Realgar is known as ruby of arsenic. It is transparent, with dark red to orange-red color. It is used in production of fireworks, explosive and insect and snake repelent. This beautiful gem is known to be toxic. Realgar is used in the Chinese medicine. They mix it with rice liquor to make realgar wine, that is consumed during the Dragon Boat Festival. This drink is toxic and has become rarer practice.
