Alfalfa - a Potential to Future Folk Medicine

Alfalfa has been used for different purposes for centuries. Good feed for animals (Alfalfa hay for cows, horses, beef cattle, sheep, chickens, turkeys and others; can be by the way used as a pasture, hay, or silage crop), nice agriculture properties due to its nitrogen-fixing bacteria and a herbal remedy for many health problems – all that makes Alfalfa "father of all foods" (as Arabs called it when first discovered) and “a cure-all”.

Biological Description

Alfalfa’s scientific name is Medicago sativa, also known as Trefoil, Lucerne and Purple Medic. The name ‘Alfalfa is derived from the Arabic "al-fac-facah" that means "father of all foods"; the genus name ‘Medicago refers to Medea in North Africa from where this plant is considered to have originated; the species name sativa means "with a long history of cultivation". Its other names are: Spanish trefoil, Jatt, Chilian clover, Kaba Yonca, Brazilian clover, Buffalo Herb, French clover, Mielga, Medic and Mu Su. The plant belongs to the family of Fabaceae (a member of the pea family).

Alfalfa is a cool season perennial flowering plant. It is about 1 meter in high with a long deep root system that may stretch even to 4 m. Each flower of Alfalfa grows on its own stalk from a common stem with 10 to 50 individual flowers. They are purple to blue-violet; some have shades of white, creamy, yellow and bloom from July to September. Leaves are pinnately trifoliolate (three leaflets per leaf) and green, stipules are sharp pointed. The seeds of Alfalfa are yellow to greenish-yellow, browning with age.

The plant is cultivated as an important forage crop and is one of the most important legumes in agriculture.

Depending on the climate Alfalfa lives from three to twelve years. It can be sown in spring or fall.


It was first originated in Asia before 700 BC. (Some sources tell that it came to Greece around 490 B.C. being used as a horse feed for Persian army). Others tell that it has been cultivated first in Iran.

Besides western Asia Alfalfa is native to the eastern Mediterranean region and was originally found in Medea, Spain, Italy, France and Central Asia. Also in North America (the sources say that the plant was introduced to the US around 1860) . The US is the largest alfalfa producer in the world. The leading alfalfa growing states are California, South Dakota and Wisconsin. Now it is widely grown throughout the world.

Alfalfa has a wide range of adaptation. It is famous for its tolerance of drought, heat, and cold; for the remarkable productivity (it also has a tetraploid genome) and the quality of its herbage; and for its value in soil improvement. So, Medicago can grow in very cold northern plains as well as in high mountain valleys, and in rich temperate agricultural regions as well as in Mediterranean climates and searing hot deserts.

Alfalfa roots as well as other legumes have nodules that contain the bacteria Sinorhizobium meliloti with the ability to fix nitrogen. Rhizobium meliloti can only fix nitrogen within alfalfa (an interesting case of mutual partnership establishment).

 Alfalfa can be sown in spring or fall, and does best on well-drained soils with a neutral pH.

Parts Used

In folk medicine flowers, the leaves, the tops, the seeds and the sprouts are used.

Leaves and flowers are more used for the tonic purposes, for arthritis, gout and blood. Seeds more used as emmenagogue, hangover and stomachache; sprouts used in salad. Alfalfa extract is used by food makers as a source of chlorophyll and carotene.
