Some forms of CBD oil can also be applied directly to the skin, in the form of CBD oil may be of some benefit to those with addiction, suggests a review. Only one purported use for cannabidiol, to treat epilepsy, has about both the quality of CBD oil being produced and its potential side effects. Learn how the benefits of hemp oil changed their lives and find out how it give you the information you need, straight from the people who regularly use it.
uses reviews benefits oil and cbd
Many studies have found that CBD can reduce joint inflammation and other inflammatory pain in rats, without side effects. This may point to potential relief from arthritis in humans 3.
In fact, one of the first trials of Sativex, a medicine that contains both CBD and THC, reported significant improvement in pain and sleep quality in 58 rheumatoid arthritis patients 4. The same medicine showed a notable reduction in pain and muscle spasms in a small group of people with Multiple Sclerosis.
Analyzing several trials and studies, a report concluded that adults treated with cannabis or cannabinoids, like CBD, are likely to experience a significant reduction in chronic pain symptoms 5. There is some indication that CBD oil could help treat anxiety and depression. In various animal studies, CBD has shown notable anti-anxiety and antidepressant-like effects 6 , 7 , 8.
With a group of 60 people, they found that CBD showed anti-anxiety effects, but only in specific doses. A case study on a child with post-traumatic stress disorder found that CBD oil helped safely reduce her anxiety and improve her sleep However, they did see some positive effects for those with social anxiety disorder There are some other dietary components thought to influence depression here.
While they emphasize that CBD is not a cure, plenty of research shows it can be highly beneficial in inhibiting the progression of many types of cancer, including breast, lung, prostate and colon cancer CBD is also effective in lowering cancer-related pain, as well as nausea and vomiting caused by chemotherapy.
Much of the research on CBD has looked at its seizure-reducing effects on two rare forms of childhood-onset epilepsy, Lennox-Gastaut syndrome and Dravet syndrome. In fact, the FDA just approved the first prescription cannabis drug, called Epidiolex, for these two forms of epilepsy Interestingly, CBD actually counteracts the psychoactive properties of THC, meaning it may help those addicted to marijuana. Some scientists also believe that CBD could have the potential to help treat type 2 diabetes and cardiovascular disease because of its anti-inflammatory properties.
It did appear to lower the incidence of diabetes in mice In fact, it may be more effective than vitamin C and E in improving skin conditions Early research has found that CBD oil has the potential to reduce chronic pain, anxiety, depression and acne, and may help those overcoming addiction. Its anti-inflammatory properties may also play a role in lowering the risk of diabetes and cardiovascular disease. A similar effect was previously described in anxiety experiments, where CBD proved to be only anxiolytic in subjects where stress had been induced before CBD administration.
Elevated glutamate levels have been proposed to be responsible for ketamine's fast antidepressant function and its dysregulation has been described in OBX mice and depressed patients.
Chronic CBD treatment did not elicit behavioral changes in the nonoperated mice. No adverse effects were reported in this study. Various studies on CBD and psychosis have been conducted. The two higher CBD doses had beneficial effects comparable to the atypical antipsychotic drug clozapine and also attenuated the MK effects on the three markers mentioned above.
The publication did not record any side effects. One of the theories trying to explain the etiology of bipolar disorder BD is that oxidative stress is crucial in its development.
Whereas CBD did not have an effect on locomotion, it did increase brain-derived neurotrophic factor BDNF levels and could protect against amphetamine-induced oxidative damage in proteins of the hippocampus and striatum. No adverse effects were recorded in this study. Another model for BD and schizophrenia is PPI of the startle reflex both in humans and animals, which is disrupted in these diseases.
CBD, which is nonhedonic, can reduce heroin-seeking behavior after, for example, cue-induced reinstatement. In addition, the described study was able to replicate previous findings showing no CBD side effects on locomotor behavior. There are various mechanisms underlying neuroprotection, for example, energy metabolism whose alteration has been implied in several psychiatric disorders and proper mitochondrial functioning.
A study comparing acute and chronic CBD administration in rats suggests an additional mechanism of CBD neuroprotection: Mitochondrial activity was measured in the striatum, hippocampus, and the prefrontal cortex. Since the mitochondrial complexes I and II have been implied in various neurodegenerative diseases and also altered ROS reactive oxygen species levels, which have also been shown to be altered by CBD, this might be an additional mechanism of CBD-mediated neuroprotection.
In healthy cells, this can be interpreted as a way to protect against the higher ROS levels resulting from more mitochondrial activity. Another publication studied the difference of acute and chronic administration of two doses of CBD in nonstressed mice on anxiety.
Already an acute i. Fifteen days of repeated i. However, the higher dose caused a decrease in neurogenesis and cell proliferation, indicating dissociation of behavioral and proliferative effects of chronic CBD treatment. The study does not mention adverse effects. Numerous studies show the CBD immunomodulatory role in various diseases such as multiple sclerosis, arthritis, and diabetes.
