Effects of smoking damiana?

I am going to buy the 2 OZ Damiana leaf package on Amazon and I am wondering if it will give you a "relaxing" feeling when smoked. I know that Black Mamba and herbs with chemicals in them give you a "high" feeling, but I want to know if the leaf itself can you at least a mellow feeling. I plan on mixing it with other herbs like Passion Flower, Mugwort, Mullein, and Skullcap.
