Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Alfalfa (Medicago sativa) has been traditionally used as a nutritive tonic during pregnancy, particularly in Western herbal medicine. Historical records suggest that alfalfa was recommended for pregnant women due to its rich content of vitamins (such as vitamin K, C, and folate), minerals (like calcium and iron), and protein. Herbalists have often promoted alfalfa to help increase dietary intake of these nutrients, which are important for fetal development and maternal health. Additionally, alfalfa is sometimes used in late pregnancy to help prevent postpartum hemorrhage, thanks to its vitamin K content, which is essential for blood clotting.

However, while these traditional uses are well documented in herbal literature, there is a notable lack of robust scientific evidence to confirm the efficacy or safety of alfalfa supplementation during pregnancy. Most available information comes from anecdotal reports and small case series rather than controlled clinical trials. Safety concerns also exist, as alfalfa contains phytoestrogens and can, in rare cases, cause lupus-like symptoms or interact with medications. Therefore, while the use of alfalfa in pregnancy is rooted in tradition and its nutritional profile, healthcare providers generally recommend caution and advise consulting a qualified practitioner before using it in pregnancy.
