Methods of Application and Absorption of Essential Oils

There are several ways through which essential oils can be absorbed in to the human body. They are usually diluted before being introduced in to the body in order to reduce their concentration since they are normally very strong in their natural state. They are applied in small quantities per session. They are usually diluted with cream or oil especially for massage sessions. The essential oils are composed of small molecules that can be quickly absorbed in to the body through the skin. Some of them easily penetrate the skin layers to get to the blood stream. Substantial amounts of oils gain entry in to the blood stream through this method. They usually get in to the blood stream through diffusion. This is facilitated by the inability of the skin to bar fat soluble compounds from passing through it in to the blood stream (Churchill Livingstone 2008 pp. 112-114).

The normal respiratory process in a human body usually takes place through diffusion. When oxygen gets in to the lungs from the air, it diffuses in to the blood stream from where it circulates throughout the body. The same case happens to the aromatherapy treatments that involve inhaling the essential oils in form of steam or perfume. Once sprayed in the air surrounding the nostrils, the steam or perfume is inhaled and absorbed through the lungs in to the blood stream. The disinfecting ability of the perfumes is significant in the improvement of breathing after disinfecting the air from pathogens that may cause problems to the respiratory system. The nose is of utmost importance in the detection of essential oils that is absorbed in to the body through inhalation. The sense of smell is generally accepted as the most efficient means of detecting the means through which essential oils access the body. It has an express connection with the brain thereby changing the chemical structure of the smell of the essential oils inside the nose and transmits the information into the brain, resulting in a variety of effects after the brain transmits electrochemical impulses to the receptor cells.

Effects of aromatherapy

Aromatherapy has a variety of effects on the human body. This mainly depends on the quality and effects of the oils that are used for treatment. They are usually physical and psychological.

Some absorb water from the surface of the skin while others moisturize it. For the purpose of pain relief, the oils are applied physically and therefore can result in multiple effects on the body.

In addition to therapeutic effects, aromatherapy is also a source of beauty. Essential oils have anti-fungal and anti-bacterial properties that protect the skin from the action of bacteria that may be attached on the skin causing skin rash and pimples. The natural fragrance helps to boost the moods of a person once inhaled because in their gaseous state, they tend to affect the mind. Due to the uniqueness of emotional centers of the brain in storing information, the smell of different essential oils makes many people to experience a particular awakening of long time memories whether favorable or unfavorable. In such a case, people who have suffered situations of memory loss are able to remember some of the important circumstances which may otherwise be forgotten. The placebo effect is a significant form of treatment in the human body. It is usually derived from essential oils. It is usually felt in the body to a large extent compared to the other methods of cure. It boosts the body’s self healing system (Brenda Mullingerb 2008).

Aromatherapy is one significant way of improving the standards of living. It helps in providing the human body from ailments that may be caused by environmental stress or day to day chores.
