Lathyrus sativus - L.
Common Name Chickling Pea, White pea
Family Fabaceae or Leguminosae
USDA hardiness Coming soon
Known Hazards The seed contains a toxic amino-acid which, in large quantities, can cause a very serious disease of the nervous system known as 'lathyrism'. The seed is said to be perfectly safe and very nutritious in small quantities, but should not comprise more than 30% of the diet[65, 76].
Habitats Found as a weed of cultivated land though this is as a relict of cultivation, the plant is not known in a truly wild state[93].
Range The original habitat is obscure, possibly S. Europe.

 Cultivated Beds;
Edible Uses
Edible Parts: Leaves;  Seed;  Seedpod.
Edible Uses:

The immature seed can be eaten like green peas[2, 27, 183]. The mature seed is eaten cooked[2, 27, 46, 183]. It needs to be soaked and well cooked before being eaten[61]. The seed can also be ground into a powder and mixed with wheat in a ratio of one part vetch to 3 parts of wheat flour to make a protein-enhanced bread[2, 183]. Some caution is advised, see the notes above on toxicity. Young seedpods - cooked[105, 142, 183]. Young shoots - cooked[142, 183].
Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


The oil from the seeds is a powerful and dangerous cathartic[240].


Other Uses
Green manure;  Soil stabilization.

The plant has an extensive root system and fixes atmospheric nitrogen through bacteria that live on the roots. It makes a good soil-enriching green manure crop or can be planted for erosion control[200].
Cultivation details
An easily grown plant, succeeding in any moderately good garden soil but preferring a position in full sun[200]. The chickling pea is cultivated for its edible seed in India and the Middle East[61], but see notes above on toxicity. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.
Pre-soak the seed for 24 hours in warm water and then sow in early spring in a cold frame[200]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed, then it can also be sown in situ in mid spring[200]. Division in spring. It may not transplant well so care should be taken[200].

The common name of Lathyrus sativus in Ethiopia is guaya. In India it has many names, the main one is Khesari.
Fernand Lambein   Tue Feb 11 13:19:12 2003
Lathyrus sativus L. is most commonly called 'grass pea'. It has specific common names in most European languages: Graes-Fladbaelg in Danish, Zaailathyrus in Dutch, Forskolm in Norwegian, Ervilha quadrada in Portuguese, Almorta, guija or muela in Spanish, Plattvial in Swedish, Peltonatkelma in Finnish, Pois-carré, gesse cultivée or gesse commun in French, Saat-Platterbse or Platterbse in German, Laturi in Greek and Cicerchia in Italian. I guess this indicates ancient agronomic uses of the plant. In Ethiopia it is a survival food for the poor subsistence farmers. After a drought triggered famine, epidemics of the crippling neurolathyrism occur, the latest epidemic was in 1997-98. Ref.: Nettox list of food plants, Danish veterinary and food Administration,1998. Getahun H. et al.: Epidemic of neurolathyrism in Ethiopia, Lancet 354, 1999, 306-307

Detoxification of lathyrus sativus K. Jahan and K. Ahmad, Institute of Nutrition, Dhaka University, Dhaka, Bangladesh Ascorbic acid can sometimes revert the symptoms of Lathyrism. The neurotoxin in L. s. (ODAP) can easily be destroyed by soaking the seeds in lime water overnight prior to boiling.   Jun 1 2012 12:00AM
