羊黄(别称:羊结石、羊宝)是一种中药。是由于消化不良、食物残渣凝结形成，具有较高的药用价值和收藏价值，

据资料显示，羊黄多产于病羊，年龄越大的羊有羊黄的可能性越大，羊黄为我国传统中药材，具有降逆风、开郁结、解毒、痰闭窍，痰火昏迷，热病澹妄，小儿惊痫之功能，是多种良药的重要原料。“羊黄确实比较稀有，坊间还有传闻说它可以治疗癌症。”据市中医院副院长雷正荣介绍，羊黄与其他药材搭配，可以起到化痰解毒的功能。在古代中医学上，有百病皆由“痰”起的说法，所以坊间认为，羊黄能够治疗癌症。其药用效果被东汉的《神农本草经》及李时珍的《本草纲目》《皇帝內经》等所收录，并且在国内外名贵药材市场上一路见涨现在羊黄在市场上都达到十几万一克了，成为各路投资者及收藏家的首要投资对象。

羊黄形成过程和珍珠类似，羊在采食过程中吃了一些不容易消化的、角质化的东西，慢慢形成一种异物，通过它自己的包裹，日积月累形成羊黄。放牧的羊才有可能产生羊宝，且个头很小，像个头这么大，全国都比较少见。最终经专家确认，刘先生取出的确实是难得一见的羊黄，药用价值极高。很多人一辈子都没见过。如猪宝一样，羊结石也称羊黄。“羊黄就是羊的结石，是由消化不良、食物残渣凝结形成，具有较高的药用价值和收藏价值。”
