15 Medicinal Health Benefits Of Alfalfa (Medicago sativa)

Alfalfa, scientifically known as Medicago sativa, is a perennial flowering plant that belongs to the pea family. It’s primarily cultivated as a forage crop for livestock due to its high nutritional value.

Alfalfa has deep roots, enabling it to access nutrients from deeper in the soil, and it’s known for its ability to fix nitrogen, enriching the soil where it grows.

It’s rich in proteins, vitamins (such as A, B, C, E, and K), and minerals (including calcium, magnesium, and potassium). Alfalfa is commonly used in animal feed, often in the form of hay or pellets, and it’s also consumed by humans as a nutritious addition to salads and sandwiches.

Additionally, its roots have been traditionally used in herbal medicine for various health benefits due to their potential medicinal properties.
