"True chamomile" is the most well-known and widely used wild chamomile. It grows naturally in North America and Australia, and is also found in abundance in central Europe, where it is very popular, hence its name "German chamomile". These days, it is grown in eastern Europe, the Balkans and South America. It is also called "matricaria chamomile", from the Latin "matrix" (womb, uterus), which refers to its use as an emmenagogue. It stands out from other types of chamomile with its hollow flower receptacle.
