What kind of abrupt movements can CBD oil reduce — and what’s the secret behind its therapeutic versatility? This article breaks down the benefits of CBD for tremors. Tremors are caused by conditions, such as neurodegenerative diseases, anxiety, and brain injury. Can CBD help with tremors, if so, how?
Essential Tremor & CBD Oil: A Landmark Clinical Trial & Buying Tips
Cannabidiol (CBD) oil is well known for helping people with conditions that feature tremors as one of their symptoms, such as Parkinson’s disease. But there is one condition that has been largely overlooked—until now.
It may not be a life-threatening condition, but essential tremor (ET) affects a large proportion of the population. The exact number of sufferers is difficult to pinpoint, but reports estimate 2.2%–3% of Americans have ET, making it at least eight times more prevalent than Parkinson’s.
What Is Essential Tremor?
Essential tremor is characterized by involuntary shaking of body parts, but is not associated with Parkinson’s disease. Most often ET will manifest as shaking of the hands when performing manual tasks, such as tying your shoes or drinking from a glass. Essential tremor can also affect the head, voice, and legs.
One of the issues with finding an effective treatment for ET is that its origins are not well understood. There is thought to be an element of genetic predisposition, with 50% of essential tremor sufferers having inherited it from a parent. However, where the hereditary trait lies within the genes, and how it manifests itself is still a mystery.
There is no specific test which can be used to diagnose essential tremor, so a diagnosis is based on a review of the reported symptoms which can often be confused for Parkinson’s disease. Because of this, there is no cure, nor any preventative treatment available for ET, leading many to self-treat with more natural products like CBD oil.
How CBD Oil Can Help Essential Tremor
At this point in time, all that is currently known about CBD oil and ET is based on anecdotal evidence. Some people report having improved symptoms when using cannabis or CBD oil, with the frequency and intensity of their tremors noticeably reduced.
This prompted a team at the University of California, San Diego (UCSD) to undertake a targeted study on the use of CBD oil to help ET. The trial took place in 2019 and aimed to understand whether cannabinoids such as CBD can be used in a medical setting to provide relief to people who suffer from essential tremor.
Based on other research that has been conducted on similar conditions, CBD may possess the therapeutic properties that ET patients seek.
CBD Oil for Muscle Spasticity
The effects that CBD oil has on reducing muscle spasticity have been widely reported and accepted. Recently, CBD oil was approved as a medical treatment for spasms related to multiple sclerosis (MS) under the brand name Sativex in places like the U.K. and Canada.
Muscles contract when chemical messengers are sent to muscle tissue by the central nervous system. If an excess amount of these messengers are released and flood the muscle tissue, the area is forced to continuously contract, leading to twitching, tremors, and tightness. CBD oil has been shown to restrain the release of these messengers, allowing the muscles to relax.
CBD Oil as a Muscle Relaxant
While at first glance it may seem like the link between CBD oil’s relaxing effects and ET is a tenuous one, the biological properties of CBD suggest a significant potential for benefit. In addition to reducing spasticity, an additional way that CBD oil can relax muscles is through its reduction of anxiety and promotion of general relaxation. CBD oil is able to reduce levels of the stress hormone cortisol and induces higher levels of the feel-good hormone dopamine.
Not only can CBD help your muscles relax from a neurological point of view, but the cannabis plant also contains two anti-inflammatory substances that have been shown to act as muscle relaxants: Delta-limonene and Beta-myrcene.
With this evidence in mind, the likelihood that CBD oil can help those who suffer from ET looks positive. This then begs the question, why hasn’t CBD and ET research been conducted sooner?
The Barriers to CBD Testing
The red tape surrounding the use of CBD in clinical research has long been an issue for scientists across the U.S., with the clinical trial at UCSD being no exception. Despite many states, including California, having relaxed laws on the use of cannabis for medical and recreational purposes, federal law takes a much harsher stance.
The U.S. Drug Enforcement Agency (DEA) considers any derivative of cannabis to be an illegal substance and requires universities and research facilities to obtain cannabis products through the National Institute on Drug Abuse (NIDA). And getting materials from the NIDA is a notoriously slow process.
