Tea Tree Essential Oil

History
Indigenous people of northern New South Wales in Australia have been using the healing properties of the tea tree oil for millennia.
The following methods were used to release the essential oils in the leaves to benefit respiratory ailments and cuts and wounds.
1.     Leaves were crushed to release the aroma that was then inhaled
2.     Rocks heated in a fire were placed in the creek; leaves would be placed in the resulting steam that would release the oils3.
3.     Crushed leaves were applied as poultices to help heal cut and wounds1.

Recent history
It is thought that the name originated from Captain Cook’s description of one of these shrubs as he saw local indigenous people brew leaves to make an infusion to drink instead of tea2.

It is only after World War I that scientists began to seriously study the application and use of tea tree with Arthur Penfold, a leading chemist, discovering its potency, which was 12 times higher than carbolic acid, the used remedy at the time.

In the 1930’s and 1940’s tea tree was seen as the near perfect antiseptic. Demand grew which meant that producers and cutters were exempt from military service until enough tea tree essential oil was gathered. Australian soldiers carried it in their first aid kits during World War II as it was safe to apply neat to prevent infection, help with tinea and repel insects.

With the advent of synthetic antibiotics - cheaper and easier to develop in larger quantities though less effective - tea tree was forgotten with the industry collapsing. It resurfaced however in the mid 70’s with Eric White convinced that tea tree had a place in modern society and he successfully created Thursday Plantation1 2.

Origins of Tea Tree
Tea tree is an Australian native. In New South Wales, Australia, Lake Ainsworth has the colour of tea from the surrounding tea trees. The Bundjalung aborigines swam there to heal any sores, wounds or skin problems. Today the tea tree is carefully cultivated in plantations2.

Benefits
Tea tree has many benefits from stopping the bleeding of gums to neat application on cuts and wounds to vaginal suppositories.
This powerful essential oil has been found effective in eradicating fungi and yeast infections such as infected feet, tinea in the nails and candida. It also has applications for the scalp where it gets rid of dandruff, prevents head lice and clears the scalp of dead skin. Added to toothpaste, it controls bacteria thus maintaining good oral health. Dabbed on acne, it kills the responsible bacteria and scientific studies have shown the oil has proved capable of dispersing infectious material and debris trapped within wounds”2

Research is still taking place uncovering more and more benefits of this amazing oil.

Sleep and Aromatherapy

Definition of sleep
The dictionary defines sleep as: “a condition of body and mind which typically recurs for several hours every night, in which the nervous system is inactive, the eyes closed, the postural muscles relaxed, and consciousness practically suspended.”

Sleep variations
It is impossible for individuals to give a detailed analysis of their sleep as they are, yes, you guessed it: asleep!1 There are many variations on sleep quality. Often we hear the following:
    did not sleep well because of too many dreams! 
    slept deeply but felt tired when arising
    sleeping in bursts, waking but feeling fine (or not) in the morning.


Effects of not sleeping well
There are negative consequences following a night of inadequate or broken sleep. It is more difficult to absorb new information, concentration is not as sharp as it could be and our judgement and moods are affected. Safety is put at risk as reaction times are much slower when operating equipment. Driving a car in a state of fatigue has been compared to driving when drunk.



Effects of a good sleep
“Good sleep is possibly the best natural medicine in existence”. Scientific studies show that sleep plays a critical role in keeping us healthy, all bodily functions slow down and remain highly regular and stress free. Being well rested boosts our immune system and metabolism and may decrease the risk of health problems such as obesity, heart disease and diabetes1.

Our sense of smell
The following is a very very brief explanation on our sense of smell. Inhaled essential oils dissolve in the mucus that is present in the nostrils, this then reaches the olfactory system that stimulates nerves that transmit the message to the olfactory bulb into the limbic system.  There, the amygdala plays a big role in the memory of smells and the storage of emotion - happiness, depression, grief, etc. Smell sensations are relayed to the brain hemispheres where cognitive recognition occurs after the limbic brain has been stimulated. This is when we recognise smells, which have motivational and emotional influences on us.

Some smells may make us feel uncomfortable and may even make us feel sick. A pleasant smell however will lift our mood and make us feel positive. As essential oils reach the limbic system, neurochemicals and hormones are released that affect the body’s functions such as   boosting the immune system. Some essential oil components have a calming and sedative effect on the brain and slow the heart rate both through inhalation and through massage2.

A great blend of high quality essential oils that induces sleep, it combines essential oils that relieve stress, are calming and sedative and help the brain and body to relax. Users have reported an improved quality of sleep - deeper, longer and more restful. An elderly user discovered it helped dissipate unpleasant dreams.

Conclusion
Improved sleep patterns have a positive effect on general health and wellbeing.
