You can already imagine the citrus zing of a lemon, the calming smell of lavender and the sharp freshness of pine (this one's popular, and outrageously abused by car fresheners). Those are terpenes, the naturally occurring compounds that give plants their distinct smells, and the hemp plant is full of them. So you already knew about terpenes, even if the word was new.
The entourage effect: more than just CBD
The entourage effect is an important idea in the CBD world. The premise: cannabinoids like CBD and THC work alongside terpenes and the plant's other compounds, and they seem to work better together than separated.
Broad-spectrum CBD products, like those we offer at unspun, are designed to preserve these natural compounds while filtering out THC. That means you get the potential benefits of the entourage effect, without the high.
Why terpenes could matter for how you feel
Terpenes may do more than smell good. Researchers have studied them for decades and each one may have effects of its own. These effects aren't certain and more clinical research is needed. But they're a good reason to care which terpenes make it into your bottle.
Lavender, citrus and pine: terpenes are behind every scent you know.
When people talk about calming teas, terpenes are often part of what they're pointing at: chamomile has bisabolol, lavender has linalool and even peppermint's menthol is a terpene.
You already know the 5 below by smell. Pay attention for a while and you may start to recognise them by how you feel too.
Limonene
Found in citrus peels, this terpene has a zesty aroma and is being studied for its potential mood-lifting effects.
Myrcene
Common in hops and mangoes, myrcene may contribute to relaxation and calm.
Linalool
The floral compound behind lavender's longstanding reputation for soothing and stress relief. It has some of the strongest research behind it, with several studies looking at its calming properties.
Pinene
With a fresh pine scent, pinene is being studied for its potential to support alertness and respiratory function.
Caryophyllene
This spicy, peppery terpene is the only one known to bind directly to the body's endocannabinoid system, the same network CBD interacts with.
The scent is only half of it. The other half is how you feel an hour later.
The way to find out is simple: take your CBD consistently for a few weeks and notice how you feel. Writing it down helps. Our piece on CBD journalling shows you how.
How to choose CBD with terpenes in mind
If you want the whole plant in your bottle, look for products that are:
✓ Broad or full spectrum, rather than isolate.
✓ Independently tested to confirm cannabinoid and terpene content. A brand should be able to show you the certificate of analysis.
✓ Extracted in a way that protects the plant compounds, whether that is CO₂ or cold pressing.
✓ Sourced from EU-grown hemp.
CBD isn't just about what it does. It's about how it makes you feel, and terpenes help shape that.
