Star of David incense

I took this photo in Mexico City, in a huge indoor/outdoor market called Mercado de la Merced (Merced for short). It was in the section dedicated to healing, herbs, natural remedies, brujas and curanderos. I was tickled to discover a Star-of-David-themed incense. (What do you suppose it smells like?)

I have another question: What is the six pointed star doing on this product?
Anyhow - I like the colors...
