The whole corona virus thing in the news is quite worrying. I know that using an aromatherapy diffuser with certain essential oils can be very effective for respiratory illnesses and does a good job at killing germs in the air. Tea tree oil is pretty strong as an antiviral and antibacterial, however, tea tree oil is toxic to consume so don't swallow any of it.
Here's my aromatherapy diffuser recipe for colds and respiratory sicknesses:
4 drops of tea tree oil
4 drops of rosemary oil
4 drops of oregano oil
2 drops of clove oil
Water
If you put this in a diffuser and use for a few days it may help with colds and respiratory issues. Idk know if this would be effective in preventing or getting rid of the stuff in the news that's going around but it probably wouldn't hurt either. Tea tree oil can kill staph and mrsa and the other oils I listed have good antiviral and antibacterial properties. Wear disposable gloves if you are dropping essential oils into a diffuser and make sure you don't get any on your skin or eyes because it burns.
Stay healthy frens.
