Wilted Tribulus terrestris plants were harvested from a camp in which geeldikkop had just previously broken out. The plants were treated in various ways in an attempt to preserve their toxicity. The only successful method of preservation found was rapid freezing of harvested material. Three kg of plants were kept frozen for six weeks and then dosed via rumen fistula to a sheep which subsequently developed characteristic symptoms and lesions of geeldikkop.
萎蔫的刺蒺藜植株采自一个此前刚爆发黄疸病的营地。对这些植株进行了各种处理，试图保留其毒性。唯一成功的保存方法是将收获的材料快速冷冻。三千克植株被冷冻保存六周，然后通过瘤胃瘘管给一只绵羊投喂，这只绵羊随后出现了黄疸病的典型症状和病变。
