A purified alkaloid preparation containing N-methylcytisine, cytisine, 5,6-dehydrolupanine, thermopsine and anagyrine from Thermopsis montana induced prolonged recumbency and microscopic acute hyaline skeletal myodegeneration with myofibre regeneration in cattle similar in type and severity to that
