The cannabis sativa plant produces cannabidiol (CBD) oil, which has drawn a lot of interest due to its possible medical uses. Since CBD is not intoxicating, it is a desirable alternative for those looking for treatment from a variety of medical issues without the “high” associated with tetrahydrocannabinol (THC), the psychoactive ingredient in cannabis. An important regulator of the endocannabinoid system (ECS), CBD affects immunological function, mood, inflammation, and pain, among other physiological processes. However, worries regarding safety and adverse consequences still exist, and its rising popularity has overtaken thorough scientific proof. In order to provide the general public precise, scientifically supported advice, this article examines ten evidence-based health advantages of CBD oil in addition to any possible negative effects. This article seeks to enable well-informed decision-making by discussing the therapeutic possibilities as well as the hazards.
Overview of CBD Oil
Hemp or cannabis plants are used to extract CBD oil, which is then diluted with a carrier oil like MCT or hemp seed oil. It interacts with the ECS, a system of endocannabinoids, enzymes, and CB1 and CB2 receptors that controls homeostasis. Whereas CB2 receptors are present in immune cells and peripheral organs, CB1 receptors are mostly prevalent in the brain and central nervous system. Because of its low affinity for these receptors, CBD differs from THC in that it acts indirectly via modulating 5-HT1A serotonin receptors, TRPV1 receptors, and endocannabinoid breakdown enzymes.
An important turning point was reached in 2018 when the FDA approved Epidiolex®, a CBD-based medication, for uncommon epilepsy conditions. However, questions about safety, effectiveness, and quality are raised by the widespread use of unregulated CBD products. In order to provide a fair viewpoint, this article analyzes the negative effects of CBD oil while outlining ten health advantages that are backed by scientific data.
Benefits of CBD Oil for Health
1. Epilepsy Seizures Are Reduced
The most well-known use of CBD oil is in the treatment of refractory epilepsy. Epidiolex is authorized for the treatment of tuberous sclerosis complex, Lennox-Gastaut syndrome, and Dravet syndrome. According to a 2018 research published in The New England Journal of Medicine, individuals with Dravet syndrome had 38.9% fewer convulsive seizures while using CBD, as opposed to 13.3% when using a placebo. Lennox-Gastaut syndrome showed similar outcomes, with a 41.9% decrease in drop seizures.
The anticonvulsant effects of CBD may include increased GABA signaling, suppression of adenosine reuptake, and modification of neuronal excitability via TRPV1 receptors. Because of these processes, CBD is a vital choice for people with epilepsy who are not responding to medication.
2. Pain Management for Chronic Conditions
Millions of people suffer from chronic pain, and CBD oil has potential as an analgesic. According to preclinical research, CBD lessens pain by desensitizing TRPV1 receptors, blocking pro-inflammatory cytokines, and activating CB2 receptors. There is strong evidence that cannabis may effectively treat chronic pain, especially neuropathic pain, according to a 2017 National Academies study.
Although findings for other pain types (such as arthritis and fibromyalgia) were less consistent, a 2020 meta-analysis published in Pain found that CBD was somewhat effective for neuropathic pain. To maximize results, standardized formulations and dosage are required.
3. Reduction of Anxiety
The anxiolytic properties of CBD oil have drawn interest in relation to disorders such as post-traumatic stress disorder (PTSD), social anxiety disorder (SAD), and generalized anxiety disorder (GAD). According to preclinical research, CBD inhibits anxiety-like behaviors via modulating the ECS and activating the 5-HT1A receptor. After using CBD for two months, 79.2% of patients with anxiety reported a reduction in their symptoms, according to a 2019 research published in The Permanente Journal. In SAD individuals, a single 600 mg dosage also decreased anxiety while speaking in front of an audience.
Although more extensive research is required, these results imply that CBD could provide an alternative to conventional anxiolytics.
4. Neuroprotection in Disorders of Degeneration
Because of its neuroprotective qualities, CBD may be useful in treating neurological diseases including multiple sclerosis (MS), Parkinson’s disease, and Alzheimer’s. In preclinical settings, it lowers neuronal apoptosis, oxidative stress, and neuroinflammation. In Alzheimer’s models, CBD reduced beta-amyloid-induced neurotoxicity, according to a 2020 research published in Molecules.
Although sparse, clinical data is encouraging. According to a 2021 research published in the Journal of Clinical Psychopharmacology, CBD helped Parkinson’s patients sleep better and had better motor function. A THC:CBD spray called Nabiximols is authorized in a number of nations to treat MS-related spasticity.
5. Reduction of Inflammation
Psoriasis, rheumatoid arthritis, and inflammatory bowel disease (IBD) may all benefit from CBD oil’s anti-inflammatory qualities. CBD balances the immune system by suppressing cytokines and encouraging regulatory T-cell activity. The immune-modulating properties of CBD were emphasized in a 2023 review published in Cannabis and Cannabinoid Research.
Larger trials are required to validate the effectiveness of CBD-enriched extracts, but a 2022 study in Pain Therapy revealed that they alleviated Crohn’s disease symptoms.
6. Enhancement of Sleep
CBD oil may help people sleep better, especially those who suffer from chronic pain or anxiety. After using CBD for a month, 66.7% of patients reported having improved sleep, according to a 2019 research published in The Permanente Journal. CBD may encourage relaxation and control sleep-wake cycles due to its anxiolytic properties and interaction with 5-HT1A receptors.
High dosages, however, may make you drowsy, and more research is needed to determine the long-term consequences on sleep architecture.
