The warmth and glow from the tea light candle bring about a wonderful reaction with the natural crystal salt. It clears the air and naturally dilutes odors so that we can breathe easier. People with asthma often find it helpful in reducing their symptoms and many medical practitioners recommend using these lamps to help relieve depression and fatigue. Ideal for your dinner table or place anywhere you want to be surrounded by clean air. Always place the candle holder on a coaster and never leave a candle burning unattended.
