In the Middle Ages, Topaz was thought to strengthen the mind, increase 
wisdom, and prevent mental disorders.  Powdered topaz added to wine was 
used to prevent asthma and insomnia.   A cure for weak vision involved 
immersing the stone in wine for three days and nights, then rubbing the 
liquid on the eyes.
Topaz allegedly attracts joy, generosity, abundance and good health, as well as releasing tension and aiding the digestion.
