Alfalfa tea (medicago sativa) is generally taken as a nutritive tea. It provides small amounts of vitamins (including a precursor to Vitamin A, vitamin E, B1, B2, C, D, and K) and minerals. It also offers phytoalexins, alkaloids, saponins, and chlorophyll. Because alfalfa roots grow deeply in the soil, the plant has access to minerals not commonly found in many herbs.

Chlorophyll is one of the main reasons alfalfa is used. You should be aware that it also increases appetite in most individuals, which can be a benefit to some, but should of course be avoided or used with caution by anyone trying to lose weight.
