Alfalfa comes from the Arabic phrae “al-fac-facah,” which means “father of all foods,” and that is how I was first introduced to this plant. I will always think of alfalfa as one of the greatest nutritive tonics we have.

This time of year, as the sap begins to rise in the trees, so does our blood begin to quicken and move towards the surface. After a winter of being cooped up indoors, eating heavier foods without access to fresh fruits and vegetables, this is the time of year that our ancestors would begin to crave fresh, green, light and alkalinizing foods.  Alfalfa infusion offers an answer to this craving. It satisfies our bodies nutritional needs, while gently supporting detoxification so that our blood flows more easily to the surface.

Latin Name: Medicago sativa

Family: Fabiaceae (pea/legume family).

As a nutritive tonic, alfalfa has been used in a variety of chronic degenerative conditions, especially nutritional deficits are involved (i.e. anemia, osteoporosis).  It has a long history of being used by pregnant and nursing mothers to strengthen the blood, stimulate lactation and increase the quality of breast milk.

Alfalfa is one of the many legumes that contain phytoestrogenic isoflavones (plant compounds that mimic estrogen). Phytoestrogens can compete with estradial, a stronger estrogen, as well as xeno-estrogens (estrogen-like compounds found in plastics, pesticides, etc.) This produces a protective effect against estrogen-sensitive cancers such as breast cancer.  Phytoestrogens are also helpful during menopause, when women experience a decline in endogenous estrogen. Although plant estrogens are smaller and weaker, they do bind with estrogen receptors and can take the edge off of menopausal symptoms.

 It can have Its alkalinizing effect on the body helps to calm the nerves & muscles, remove acids from the digestive tract, reducing putrefaction in the gut, and cleansing the internal fluids and tissues. Alfalfa contains fructo-oligosaccharides (pre-biotics) which help to feed the beneficial bacteria in our gut and allow them to outcompete with the “bad” bacteria.

Alfalfa has also been shown to decrease cholesterol and cause regression of atherosclerosis.

It has traditionally been used to relieve water retention, arthritis and peptic ulcers.

Preparations:  Alfalfa seeds and sprouts can be used to top salads and soups. The aerial parts are dried for tea. It can be tinctured, but because minerals are not readily extracted in alcohol, it is best to tincture in vinegar or using a Spagyric method.
Alfalfa is an ingredient in our Strong Bones & Body Tonic and Pregnancy Tea

Dosage: Infusion: 1 heaping tablespoon per cup of water; Tincture: 30-60 drops in a little water 1-4 times per day (Assuming 1:1 potency).  Powdered herb:  5-10 g per day.

ContraindicationsPregnancy– There are mixed reports on this. Some say that plants with coumestans and isoflavones should be avoided during pregnancy and by women and men with fertility problems. These constituents have been shown to decrease fertility in animals who graze on these types of plants. It is thought that the constituent stachydrine has a stimulating effect on the uterus and should be avoided during pregnancy. This perspective, however, is based on a reductionist approach. 

No human studies or animal studies on Medicago in pregnancy or lactation have been conducted, but based on the nutritive, food-like nature of the plant, most herbalists consider Medicago to be safe during pregnancy.  In fact, alfalfa is an ingredient in the classic NORA tea that midwives recommend for pregnant mothers during the second and third trimesters. And, farmers often increase the amount of alfalfa in the feed of pregnant mares as it is more nutritious than grass hay and believed to benefit livestock. One study found that Medicago feed increased milk yield, lowered fat, and increased milk protein in dairy cows.14

Blood-Thinners: Because alfalfa contains vitamin K, there is a potential of an antagonistic interaction with blood thinning agents.

Lupus: Alfalfa is thought to exacerbate symptoms of lupus, possibly caused by immune system stimulation by L-canavanine. This constituent, however, is based on the ingestion of large amounts of seeds & sprouts. Alfalfa leaves, in tea or tincture form, contain trace amounts of canavanine and are considered to safe when consumed within the recommended dosage15.
