A watery extract of lathyrus peas and various salts isolated from them exert a marked action on the brain and spinal cord.
The salts are organic and inorganic phosphoric acid compounds, all of them having an essentially similar action, but differing in toxicity and in their local irritating effect.
Moderate doses cause torpor and depression, larger doses clonic-tonic spasms.
The action is probably a direct one and not indirect through causing a drop in the blood calcium.
