How Aromatherapy Works

 Most people do not realize that essential oils which are the basis of aromatherapy enter the blood stream of the body via skin absorption or inhalation and act as catalysts to create balance in the cells and organs.

This is a simplified journey with a molecule of essential oil through the body:

  • ~To begin, the molecules of oil are small due to the distillation process. Their small size and the polarity determine how fast the oil molecule will penetrate through the outer layer of skin, the epidermis. They often go through via a hair follicle or sweat gland. The oil molecule then travels to the dermis and enters the blood capillaries there. Eventually it passes to the arteries and veins throughout the body. As the oil molecule moves through the blood stream, it finds the right cell receptor for binding. For example, a molecule of Rosemary travels to cell receptors on the liver. Finding the right cell receptor, it acts to regenerate and balance this vital organ. The oil molecule will leave the body in 4 to 24 hours. Usually, it is processed by the liver to become water-soluble. It then moves out of the body through the kidneys into the urine. This is an amazing gift from God that we have been bestowed. To imagine and realize that essential oils are so smart in frequency that they can find the correct cell receptor that needs its qualities of healing surpasses any lab created medicine.


Skin absorption factors:

  • ~Skin Hydration - A hot bath or shower can increase the absorption of essential oils.
  • ~Occlusions - Covering the skin with clothes, bandages etc. will increase the temperature and absorption of essential oils
  • ~Temperature - Warmth of air or water increases blood capillary circulation and absorption of essential oils. Heat due to exercise increases absorption also.


Olfactory: the inhalation of Essential oils:

 The other main path for essential oils to enter the body is through the olfactory system. As a person inhales the essential oil, the molecule of oil goes up into the back of each nostril to the postage size Epithelium patch. The molecules attach to receptors on the cilia hairs in the nose space. They turn into nerves on the other side of the mucous patch, which sends the odor info on to the olfactory bulb. This means the essential oil itself is not sent to the brain, but instead a neural translation of the complex essential oils. The millions of nerves enter through the bone to the olfactory bulb and merge into two large nerves that go back to the limbic brain in the inner center of the head. The right nerve goes back to the Amygdala, a center for emotions in the limbic system. There the aromatic info is connected to the emotions of the situation.

 Because the limbic system is directly connected to parts of the brain that control heart rate, blood pressure, breathing, memory, stress levels, and hormone balance, scents can have physiological and psychological effects.  
Essential oils are also absorbed through the skin when directly applied, such as with massage. They then travel into the lymphatic system, which circulates them into the blood stream, where again they can have physiological effects.

 For example, a person smells a bouquet of fragrant roses and suddenly receives traumatic news; they will always have an uneasy feeling about the smell of these flowers. The opposite effect is true as well, if one were expressing fresh squeezed orange juice and surprised by their partner with acts of affection, they will smile inwardly every time they smell oranges.

 The nerve information is sent on from the Amygdala to the Hippocampus, a center for short term memory in the Limbic system. So, right away, the smell, emotion, and memory are commingled, as they are stored in the Limbic system. Then this information goes on to the Hypothalamus for long-term memory. It is passed on to the Pituitary or master gland and eventually the whole endocrine system.

There are a variety of companies that sell essential oils. Knowing the reputable ones from the bandwagon ones takes knowledge and further research.


As an professional Aromatherapist, there are several factors I must inquire before purchasing essential oils.

  1. knowing the date of distillation is extremely important as some essential oils begin to lose their therapeutic value and have approximately `1-2 years of shelf life.
  2. I always ask for the GC/MS fore each oil of purchase as this gives me the exact constituents that are comprised in a specific batch of essential oil.
  3. Knowing the conditions in which the oil was grown also lends to the constituent value of a specific oil.

Now with these unique factors in place, your average consumer would not be privy to this information nor would they know how to analyze it.  It is my belief that if you want an oil that smells good to freshen your environment, go ahead and purchase it from your local health food store.

There is no way of knowing how long that product has been on the shelf nor can you know if it was adulterated in the extraction process. Unfortunately there are companies that add chemicals or other ingredients to a specific batch of essential oil to "stretch" the yield.  Again, to the average consumer, your nose might not pick up on this.
