CBD interacts with the body's own endocannabinoid system, which is responsible, among other things, for the regulation of sleep.

CBD oil is now almost indispensable in the wellness world. It is said to relieve headaches and menstrual cramps and also to promote more beautiful skin. But what can over-the-counter CBD oils really achieve?
More and more people are looking for ways to naturally enhance their well-being. CBD oil, an extract from the hemp plant, has established itself as a promising option in recent years, even touted by some as a cure. But how healthy is the remedy really and how can the quality of CBD oils be recognized?
Hemp contains over 100 cannabinoids – including the psychotropic THC and cannabidiol (CBD), which is not psychoactive. These are the two most therapeutically interesting ingredients in the cannabis plant: compared to THC, CBD does not cause a state of intoxication, but it has a number of other effects. As a result, CBD has attracted more and more attention in science in recent years, especially with regard to possible anti-inflammatory effects.
CBD oil, which is also often used in cosmetics, is obtained by extracting cannabidiol from industrial hemp and is then offered in various concentrations.
CBD interacts with the body's own endocannabinoid system, which is responsible for regulating sleep, pain sensation, immune system reactions, and mood. Because CBD interacts with the receptors of this system, it can cause various effects. There are indications for the following positive effects:
It is scientifically proven that CBD can reduce the frequency and severity of epileptic seizures.
Sublingual intake: For quick absorption through the oral mucosa, a few drops of CBD oil are placed under the tongue and held in the mouth for 30-60 seconds before swallowing.
Along with foods and drinks: If you don't like the taste of CBD oil, you can mix it into drinks and foods. However, the effect will be delayed.

The absorption of CBD oil is particularly effective through the oral mucosa.
Depending on the product, the concentration of CBD varies. Additionally, the optimal dosage varies from person to person and the intended use, always start with a low dosage. Broadly speaking:
For pain and inflammation: 15-20 mg CBD per day
For stress and anxiety: 10-15 mg CBD per day
For sleep disorders: 15-20 mg CBD about 30 minutes before bedtime
Since CBD – of good quality – is generally well tolerated and the range of possible positive effects is large, it is extremely attractive as a drug. However, some people may experience side effects such as diarrhea, fatigue, appetite changes, and also liver damage at high doses. Intake without medical recommendation is considered critical. Before use, a doctor should be consulted, especially if other medications are also being taken.
It is important to distinguish between approved CBD medicines and over-the-counter CBD products. Special caution is required because they can often look confusingly similar. While the ingredients of a medicine are pharmacologically clearly defined, this is not the case with over-the-counter products. The CBD content is not standardized here and, unlike CBD medicines, there is no safety monitoring by the drug authority.
Over-the-counter CBD products are sold as dietary supplements, mostly in the form of CBD oils. They thus belong to foodstuffs and are not subject to either the Cannabis Act or the Cannabis as Medicine Act.
The legal situation regarding CBD oils is complex and not entirely transparent. Because for dietary supplements with CBD, approval according to the EU Novel Food Regulation may be required, which often leads to problems in practice. Therefore, distribution is often chosen as "aroma oil, not intended for consumption."