To complicate the matter further, the researchers on the UCSD study wanted to use CBD capsules, which aren’t available through the NIDA. In order for the trial to have been given the green light, permissions had to be sought to import CBD capsules from Canada, where medical marijuana is federally legal.
How to Use CBD oil for Essential Tremor
While the results from the trial at UCSD aren’t available yet, if you are struggling to carry out daily tasks due to ET, CBD oil may be an option worth exploring based on its beneficial biological properties.
There are two main cannabinoids found in cannabis: CBD and THC. Both work differently within the body’s endocannabinoid system to yield different health benefits and ideally, you’d take both by way of a full-spectrum product. A full-spectrum CBD oil is also more likely to contain limonene and myrcene, allowing you to experience the muscle relaxing properties of all the hemp plant’s natural compounds at an amplified level, thanks to the entourage effect. The entourage effect refers to the fact that substances in the whole hemp plant produce stronger effects when they are present together than they do on their own.
But, before buying a CBD oil product that contains THC, make sure you understand whether or not it is legal for you to do so. A full-spectrum CBD product with a higher THC content is only going to be available to people who live in a state with access to medical or recreational cannabis products. Everywhere else, CBD oil will fall under the federal guidelines, and must have a THC content that is 0.3% or less. If you live in a state where it’s illegal to consume THC, or you’d simply prefer not to consume it, look for a broad-spectrum CBD product. Broad-spectrum CBD oils contain all of the cannabinoids and terpenes of a full-spectrum product except for THC.
CBD Delivery Formats
There are lots of different CBD oil delivery formats available. Most people will choose a product based on their unique needs.
For many people with ET, a supplement routine that includes daily doses of CBD oil tinctures, capsules, or edibles is likely to be most effective. This will ensure that CBD is always in the system and working to create equilibrium over longer periods of time.
CBD capsules and edibles will provide the longest lasting relief, typically 4 to 6 hours, but will also take the longest to take effect. Due to the fact that they have to pass through the digestive system, it could take up to an hour for you to feel the benefits of a CBD edible or capsule.
For the sudden onset of tremors, an inhalant, like a CBD vape or CBD flower may be best. In these formats, the CBD is absorbed through the lungs, showing effects in a matter of minutes. When struck with debilitating tremors, time is of the essence. The only drawbacks of using an inhaled CBD product is that the effects are typically gone within an hour, and it is not always appropriate or convenient to vape or smoke.
CBD oil drops or tinctures may provide the best, most balanced solution. This format can easily be used as a daily supplement and the bottles are portable and discreet enough to be used for the sudden onset of symptoms. The effects do not appear as quickly as with CBD vapes or flower, but they typically occur within a half hour and can last anywhere from 2 to 4 hours. This format also makes it easy to control dosage and take more or less CBD oil as required. It is worth noting, however, that if tremors are severe enough, tinctures and drops may be complicated to administer on your own.

CBD Oil Dosage for Essential Tremor
Before you start taking CBD oil for ET, it is important to talk to your doctor. While CBD oil has very few side effects and is generally safe for use, it can interact with some common medications, so it is best to make sure that you are able to use CBD oil safely and effectively.
Unfortunately, there is no single dose that will work for essential tremor. What works for one person may not work for another. Start slowly with the lowest recommended dose listed on your CBD product. Once you get an idea of how you respond to CBD oil, you can adjust the dosage from there.
If you’re looking for a quick point of reference, at CBD Oil Review, we have analyzed hundreds of products and have come up with the following:
The CBD Oil Review Serving Standard is 25 mg of CBD, taken twice daily.
If this amount does not produce the results you were looking for, increase the dose by 25 mg every 3 to 4 weeks until the desired effects are achieved.
You can find detailed CBD dosage information and tips here, or speak to a naturopathic doctor for the most personalized CBD dosage advice.
The Best CBD Oil for Essential Tremor
If you are afflicted with ET and want to try treating it with CBD oil, there are a variety of products available that can be purchased easily, and legally, in most states. The best CBD oil to use for ET is one which is high quality and rigorously tested.
