Alfalfa
Medicago sativa
Family: Fabaceae

Introduction

Alfalfa is a perennial legume that grows up to 3 feet in height and produces blue-violet flowers from July to September.1 It was cultivated from a species which originated in southwestern Iran, the Caucasus, and eastern Anatolia.2 Alfalfa was domesticated for feeding animals in the Near East during the Bronze Age between 1000 and 2000 BCE and was being grown in Europe by 400 BCE.2 It is now cultivated throughout the world.3

History and Cultural Significance

Due in part to its high protein content, alfalfa is regarded by many as the best crop for feeding livestock.4 It was used in horse feed by Arabs who claimed that the plant made the horses swift and strong.1 Arabs gave the legume the name alfalfa which means “father of all foods”. They used alfalfa medicinally in the belief that the leaves possessed a diuretic effect that was useful in the treatment of kidney, bladder, and prostate disorders. Historically preparations of alfalfa leaves have been used to treat arthritis, diabetes, upset stomach, and asthma. The leaves are used as a nutritional supplement as they are high in protein, vitamins, and minerals.1 In India, the seeds of alfalfa have been used historically in a cooling poultice for boils.4 The mucilaginous (moist and slimy) fruits are utilized for coughs in Colombia. The seeds contain alkaloids that are believed to stimulate menstrual flow and lactation.4

Modern Research

One study suggests that alfalfa seeds in the diet may help support cardiovascular health in certain populations.5

Future Outlook

Information concerning the market statistics and sustainability of alfalfa pertains to its use as a livestock food crop. Aside from being considered an invasive weed in some areas and sometimes becoming contaminated with bacteria such as Salmonella and E. coli, there are no issues affecting the future of alfalfa.
