10 Surprising Facts About Essential Oils You Probably Didn’t Know
Essential oils have been treasured for centuries for their natural healing properties, aromatic appeal, and spiritual significance. From Cleopatra’s beauty rituals to modern-day aromatherapy, these concentrated plant extracts continue to captivate people around the world. Yet, beyond their soothing scents and therapeutic allure lies a world of fascinating facts that most people don’t know.
Whether you use oils for relaxation, skincare, or household cleaning, there’s more to them than meets the eye—or nose. Many people assume that oils are simply fragrant extracts, but they are actually complex compounds with powerful biological and chemical properties. The science behind how they affect our body and mind is both intriguing and surprising. In this blog, we’ll uncover 10 surprising facts about oils that will change the way you look at these potent natural elixirs.
Essential Oils Are Not Actually “Oily”
Despite their name, essential oils aren’t really oils in the conventional sense. Unlike cooking oils or carrier oils, they don’t contain fatty acids. Instead, they are highly concentrated plant compounds extracted through methods like steam distillation or cold pressing. This is why essential oils evaporate quickly when exposed to air and don’t leave a greasy residue. Their “oil” label simply refers to their hydrophobic nature—they don’t mix with water but blend well with carrier oils or alcohol.
It Takes a Huge Amount of Plants to Make a Small Bottle
One of the most surprising things about essential oils is how much plant material is needed to produce just a small amount. For instance, it takes around 60,000 roses to make one ounce of rose oil, and roughly 250 pounds of lavender flowers to make one pound of lavender essential oil. This explains why certain essential oils are more expensive—they are literally the most concentrated form of nature’s goodness.
Essential Oils Can Influence Brain Chemistry
When you inhale an essential oil, its molecules travel directly to the olfactory system and connect with the limbic system—the part of your brain responsible for emotions, memory, and behaviour. This is why certain scents can trigger memories or affect mood almost instantly. For example, lavender is known to promote relaxation, while peppermint can increase alertness. This direct connection between scent and brain chemistry is what makes aromatherapy so powerful in managing stress and anxiety.
Not All Essential Oils Are Safe for Direct Skin Application
Many people assume that because essential oils are natural, they’re automatically safe to use directly on the skin. However, some oils—like cinnamon, oregano, and clove—are highly potent and can cause irritation or allergic reactions if not diluted properly. It’s always best to mix them with a carrier oil like coconut or jojoba oil before applying. Even seemingly gentle oils like tea tree or lavender should be patch-tested before use.
Essential Oils Have Natural Antibacterial and Antiviral Properties
Before antibiotics were invented, purity essential oils were widely used for their antimicrobial properties. Modern research supports their efficacy: tea tree oil, eucalyptus, and thyme oil are known to combat bacteria, viruses, and fungi. In fact, during the Black Plague, grave robbers reportedly used a blend of clove, lemon, cinnamon, and rosemary oils to protect themselves from infection—a formula now popularised as “Thieves Oil.”
The Scent of an Essential Oil Can Change Your Heart Rate
Scientific studies have shown that certain essential oils can physiologically alter your heart rate and blood pressure. For example, inhaling ylang-ylang can help lower blood pressure and slow the heart rate, while peppermint can do the opposite—boosting alertness and increasing pulse rate. This fascinating connection between scent and cardiovascular response demonstrates how aromatherapy isn’t just psychological but also physical.
Ancient Civilisations Were the First to Use Essential Oils
Essential oils aren’t a modern discovery. The ancient Egyptians, Greeks, Romans, and Chinese used aromatic plant extracts in religious rituals, medicine, and beauty routines thousands of years ago. Egyptian tombs dating back to 3000 B.C. have been found with jars of essential oils such as frankincense and myrrh. These civilisations understood the healing power of plants long before modern science validated it.
Essential Oils Can Repel Insects Naturally
Essential oils are an eco-friendly alternative to chemical-based insect repellents. Citronella, eucalyptus, lemongrass, and peppermint oils are effective in keeping mosquitoes and flies at bay. Unlike conventional repellents, they’re non-toxic, smell pleasant, and can even be used safely around children and pets when properly diluted. This makes them an excellent choice for anyone looking for a natural way to protect against insects.
The Quality of Essential Oils Depends on How They’re Extracted
Not all pure essential oils are created equal. The extraction process significantly influences their purity, potency, and aroma. Steam distillation and cold pressing are the most common methods used to preserve the active compounds. However, some cheaper brands use chemical solvents, which can leave harmful residues behind. Always look for 100% pure, therapeutic-grade essential oils that are extracted naturally and tested for quality.
Essential Oils Can Be Used for More Than Just Aromatherapy
While most people associate essential oils with relaxation and massage, their uses extend far beyond that. They can be incorporated into skincare routines, natural cleaning solutions, hair care, and even cooking (provided they are food-grade). Lemon, for example, is a natural degreaser and air purifier; lavender can be used in homemade bath salts; and peppermint oil can freshen up toothpaste or mouthwash. Their versatility makes them a holistic addition to both wellness and household care.