These animal and human ex vivo studies have been reviewed extensively elsewhere, but studies with pure CBD are still lacking. It would be especially interesting to study when CBD is proinflammatory and under which circumstances it is anti-inflammatory and whether this leads to side effects Burstein, Table 1 shows a summary of its anti-inflammatory actions; McAllister et al.
In case of Alzheimer's disease AD , studies in mice and rats showed reduced amyloid beta neuroinflammation linked to reduced interleukin [IL]-6 and microglial activation after CBD treatment. This led to amelioration of learning effects in a pharmacological model of AD. The chronic study we want to describe in more detail here used a transgenic mouse model of AD, where 2. CBD was able to prevent the development of a social recognition deficit in the AD transgenic mice.
Using statistical analysis by analysis of variance, this was shown to be only a trend. This might have been caused by the high variation in the transgenic mouse group, though.
This was probably due to already elevated cholesterol in the transgenic mice. The study observed no side effects. After CBD treatment was stopped, observation continued until the mice were 24 weeks old. CBD increased IL levels, which is thought to act as an anti-inflammatory cytokine in this context.
After inducing arthritis in rats using Freund's adjuvant, various CBD doses 0. CBD reduced joint swelling, immune cell infiltration. CBD was shown to be able to influence migratory behavior in cancer, which is also an important aspect of embryogenesis. Helix-loop-helix Id proteins play a role in embryogenesis and normal development via regulation of cell differentiation.
High Id1-levels were also found in breast, prostate, brain, and head and neck tumor cells, which were highly aggressive. In contrast, Id1 expression was low in noninvasive tumor cells. Id1 seems to influence the tumor cell phenotype by regulation of invasion, epithelial to mesenchymal transition, angiogenesis, and cell proliferation.
There only seems to exist one study that could not show an adverse CBD effect on embryogenesis. An in vitro study could show that the development of two-cell embryos was not arrested at CBD concentrations of 6. Various studies have been performed to study CBD anticancer effects. CBD every 3 days for a total of 28 weeks, almost completely reduced the development of metastatic nodules caused by injection of human lung carcinoma cells A in nude mice.
The typical side effects of traditional anticancer medication, emesis, and collateral toxicity were not described in these studies. Consequently, CBD could be an alternative to other MMP1 inhibitors such as marimastat and prinomastat, which have shown disappointing clinical results due to these drugs' adverse muscoskeletal effects. Two studies showed in various cell lines and in tumor-bearing mice that CBD was able to reduce tumor metastasis.
CBD downregulated Id1 at promoter level and reduced tumor aggressiveness. Moreover, to carry out these experiments, animals are often immunologically compromised, to avoid immunogenic reactions as a result to implantation of human cells into the animals, which in turn can also affect the results.
Another approach was chosen by Aviello et al. After 3 months, the number of aberrant crypt foci, polyps, and tumors was analyzed. The high CBD concentration led to a significant decrease in polyps and a return to near-normal levels of phosphorylated Akt elevation caused by the carcinogen. Animal studies summarized by Bergamaschi et al.
Chronic administration 14 days, 2. This effect could be inhibited by coadministration of a CB2R antagonist. The positive effects of CBD on hyperglycemia seem to be mainly mediated via CBD anti-inflammatory and antioxidant effects.
In addition, treatment increased adiponectin and liver glycogen concentrations. CBD showed inhibition of testosterone oxidation in the liver. Motor function was also tested on a rotarod, which was also not affected by CBD administration. Static beam performance, as an indicator of sensorimotor coordination, showed more footslips in the CBD group, but CBD treatment did not interfere with the animals' speed and ability to complete the test. Compared to other anticonvulsant drugs, this effect was minimal.
CBD did not lead to adverse effects. In addition, psychomotor function and psychological functions were not disturbed. Interestingly, the CYP2C19 inhibitor omeprazole, used to treat gastroesophageal reflux, could not significantly affect the pharmacokinetics of CBD. Unfortunately, it was not mentioned whether this effect was mediated via the cytochrome P complex. Another aspect, which has not been thoroughly looked at, to our knowledge, is that several cytochrome isozymes are not only expressed in the liver but also in the brain.
It might be interesting to research organ-specific differences in the level of CBD inhibition of various isozymes. Apart from altering the bioavailability in the overall plasma of the patient, this interaction might alter therapeutic outcomes on another level.
Generally, more human studies, which monitor CBD-drug interactions, are needed. In a double-blind, placebo-controlled crossover study, CBD was coadministered with intravenous fentanyl to a total of 17 subjects. This was followed by a single 0. This extensive tool tests, for example, 78 adverse effects divided into 23 categories corresponding to organ systems or body parts.
No respiratory depression or cardiovascular complications were recorded during any test session. The results of the evaluation of pharmacokinetics, to see if interaction between the drugs occurred, were as follows. No effect was evident for urinary CBD and metabolite excretion except at the higher fentanyl dose, in which CBD clearance was reduced. Importantly, fentanyl coadministration did not produce respiratory depression or cardiovascular complications during the test sessions and CBD did not potentiate fentanyl's effects.
