Thumbs up! [SEP] I was offered this tea tree oil through the Amazon Vine program and I purchased it for myself. To be honest, I don’t diffuse tea tree.. I’ve been using it for a toenail fungus that I’ve been battling for several years. I also put a few drops in my foot cream and my daughter uses a couple drops in her moisturizer that she applies to her face every morning and night. This oil is USDA certified organic with no additives or fillers. Also, it’s made in the USA. These are things that I look for while using it for medicinal purposes. The bottle is a brown, glass bottle, which is what oils are supposed to be packaged in.  The bottle is much smaller then my regular brand.... it’s only 1/3 fl oz. But, keep in mind.. less is more with this oil. If you’re going to use this on your skin, make sure you use with a carrier oil or an unscented lotion. I’m very happy with my purchase.
