What is CBD Oil? – A Complete Guide to Cannabidiol

Updated April 2026 · 10 min read

CBD oil has grown in popularity across Europe and beyond. But what exactly is CBD, how does it work in the body, and is it legal? In this article, we cover everything you need to know.

What is CBD?

CBD (cannabidiol) is one of over 100 cannabinoids found naturally in the hemp plant. Unlike THC, CBD has no intoxicating effects. CBD oil is made by extracting CBD from hemp and diluting it in a carrier oil, typically MCT oil.

The Endocannabinoid System (ECS)

The body has its own endocannabinoid system (ECS) involved in regulating a range of bodily functions:

• Pain perception and inflammatory responses

• Sleep quality and circadian rhythm

• Stress response and emotional balance

• Immune function and cell protection

Full-Spectrum vs. Isolate

Full-spectrum CBD oil contains all of the plant's natural cannabinoids, terpenes and flavonoids, which work together in the so-called "entourage effect". Research suggests this combination may be more effective than CBD isolate alone. Pharmadrops uses full-spectrum hemp extract.
