in botany, common name for members of the Fabaceae (Leguminosae), a large plant family, called also the pea, or legume, family. Numbering about 650 genera and 17,000 species, the family is third largest, after the asters and the orchids.

 family), the most important pasture and hay plant in North America, also grown extensively in Argentina, S Europe, and Asia. Probably native to Persia, it was introduced to the United States by Spanish colonists. Of high yield, high protein content, and such prolific growth that it acts as an effective weed control, alfalfa is also valued in crop rotation and for soil improvement because of the nitrogen-fixing bacteria in its nodules. The several varieties of the species grow well in most temperate regions except those with acid soil or poor drainage. The alfalfa belt of the United States centers chiefly in the northern and western parts of the country. Young alfalfa shoots have been used as food for humans and have antiscorbutic properties. Carotene and chlorophyll for commercial use are extracted from the leaves. Alfalfa is also called medic, the name for any plant of the genus Medicago—Old World herbs with blue or yellow flowers similar to those of the related clovers. Black medic (M. lupulina) and the bur clovers (M. arabica and M. hispida) are among the annual species naturalized as weeds in North America and sometimes also grown for hay and pasture. Alfalfa is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

Wow. Where do I start. Alfalfa is a purplish-flowered clover with roots that go very deep -over 100 feetreaches nutrients that other plants can't reach. It's called the land version of sea kelp because of high mineral content for strong bones, hormones and immune system. It alkalizes blood. It's a complete B complex, C, D, E, K, octacosanol, calcium, chromium, iron, manganese, magnesium, selenium, silicon, sodium, sulfur, trace minerals, zinc, coumarins, 8 digestive enzymes, all 18 essential amino acids (making it a major source of protein), fatty acids, and saponins. Alfalfa is the richest source of phytoestrogens. It stimulates and nourishes the pituitary gland, protects from radiation poisoning, neutralizes acids & poisons in the body, treats arthritis, cancer, ulcers, strengthens all tissues, bones, rebuilds teeth, stimulates digestion and bowel action, rheumatoid arthritis, balances blood sugar, diabetes, preventing absorption of cholesterol, energy, indigestion, dyspepsia, anemia, loss of appetite, poor assimilation and cleanses the colon. Whew. Dry it, grind into powder, make tea, juice or put into smoothies. Helps weight gain, stops bleeding. Anti-fungal. High source of chlorophyll. Rejuvenates the whole system. Don’t eat too much at once or take if you have lupus.
