The Family Ambrosiaceae is also known as the Ragweed family, as they are the primary plant family that causes allergies. Common synonyms for this family include the Asteraceae or Compositae family, as the plants in this family often have composite flowers that are made up of many small flowers clustered together. Other synonyms for the Ambrosiaceae family may include the daisy family, the sunflower family, or the thistle family. These types of plants have a wide range of uses, such as for medicinal purposes, as food, or as ornamental plants in gardens. However, for those with allergies, they are often seen as a nuisance rather than a benefit.
