“Blending essential oils is both a science and an art. When oils are thoughtfully paired, they create aromatic layers that can calm, uplift, or clarify the mind.”
- Cheryl Gan, Founder and Managing Director of HYSSES, Barn & Potter Manufacturing, and 365Days.

Can You Mix Lavender and Lemongrass Essential Oils?

At first, Lavender and Lemongrass may seem like an unusual pairing, one soft and floral, the other bright and citrusy. Yet, they harmonise beautifully, balancing calm with clarity.

• Lavender Essential Oil is known for its soothing, balancing, and skin-calming properties. Traditionally used to support sleep, ease tension, and create peaceful spaces.

• Lemongrass Essential Oil carries a fresh, lemony, herbaceous aroma that refreshes the mind, uplifts mood, and offers natural antibacterial support.

When blended, the result is both grounding and energising, perfect for modern spaces that need calm focus.

How to Use the Lavender–Lemongrass Blend

• Aromatherapy: Add 3 drops Lavender + 2 drops Lemongrass to a Hysses Nebuliser or ultrasonic diffuser to refresh the air and ease tension.

• Topical: Dilute the blend with a carrier oil for skincare. Lavender soothes the skin while Lemongrass tones and purifies, ideal for oily or acne-prone skin.

• Natural Room Spray: Combine with distilled water and a splash of witch hazel for a quick linen mist or air freshener.

According to a 2020 study published in the Journal of Applied Microbiology, essential oils like Lemongrass exhibit notable antibacterial activity against common airborne microbes, making them valuable additions to indoor environments.

Safety Tip: Always dilute essential oils before skin application and perform a patch test. Lemongrass can be strong for sensitive skin types. Avoid direct eye contact and never ingest essential oils unless advised by a qualified professional.

How to Diffuse Essential Oils in Your Car

Transform your daily commute into a calming or energising ritual with essential oils. Whether you need alertness on early drives or serenity in traffic, diffusion methods are simple:

• Vent Clip Diffusers: Attach to your air vent for consistent scent distribution.

• USB Mini Diffusers: Ideal for longer trips.

• DIY Options: Place a few drops on a cotton ball or wooden bead near a vent.

Recommended Oils for the Car

A 2022 Harvard Health review found that short-term inhalation of peppermint oil improved alertness and decreased fatigue during driving simulations.

Why Dilution Matters

Essential oils are highly concentrated. Undiluted use can cause irritation or sensitisation. Diluting with a carrier oil ensures safe absorption and prolongs your blends.

Carrier Oils Commonly Used

• Jojoba Oil: Absorbs quickly, mimics natural sebum, ideal for facial blends.

• Sweet Almond Oil: Rich in vitamin E, nourishing for dry or sensitive skin.

• Fractionated Coconut Oil: Lightweight, antimicrobial, perfect for rollers and body care.
