Herb combinations

[Arzhela]

Reading through the "Powerful Bindrunes" discussion made me think about how the same principles would apply to herbs. There must be certain herbs, magickally, that work well together or various combinations that are more powerful than others. Does anybody have any info, ideas, or insight on this?

I think with herbs, the magical properties and medicinal properties are closely linked. You would not want to use two herbs that contradict each other medicinally. You would want to pick herbs that compliment each other.
