This advance in knowledge of its mechanism of action has widened the availability of various CBD-based products, such as CBD oils, capsules and even cosmetic creams.
As CBD experts, we see cannabidiol as a molecule full of promise, rich in as yet largely untapped therapeutic potential. We invite you to continue your exploration and discover for yourself the many benefits CBD has to offer.
What is CBD?
Definition of CBD
Cannabidiol, more commonly known as CBD, is a natural compound found in the cannabis plant and its variety, hemp. It is one of many cannabinoids present in these plants, and stands out for its non-psychotropic properties, unlike THC (tetrahydrocannabinol), which is responsible for the psychoactive effects associated with cannabis consumption.
Chemical structure of CBD
The CBD molecule has a chemical structure very similar to that of THC. It is made up of 21 carbon atoms, 30 hydrogen atoms and 2 oxygen atoms. This similarity partly explains the interactions between CBD and our body's endocannabinoid system. Nevertheless, CBD has no psychoactive effects, i.e. it does not affect the user's perception or psychological state.
Origin of CBD
Le CBD est extrait de la plante de cannabis et notamment de sa variété, le chanvre (cannabis sativa). Le chanvre industriel est en effet particulièrement riche en cannabidiol et présente des concentrations très faibles de THC (<0,2% en Europe), ce qui en fait une source privilégiée pour l'extraction du CBD.
History of CBD
The use of the cannabis plant dates back thousands of years, but it was only in the middle of the 20th century that the first scientists began to study the various chemical compounds present in this plant. CBD was first isolated in 1940 by an American researcher, Roger Adams, and its chemical structure was determined a few years later by a South African team led by Ralph Mechoulam.
Growing industrial hemp
Industrial hemp is grown mainly for its fibers and seeds, but also for CBD production. The hemp varieties used are selected for their low THC content and high cannabidiol concentrations. Europe requires hemp to be grown with a maximum THC content of 0.2%, while in the USA, the limit is set at 0.3%.
CBD extraction
Several CBD extraction methods exist, some of which preserve the integrity of other compounds present in the plant, such as terpenes or other cannabinoids. The main extraction methods include :
- CO2 extraction: a sophisticated technique that uses carbon dioxide to separate CBD from other plant components.
- Oil extraction: this method involves macerating CBD-rich plant material in an oil, often olive or coconut, to transfer its active ingredients into the oil.
- Solvent extraction: this method uses solvents to dissolve and recover the plant's active compounds. Ethanol is commonly used as a solvent, but more aggressive solvents such as hexane can also be employed.
Legality of CBD
The legality of CBD varies from country to country. Indeed, each legislation treats the subject differently, which can lead to some controversy and confusion.
CBD and French legislation
In France, CBD is considered legal if extracted from authorized hemp varieties containing less than 0.2% THC. However, the marketing of products containing CBD is subject to certain rules. For example, only products derived from the plant's seeds and fibers are authorized for use as dietary supplements or cosmetics. Preparations containing CBD must not promote therapeutic claims, as cannabidiol is not a medicine.
Europe and CBD
Throughout the European Union, CBD is authorized on condition that it is extracted from hemp varieties containing less than 0.2% THC. Nevertheless, each member country may have its own regulations concerning the sale and use of CBD-containing products, so it's important to find out about local laws before consuming or purchasing.
Legality of CBD in the United States
In the United States, the legality of CBD differs according to state and federal legislation. Since the 2018 Farm Bill, CBD derived from industrial hemp containing less than 0.3% THC is legal at federal level. However, some states have adopted more restrictive laws regarding CBD, particularly with regard to the marketing and possession of these products.
The properties of CBD
Anxiolytic effects of CBD
CBD has been shown to possess anxiolytic properties, meaning it can help reduce anxiety and stress. Several studies have highlighted its potential in the treatment of various anxiety disorders:
- Generalized anxiety disorder (GAD): a study of GAD patients showed that CBD significantly reduced anxiety symptoms.
- Post-traumatic stress disorder (PTSD): CBD has also shown promising results in the treatment of PTSD, notably by helping patients to control their traumatic memories and reduce the associated emotional impact.
- Social anxiety disorder (SAD): preliminary research suggests that CBD may help people with SAD reduce their anxiety in specific social situations.
Thus, the anxiolytic effects of CBD could offer an interesting alternative to traditional drug treatments in the management of anxiety.
