This was taken from Elaine's Aromatheraphy. Please go here for the full list. Also check out this list of essential oils which are known to be skin sensitizers.
Cyanide is a highly toxic poison and the word "carcinogenic" is used to describe a substance that is capable of causing cancer.
Please be extremely careful when handling essential oils. It is mentioned in the article that a 15ml bottle of Birch and Wintergreen essential oil has enough methyl salicylate to kill a person if ingested. They are particularly dangerous to children because of their sweet and minty smell.
In fact, any essential oil should be kept out of reach of children and thoroughly researched before being used. It is better to err on the side of being TOO careful.
Maybe not the best topic to start the new year with uhh hehe.
