Mugwort

I'm curious about a certain herb called mugwart. What i would like to know is what it is used for, where does it grow best, and what it looks and smells like.

Mugwort is a bitter herb used in cooking and medicine. Its flower buds improve the digestibility of rich meat, poultry or fish dishes. In Japan it is used for moxibustion which is a medical treatment where sprigs are burned in close proximity to vital energy channels in the body.
It promotes bile production which accounts for the effect on digestion. It has been added to baths to treat gout, rheumatism and tired legs.
It is easy to grow. It is a hardy perennial, growing up to 6 feet in height. It thrives in any well-drained soil. It does not have showy flowers (greenish-yellow, small) and is not considered useful for ornamental purposes, but it can be used effectively as a background plant in larger gardens. It is pleasantly aromatic.
