Plants having medicinal value grow in all of the earth's environments. The desert regions of the United States are no exception, and although the conditions are hot and dry most of the year, the medicinal plants in desert areas have adapted to these austere conditions. The indigenous people of the American Southwest used their plants wisely for food, clothing, building and medicine. They passed on their knowledge about the plants through oral history and mythology.
Also called butterfly weed, the Asclepias tuberosa is a member of the milkweed family. It likes to grow in prairies and canyons.

Licorice is well known for its use in candies and Chinese medicine. This one, Glycyrrhiza lepidota, grows in crowded conditions in fields and areas that have recently been plowed or otherwise disturbed.

The roots of licorice are made into cough drops, syrups and teas said to promote healing of the throat and lungs.
This medicinal plant, Ephedra viridis, was first used by early Mormon settlers in Utah to treat urinary infections, colds and other respiratory illnesses. It is related to the Chinese ephedra plant, which has been implicated for causing dangerous rises in blood pressure in some individuals. However, Mormon tea does not contain the high levels of ephedrine and is not considered hazardous to use. Use caution with any plant medicine, however.
