Background

Wormseed (Chenopodium ambrosioides, Dysphania ambrosioides) is native to Central and South America and the Caribbean. Its name comes from the centuries-old use of the plant by the Mayan people of Central America to treat intestinal worms. Wormseed has also been used traditionally to treat asthma and dysentery and, in Europe and Northern Africa, to relieve menstrual cramps. Wormseed was used by the Aztecs to flavor food and is an important ingredient in Mexican cooking today.
The most common use of wormseed is the treatment of infection with parasites, such as worms. For this use, wormseed is taken by mouth. The active ingredient in wormseed is ascaridole. However, wormseed is toxic, and its use may result in poisoning and death.
Further high-quality human study is needed before conclusions may be made on the use of American wormseed for any condition.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older)
Wormseed is highly toxic and may be fatal when taken by mouth.
As a treatment to destroy intestinal worms, a concentrated extract has been made by boiling up to 300 milligrams of dry plant material per kilogram of body weight in water. The extract has then been taken by mouth. Doses of up to 6,000 milligrams per kilogram of powdered dried plant have been taken by mouth. A form of medicine, having the consistency of honey and made of conserves, powders, and bruised fruit, has been taken by mouth in doses of 20 grains (1,300 milligrams), according to anecdote. A liquid extract has been prepared, and 0.5 to 1 drachm (or dram, 1.78 to 3.55 milliliters) has been taken by mouth. Alternatively, an extract made by boiling one ounce of the fresh plant with one pint of milk or water has been taken by mouth in doses of a wineglassful.