For that reason, it is recommended that you choose a brand which uses organically grown, sustainably sourced hemp to ensure that your CBD oil is free of harmful pesticides, fertilizers, and herbicides. Also, look for those that have a readily accessible Certificate of Analysis (COA), which will indicate that the products have been tested for heavy metals and other contaminants. A COA is most reliable if it has been produced by a third-party laboratory, as this removes any likelihood of bias in the results.

Does CBD Oil Help with Essential Tremors?
Tremors can be caused by various factors, from neurodegenerative diseases to anxiety, brain damage, aging, and withdrawal symptoms from addiction.
Scientists have been examining the health benefits of CBD for quite some time now, with great effort being fueled into research on how CBD may affect tremors.
The endocannabinoid system (ECS) controls an array of essential physiological processes, including motor functions and movement. Since tremors are muscle movements that involve back and forth rhythmic swaying, they perfectly fall into that bracket.
In turn, this suggests that the ECS can be a therapeutic target for people looking for effective tremor management.
CBD oil is the modulator of the ECS, but can it help with tremors?
This article explores how CBD affects tremors and what science says about its therapeutic potential in this subject.
Common Causes of Tremors
Tremors are involuntary movements of the body and can impact the hands, arms, head, face, legs, and voice. More often than not, tremors are caused by neurological disorders in the brain regions that control movement. Conditions that destroy or degrade the brain cells, like Alzheimer’s disease, Parkinson’s disease, or stroke, can trigger tremors.
However, they can also appear as a result of drug withdrawal or as the side effect of certain prescription medications. Tremors often appear during a stressful event when a person is going through anxiety.
So, while temporary tremors aren’t an alarming sign, chronic episodes may indicate a serious disease requiring medical attention.
Does CBD Help with Tremors?
Researchers have yet to find out how CBD affects tremors. CBD is widely studied for its ability to reduce the symptoms of movement disorders. So far, we know that CBD can reduce muscle spasms, convulsions, and tremors associated with conditions like epilepsy, Parkinson’s Disease (PD) , and Multiple Sclerosis (MS ). One study actually found that CBD reduced the intensity of tremors in patients with PD during their REM sleep stage.
The mechanism behind the potential positive effect of CBD on tremors isn’t well-known yet. However, scientists speculate that the ECS is the major therapeutic target in this relationship.
By indirectly acting on the cannabinoid receptors in the central and peripheral nervous system, CBD can ensure proper muscle movement and prevent tremors — at least hypothetically.
Let’s elaborate on that mechanism using the examples of different types of tremors.
Does CBD Oil Help with Hand Tremors?
As mentioned, CBD interacts with the ECS, which is a broad system of receptors and neurotransmitters that work to maintain homeostasis between essential bodily functions — including muscle movement.
When CBD regulates these receptors, it produces relaxing and antispasmodic effects; it can also block the release of pro-inflammatory proteins known to damage the nervous system.
Through these pathways, CBD can ease symptoms of tremors on top of effectively acting as a neuroprotectant.
One study on mice showed that CBD produced superior results in tremor relief without showing any life-threatening side effects or causing impairment. The authors also determine what receptors may be involved in these effects, suggesting that CBD engages with the 5-HT1A receptor to prevent tremors by activating the TRPV1 receptor .
Many of the prescription drugs that people usually take for tremors carry a risk of dangerous side effects. CBD, in turn, comes with anti-tremor properties and has a good safety profile with only minor side effects when overdosed.
CBD Oil Effects on Parkinson’s Disease Tremors
As mentioned earlier, tremors generally result from neurodegenerative diseases, such as Parkinson’s Disease (PD). This non-reversible disorder of the central nervous system causes people to experience impaired posture, uncontrolled muscle movements, rigid muscles, and hand tremors.
In 2015, Neurotherapeutics published a study that examined the efficacy of medical cannabis for PD symptoms, concluding that the majority of the subjects showed significant improvements at the end of the treatment .
Patients from the Prague Movement Disorder Centre also reported improved quality of life due to significant symptom relief after using cannabis .
That being said, medical cannabis isn’t the same as hemp-derived CBD oil. The former may contain higher amounts of THC on top of CBD and other cannabinoids, while the latter only comes with 0.3% of THC or less — meaning the effects of cannabis-derived CBD oil may not be replicated with hemp-derived extracts.
