I spent quite a bit at these stores to save money. That was until I learned a few things: First, it cost me $20 to stop Lupus inflammation that could be deadly for me from being exposed to diffusers poisoning the air, in the stores, with volatile oils that can hurt and harm many people. Second, I called the owner or manager and spoke to lead workers, sharing this risky action, and they told me that it was pointless to share a lot of links corroborating regarding the health risks for many unsuspecting shoppers who could have terrible attacks, seizures, trigger neurological issues, and damaging inflammation hit them hard and fast. The basically said, "So what." Not my kind of people. I learned about it the costly way and they caused me degenerative damages and acted like it was no big deal. I have battled MS 39 years and Lupus almost that long. They really do not care. They got a little hostile in fact, and I was only sharing important information for protecting lots of people who would not know that it was exposure to the diffused oils at their stores that triggered something dangerous for them. https://www.livescience.com/25174-essential-oils-heart-health.html (This is only one of the hundreds of links with info on the health hazards from using 'essential oils'). I have to say that I learned back in the early eighties that these oils could do more harm than good; today more than ever. https://shannonsstory.wixsite.com/mysite (There is more about the oils and health risks in this website). read more