Anti-inflammatory effects
Numerous studies have demonstrated CBD's anti-inflammatory properties, which may help treat a variety of inflammation-related conditions. In addition to its aforementioned analgesic effects, studies have also suggested that CBD may play a beneficial role in the management of chronic pain. For example, a systematic review of 18 clinical trials concluded that the use of cannabinoids, including CBD, could help improve the quality of life and functional abilities of patients suffering from chronic non-cancer pain.
CBD's anti-inflammatory effects could also help alleviate some of the pain associated with persistent inflammation, such as that caused by arthritis or fibromyalgia. By targeting the receptors of the endocannabinoid system involved in the inflammatory response, CBD could potentially relieve patients suffering from chronic pain and offer them greater comfort in their daily lives.
Analgesic effects
CBD is also being studied for its pain-relieving properties. Several studies have highlighted its analgesic potential:
- Neuropathic pain: CBD seems to help alleviate the pain associated with certain nerve pathologies, such as multiple sclerosis or diabetic neuropathy.
- Inflammatory pain: a study on rats showed that CBD administration significantly reduced the pain and inflammation associated with arthritis.
- Migraines: some preliminary research indicates that CBD may be useful in the management of chronic migraines, although more studies are needed to confirm these findings.
The analgesic effects of CBD could therefore be an interesting non-opioid option for relieving various types of pain.
Fighting epilepsy
One of the most promising areas of CBD research is in the treatment of epilepsy. Several studies have demonstrated that CBD can help reduce the frequency and intensity of epileptic seizures in patients with forms resistant to conventional treatments:
- Dravet syndrome: a clinical study showed that CBD treatment significantly reduced convulsive seizures in children suffering from Dravet syndrome, a form of severe epilepsy mainly affecting young children.
- Lennox-Gastaut syndrome: in a study involving patients with this syndrome, the use of CBD as a complementary treatment led to an average reduction in the number of atonic seizures (sudden falls) of 43.9%.
In view of these encouraging results, CBD has been approved by some regulatory agencies, such as the FDA in the USA, for the treatment of certain forms of epilepsy.
Treatment of sleep disorders
Last but not least, CBD is also being studied for its potential to treat sleep disorders. Several research studies have suggested that CBD supplementation could :
- Improve sleep quality: some studies have shown that administering CBD to patients suffering from insomnia led to a significant improvement in the quality of their sleep.
- Regulating sleep-wake cycles: a study on rats revealed that CBD could help regulate phases of wakefulness and rest by acting on receptors involved in regulating sleep-wake cycles.
- Reduce nightmares: preliminary research has also suggested that CBD may help reduce the occurrence and intensity of nightmares in patients with REM sleep disorder.
CBD's effects on sleep could thus represent a promising new approach to the treatment of sleep disorders such as insomnia or parasomnias.
All in all, CBD offers interesting therapeutic potential in a variety of fields, thanks in particular to its anxiolytic, analgesic, anticonvulsant and sleep-enhancing effects. Although more studies are needed to confirm these findings and specify the optimal ways to use CBD, this molecule is attracting growing interest in medical research and could well offer new solutions to patients seeking treatment.
What disease does cbd treat?
First of all, before going any further in this paragraph, CBD does not cure any disease! If you're wondering what disease CBD cures, the answer is varied and above all simple: CBD doesn't cure.

- It stimulates the regeneration of damaged tissue,
Thus, using CBD to treat rheumatism can bring significant relief to sufferers.
Osteoarthritis and the role of CBD
Osteoarthritis is a degenerative joint disease that generally affects the elderly. The progressive degradation of cartilage leads to pain, joint stiffness and chronic inflammation.
Several studies have revealed that CBD may be useful in the treatment of osteoarthritis by acting on several fronts:
- Its analgesic properties relieve pain.
- It reduces inflammation thanks to its powerful anti-inflammatory effects.
- It protects cartilage by inhibiting certain enzymes responsible for its degradation.
In short, CBD helps relieve the symptoms of osteoarthritis and may help limit its progression.
Multiple sclerosis: a complex disease fought with CBD
Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system. It causes destruction of the protective sheath surrounding the nerves - known as myelin - resulting in motor, sensory and cognitive disorders, as well as pain.
CBD is increasingly being used to treat MS symptoms because of its many benefits:
- It reduces the muscle spasms and stiffness that affect MS sufferers.
- It relieves the neuropathic pain often experienced by patients suffering from this disease.
- It soothes the inflammation of the central nervous system involved in MS.