7. Assistance for Substance Abuse
Withdrawal symptoms and cravings in drug use disorders, especially opioid addiction, may be lessened by CBD oil. According to preclinical research, CBD interacts with the dopamine and opioid systems to modify reward pathways. According to a 2021 research published in Frontiers in Psychiatry, CBD helped heroin-abstinent people feel less anxious and tempted by cues.
Although clinical studies are still being conducted, these results imply that CBD may aid in the treatment of addiction.
8. Health of the Heart
According to new research, CBD oil may lower blood pressure and prevent vascular damage, therefore improving cardiovascular health. A single 600 mg dosage of CBD decreased resting blood pressure and stress-induced hypertension in healthy volunteers, according to a 2017 research published in JCI Insight. These advantages could be attributed to CBD’s anti-inflammatory and antioxidant properties.
More study is necessary, however, since there is a lack of information on long-term cardiovascular consequences.
9. Health of the Skin
Because of its anti-inflammatory and sebum-regulating qualities, CBD oil may be useful for treating psoriasis and acne. According to a 2014 research published in the Journal of Clinical Investigation, CBD reduced sebocyte inflammation and prevented the generation of sebum. Because topical CBD modulates immunological responses, it may help lessen the symptoms of psoriasis.
Although there are few clinical studies, anecdotal evidence suggests that CBD may have dermatological benefits.
10. Impact of Antipsychotics
CBD oil has shown potential in the treatment of psychotic symptoms, especially in schizophrenia. According to preclinical research, CBD lessens psychotic symptoms and alters dopamine signaling. In contrast to a placebo, CBD reduced positive psychotic symptoms in schizophrenia patients, according to a 2018 research published in the American Journal of Psychiatry.
These results suggest that CBD may be used in addition to antipsychotic drugs, although further study is required.
CBD Oil Side Effects
Despite being typically well accepted, there are certain hazards associated with CBD oil. The main adverse effects and safety issues are listed below.
1. Digestive Problems
Nausea, diarrhea, and decreased appetite are typical adverse effects. Usually dose-dependent, they go away when the dosage is changed. At larger dosages (≥300 mg/day), gastrointestinal side effects are more common, according to a 2024 review published in StatPearls.
2. Weariness and sluggishness
Especially when used in large quantities, CBD might make you feel sleepy or exhausted. Driving and other tasks requiring attentiveness may be hampered by this. Low dosages should be given to patients at first, and their reaction should be tracked.
3. Toxicology of the Liver
Liver enzymes may rise in response to high doses of CBD, suggesting possible hepatotoxicity. According to a 2024 research published in StatPearls, this risk necessitated routine liver function monitoring for Epidiolex patients. CBD should be used with caution by those who already have liver issues.
4. Interactions with Drugs
The cytochrome P450 enzymes (CYP3A4, CYP2C19) that metabolize a variety of drugs, such as antiepileptics, antidepressants, and anticoagulants, are inhibited by CBD. According to a 2021 review published in the Journal of General Internal Medicine, CBD raised warfarin levels, which increased the risk of bleeding. Before using CBD with other medications, speak with your doctor.
5. Mouth Dryness
Dry mouth may result from CBD’s ability to decrease saliva production. Hydration may help alleviate this typical adverse effect of cannabis.
6. Shifts in Mood
Especially when taking large amounts, some users report feeling irritated or experiencing mood swings. Although less frequent, these side effects are nonetheless worth keeping an eye on, particularly in individuals who have mental health issues.
7. Dependency Possibility
Products containing tiny amounts of THC (≤0.3%) may have a minimal risk of psychological dependency with long-term usage, even though CBD does not have the same reinforcing effects as THC. Concerns over regular usage were raised by a 2023 research published in the Journal of Medical Internet Research, which observed patterns in self-medication.
8. Impact of Hormones
Although there is little research, CBD may have an impact on hormone levels, especially those of cortisol and thyroid hormones. According to preclinical research, CBD alters the hypothalamic-pituitary-adrenal axis, which may have an effect on stress reactions.
9. Reactions to Allergies
Rarely, especially in those who are sensitive to cannabis or carrier oils, CBD oil may result in allergic responses such skin rashes or respiratory problems. Patch testing is advised when using topical medications.
10. Uncontrolled Product Hazards
The quality of the products varies due to the absence of FDA regulation. According to a 2022 research published in the Journal of Cannabis Research, several CBD oils were mislabeled, and some of them included pollutants or THC. To guarantee safety, third-party testing is necessary.
Safety and Regulatory Aspects
The FDA forbids its use in food or dietary supplements without further testing, despite the 2018 Farm Bill legalizing hemp-derived CBD with ≤0.3% THC in the US. Customers are at danger as a result of the deluge of unregulated items brought about by this regulatory void. Regulations differ throughout the world; some nations allow CBD drugs, while others prohibit all goods produced from cannabis.
Customers have to choose goods whose third-party lab tests confirm the amount of THC, CBD, and pollutants present. Healthcare professionals should advise patients with comorbidities or polypharmacy on dosage and keep an eye out for adverse effects.
In conclusion
According to an increasing amount of scientific research, CBD oil has great medicinal promise for ailments including epilepsy, chronic pain, anxiety, and neurodegenerative diseases. Because of its anxiolytic, neuroprotective, and anti-inflammatory qualities, it is a flexible option for a range of medical uses. However, adverse consequences such gastrointestinal problems, medication interactions, and liver damage emphasize the need for vigilance. The significance of informed usage is further highlighted by the absence of regulation and the possibility of reliance with uncontrolled products. Customers may minimize hazards and optimize the advantages of CBD oil by selecting high-quality products and seeking advice from medical specialists. To fully realize its medicinal potential, more rigorous restrictions and ongoing study are essential.
