Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Alfalfa (Medicago sativa) is sometimes used in traditional and herbal medicine as a general "kidney tonic" or to promote urinary health. Traditional herbalists have recommended alfalfa for various ailments, including kidney stones, based on its purported ability to support kidney function and act as a mild diuretic. However, direct references specifically linking alfalfa to the treatment or prevention of kidney stones in traditional medical texts are sparse. Most mentions come from modern herbal compendia or anecdotal sources rather than well-documented historical usage.

From a scientific standpoint, there is little to no direct evidence that alfalfa has a significant effect on kidney stones. Alfalfa contains various vitamins, minerals, and phytonutrients, and it has mild diuretic properties that could theoretically increase urine flow and thus reduce the risk of stone formation. However, there are no clinical trials or significant in vivo studies demonstrating that alfalfa extract or supplements can prevent, dissolve, or treat kidney stones in humans. Some sources even caution against excessive use of alfalfa due to its high vitamin K content and potential for other adverse effects, especially in individuals with kidney issues.

In summary, while alfalfa has a place in traditional herbalism for general urinary or kidney health, its use specifically for kidney stones is not well-supported by either tradition or science, and evidence for its efficacy remains minimal (rated 1 out of 5).
