Evidence of Benefit: |
Alfalfa is an immune-system stimulant that promotes normal blood clotting. It also aids in the assimilation of proteing, fats, and carbohydrates, and is an excellent blood purifier. Alfalfa alkalizes and detoxifies the body. It is a good choice as a mineral supplement. It has helped many arthritis sufferers and has been found to aid in the healing of a variety of illnesses, including intestinal ulcers, gastritis, liver disorders, hemorrhoids, bleeding gums, asthma, high blood pressure, eczema, anemia, constipation, body and breath odor, infections, burns, athlete's foot, and cancer. Alfalfa also acts as a diuretic and helps with urinary tract and bowel problems. Benefits of alfalfa for specific health conditions include the following:
Atherosclerosis: Scientific studies with animals have found that alfalfa leaf extracts lower cholesterol levels and help shrink atherosclerotic plaques. Alfalfa's effects on atheroslerosis is probably due to its effect on the activity of immune cells known as macrophages. Macrophages are drawn to sites of wear and tear in artery linings, where they form a platform on which cholesterol can collect. Alfalfa regulates macrophages in such a way that they are less likely to "lodge" in the linings of arteries and accumulate cholesterol. Alfalfa also slows the progress of atherosclerosis by keeping cholesterol from entering the body from food. The alfalfa saponins, which are soaplike compounds, form an insoluble foam with cholesterol inside the intestine. The resulting foam cannot be absorbed through the walls of the intestine and is excreted in the stool.
Cancer: Alfalfa has important uses in counteracting the effects of cancer chemotherapy. White blood cells, including granulocytes, leukocytes, and T cells, are the body's first line of defense against infection. Alfalfa extracts may increase the production of these white cells by as much as 60 percent. Studies in animals have found that alfalfa completely reverses immune depression caused by treatment with the cancer chemotherapy drug cyclophosphamide (Cytoxan, Neosar). Although alfalfa suppresses the action of macrophages (see above), it does not inhibit the activity of any of the immune cells the body needs during the first stages of infection.
Diabetes: The condition of people with diabetes who fail to respond to insulin greatly improves when they take alfalfa plus manganese.
Endometriosis: Doctors often prescribe synthetic estrogen, usually in the form of birth control pills, for the treatment of endometriosis. Naturopaths have favored herbs and foods with phytoestrogens, natural plant hormones that are related to estrogen but are less potent than the body's own estrogens. Alfalfa sprouts contain phytoestrogens that also block the body's estrogen receptor sites, thereby reducing the effect of a woman's own hormones.
Menopause-Related Problems: Hot flashes and other menopausal symptoms are rare among women who consume a lot of legumes, such as black beans, mung beans, and soybeans, which have mild estrogenic activity. Alfalfa has demonstrable estrogenic activity, too. In addition to acting like estrogen in women whose own sex hormone production has declined, phytoestrogens also appear to reduce the risk of estrogen-linked cancers such as breast cancer. Laboratory experiments show that phytoestrogens are effective in preventing tumors of the breast tissue.
Nosebleed: Alfalfa contains vitamin K, which helps blood clot normally. The level of vitamin K in alfalfa is not so high as to interfere with normal circulation.
Osteoporosis: Clinical studies in Japan have found that vitamin K, found in alfalfa and in green leafy vegetables such as kale and spinach, can partially prevent bone loss caused by estrogen deficiency. The vitamin interacts with vitamin D to increase the formation of new bone. The combination is not sufficient, however, to completely compensate for osteoporosis caused by estrogen-depleting medications.
Ulcers: Herbalists have long used alfalfa to treat ulcers, with good results. The bioflavonoids found in alfalfa build capillary strength and reduce inflammation of the stomach lining, while alfalfa's vitamin A helps to maintain the stomach's health. The herb's enzymes aid in food assimilation.

Consideration for Use: |
Alfalfa is not recommended as a primary treatment for any condition. Instead it should be taken in capsules or eaten as fresh raw sprouts that have been rinsed thoroughly to remove mold. Alfalfa seeds should never be eaten unless sprouted because they contain high levels of the toxic amino acid canavanine. Alfalfa is especially useful for replacing vitamin K that is depleted during treatment with a wide variety of drugs. Vitamin K deficiency is common among people being treated with antibiotics such as amoxicillin (Amoxil, Polymox, Trimox), cefaclor (Ceclor), gentamicin (Garamycin), streptomycin, and tetracycline as well as many others. It also may occur during treatment with cholesterol-lowering drugs cholestyramine (Locholest, Prevalite, Questran) and colestipol (Colestid), andy steriod drug taken internally, or the drugs ethotoin (Peganone), mephenytoin (Mesantoin), and phenytoin (Dilantin), which are used to treat seizure disorders. It is important to take alfalfa products certified as grown organically, since the plant concentrates cadmium, copper, lead, nickel, and zinc when it is grown in contaminated soils. Not everyone can benefit from alfalfa. Alfalfa should be avoided by pregnant women and by people with hay fever or premenstrual syndrome (PMS). In addition, the immune-stimulant effects of alfalfa may be harmful for those with autoimmune disorders. In fact, persons with clinically inactive lupus can activate the disease by taking large doses of alfalfa tablets. Alfalfa (and alfalfa sprouts) also should be avoided by people taking prescription warfarin (Coumadin) or other anticoagulants, since alfalfa counteracts these medications. |
Medicinal Uses: |
Internally for debility in convalescense or anemia, hemorrhage, menopausal complaints, premenstrual tension, fibroids, and other conditions indicating hormonal imbalance. Contraindicated in auto-immune diseases. Excess may cause photosensitization, and breakdown of red blood cells. To treat malfunctioning thyroid glad, diabetes, and elevated cholesterol levels. |
Typical Dosage: |
A typical dose of alfalfa is approximately 15mL-20mL liquid extract per day. |
Possible Side Effects: |
Alfalfa's side effects include photosensitivity and lowered levels of potassium in the blood. The seeds of the alfalfa plant contain a toxic amino-acid and should not be eaten. |
