The Most Common Terpenes and Their Effects: What Each One Does

Terpenes are the reason lavender calms you down, pine forests feel energising, and black pepper has that distinctive kick. These plant-derived compounds do far more than create pleasant aromas – they interact with your body in ways that can support sleep, ease discomfort, lift your mood, and more. If you've been exploring a terpene tonic soothe formula or wondering which terpene fits your wellness goal, this guide covers the key ones and what the science says.

Quick Answers:

• Terpenes are natural aromatic compounds found in plants, herbs, and fruits
  
  
• Each terpene has a distinct effect profile, from anti-inflammatory to sleep-supporting
  
  
• They work best when combined in a formulated blend (known as the entourage effect)
  
  
• Vasse Valley’s terpene tonic – soothe product targets pain and inflammation; others are designed for sleep, energy, or mood

What Are Terpenes?

Terpenes are organic molecules produced by nearly every plant on earth. They give pine trees their clean scent, citrus fruit its zing, and lavender its calming quality. Beyond fragrance, research increasingly shows these compounds have meaningful therapeutic properties – from anti-inflammatory and analgesic effects to anxiolytic (anti-anxiety) and sedative action. A comprehensive 2021 review published in Frontiers in Psychiatry identified terpenes as strong candidates for treating conditions including cognitive impairment, insomnia, anxiety, and depression.

There are hundreds of known terpenes, but a handful are well-studied and particularly useful for wellness applications.

Key Terpenes and Their Effects

Beta-Caryophyllene

Found in black pepper, cloves, and hemp, beta-caryophyllene is one of the most researched terpenes for physical discomfort. It's the only terpene known to directly interact with the body's CB2 receptors – part of the endocannabinoid system that regulates inflammation and pain. A broad review in PMC (Nutrients, 2020) documented its protective effects against chronic inflammation via NF-κB pathway suppression, reduced TNF-α, and significant antioxidant activity.

It's a core ingredient in our terpene tonic – soothe formula for good reason.

Alpha-Pinene

The sharp, clean scent of pine comes from alpha-pinene. It has anti-inflammatory properties and may support respiratory health by acting as a bronchodilator. It also shows promise for alertness and memory retention, which is why it appears alongside beta-caryophyllene in targeted pain-relief blends and energise formulas.

Research reviewed in Frontiers in Psychiatry (2021) found that alpha-pinene may increase cortical acetylcholine production — the neurotransmitter most depleted in Alzheimer's disease — and exert antioxidant effects in the hippocampus directly relevant to memory and attention.

Citral

Derived from lemongrass, lemon, and lime, citral is known for its antioxidant and anti-inflammatory properties. It helps reduce inflammation and may ease muscle soreness and joint discomfort. Like beta-caryophyllene, it's a strong candidate for terpene tonic – soothe applications.

Linalool

Linalool is the dominant terpene in lavender and is one of the most studied for sleep and anxiety support. It has calming, anxiolytic effects and may support natural sleep cycles without leaving you groggy the next morning. It features prominently in our well-formulated terpene for sleep and relaxation support.

A 2025 trial in the Journal of Clinical Sleep Medicine tested a terpene blend including linalool, myrcene, alpha-pinene, and beta-caryophyllene in 125 patients with insomnia, finding significant improvements in slow-wave and REM sleep architecture over 4 weeks.

Myrcene

Earthy and musky, myrcene is one of the most abundant terpenes found in plants. It's associated with relaxation and sedation, and research suggests it may enhance absorption of other compounds, making it a useful supporting terpene in sleep and recovery formulas.

Limonene

Limonene's bright citrus profile signals its effect – uplifting, energising, and mood-enhancing. It's been studied for its stress-reducing properties and its ability to support focus and mental clarity. It's a key terpene in our terpene tonic – energise formula.

A 2020 review in Evidence-Based Complementary Medicine confirmed limonene as one of the most active anxiolytic terpenoids, acting through CNS modulation of GABA and glutamate systems — studied in both aromatherapy and oral administration contexts.

Geraniol and Borneol

These two terpenes are less commonly discussed but relevant for hormonal and mood support. Geraniol has a floral, rose-like scent and shows anti-inflammatory and neuroprotective activity. Borneol has a cooling, minty quality with traditionally recognised calming properties.

How Terpene Blends Work

No single terpene works in isolation – it's the combination that matters. Terpene blends are formulated to target specific outcomes: pain and inflammation support (like Vasse Valley’s terpene tonic – soothe), natural sleep and relaxation support, energy and focus, or menopause and mood balancing. Each blend pairs terpenes whose effects complement one another, carried in a hemp seed oil base that supports absorption.

If you're new to terpenes, it's worth starting with the outcome you want and working backwards to the right blend. Most people notice meaningful results after two consistent weeks of daily use.

As with all supplements, consult your GP before starting, particularly if you're on prescription medications.
