The four homoeopathic drugs, Gelsemium, Cannabis Indica, Graphites and Agaricus Muscarius, administered orally in 30th and 200th potencies on white rats, enhanced restraint-induced catalepsy in a similar manner to the two standard drugs pilocarpine and haloperidol (IP injection at 5 mg/kg). All the drugs tested differed from each other in the duration of cataleptogenic effect, which was more prolonged with Cannabis, Graphites and Agaricus than with Gelsemium and the two non-homoeopathic drugs used. The 200th potency of any homoeopathic drug tested acted longer than its 30th potency.
四种顺势疗法药物，即钩吻、印度大麻、石墨和毒蝇伞，以30C和200C药力口服给予白鼠，其增强束缚诱导的僵住症的方式与两种标准药物毛果芸香碱和氟哌啶醇（腹腔注射，剂量为5毫克/千克）相似。所有受试药物在致僵住症效应的持续时间上彼此不同，大麻、石墨和毒蝇伞的效应持续时间比钩吻以及所使用的两种非顺势疗法药物更长。所测试的任何一种顺势疗法药物的200C药力比其30C药力作用时间更长。