In this way, CBD opens the way to a qualitative improvement for people with multiple sclerosis.
Sleep disorders: CBD as a natural solution
Sleep disorders are a group of problems affecting the quality and duration of nocturnal rest. They include insomnia, frequent night-time awakenings, nightmares and difficulty falling asleep.
CBD has relaxing and anxiolytic properties thatcan help people suffering from sleep disorders to find restorative rest :
- It helps you fall asleep by acting on the serotonin receptors involved in sleep regulation.
- It improves sleep quality by reducing the anxiety and stress that can disrupt nocturnal rest.
The use of CBD soothes the body and mind, promoting restful sleep.
Depression: a mood disorder combated by CBD
Depression is a mental disorder characterized by persistent sadness, loss of interest in daily activities, sleep disturbances and lack of energy. Traditional antidepressants have been shown to be effective in treating depression, but they can also cause undesirable side effects.
CBD is an interesting alternative for treating depression, because it has several advantages:
- It regulates mood through its interaction with receptors for serotonin, commonly known as the happy hormone.
- It alleviates the symptoms of depression without causing the side effects often observed with conventional antidepressants.
- It works quickly after consumption, unlike traditional medicines which generally take several weeks to take effect.
CBD appears to be a promising natural solution for improving the state of mind of people suffering from depression.
In conclusion, CBD is a compound with many therapeutic virtues that can be used to alleviate various conditions such as rheumatism, osteoarthritis, multiple sclerosis, sleep disorders and depression , but it does not cure these disorders. Its analgesic, anti-inflammatory and mood-regulating properties make CBD a promising natural solution to these conditions.
The different forms of CBD
CBD oils
CBD oil extraction methods
There are several methods for extracting CBD oil from cannabis plants:
- Solvent extraction: This method uses liquid solvents such as ethanol, butane or isopropyl alcohol to dissolve and isolate the cannabinoids from the plant material. The resulting solution is then evaporated, leaving behind a CBD-concentrated oil. Solvent extraction is the least expensive method, but can leave harmful residues if all the solvent is not properly removed.
- Supercritical CO2 extraction: This method uses carbon dioxide (CO2) at very high pressure and temperature to extract cannabinoids from the plant. Once the pressure is released, the CO2 returns to its gaseous state, leaving no residue behind. Although this method is more costly and complex, it is considered the safest and most effective for obtaining high-quality CBD oil.
- Oil extraction: This method uses vegetable oils (such as olive or coconut oil) to extract the cannabinoids. The plant material is heated with the oil so that the active compounds are absorbed by it. Oil extraction is simple and can be performed at home, but the resulting oil generally has a lower CBD concentration.
Cannabinoid quality and temperature control
The quality of the cannabinoids depends largely on temperature control during CBD oil extraction. Too high a temperature can lead to cannabinoid degradation, while too low a temperature will not ensure optimal extraction.
Supercritical CO2 extraction is distinguished by its precise temperature control, resulting in a cannabinoid-rich oil of superior quality.
The importance of purification
Once the oil has been obtained, a purification step is essential to remove any impurities, such as traces of solvents, pesticide residues and microbiological contaminants.
Purification methods include filtration, short-path distillation and chromatography. Purified CBD oil guarantees a safe and effective product for consumers.
Recommended CBD oil dosage
There is no universal dosage for CBD oil, as each individual reacts differently to cannabinoids. Nevertheless, it is possible to establish a few guidelines for choosing the right dosage of CBD oil for your needs.
- Determining CBD concentration: CBD oil concentration is expressed in milligrams (mg) per millilitre (ml). It is important to know this information in order to correctly dose its use. Products with a low CBD concentration are generally intended for daily use and prevention, while those with a higher concentration are used for specific problems such as anxiety, pain or insomnia.
- Take weight and sensitivity into account: A person's weight influences the way they assimilate and metabolize active substances such as cannabinoids. For example, a lighter person will generally need less CBD than a heavier person to achieve the same effects. Individual sensitivity also plays a role; some people are naturally more resistant to cannabinoids than others.
- Start with a low dose and adjust: It's advisable to start with a small amount of CBD oil, then gradually adjust the dose according to the effects felt. The aim is to find the minimum effective dosage to reap the benefits of CBD without suffering any undesirable effects. A good starting point is to take 1 to 6 mg of CBD per 10 kg of body weight, then gradually increase if necessary.
Side effects
Although CBD is generally well tolerated, it can cause minor side effects such as drowsiness or gastrointestinal upset.
