This is called 5 spice, but according to the package there are 6 ingredients: cinnamon, star anise, fennel, coriander, pepper, and liquorice powders.  
 
Interestingly, Chinese Five Spice is based on the five elements – fire, water, wood, earth and metal. According to traditional Chinese medicine, the five elements are manifested in different parts of the body and when there are imbalances in these elements, illness can result. For thousands of years,  herbs and spices have been used to restore balance in the body and that is why Chinese five spice powder came to be.
The ingredients and amount of spices vary greatly (thus some like this one have 6 spices) from region to region and even from household to household depending on personal tastes and preferences.
