"I never travel without this"
(Citizen of the World)
I have purchased this product now 3 times during the last 3-4 years. There is no infection that can keep up when you put a couple of drops of Oregano oil in water and drink these. Not a pleasurable experience, but you can say bye, bye to antibiotic use with these. It has saved me at least 2 trips in the past from infections I had during the trips. Otherwise, it could have put a stop on the whole journey.
I have used another brand in the past, which was good also but I like the purity of this one.
