There are many ways in which essential oils can have a protective action. Similar to the protective role they play in the plant (in many plants, the evaporation of essential oil from the surface has a protective role against the harmful effects of bacteria, fungi or other pests), they also protect us against bacteria, viruses, fungi, parasites, allergens, and toxins. After the first test conducted in 1887, hundreds other tests have been done to prove the effectiveness of essential oils against bacteria. All essential oils have antibacterial properties, but each oil is only effective against a certain type of bacteria. At the same time, although toxic to bacteria, most oils are completely harmless to the human body, the best example in this sense being tea bush oil. It also acts against Candida albicans – a fungus that causes thrush (oral mucosal infection) and against trichomonas vaginalis – a microorganism leading to vaginal infections.

An Indian study was published in 1971 proving that lemongrass oil is more effective against staphylococcus aureus than penicillin and especially when compared to streptomycin. Staphylococcus aureus is one of the micro-organisms that are most sensitive to essential oils. It most commonly spreads to infected wounds.

Valne personally confirms the findings of laboratory tests during the Second World War, when in his capacity as a military field surgeon he used solutions of essential oils as antiseptics in the treatment of fire injuries. In fact, essential oils were used for the same purpose in the seventeenth century. In his book Practical Aromatherapy, Valne quoted a case with a 31-year-old man treated for pulmonary tuberculosis in 1958. He was recommended to be a serious surgical intervention but he refused and instead he was subjected to intensive therapy, daily nasal sprays and aromatic enemas that proved to be effective, and after twelve years the check-up showed excellent health. Garlic essential oil is another powerful antiseptic used to treat tuberculosis. Many cases of successful cure of all kinds of infectious diseases with the help of aromatherapy can be cited, pioneers in this regard are a group of French doctors whose “secret weapon” is called an aromatogram.

We have already mentioned that rats, often touched by hands at an early age, have a more stable immune system than those who have been deprived of such a touch. Montague called this “very remarkable find”.
And the narrator Leon Haytov states: “There is strong evidence to boost immune function after relaxation through soft tissue massage.”

Obviously, both massage and essential oils on different pathways are able to increase the natural defenses of the body. It should be emphasized that it is very likely that this process is more effective in an individual who is relaxed during treatment. Here are all the elements of the aromatherapy procedure – massage, essential oils and relaxation. Any person in a “state of exhaustion” or predisposed to an infection would benefit from the immune stimulating effects of aromatherapy.