CBD Oil for Elderly Tremors
More studies are needed to determine if CBD can be used as monotherapy to manage tremors and other symptoms among the elderly and patients with PD.
However, some neuroscientists acknowledge that CBD may act as a neuroprotectant that helps with PD. A study published in the British Pharmacological Society mentioned that CBD could modulate neurotransmission and prompt neurogenesis (formation of new brain cells) .
These effects were tested as a monotherapy, and in conjunction with other cannabinoids, among patients with Huntington’s disease, multiple sclerosis, and Parkinson’s Disease.
Other Types of Tremors that CBD Oil Can Help With
Aging and neurodegenerative disorders are just two causes of tremors that CBD might help with. But can it also relieve tremors induced by stress or brain injuries?
CBD Oil for Anxiety Tremors
In a recent study published by the Journal of Psychopharmacology, the authors found that CBD reduced anxiety and tremor amplitude among PD patients. The research team used a dose of 300 mg CBD/day, which provided significant benefits for heart rate, blood pressure, and frequency of tremors among the subjects .
The scientists also noted a reduction in anxiety-related tremors during a simulated public speaking test.
Other studies implicate that CBD can have therapeutic benefits for people with anxiety disorders and neuropsychiatric conditions.
CBD Oil vs. Brain Damage Tremors
An animal study from Pharmaceuticals found that CBD may positively affect brain regeneration after an injury and ischemic stroke (one caused by the blockage of blood flow) .
The study found that CBD exerted neuroprotective actions and assisted in repairing communication between neurons in the brain. The researchers administered 3mg/kg of CBD per day to mice models with cerebral ischemia — reporting improved motor coordination and neurological scores.
The authors concluded that more research would help establish CBD’s clinical value on brain injury and stroke.
Best Type of CBD to Use for Tremors
There are three main types of CBD you can choose from: full-spectrum CBD, broad-spectrum CBD, and CBD isolate.
Full-spectrum CBD is made from the whole hemp plant, and as such, it contains all the cannabinoids present in hemps, such as CBD, CBN, CBG, CBC, and trace amounts of THC. It also contains a lot of terpenes, which are volatile molecules that modulate the activity of cannabinoids.
These compounds create a unique synergy known as the entourage effect. This concept was brought up in 1988 and further elaborated on in 2011 by E.B. Russo, an esteemed neuroscientist and cannabis expert. In the entourage effect, the sum of all active ingredients in the plant is more potent therapeutically than each compound in isolation.
Therefore, if you want to reap the most benefits of your CBD oil, opt for full-spectrum extracts.
Broad-spectrum CBD is very similar to its full-spectrum counterpart, but it doesn’t contain any THC. The intoxicating ingredient has been removed after initial extraction so that the user can benefit from some of the entourage effects without worrying about failing a drug test.
You can also choose CBD isolate, which is pure CBD that has been crystallized and infused into the same product formats as the other types of CBD. The advantage of CBD isolates over other types of CBD oils is the lack of flavor and aroma; that being said, there’s also an obvious downside — the lack of entourage effect.
Once you know your desired type of CBD, it’s time to consider the best form for your tremors. Here we’ll explore the two basic formats of CBD: oils and capsules.
CBD Oil vs. Capsules for Essential Tremors
Choosing between CBD oil and capsules for tremors boils down to mapping out your needs and knowing the pros and cons of both products.
CBD oil is administered under the tongue. From there, it absorbs through tiny blood vessels in the mouth, reaching the bloodstream. The effects of CBD oil are usually noticeable within 15-30 minutes after administration, lasting for up to 6 hours. The peak concentration levels of CBD oil are usually reached after 1.5 hours. The bioavailability of CBD oil is around 35%, meaning that slightly over one-third of the ingested content ends up in your system.
With CBD capsules , the route of administration causes a delay in effects. Since CBD needs to pass through the digestive system, the effects may need about 30 to 90 minutes to take hold, depending on your metabolism and whether you take CBD on a full or empty stomach. While CBD capsules offer lower bioavailability — up to 20% — they last longer than oils because CBD is released gradually from the liver.
