Essential Oil Benefits

I love flowers and plants in general, so it stands to reason that when it comes to adding a fragrance to my soap then essential oils are the obvious choice. In fact, essential oils are the only way to add a natural fragrance to soap. 

The beauty of using essential oils in soap making is that not only do they add a gorgeous natural scent but in addition they add therapeutic benefits too.  

Aromatic plants and oils have been in use for thousands of years for many applications. In fact, the ‘father of medicine,’ Hippocrates, was known for prescribing perfumed fumigations for a variety of ailments. 

Although the study and use of plants has been around for thousands of years it was not until 1928 when the term aromatherapy was first used. The term was invented by Gattefosse, a French chemist who discovered by accident that lavender essential oil helped to heal a burn on his hand.     

The term aromatherapy can be somewhat misleading as it suggests the therapy is through sense of smell alone. In fact, there are three distinct modes of action on the human body: 

The pharmacological effect relates to the chemical changes which take place when essential oils enter our bloodstream and react with our hormones etc.

The physiological mode is concerned with the way an essential oil affects the systems of our body, so for example whether an oil relaxes or stimulates. 

The psychological effect takes place through our sense of smell and we respond to its fragrance.    


It is interesting to note that different essential oils are absorbed through the skin at different rates: 

  • Eucalyptus and thyme 20 to 40 minutes

  • Bergamot and lemon 40 to 60 minutes

  • Lavender and geranium 60 to 80 minutes

It is recommended that essential oils are used as external remedies only. They are highly concentrated oils and may potentially cause damage if taken internally. Only a small amount of essential oil is needed to enjoy the therapeutic benefits. For example, one or two drops in a base oil for massage.

In soap making an essential oil or a blend of essential oils can be added to your overall recipe at a maximum rate of 3%. For example, if you are making soap with a total combined weight of 500g of base oils (such as olive oil, coconut oil and sunflower oil) then the maximum weight for adding an essential oil or a blend in this recipe is 15g which is 3% of 500g.


How Essential Oils Work

The therapeutic potential of essential oils has yet to be fully realised. Plant remedies are extremely powerful and are more fully understood and utilised by indigenous people such as the Native Americans. For example, Native American tribes consider Rosemary to be sacred. They use it for mainly for relieving sore joints.

You may already be aware that many active plant compounds form the basis for most of our modern drugs such as quinine and cocaine. But we still have so much to learn about plants and the ways that they can help us and yet sadly many are under threat from extinction.

 

The Skin  

Essential oils provide a range of benefits to skin and are very versatile as they can address a wide variety of skin issues. The following benefits are provided:

Antiseptic for cuts, bites, spots etc. For example, tea tree, lavender, and lemon.

Anti-inflammatory oils for eczema, infected wounds, bumps, bruises etc. For example, German and Roman chamomile and lavender.

Fungicidal oils for candida, ringworm, athletes foot etc. For example, lavender, tea tree and patchouli.

Healing for burns, cuts, stretch marks etc. For example, lavender, chamomile, rose and geranium.

Deodorants for excessive perspiration. For example, bergamot, lavender, and lemongrass.

Insect repellents for lice, ticks, mosquitos etc. For example, lavender, citronella, eucalyptus and cedarwood.

 

The Respiratory System

Nose, throat, and lung infections respond very well to treatment with essential oils. Inhalation is a highly effective way of utilising their benefits. Whenever I have blocked sinuses eucalyptus essential oil always provides much relief and it is better than any other remedies I have ever tried. Peppermint essential oil is also effective to relieve blocked noses, colds, and catarrh.


The Digestive System

Essential oils should not be taken internally as they are too concentrated. External application can effect changes in the digestive process. For example, peppermint can help with indigestion and ginger can help with nausea.


The Endocrine System

Essential oils can influence our hormones and indeed some oils contain plant hormones which mimic the corresponding human hormones. Plant oestrogens are perhaps the most well known and help to maintain a healthy circulation, good muscle, and skin tone.


The Immune System  

Nearly all essential oils have bactericidal properties which helps protect against colds and flu. Essential oils also promote the production of white blood cells which help the body fight infection and other diseases. A few immune system boosters include basil, eucalyptus, lavender, rosemary, and tea tree.


The Nervous System

The properties of essential oils on the nervous system are twofold. They can either act as a sedative and the most well-known for this is lavender. It is relaxing and improves sleep. On the opposite side plant oils such as peppermint can act as a stimulant. 


The Mind

Discussion around the effect that essential oils can have on psychological and emotional responses is extremely popular. I find this one of the most fascinating areas of application - the benefits for our mind. And it is the least understood area of activity of essential oils. One important consideration to note is that the psychological impacts will differ from one person to another. And there are a variety of factors at play including circumstances, mood, and previous associations. People will respond to fragrances in different ways.


Blending Essential Oils

In soap making single essential oils can be used in recipes although be wary of citrus oils like orange and lemon because they are more delicate and may not survive the saponification process as well. In which case you should blend these oils. The main purpose of blending essential oils is to create a perfume. A blend of essential oils will also bring different therapeutic values to a product. For example, a blend can have a therapeutic action on a physical condition and at the same time can have an affect at an emotional level. It is for this reason that essential oils are so powerful.

Essential oils are categorised according to the notes in music scales. This was the idea of a French man called Piesse who introduced the system in the nineteenth century. When creating blends, a good rule of thumb is to select an essential oil from each one of the following categories:

The top note is immediately apparent due to the fast evaporation rate. For example, lemongrass.

The middle note is the heart of the fragrance and most essential oils fall into this category. For example, lavender.

The base note is an intense and heavy scent that can anchor a blend. For example, cedarwood.
