Molecular Wellbeing

Our expert aromacologists use cutting edge extraction technology to pin-point the most powerful plant molecules for our targeted essential oil formulas. We then boost our formulas with active ingredients, known as terpenes (aromatic compounds) which support healthy neurotransmission in the body. It’s this combination that creates the most high-impact wellbeing solution, known as whole plant therapy. Read more about terpenes and essential oil ingredients on our learn page.

Cold Pressed Borage

carrier oil

Also known as starflower, borage is one of Trelonk’s nutraceutical crops and has delicate purpley-blue star-shaped flowers – some say it’s even more beautiful than a field of Cornish bluebells and we happen to agree! Borage is a rich source of gamma-linolenic acid (GLA) and has a mulitude of uses. We have extracted and pressed the seeds and created this silky carrier oil, perfect for blending with our essential oils to create an advanced massage oil.

Cornish Farming and Chemistry Collides

Trelonk is a beautiful estate on the River Fal in the heart of Cornwall. Trelonk Farm has diversified its cropping approach, harnessing new technologies and sustainable farming practices to grow calendula and other specialist oil seed crops. This allows us to offer a truly innovative and environmentally responsible health and wellness product.

The estate has been farming for generations – and will be for many generations to come.

Science that makes scents

Have you ever thought why you can smell the bakery before you see it? Or smell the coffee and Danish pastries wafting down the high street? This is to do with the rapid pathway to the brain through the nose. Aroma particles are inhaled through the nasal passages where they meet the fine micro-nerve endings that are found at the top of the nasal cavity (around the bridge of the nose).
