What is it?

Alfalfa's roots can penetrate remarkably deeply into the subsoil and so gather rare nutrients. In herbal medicine, we use the dried leaves of Alfalfa, a plant grown all over the world for livestock but also having rich medicinal and nutritional benefits for humans as well.




How has it been used?

A. L. Blackwood, 1915 : Observations with Medicago Sativa (Alfalfa)

~ Clinical Cases.

Mr. D., aged 41, a chief clerk in the general offices of one of our railroad companies, had complained for several months of losing flesh. His appetite was poor, and he did not relish his food. An abnormal thirst was present, with a loss of flesh, and polyuria (frequent urination). Five drops of the Alfalfa tincture were prescribed, four times a day. After two weeks, he sent a messenger for a second supply of the medicine, stating that it had greatly benefited him. He called at the end of two months, having gained ten pounds. The urination had normalised, the appetite was fine, and he considered himself in a excellent condition.

Mr. G., aged 29, complained of a loss of weight and appetite, with excessive thirst, polyuria and mental depression. This syndrome had been developing gradually for the past year. Physical examination showed a man of medium size, emaciated, heart's action weakened, blood pressure lowered, stomach slightly dilated, prostatic portions of the urethra hypersensitive. Five drops of the tincture before each meal and on retiring gradually relieved the condition so that in three months he considered himself well.

Dr. Ben Bradley, of Hamlet, Ohio, believes that Alfalfa is one of our prime remedies. He reports a case where a woman had given birth to seven children, all born apparently strong and well, but when they reached the age of eighteen, each wasted away and died. When the last, a girl, exhibited the symptoms of the same wasting disease from which the others had died, Dr. Bradley made a concentrated tincture of Alfalfa seeds, fully saturated, of which he gave her ten drops, four or five times a day. Under this treatment her weight increased from 99 to 133 pounds, and she recovered good health.


Science on Alfalfa

~ One study with Alfalfa showed that it helped to neutralise carcinogens (cancer forming compounds) in the body -- another published in the Journal of the National Cancer Institute showed that it binds carcinogens in the bowel and helps speed their elimination from the body (Smith-Barbaro, P., Hanson, D., and Reddy, B. S. Carcinogen binding to various types of dietary fiber. J Natl.Cancer Inst. 1981;67(2):495-497)

~ Multiple animal studies have demonstrated cholesterol-lowering and triglyceride-lowering effects of alfalfa, without obvious effects on high-density lipoprotein e.g. (Malinow, M. R., Connor, W. E., McLaughlin, P., Stafford, C., Lin, D. S., Livingston, A. L., Kohler, G. O., and McNulty, W. P. Cholesterol and bile acid balance in Macaca fascicularis. Effects of alfalfa saponins. J Clin Invest 1981;67(1):156-162)) and (Cookson, F. B. and Fedoroff, S. Quantitative relationships between administered cholesterol and alfalfa required to prevent hypercholesterolaemia in rabbits. Br J Exp.Pathol. 1968;49(4):348-355) and (Yanaura, S. and Sakamoto, M. [Effect of alfalfa meal on experimental hyperlipidemia]. Nippon Yakurigaku Zasshi 1975;71(5):387-393)

~ Similar studies have shown that it may potentially have the ability to reverse athersclerotic plaques in the arteries (Malinow, M. R. Experimental models of atherosclerosis regression. Atherosclerosis 1983;48(2):105-118) and (Malinow, M. R., McLaughlin, P., Naito, H. K., Lewis, L. A., and McNulty, W. P. Effect of alfalfa meal on shrinkage (regression) of atherosclerotic plaques during cholesterol feeding, Atherosclerosis 1978;30(1):27-43)

~ An old case report documented hypoglycemia in a diabetic man taking alfalfa. After being unresponsive to conventional hypoglycemic agents, his blood glucose reached 648mg/100mL. Physicians allowed the patient to prepare an alfalfa extract he had used in the past. Two hours after the patient consumed the extract, he exhibited clinical signs of hypoglycemia with a blood sugar of 68mg/100mL. The extract was consumed 12 additional times when the patient had blood glucose levels ranging between 190-580mg per 100mL, each time resulting in a reduction of blood glucose concentrations. The reserachers at the time attributed this to the high levels of Manganese known to be present in Alfalfa. (Rubenstein AH, Levin NW, and Elliott GA. Manganese-induced hypoglycemia. Lancet 1962;1348-1351)

~ A substance extracted from alfalfa appeared to be beneficial in treating skin damage secondary to radiotherapy and healing gums after orthodontist operations. The substance contained cycloartenol, sitosterol, campestrol, and stigonosterol (Mac Lean JA. Unsaponifiable substance from alfalfa for pharmaceutical and cosmetic use. Pharmaceuticals 1974;81:339)

~ Alfalfa clearly possesses extremely high nutritional value and has been shown to be able to boost levels of both Vitamin D and Vitamin K. It is also very rich in chlorophyll and uncontrolled studies have shown that this compound can reduce bad breath.