No correlation was found between CBD dose and plasma cortisol levels. CBD did not worsen the adverse effects e. Coadministration was safe and well tolerated, paving the way to use CBD as a potential treatment for opioid addiction. A Dutch study compared subjective adverse effects of three different strains of medicinal cannabis, distributed via pharmacies, using VAS.
The 12 adjectives used for this study were as follows: This strain showed significantly lower levels of anxiety and dejection. Moreover, appetite increased less in the high CBD strain.
The review by Bergamaschi et al. This holds especially true for the extrapyramidal motor side effects elicited by classical antipsychotic medication.
Order of drug administration was pseudorandomized across subjects, so that an equal number of subjects received any of the drugs during the first, second, or third session in a double-blind, repeated-measures, within-subject design.
This effect was caused by opposite neural activation of relevant brain areas. In addition, no effects on peripheral cardiovascular measures such as heart rate and blood pressure were measured. A randomized, double-blind, crossover, placebo-controlled trial was conducted in 16 healthy nonanxious subjects using a within-subject design. The doses were selected to only evoke neurocognitive effects without causing severe toxic, physical, or psychiatric reactions. The physiological parameters, heart rate and blood pressure, were also monitored and no significant difference between the placebo and the CBD group was observed.
A case study describes a patient treated for cannabis withdrawal according to the following CBD regimen: Hepatic enzymes were also measured daily, but no effect was reported. Naturalistic studies with smokers inhaling cannabis with varying amounts of CBD showed that the CBD levels were not altering psychomimetic symptoms. CBD might work to alleviate disorders of addiction, by altering the attentive salience of drug cues. The study did not further measure side effects. CBD can also reduce heroin-seeking behaviors e.
This was shown in the preclinical data mentioned earlier and was also replicated in a small double-blind pilot study with individuals addicted to opioids, who have been abstinent for 7 days.
One hour after the video session, subjective craving was already reduced after a single CBD administration. The effect persisted for 7 days after the last CBD treatment. Interestingly, anxiety measures were also reduced after treatment, whereas no adverse effects were described.
A pilot study with 24 subjects was conducted in a randomized, double-blind, placebo-controlled design to evaluate the impact of the ad hoc use of CBD in smokers, who wished to stop smoking. Pre- and post-testing for mood and craving of the participants was executed.
Craving was assessed using the Tiffany Craving Questionnaire On day 1 and 7, exhaled CO was measured to test smoking status. Sedation, depression, and anxiety were evaluated with the MRS.
At day 7, the anxiety levels for placebo and CBD group did not differ. CBD did not increase depression in contrast to the selective CB1 antagonist rimonabant. CBD might weaken the attentional bias to smoking cues or could have disrupted reconsolidation, thereby destabilizing drug-related memories.
To the best of our knowledge, no acute studies were performed that solely concentrated on CBD glycemic effects. Moreover, the only acute study that also measured CBD effect on appetite was the study we described above, comparing different cannabis strains.
Growth hormone and prolactin levels were unchanged. Compared to the healthy individuals, the cortisol levels increased less after TSST in the 32 at-risk individuals.
The CBD group showed less reduced cortisol levels but differences were not significant. Drops are the classic way to buy and administer CBD. Using a high quality, consistently dosed product you can easily manage consumption, and increase or decrease dosage as desired. These capsules again allow you to choose the exact dose, the dose usually being around mg per capsule. By choosing a capsule you avoid problems with the taste of hemp oil, and it allows the dose to be delivered the stomach to be fully absorbed there.
In salve form CBD is less filtered and processed. This may have additional health benefits. CBD salve is usually used for pain relief and psoriasis. Suppositories have the benefits of allowing you to administer a controlled dose, while also addressing absorption issues in the body because the colon absorbs absences very quickly and thoroughly. In whatever format you are looking to buy it, getting the best hemp oil for your money is essential. On top of that, you need to know that you are getting high quality product at a consistent dose.
Surprisingly, very few online retailers match these basic standards for consistency and quality of supply chain. So if you are looking for some reliable advice on where to buy CBD oil, then these highly recommended sellers are a good place to start. PlusCBDoil offers some incredibly high quality hemp oil for sale. Overall, if you are looking for the best quality, price, delivery and customer service they are difficult to beat.
Our second recommended CBD hemp oil seller is endoca, where you can buy a good range of high quality CBD hemp oil products:. Only Endoca sells mg CBD hemp oil! Our third recommended CBD hemp oil seller beyondbotanicals. One thing that is slightly confusing and possibly misleading is that they describe selling CBD oil tinctures.
Apart from that, they offer very high quality CBD hemp oil in various formats. They only use American industrial hemp which means that they can control the quality and produce a very refined product but also offers high concentration of CBD. We will be happy to hear your thoughts.
