My husband and I have begun the task of refurbishing our home. Today I scrubbed, I mean REALLY SCRUBBED our 20-year-old shower. Seemed like a waste of time, because we will soon have it removed, but I just had to do it. What a disgusting job. By the time I was done I really did not want to go near that shower again. I was worried that I had aerosolized some bacteria and fungus. So I got out my handy diffuser and added 8 drops of Thieves essential oil (by Young Living) and let it run for 15 minutes. The whole bathroom felt refreshed and cleansed, and I had some peace of mind. There is some sound research about the antimicrobial effect of Thieves essential oil, but to tell the truth, I am happy if it was just the placebo effect. My mind tells me the bathroom is clean and safe, and that belief is supported by the Thieves aroma, so it must be true. It is nice to have something on hand to use for things like this.
