Medicinal uses:  The leaves are very astringent, it is an emetic and febrifuge.  It is put onto insect bites, and other skin complaints.  It is also a tea for the treatment of pneumonia, fevers, nausea, intestinal cramps, and diarrhea.  The juice of ground leaves is a disinfectant and it is applied to infected toes. Tea made from the roots is used for menstrual disorders and stroke.  The pollen is harvested commercially and used as a pharmaceutical for the treatment of allergies to the plant allergens.  The pollen from Ambrosia trifida is a major cause of hay-fever and other allergies.

Edible uses: The plant was cultivated by the Columbian Indians.  An oil is used from the seed. Seeds found in historic sites are 4-5 times bigger than today's.  It was eaten because the seed has up to 19% oil and it is better at drying than soybean oil.
