We've used Doterra for years, for about 10 years. We use the crap outa them. Oregano has helped us avoid antibiotics, we use orange, lime, peppermint, lavender, frankincense, tea tree and other. I could tell you all kinds of stories. They have been a huge benefit to us. PS: We are in early 60's, my wife has had zero antibiotics since she started and I have been on twice, both for ear / sinus, in 10 years. Oregano and shit tons of C from differing sources.
