Not exactly a Parkinsons problem but there have been other posts on how we can protect ourselves against the virus, so I'm posting this here for your interest. Thieves oil gets its name from the days of the Bubonic Plague when thieves entered the homes of the dead to rob them. They didn't catch the plague because they protected themselves with 'thieves oil', a mix of five essential oils. See the recipe on -healthline.com/health/thiev...
I made up a mix in a brown bottle, and I put six drops of the mix into water on an oil burner to purify the house and I have it on a hanky stuffed in a scarf to protect me if I'm going out into crowds. If I develop the virus I will add six drops of the mix to my bath. The article has more ideas.
I've just checked on Amazon and you can buy it ready mixed.
