Bests & Worsts Reviews from Amazon

I purchased Sun Essential Oils because the product claimed to be (1) pure; and (2) 4 fluid ouces for $14.99. This is a great price for real cinnamon bark oil. I did not care if the oil was 'Cinnamon Verum' oil (from Ceylon Cinnaman) or 'Cinnamon Cassia' oil (which is cheaper and is very commonly sold as real cinimon in the US; but cannot be sold as such in Europe). Pure, pharmaceutical grade, cinnamon bark oil, of either of the above varieties, will have an explosive, very hot cinnamon taste. I have tasted pharmaceutical grade cinnamon oil many times. This is NOT CINNAMON OIL. I had the Sun Essential Oils Cinnamon Bark tested by a relative, a biochemist. She said that the bottle contained 98% or 99% inert vegetable oil with a cheap cinnamon flavoring making up the balance. Anyone purchasing it for the health benefits of coumarin, which is always found in both Ceylon and Cassia cinnamon bark oil, should be advised that there is no coumarin in this product. THIS PRODUCT IS NOT REAL; IT COULD IN FACT BE POISONIOUS. I am sorry to have to use such strong language but the public should be warned. I have purchased many products from Amazon Prime and never before given a negative review.