Safety of Alfalfa

In general, Alfalfa extracts or sprouts can be used with confidence by all ages and by pregnant or breast-feeding women. The seeds of Alfalfa should not be eaten by anyone as they contain high levels of the toxic amino acid canavanine, something which is neutralised by the process of sprouting.

It may be wise not to consume a great deal of Alfalfa sprouts or medicine if using the contraceptive pill as Alfalfa contains isoflavonoids with estrogenic effects and large doses of alfalfa may interfere with the pill. Likewise, it may be a herb that will lower blood sugar levels if taken in sufficient doses, so a person using anti-diabetic medicine should carefully watch their levels, and need for medication, when using Alfalfa.

Alfalfa might interfere with immuno-suppressive drugs as it appears to have some immune enhancing properties. This is only theoretical however, as no cases of adverse interactions are reported in the literature,


Personal experiences

I use Alfalfa freely and frequently for people who are under-nourished, depleted and exhausted and I find that people consistently look healthier and better nourished after they use it for a while.

The tincture of Alfalfa is very interesting to use and it was reading accounts such as the above of its use in times gone by that really opened up my mind to its possibilities. How can we explain how a medicine used in doses that were measured in mere drops could have such a profound life-changing, life-saving effect?

There is more to life than the composite of its chemicals and people are more than machines. Looking around us, in any direction, we have to consider the possibility that there is a great deal of intelligence at work in the universe and it seems to me that this humble herb Alfalfa somehow brings a great deal of what is green, nourishing and good into a focal point that can do wonders when needed...

If I drink some Alfalfa tea then the first thing I can't help but think is that I've just taken a bunch of lawn-clippings and put them into a cup - it's not a bad smell at all, just rather like cut grass! Subsequently the taste is actually quite a pleasant surprise because it's really very agreeable and it's no problem at all to drink the whole cup.

The sense I have from drinking Alfalfa tea is one of a deep, warming, gentle nourishing action in my body. The effect is more warming than the temperature of the water warrants and it has an unexpectedly deep effect.

If I open up to it I can feel it reaching into my very marrow; the place I make my blood. I understand this kind of subjective tasting as a way to appreciate the herbs 'action' and I am sure this kind of experience is a large part of how we have come to know these plants as friends over the many generations we have used herbs as our first medicines.

I don't personally adhere to one or another regime of doses for just about any of our great herbs --people are too variable, their needs are too individualised, however I feel that adding even a little Alfalfa to a formula of teas or tinctures brings a remarkable amount of 'energy' into the equation and I am fond of using this herb when I see a certain kind of weakness or depletion shadow a person.

If you who are reading this are studying herbal medicine or have your own reasons to want to understand this plant ally at a much deeper level then I warmly encourage you to take a cup of Alfalfa leaf tea of a small dose of its tincture and then, with a quiet and attentive mind, observe for yourself how it makes you feel. This old method of 'experiential' learning may give you a greater appreciation of the herb's 'action' than any amount of academic learning about it.

Further to that, if you would like to learn more about the ancient art of pulse testing, a simple but powerful way to ask the intuitive intelligence of the body for its responses to a herb by feeling the pulse whilst giving a tiny dose by mouth, read here

Alfalfa combines exceptionally well with Nettles as a blood tonic and with Red Clover for a nutritive, cleansing medicine. For people who are anaemic or depleted it works perfectly with Panax Ginseng and Withania root.


Constitutional note

Much of the information here about the traditional uses of Alfalfa is consistent with the model of thinking whereby one may treat problem A with plant B. There is value in this approach, especially in how it helps us pass on useful knowledge to one another, but it falls short in one vital area; and that is that people are not all cut from the same cloth! Something that works brilliantly for one person may do less for another -- why is this?

The reason is that people vary in their constitutions as to whether they are either hotter or cooler and, at the same time, either dryer or damper. This interesting and useful subject is introduced further here

There is an old wisdom in treating the person first and the condition second and in this light Alfalfa shows itself as a herb that can particularly offer its benefits when a nourishing action is needed in the 'cycle of healing' - more about that here.

Dr Ben Bradley; excerpt on Alfalfa (from 1915)

I find in Alfalfa, after about seven years' clinical test in my practice and on myself, a superlative restorative tonic, but it does not act as a stimulant, after the manner of alcohol, cocaine or other habit-forming drugs. It rejuvenates the whole system by increasing the strength, vigour, and vitality of the patient.

In all cases, the ever-marked condition calling for the remedy is despondency, along with loss of flesh, whether the case is one of stomach trouble, such as indigestion, dyspepsia, general and nervous debility, anaemia, loss of appetite and poor assimilation, as shown by loss of flesh and constipation, with the always accompanying condition; depression. Alfalfa is especially useful with bottle-fed babies. It has done wonders in some cases accompanied by loss of flesh. It increases the flow of milk in nursing mothers, as well as the urine and the peristaltic action of the stomach and bowels, with a consequent increase of appetite and strength.
