disease.
Additionally, animal and test-tube studies have shown that CBD can decrease inflammation and help prevent neurodegeneration associated with Alzheimer’s disease.
In a long-term study, researchers administered CBD to mice genetically predisposed to Alzheimer’s disease and found that it helped prevent cognitive decline.
6. Benefits for the heart
- Although more human studies are needed, CBD may benefit heart health in several ways, including lowering blood pressure and preventing heart damage.
Recent research has linked CBD to various benefits for the heart and circulatory system, including the ability to lower high blood pressure.
High blood pressure is linked to an increased risk of a number of health conditions, including stroke, heart attack, and metabolic syndrome.
The studies indicate that CBD can help with high blood pressure.
A recent study treated nine healthy men with a 600mg dose of CBD oil and found that it lowered blood pressure at rest, compared to a placebo.
