good 为形容词,本句中意为"“(质量）好的”.
well一般当副词用,也是“好的”,但well还有形容词的用法,“专指身体好”,显然这里是指的药的质量故不用well.
这句话需要一个形容词做名词medicine的宾语,重点说的是用形容词来修饰says的评价,而不是用副词修饰"说"这个词本身.故选A

不是，楼主注意两个as之间的词是和主句有关的。这里，是 That medicine is good。good 做is 的表语。如：i work as hard as he.hard 修饰work。
he is as clever as we expect.. clever 修饰is。

这是一个主系表结构的形容词同级比较句型。good是形容词，故正确；而well是副词，若理解成形容词的话，词义错误。
