It is interesting to research superstitions.  This is especially true in light of the fact that many of our current daily routines harken back to superstitions of ancient times.

In modern day, outside of religious use, candles are now more likely to be used to set a mood or for their aromatheraphy value.

To follow is a guide to some of the most widely used aromatic additions to candles:

Mint - a strong claritive scent often used to refresh a room or as a wake up scent as it is uplifting and relieves mental stress.

Vanilla - one of the most widely recognized candle scents.  Vanilla is soothing and comforting.  It helps to calm emotions and ease tension and grief.  Vanilla is one of the 'sense memory' aromas.  It is also said to have aphrodisiac properties.

Lemongrass - has a lemony scent that also acts to repel insects but is not as abrasive as citronella.  This is a great evening bathing candle as  lemongrass reduces stress and acts as a sedative.  Try a candle with lemongrass for your evening winding down routine.  It also encourages self confidence.

Lavender - lavender is extremely versatile and it's soft floral scent is calming and balancing.  The scent of lavender also inspires sweet dreams and is used to soothe tension headaches.  Like vanilla, lavender is also a sense memory aroma.
