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 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