If you’re looking for more pronounced and faster-acting effects, CBD oil is a better option. Capsules come in handy if you have your supplementation scheduled up and don’t mind the delay. CBD capsules also mask the earthy flavor of CBD oil because the extract is contained in a soft gel shell, which is another argument in their favor.
CBD Oil Dosage for Tremors
Dosing CBD depends on a range of individual factors, including your weight, metabolism, age, the severity of tremors, and unique body chemistry.
According to a review of studies evaluating the effects of different CBD doses in clinical populations, an effective dose can range from 1 to 50 milligrams per day. The dosage can be increased when you don’t feel any difference after, say, one week. From there, you can gradually adjust the amount of CBD to the point where it effectively reduces tremors.
When you use CBD for tremors, taking high doses may cause a few mild side effects , such as:
- Dry mouth
- Appetite fluctuation
CBD can also interact with many pharmaceutical substances , so consult your doctor before adding CBD to your daily routine if you take any medications.
Bottom Line: How Can You Use CBD to Help with Tremors?
CBD’s potential in reducing different types of tremors is, without a doubt, promising. Several studies have already shown that it has the ability to improve primary motor symptoms of neurological conditions such as Parkinson’s Disease.
These positive results from the aforementioned studies shed new light on the therapeutic use of CBD for tremors. Products like CBD oil can significantly improve motor disorders without the dangerous side effects associated with pharmaceuticals.
Tremor sufferers can also adjust their lifestyle to naturally improve their lives, mainly by exercising, reducing alcohol, practicing meditation, and avoiding caffeine.
A consultation with a holistic or integrative neurologist should help you find the right set of remedies and adjustments to help you cope with tremors without frustration.

Best CBD Oil for Tremors – August 2022
Tremors are caused by conditions, such as neurodegenerative diseases, anxiety, and brain injury.
Scientific studies have yet to determine how cannabidiol ( CBD ) may affect tremors. However, scientists are now investigating its capability to reduce symptoms of the movement disorder .
In January 2019, the University of California, San Diego , called for volunteers for a double-blind study on how medical cannabis may affect essential tremors (ET) (6) .
Dr. Nahab explained that there are currently no pharmacological agents developed for ET. For years, epilepsy medications have been used as off-label treatment.
Also, modern treatment for severe ET involves deep brain stimulation ( DBS ) surgery. DBS is an invasive procedure where a device is implanted into the brain.
The researchers, led by neurologist Dr. Fatta Nahab , are expected to share their findings in December 2020 (7) .
In a clinical trial conducted on Parkinson’s disease patients by the University of Colorado, the authors examined CBD ’s efficacy and tolerability (8) . The study measured appropriate CBD dosing and its ability to reduce tremors.
A positive outcome from ongoing CBD studies may lead to a natural solution to treating tremors.
Although CBD ’s efficacy on tremors is yet to be seen, many studies attributed its positive effects on several brain conditions, such as neurodegenerative diseases, stroke, brain injury, and anxiety (9) .
CBD vs. Neurodegenerative Disease-Related Tremors
Parkinson’s disease (PD) is a non-reversible disorder of the central nervous system . Symptoms of PD may include hand tremors , rigid muscles, impaired posture, uncontrolled muscle movements , and many more.
Neurotherapeutics released a study in 2015 that discussed how individuals who were experiencing severe PD-related pain and tremors showed significant improvements after medical cannabis treatment (10) .
Furthermore, patients from the Prague Movement Disorder Centre also reported tremor improvements after using cannabis (11) .
Medical cannabis ( medical marijuana ) does not guarantee the same amount of compounds as one would get from a full-spectrum CBD oil .
However, the two main subspecies of cannabis (Cannabis indica and Cannabis sativa) are abundant with CBD (12) .
The US federal law prohibits CBD products from containing more than 0.3% tetrahydrocannabinol ( THC ), the cannabinoid that causes psychoactive effects. Meanwhile, medical cannabis may contain THC levels higher than 0.3%.
More comprehensive studies are essential to determine how CBD , as a monotherapy, may affect rigidity and tremors among individuals with PD.
However, some researchers acknowledge that CBD may have neuroprotective properties that can help with PD.
