【黄环】
味辛、苦，性寒、微寒，无毒。主治寒热往来，中风，抽搐，痉挛，惊悸癫痫，邪气侵袭，消除症瘕积聚，瘀血停留于肠胃之间，安定五脏，治疗痈疮。去除时行疫病引起的头痛、客热（外感发热）、五劳（五种虚损）、劳气（因劳累产生的病气），以及头腰痛、风毒导致的牙关紧闭、癫疾。又名鹿韭，又名鼠姑。产于巴郡山谷及汉中地区，二月、八月采集根部，阴干。（害怕菟丝子、贝母、大戟；现今东方也有出产，颜色赤红的为好，使用时需去心。按：鼠妇也名为鼠姑，而此处名称相同，大概不是同一类植物，恐怕是文字错误。）
【另一种黄环】
味辛、苦，性平、温，无毒。主治风寒，温疟，热气，各种痫证，祛除邪气，通利大小便。治疗水肿，风肿，清除膀胱热邪，伤寒，寒热邪气，中风导致的手脚挛急，止泻，消散痈肿，恶结，各种疥癣，虫疮，疏通腠理，通利九窍。又名解离，纹理像车辐条一样放射状分布的质地优良。产于汉中川谷地区。二月、八月采集根部，阴干。（殷孽作为引经药，能解除雄黄的毒性，与细辛相恶，害怕萆薢。）
现今产自宜都、建平，个头大而呈青白色，质地虚软的为好，颜色黯黑且坚硬的不好，服用养生也需要它，是治疗风水病的要药。
【第三种黄环】
味苦，性寒，有毒。主治痂疡、恶败疮，去除三虫、邪气。产于益州川谷地区，二月、八月采集。（《新修本草》卷三六五页，《大观本草》卷三十，《政和本草》五四六页）
【第四种黄环】
味苦，性平，有毒。主治蛊毒，鬼疰（一种传染性极强的疾病），鬼魅（指精神异常或迷信中的邪祟），邪气在脏腑中，消除咳嗽逆气、寒热。又名凌泉，又名大就，产于蜀郡山谷。三月采集根部，阴干。（鸢尾作为引经药，与茯苓、防己相恶。）
形状类似防己。也呈现车辐条状的纹理。《蜀都赋》中所说的“青珠黄环”，有人说那是大戟的花，肯定不是。世间的用法很……
