Hazards [3]  The plant contains saponin-like substances; Eating large quantities of the leaves may cause the breakdown of red blood cells; However, although they are potentially harmful, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. Thorough cooking, and perhaps changing the cooking water once, will normally remove most of them from the food. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish; Alfalfa sprouts (and especially the seeds) contain canavanine. Recent reports suggest that ingestion of this substance can cause the recurrence of systemic lupus erythematosus (an ulcerous disease of the skin) in patients where the disease had become dormant;

Usage [3]  Often grown as a green manure. It is a bit slow to establish in its first year so is generally only recommended for positions where it can remain for 2 or more years. Alfalfa is very vigorous from its second year, producing a huge bulk of material that can be cut down 2 or 3 times during the season; Plants are very deep rooting, descending 6 metres or more into the soil; Alfalfa is a potenially excellent source of biomass. It is possible to produce more than 2 tonnes of protein from the leaves (suitable for human use) per hectare per year. In addition, the plant residues remaining could be used to produce the equivalent of about 10 barrels of oil per year; A yellow dye is obtained from the seed; The fibre of the plant has been used in making paper; The seed yields about 8.5 - 11% of a drying oil. It is used in paints, varnish etc; The plant can be grown as a low dividing hedge in the vegetable garden;
