Cannabigerol (CBG) is often called the “mother cannabinoid”, because its acidic form is the starting compound from which the plant makes the other cannabinoids. In recent years it has appeared on many labels, often accompanied by promises that research does not support.
Origin
In the plant, cannabigerolic acid (CBGA) is converted by specific enzymes into THCA, CBDA and CBCA. That is why little CBG usually remains in mature hemp, and products rich in CBG require selected varieties or special processes.
CBG and CBD compared
| — | CBG | CBD |
|---|---|---|
| Psychoactivity | Not reported | No |
| Amount in the mature plant | Usually low | The main constituent of industrial hemp |
| Human studies | Very few and small | Numerous, including an approved medicine |
| Approved medicines | None | Epidyolex, only for rare forms of epilepsy |
What the research says
- Most research has been carried out on cells and animals.
- There is almost no research in humans: for example, a 2024 study (Cuttler et al., Scientific Reports) involving a single dose in healthy adults, which measured subjective ratings in a laboratory. One small, short study does not allow conclusions to be drawn.
- There are no clinical trials demonstrating effects of CBG on any disease.
How to read the label
As with CBD, what matters are the milligrams of each cannabinoid per volume and the batch certificate of analysis, which must state the measured CBG value. If there is none, the declared amount cannot be verified.
What we actually sell
Hemp oils: strengths from 5% to 50%, full spectrum extract, an analytical report for every batch. The composition is described on the CBD oil page and in the shop. Our products are not medicines, and we do not attribute to them any property of preventing, alleviating or treating disease — in accordance with Regulation (EC) No 1924/2006.
Frequently asked questions
What is CBG?
Cannabigerol, a hemp cannabinoid whose acidic form is the precursor of the other cannabinoids.
Is CBG psychoactive?
Psychoactive effects have not been reported, but research in humans is very limited.
Are there clinical trials of CBG?
Very few, and they are small; none demonstrates effects on disease.
How can I check how much CBG a product contains?
Through the batch certificate of analysis showing the measured value.
