Antibacterial Essential Oils: Natural Alternatives for Antibiotic Drugs

This post is particularly based on antibacterial essential oils, including their composition and uses. Essential oils are natural products that are made of several volatile compounds. You can also refer to these oils as products attained from raw plant materials by steam distillation, dry distillation, or hydro-distillation.

The description of these oils excludes other volatile produces acquired by diverse extractive techniques, such as supercritical fluid extraction. Most natural oils have similar therapeutic properties, such as antibacterial, anti-inflammatory, antiseptic, antispasmodic, analgesic, sedative, and antimicrobial among others.

The Antibiotic Alternative

A good number of studies have reported interactions between antibiotics and essential oils. Many of these oils have proven effective against bacteria, and others fight infection with amazing efficiency. A large percentage of the oils lower the pH of your blood, creating an unwelcoming environment for bacteria. Unlike the usual antibiotic drugs, which may cause adverse side effects, natural oils are probiotic. Apart from eliminating pathogen bacteria, they also leave beneficial bacteria intact.

Most bacteria tend to form some kind of resistance to usual medication, but they are incapable of doing so with essential oils. Scientists as well as farmers are faced with an ever increasing problem of drug-resistant bacteria. As antibiotics continue to lose their effectiveness, scientists have undertaken more studies on herbs, and their essential oils. They have considered herbs and natural oils because they have highly complex chemical structure. Oregano oil is one of the best examples. This oil is naturally equipped to fight bacteria, and it is impossible for bacteria to resist.

While a number of studies have explored the viability of using Antibacterial Essential Oils instead of antibiotics, other researchers have proposed the notion of using essential oils and antibiotics together. Experts suggest that a combination of natural oils and antibiotic drugs may exceed the performance of individual oils, thus producing improved antimicrobial activity. They also advocate that the combined use does significantly reduce the minimum operative dose of antibiotics in fighting bacteria. As a result, the likelihood of adverse side effects from the use of antibiotics is reduced.

How to Use Essential Oils

Essential oils work on the body as well as the mind depending on the method of application used. These oils are volatile, and they easily evaporate into the air. Therefore, you can inhale or smell them, and they directly affect your brain. They enter the bloodstream through your skin, and take effect on your body. So, one of the best ways of getting natural oils into your body is through aromatherapy massage. The oils blend well with massage, including touching and applying substances to your skin.

The warmth of your body along with the hands of your therapist and the atmosphere in the room will make the oils evaporate. In turn, you will inhale the fragrance of the oil. Essential oils are normally safe when diluted with carrier oils, although applications are not recommended for epilepsy patients, and pregnant women. You are always advised to conduct a patch test before using an essential oil or an aromatherapy blend. In addition, you must confirm if an essential oil is phototoxic, because such oil can cause adverse side effects when you expose yourself to sunlight after a few hours of application.
