These plants, if fed with other herbage, do not seem to be injurious and apparently lose their harmful action upon being cultivated.[66] As long as salt is properly fed the animals will not eat this plant[67] and are said to suffer no effects from it. Physiological study has shown the presence of a body with marked sudorific power which causes rapid emaciation in frogs.[68] It has been claimed that these symptoms are due to the presence of a narcotic poison in the plant.[69] Post-mortem examinations were negative save for the presence of a peripheral neuritis.[70] * * * * * FOOTNOTES: [63] Maiden, J.
