Special Precautions of Alfalfa
The alfalfa plant, especially the seeds, contains an amino acid called L-canavanine. Excess consumption of L-canavanine may cause abnormal blood cell counts, spleen enlargement, or the recurrence of active disease in patients with lupus. Exposing the seeds to extremely high temperatures may prevent this, but it hasn't been confirmed.
People with lupus or a family history of lupus should avoid alfalfa in any form.
Pregnant or nursing women, young children, or people with estrogen sensitive cancers should also avoid alfalfa because of its possible estrogenic effects.
Alfalfa has a high potassium content. People with chronic kidney insufficiency, hypoaldosteronism, or who are using potassium-altering medications should avoid alfalfa to avoid the risk of potentially life-threatening hyperkalemia (too much potassium in the blood).
Some health practitioners recommend that people who are immunocompromised should avoid the sprouts because of the risk of food poisoning.
Potential Drug Interactions
Alfalfa may reduce the effectiveness of "blood-thinning" drugs, such as warfarin (coumadin) because alfalfa contains vitamin K. Alfalfa should not be used with prednisone.

What is the Scientific Evidence for Alfalfa?
Although preliminary studies with human subjects suggest that alfalfa may lower total and LDL cholesterol, there haven't been any randomized, controlled trials to substantiate these initial findings.
In fact, there haven't been any randomized, controlled human trials on the use of alfalfa for any human health condition.
Alfalfa contains coumestans, which are phytoestrogens. For this reason, alfalfa has been examined in laboratory studies for menopausal symptoms.
