Candles without paffin seems to be the key to not reacting to them with asthma symptoms. I just bought some candles/melts in a shop up steeple hill in lincoln. Took the bus up as my mum couldn't make the climb. When I get home I will burn them and see. Yankee candles are not good make me cough had to put them away from me. Shame as my children had bought them for me one more clue in retrospect that my asthma was getting worse and this was a good few years ago.
