Thank you all for the information on Wintergreen. I didn't know about health hazards until researching it after my soap fiasco. I am a little concerned because it is going to an elderly family member as a gift. Also younger people that may also be on blood thinners. I used 3.1% (per SoapCalc's default .5 oz per lb). I really look forward to the challenge of using it, but may go half or third with another EO. It's just my most Christmas-y fragrance! And I have so much EO FO to use up. Thanks again!!!
