What is CBD oil?

In just a few years, CBD has gone from something unknown to most of the general public to one of the most popular cannabinoids.
This increase in knowledge now gives users a number of different ways to use this cannabinoid, with CBD oil administration being a popular option. The use of this cannabinoid orally is the simplest and most direct way to consume the molecule, as well as the easiest way to control the dosage.

The high demand for CBD oil is largely due to the effect it has on fighting anxiety, stress or fatigue problems, acting directly to improve your rest. However, its popularity could also lead to more misinformation about CBD.


In order to understand how CBD oil works, we need to bear in mind that there are two types of Cannabinoid Receptors (CB) in our bodies, because that’s where CBD will work.

CB1, which is found in the lower and upper limbs and also acts on the brain and stomach. And CB2, which is found in the intestines, the heart and also in the bones.

With the intervention of this cannabinoid, CB1 prevents excess neuronal activity, helping with relaxation and reducing anxiety. It can also help with memory issues and even have a positive influence on cognitive ability and concentration. In the case of CB2, it will be important in the response against inflammatory and infectious systems.

In short, we can conclude that CBD oil is an excellent “general controller” of our entire system, making it more balanced and efficient, both physically and mentally.


As mentioned above, CBD oil allows the human being to enter into balance. It can also be very important in the prevention and treatment of certain health problems, such as stress, fatigue, cancer or epilepsy.

Although we are talking about lengthy and ongoing research, it has already been possible to conclude the existence of analgesic and anti-inflammatory properties in CBD products.

Let’s look at two very common health problems:

CANCER – There has been some research into the efficacy of CBD in cancer problems. The authors of an article published in a renowned journal of Clinical Pharmacology have found some evidence that this cannabinoid prevents cancer cells from growing and spreading, and also promotes their destruction. CBD could be a good means of prevention and an excellent tool against the spread of cancer, but studies are still being carried out to obtain more concrete results on the effectiveness of this method. cannabinoid in problems with carcinogenic content.

STRESS – According to the WHO it has been proven that CBD oil, in addition to having no psychotropic effects, has a unique and positive effect on stress-related problems. It is in this field that CBD can act, because it can do so in different areas such as mood or sleep quality, thus reducing stress levels in the human body and reducing the likelihood of these situations happening again.


It is a fact that in very sporadic cases CBD oil can have some side effects, but we must always understand that each human being is unique, so we must always be aware of some of the possible results of consuming CBD oil. One of the symptoms in which you may start to feel some side effects is tiredness. In these cases, the daily dose should always be adjusted to the person concerned, which is why it is always recommended to use small doses when starting consumption.

Other possible side effects are dry mouth, diarrhea or low blood pressure. If you are already taking other medications, it is always advisable to consult your family doctor before starting CBD Oil.

It should also be emphasized that oil made with this cannabinoid shows no signs of being addictive , according to the WHO, as they maintain that CBD is well tolerated by our immune system and therefore has a good safety profile.


With an increasingly vast and competitive market, it’s only natural that more and more CBD products, in this case oils, are appearing. You should look out for some signs that could be good indicators of quality oil or a lack of it:

PORTION OF THC PRESENTEDCBD oils made from hemp can contain low amounts of THC, a figure that should be around 0.2% or less. However, some errors in processing can cause THC levels to increase to the point of transmitting psychotropic effects, which is automatically a sign of the product’s poor quality and can also make it illegal.

Extraction using CO2 in a supercritical state – Always avoid CBD oils that use chemicals such as butane or propane in their extraction, as these are of lower quality and can leave dangerous contaminant traces. Always look for safe solvents such as supercritical CO2 to extract CBD, as this not only guarantees a safer extract but also significantly reduces possible environmental damage.

QUANTITY OF CBD – At the time of purchase, we should always analyze the relationship between the concentration of CBD and the volume of the package, and higher numbers will automatically mean a more intense experience. The recommended dose is always between 250-1000 grams of CBD per package.

TAKE EXTRACTS FROM THE WHOLE PLANT AND NOT FROM CBD ISOLATES – The CBD oils produced from the whole plant are known as full-spectrum oils and generally have a higher quality than oils made from isolates of the plant. CBD. Despite the isolates presenting the purest form of CBDThese have a shortage of Terpenes and Flavonoids which works in partnership with the CBD. When these elements work together, they are more effective, which is why we consider full-spectrum extracts to be a determining factor when assessing the quality of a CBD oil.


In Portugal and several European countries, CBD oil is considered legal and is available without a prescription, as long as it has a THC content of less than 0.2%. Although CBD Oil is considered legal, each country’s local regulations on its cannabinoid content may vary, so you should always check with your local authorities if you want to take your CBD Oil with you on a trip.
