The oils in US and inter nations are EXACTLY THE SAME. The LABELS ARE DIFFERENT FOR EACH COUNTRY as the laws are different in every country. The oils are approved as SUPPLEMENTS in the US, meaning they can be ingested. They are not presented to HSA in Singapore or any other international country because it would take decades and millions/billions of dollars. Therefore, OUR bottles do not mention taking the oils internally. THAT is the ONLY difference. The essential oils are distilled and all the bottles filled from the SAME BATCH. Some then receive US labels, some Canadian labels, Some Australian labels, some Singapore labels, and so on for every country where Young Living has an office. (The Malaysian labels are different from ours).
It is totally up to YOU how you use the oils. I take them all internally if that is the most appropriate application.
