Is Alfalfa safe to use?
Contains vitamin K, which can interact with blood-thinning medications like warfarin — maintain consistent intake rather than varying it if you take one. Not recommended in autoimmune conditions such as lupus, since alfalfa seed and sprouts contain an amino acid (L-canavanine) linked to autoimmune symptom flares in some case reports — this concern is specifically about seeds/sprouts rather than the dried leaf, but caution is reasonable either way. Avoid during pregnancy in medicinal (non-culinary) amounts.
