Abstract: Influenza virus causes high morbidity among the infected population annually and occasionally the spread of pandemics. Melaleuca alternifolia Concentrate (MAC) is an essential oil derived from a native Australian tea tree. Our aim was to investigate whether MAC has any in vitro inhibitory effect on influenza virus infection and what mechanism does the MAC use to fight the virus infection. In this study, the antiviral activity of MAC was examined by its inhibition of cytopathic effects. In silico prediction was performed to evaluate the interaction between MAC and the viral haemagglutinin. We found that when the influenza virus was incubated with 0.010% MAC for one hour, no cytopathic effect on MDCK cells was found after the virus infection and no immunofluorescence signal was detected in the host cells. Electron microscopy showed that the virus treated with MAC retained its structural integrity. By computational simulations, we found that terpinen-4-ol, which is the major bioactive component of MAC, could combine with the membrane fusion site of haemagglutinin. Thus, we proved that MAC could prevent influenza virus from entering the host cells by disturbing the normal viral membrane fusion procedure.

The effect of TTO on acidification of cellular lysosomes was studied by vital staining with acridine orange using bafilomycin A1 as positive control. The treatment of cells with 0.01% (v/v) of TTO at 37 °C for 4 h before staining inhibited the acridine orange accumulation in acid cytoplasmic vesicles, indicating that TTO could inhibit viral uncoating by an interference with acidification of intralysosomal compartment.
Additionally, the present study evaluated the antiviral activity of essential oil in aerosol form. Reasonably, the more effective TTO was used in such kind of evaluation. As was found in aerosol form, the TTO possessed the strong antiviral action as well as on the filter surface. The concentration of aerosolized virus in all experiments was kept at the maximum possible level, which was achieved by relatively high virus titer in the initial suspension prepared for aerosolization (∼107.5/mL). Use of heavily concentrated bioaerosol stream enabled acquisition of more than 103 virions by 1 mL of the collecting liquid (varied slightly in different experiments), which provides opportunities for evaluation of the process efficiency within three orders of magnitude, enabling to identify the inactivation efficiency at the level above 99.5%. These findings look very promising for the implementation of such aromatic substances in filtration applications to control the harmful bioaerosols, and further improvement of the indoor air quality. Such type of essential oils could be successfully utilized as effective disinfectant against of broad range of microorganisms as well in aerosol form as in form of filter coating substance.
Rosemary is known for having a very woody and even an evergreen like scent. It is actually part of the mint family and when you look at some of the more recent research that has been done, you will find that it can support the neurological tissue that is in the brain. Rosemary can improve your memory and it can also soothe any digestive issues that you might be experiencing. You will also find that rosemary oil can relieve any muscle aches and pains, with the remarkable ability to be a secret healer. In more recent years it has become a very popular ingredient in haircare products and it is also known for antiseptic properties as well. Read on to find out more.
Unfortunately, not all essential oils are the same. When you take a look at the amount of essential oils that are on the market, you’ll find that a lot of them are low quality and you will also find that they are made with other things as well. This makes it much easier for companies to produce a very inexpensive oil, while also selling it for a much higher price. Some adulterated oils can be very dangerous as well and for this reason, it is very important that you do everything you can to choose a reputable provider for your oils while also making sure that you are doing everything you can to use them properly.
