In another study by Brum et al. 2002, they showed how linalool as in Lavender
(Lavandula angustifolia) and Ylang ylang (Cananga odorata) has sedative effects on neuronal
function by antagonism of the receptors of NMDA (another neurotransmitter).) Since these two
studies show how essential oils can block neurotransmitter receptor sites, perhaps with more
study, we will find the oils also make it harder for a virus to get into a cell by blocking viral
receptors.
Essential oils have psychoemotional benefits also. For example, a study by S. Wilkinson
in 1999 on 103 cancer patients in a palliative care setting found massage with Roman Chamomile
(Chamaemelum nobile) reduced levels of anxiety and improved physical and psychological
symptoms of patients. (Wilkinson S., 1999 Palliative Medicine) Professor Rovesti of Milan in
1973 focused his research on essential oils and emotions. He found they curbed many negative
instincts and brought relaxed alertness (an ideal state).
We live in a time of great stress, and this plays havoc with the interaction between our
body's immune, endocrine, and digestive systems. Having a strong immune reaction is the best
defense against viruses. Often a poor immune response of the phagocytes, which are a first line
defense, is caused by a sluggish digestive system. Eating a more alkaline diet of fresh fruits,
vegetables, and grains gives the body enzymes, vitamins, and minerals, plus fiber for flowing
elimination. This gives the immune system a boast. Have you ever noticed how a viral cold will
start after an emotional upset and eating heavy acid foods (such as fast foods)? An essential oil
blend that facilitates digestion is:
Coriander (Coriandrum sativum) It has a large amount of terpene
alcohols (Linalool is 61%) with some coumarins. It tonifies and benefits the
whole digestive system. It inspires confidence with a mild euphoric effect
for a tired, tense mind.
Ginger (Zingiber officinale) An oil rich in sesquiterpenes. Its properties ease flu infections,
stimulate circulation, and calm digestive problems. It is cheering emotionally and acts as a nerve
tonic.
Cardamom (Elettaria cardamomum) A complex oil with monoterpenes, 1,8 cineole, 26%,
esters terpinyl acetate 44%, aldehydes, and sesquiterpenols. It has a warming action as a laxative
and digestive aid. It uplifts a tired mind and clears negative confusion.
The virus cannot make headway in such a healthy environment.
To examine the immune and endocrine system interaction, let us look at the ACTH loop,
an interesting mind-body loop. Here is a prime example where emotions impede the flow of
peptides and this elicits hormones in a deadly loop. It begins with upset emotions and depressed
thinking which triggers the release of CRF, peptide of negative expectations, from the
hypothalamus. CRF (cortical releasing factor) is found at 10 times the normal level in the
cerebrospinal fluid of people who have committed suicide. CRF is secreted by axons, which
travel to the anterior pituitary gland to release ACTH (Adrenocorticotropic) hormone. This
hormone travels through the blood stream to the adrenal glands where it binds with receptors. The
adrenal cortex creates steroids, called cortisol, a substance necessary for healing and damage
control when an injury occurs. Stress and lack of sleep increase steroid production.
Cortisol is being discussed today in ads due to its action of causing weight gain.
However, its most serious effects are suppressing the immune system and increasing heart and
blood pressure. A study by Alan Watkins in 1994 Mind-body Medicine found that negative
thoughts suppress T cell and macrophage action. As cortisol decreases the T helper cells and
natural killer cells, viral infections become more frequent. This leads to depressed behavior,
moods, and thinking, so the cycle begins again. We have all experienced it to a certain extent. It