A study posted in the British Pharmacological Society mentioned that CBD might be able to modulate neurotransmission and improve neurogenesis (formation of new neurons) (13) .
The study added that CBD , as a monotherapy, or if used in conjunction with other phytocannabinoids, had demonstrated significant effects among individuals with Parkinson’s disease , Huntington’s disease, and multiple sclerosis (14) .
The authors continued that CBD was able to activate the G-protein receptors, leading to an increase of adenosine (a building block for DNA and RNA) concentrations. This response resulted in the reduction of inflammatory cells in the brain (15) .
According to another study, systemic inflammation in the brain can lead to an exaggerated synthesis of proinflammatory cytokines, a protein released by the immune system (16) .
The release of these proinflammatory proteins can lead to both acute and chronic neurodegeneration. Long-term studies are needed to confirm any potential benefits of CBD for neurodegenerative or other disorders besides certain childhood seizures.
CBD vs. Anxiety-Related Tremors
A recent study posted by the Journal of Psychopharmacology has shown how CBD reduced anxiety and tremor amplitude among PD patients (17) .
The study specified that a 300mg/d (milligrams per day) CBD dose produced significant differences in blood pressure , heart rate, and frequency of tremors among the participants.
The study also saw a reduction in anxiety-related tremors during a simulated public speaking test.
Other studies have mentioned how CBD might have therapeutic benefits for individuals with anxiety and other neuropsychiatric conditions (18) .
CBD vs. Brain Injury and Stroke Tremors
An animal study from Pharmaceuticals addressed how CBD may positively affect brain injury and ischemic stroke (stroke caused by lack of blood blow) (19) .
The study found that cannabinoids might facilitate neuroprotection and neuro repair response in the brain.
A dose of 3mg/kg (milligrams per kilogram) CBD administered to mice models with cerebral ischemia improved the neurological scores and motor coordination (20) .
The study concluded that more research is needed to evaluate CBD ’s clinical value on brain injury and stroke.
CBD vs. Other Movement Disorders
A study mentioned that basal ganglia dysfunction is responsible for causing movement disorders , like tremors and chorea (21) .
The British Journal of Pharmacology released a study that supported cannabinoid ’s affinity in activating receptors in the basal ganglia (22) .
The authors added that the activation might have therapeutic potential in treating Huntington’s disease (HD) and Parkinson’s disease (PD) symptoms.
A 2018 study released in Neurochem evaluated how CBD and other cannabinoids might have neuroprotective effects in an HD cell culture model (23) .
In the study, CBD , tetrahydrocannabinol ( THC ), and cannabinol (CBN) showed 51-84% protection against Huntington-induced cell death.
Moreover, a review from Neurology mentioned that CBD might have reduced chorea among patients with HD. A dose of 300mg/d (milligrams per day) CBD was administered to patients orally for three weeks.
Mild improvements in choreic movements (5 to 15%) were reported in the first week. In the second week, further improvements (20 to 40%) were reported (24) .
Chorea, like tremors, is a movement disorder . However, a tremor is classified for its rhythmicity and predictability, while chorea has more random and untimely movements (25) .
Meanwhile, a contrasting study was released by Pharmaceuticals, where a controlled clinical trial showed no significant improvements among 15 patients with HD.
In the study, patients were treated with 700mg/d for six weeks. The study did acknowledge that high doses of oral CBD (150-600 milligrams per day) might hold a therapeutic effect on social anxiety, insomnia, and epilepsy (26) .
Also, CBD is a medically-accepted therapy for epileptic spasms. In 2018, the FDA approved Epidiolex as a pharmaceutical drug for rare child epilepsies. The main active ingredient in the drug is CBD (27) .
Although there are no studies that have used Epidiolex as off-label medication for tremors, another antiepileptic drug, Primidone , is a medically-accepted off-label treatment.
How CBD Oil Works to Help With Tremors
The human endocannabinoid system (ECS) is a complex system made of G-protein-coupled receptors, cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2).
These receptors are located throughout the human body. Most are present in the central nervous system (CNS) and peripheral nervous system (28) .
Many researchers have discussed how modulating the ECS might result in many therapeutic promises in a wide range of pathological conditions and diseases (29) .
