CBD Oil For Arthritis
Arthritis is understood to mean various inflammatory joint diseases with different causes. It is important to first differentiate arthritis from arthrosis because they are often confused since both affect the joints. Arthrosis is excessive joint wear due to articular cartilage degradation. Arthritis is a chronic inflammation of the joints, which in rare cases can also affect internal organs.
The term “arthritis” summarizes inflammatory joint diseases. They may have different causes, distinguishing between infectious arthritis (for example, by bacteria) and non-infectious arthritis.
The most common form of arthritis is rheumatoid arthritis. It affects around one to two percent of all adults, depending on their age. It is one of the non-infectious-related arthrites. In this disease, the body’s defense (immune system) is disturbed and attacks the joints and endogenous tissue. The cause for this is not yet clear.
CBD, also known as cannabidiol, plays a role in immune system modulation, which means it can help in treating autoimmune conditions like rheumatoid arthritis. Also, the strong anti-inflammatory properties of CBD and the interaction and inhibition of certain receptors make CBD a potential form of treatment for these conditions. Cannabidiol (CBD), Tetrahydrocannabinol (THC) and the byproduct of its metabolism have anti-inflammatory and pain-killing (analgesic) properties. However, there are other properties of cannabinoids, especially CBD, such as the ability to suppress T-cells, affect the immune system and how cannabinoids affect the so-called GPR55 receptors associated with the development of arthritis.
In this article, we look at the currently known properties and studies that make CBD and other cannabinoids a potential treatment for arthritis.
So stay tuned!
Causes and Symptoms of Arthritis
When rheumatoid arthritis affects a person, it attacks normal tissue components as invading pathogens cause inflammation. The inflammation attacks the lining of the joints and then spreads to cartilage and bone while causing destruction therein and making joints immobile and deformed. There are environmental and genetic factors involved in this reaction.
Symptoms vary from one person to another and they may include swelling, pain in joints, persistent fatigue, stiff joints especially in the morning, sleep difficulties owing to pain and weakness in muscles.
Making a diagnosis is not so hard as the disease shows itself over a few months. Only an expert can tell after complete examination and check-up. Blood tests also help identify rheumatoid arthritis factor, which is present in almost 80 percent of people suffering from rheumatoid.
Arthritis: Risk Factors
There are certain factors that increase the chances of developing rheumatoid arthritis. These are age (25 to 45), gender (75 percent of patients are female), family history of rheumatoid arthritis, ethnicity (Americans and Caucasians have a higher risk) and obesity factors.
There are ways, through proper methods and techniques, to alleviate the discomfort. Physiotherapy that involves heat, cold and exercises to relieve stiffness and pain is an effective way.
Rest and occupational therapy are also effective. Drugs are also available including NSAIDs (non-steroidal anti-inflammatory drugs) to treat inflammation although these have side effects. Corticosteroids are also used to suppress immune reaction. DMARDs (disease modifying anti-rheumatic drugs) slow down the progress of the disease but they can bring about serious side effects.
CBD for Arthritis: CBD Oil as a Treatment?
CBD oil has shown lots of improvement in the treatment of arthritis. According to research, cannabidiol helps reduce the pain and inflammation caused by arthritis of all types such as rheumatoid arthritis, gout, osteoarthritis, psoriatic arthritis and other types of inflammatory joint conditions.
Cannabidiol (CBD) is a compound (Cannabinoid) that is found in all Cannabis species of this genus of plants. So it is present in countless Hemp and Cannabis Strains.
Doctors have successfully treated rheumatoid arthritis with CBD oil that gives relief from inflammation and pain. According to a study conducted in 2006, patients used CBD oil for a five-week period and experienced improvement in less pain and inflammation. It also slowed down the progression of rheumatoid arthritis considerably.
Patients who are fed up with drugs and want to go for a natural treatment of this disease can use CBD oil according to the instructions given by experts.
What Qualities Does CBD Have in the Treatment of Arthritis?
Cannabidiol Suppresses T-Cells
T-cells form a group of white blood cells that serve the immune system. T-cells together with the B lymphocytes represent the acquired immune response. The “T” in the name stands for the thymus in which the cells mature. These T-cells thus represent an important part of the human immune system.
Rheumatoid arthritis is one of the autoimmune diseases in which the immune response of the body can be directed against the body’s own processes/components, an overreaction of the immune system to the body’s own non-pathogenic substances. The development of T-cells serves to recognize and combat foreign substances, which could pose a danger to the body.
The formation of T-cells is also seen as a co-causative agent in the development of Rheumatoid arthritis. Research has shown that the use of CBD suppresses the development of these T-cells, which in turn represents one of the immunosuppressive properties of CBD (cannabidiol) and, among other things, its anti-inflammatory properties.
This property of suppressing the development of T-cells in the autoimmune disease rheumatoid arthritis is one of the benefits of the use of CBD in treating RA.
The Effects of CBD on the Immune System in Arthritis
As aforementioned, CBD also affects the immune system of the body. Research has shown that CBD can regulate and balance overstimulation of the immune system. Overstimulation (overreaction) often leads to autoimmune diseases such as multiple sclerosis, psoriasis, arthritis or, in general, to chronic inflammation.
People who suffer from rheumatoid arthritis usually also have to fight with inflammation in the joints. These inflammations are accompanied by severe pain and immobility. The strong anti-inflammatory properties of CBD may, therefore, be helpful in chronic inflammatory processes in RA.
- The anti-inflammatory properties of CBD are mainly due to the regulation of an over-stimulated immune system. In chronic inflammation caused by an autoimmune disease, CBD can be very helpful.