Researchers also learned that there is a high density of cannabinoid receptors in the cerebellum and basal ganglia (areas that control motor function).
These receptors have caused many researchers to examine how tremors caused by CNS-related diseases can be alleviated.
A study published in the British Journal of Pharmacology explained how cannabinoids , such as THC and CBD , may have the ability to interact with CB1 and CB2 receptors (30) .
The authors mentioned that CBD displays high potency in modulating CB1 and CB2 receptors.
Another study hypothesized that alterations to the ECS might be beneficial to Parkinsonian tremors. The study also called on researchers to consider testing the range of individual cannabinoids for their therapeutic potential in managing tremors (31) .
The Pros and Cons of CBD Oil for Tremors
- CBD might be able to modulate neurotransmission and improve neurogenesis (formation of new neurons) (32) .
- CBD has demonstrated significant effects among individuals with neurological disorders, such as Parkinson’s disease , Huntington’s disease, and multiple sclerosis (33) .
- CBD might help reduce inflammatory cells in the brain (34) .

- CBD has been acknowledged as well-tolerated and safe for daily use (36) .
- CBD has been found to improve motor functions in animal models with induced ischemia (37) .
- There is a lack of evidence if CBD , as a monotherapy, can help improve essential tremors or treat any disorder other than certain childhood seizures.f
- CBD is poorly regulated. Individuals are encouraged to do extensive research before choosing a CBD brand.
- CBD may cause side effects , such as dry mouth, diarrhea, and loss of appetite (38) .
- According to the US Food and Drug Administration ( FDA ), CBD may cause liver injury if consumed in extremely high doses (39) .
How CBD Oil Compares to Alternative Treatments for Tremors
There are no recommended alternative treatments for tremors except for off-label use of other pharmaceutical drugs and compounds (40) .

How to Choose the Best CBD Oil for Tremors
For individuals who want to improve tremor symptoms, it may be appropriate to use full-spectrum CBD oil .
Full-spectrum CBD oil contains all the cannabinoids present in hemp plants, such as CBD , cannabigerol (CBG), cannabinol (CBN), and THC .
The previous studies mentioned in this article mostly used cannabis as a trial treatment.
Most full-spectrum CBD products contain all the phytocannabinoids one can find in a cannabis plant (43) . However, the product may not contain more than 0.3% THC due to the United States ’ federal law .
The broad-spectrum CBD oil is another product that contains all the cannabinoids with 0% THC . Broad-spectrum oil is recommended for individuals who do not want THC in their system.
Moreover, individuals who cannot tolerate other cannabinoids may opt for CBD isolates, which contain only pure CBD .
CBD Dosage for Tremors
The recommended dosage for individuals who want to take CBD for brain- or CNS-related conditions is less than 1 milligram to 50 milligrams per day (44) . The dosage can be increased when the body gets used to CBD .
A high CBD dosage is not recommended due to lack of information on how CBD may affect symptoms of essential tremors .
How to Take CBD Oil for Tremors
When taking CBD oil for tremors, the fastest delivery method is through vaping. A study had mentioned that the lungs are a very efficient mechanism for drug delivery.
The authors continued that CBD inhaled through aerosols or vaporizations can deliver plasma concentrations that can be felt within 10 minutes or less (45) .
Vaping is also recommended for its accessibility. Individuals who are looking to find a quick relief can vape CBD at home or while traveling.
However, there had been several reports that vaping can potentially cause harm, such as chemical irritation, allergic reactions, shortness of breath, and chest pains (46) .
Individuals may also opt for oral or sublingual (under the tongue) delivery, such as CBD capsules or CBD tinctures . The oral administration allows for optimal absorption (47) .
Some CBD tinctures may have an earthy taste and smell due to terpenes and flavonoids added into the concentration. Individuals who do not care for this distinct flavor can opt for CBD capsules.
Individuals must discuss their treatment options with a licensed physician before using CBD for their medical conditions .
Reports on CBD ‘s therapeutic potential in improving PD’s primary motor symptoms have resulted in scientists pursuing the mechanism behind its efficacy (48) .
A positive outcome of these studies could significantly impact individuals who suffer from tremors.