- Inflammation, however, is an important body process that normally serves to localize foreign bodies, isolate them, and heal damaged tissue. Therefore, it is not always advisable to suppress inflammation, not even with CBD.
Studies on the Use of CBD in the Treatment of Arthritis
Since these properties of CBD described above and the resulting advantages in the use of CBD and other cannabinoids in rheumatoid arthritis are well known, some studies have been carried out here as well. We took a closer look at four studies that all used a different approach and gave interesting results. Let’s consider the results of these studies.
Cannabis-Based Medicine For Pain Caused By Rheumatoid Arthritis
This is the first controlled trial of a cannabis-based medicine (CBM) in rheumatoid arthritis. This study is a preliminary assessment of the tolerability and efficacy of Sativex (a pharmaceutical cannabis preparation) in the treatment of pain associated with rheumatoid arthritis.
Sativex is a cannabinoid preparation containing both THC and CBD in a ratio of approximately 1: 0.8. So this is not a pure CBD product. Nevertheless, this study is very interesting and as CBD is also a constituent of this product, we want to take a look at it.
In this study, 58 patients underwent a double-blind study with Sativex and a placebo, to test the efficacy and tolerability of Sativex. The cannabis-based medicine (CBM) was administered in the evening and the next morning a review was conducted. Half of the group received a placebo, the other half received CBM (Sativex). This procedure was performed over five weeks.
The assessment was based on the following criteria:
- Pain on movement
- Pain at rest
- Morning stiffness
- Sleep quality
In the evaluation of the five-week treatment, the following result was found:
The CBM (Sativex) was able to significantly improve pain on movement, pain at rest and quality of sleep when compared to the placebo. There was no difference in morning stiffness. However, the baseline values were also very low and it is more difficult to detect a difference.
There was no adverse effect on the inflammatory symptoms or severe side effects of the cannabis preparation used in this treatment. In general, the side effects were mild to moderate in nature.
The conclusion of this study:
A significant analgesic effect was observed in the treatment of RA patients with Sativex and the disease activity was significantly suppressed. These findings are clinically relevant and suggest that further detailed investigation is required. The cannabinoids THC and CBD obviously have a strong positive effect in the treatment of RA patients. The specific cannabinoids and their respective proportionalities which played a decisive role in this study was not investigated
CBD as an Oral Anti-Arthritic Therapeutic in Induced Arthritis
Another therapeutic potential of CBD in arthritis has been found in an experiment on mice.
In this study, mice were induced with arthritis, which is called “murine collagen-induced arthritis” in medical terms. Either a classic acute or chronic recurring arthritis was triggered.
Once clinical symptoms of arthritis were detected, the mice were then given CBD.
It turned out that in both arthritis models, treatment with CBD effectively blocked the progression of arthritis.
The efficacy of CBD was confirmed in both cases of administration and was administered as follows:
- Intraperitoneal: Through an injection into the abdominal cavity
- Oral: By administration in the mouth
An optimal effect was observed at the following doses:
- 5 mg CBD / 1 kg body weight per day with intraperitoneal
- 25 mg CBD / 1 kg body weight per day when administered orally
The clinical improvement in the treated mice is associated with the protection of the joints from severe damage. After completion of the treatment, the investigations were continued in two ways:
- Ex- Vivo: Refers to processes in which living biological material, in particular, cells, tissues or organs, is taken from a living organism and usually cultivated outside it for a limited time.
- In Vitro: Are organic processes that take place outside of a living organism, as opposed to those that occur in the living organism (in vivo)
In Ex-Vivo, a reduction in the specific substances associated with the formation of induced arthritis was found in the lymphs and a reduction of tumor necrosis factor by so-called knee synovial cells. In-vitro effects showed a dose-dependent suppression of lymphocyte proliferation (growth of lymphocytes) and the blockade of zymosan-induced reactive oxygen burst.
The data in this study show that CBD has a strong anti-arthritic effect on collagen-induced arthritis (CIA) due to its immunosuppressive and anti-inflammatory properties.

The Role of the Endocannabinoid System in Osteoarthritis Pain
The degenerative joint disease osteoarthritis is associated with articular cartilage degradation and it leads to neuropathic and nociceptive pain.
- Neuropathic pain: Is caused by damage or diseases of the nervous system. While in all other types of pain – the so-called nociceptive pain – the nerve tracts act only as a “transmitter” of pain stimuli, in neuropathic pain, the nervous system itself is the cause of pain.
- Nociceptor: Is a free sensory nerve end, which generates electrical signals in case of threatened or damaged tissue by thermal, chemical or mechanical Noxen. Nociceptors are the point of departure for nociception and their irritation is typically accompanied by pain.
Currently, there are no drugs that can control the disease progression of osteoarthritis, so the current therapeutic approaches are very limited. However, there are more and more preclinical studies suggesting the endocannabinoid system as a therapeutic target for osteoarthritic pain. Some studies have shown that the properties of cannabinoids have an antinociceptive effect in osteoarthritis and suggest an active involvement of the endocannabinoid system in the pathophysiology of this disease.
The endocannabinoid system extends through the body through many cannabinoid receptors that interact directly or indirectly with the cannabinoids. In addition, the ECS (endocannabinoid system) plays a physiological role in the regulation of inflammation, pain and joint function. All this supports the therapeutic potential of cannabinoids such as CBD, THC, CBN etc. in the treatment of osteoarthritis.
To date, too few clinical evidence (studies) have been provided to substantiate these promising preclinical evidence for the use of cannabinoids in the treatment of osteoarthritis. To officially confirm cannabinoids as a therapeutic solution for osteoarthritis, there is still a long way to go, which will hopefully start soon with new studies.
