When cramps become an issue Yarrow is a workable solution. It also increases urine flow which helps when you're in your 'fat' jeans and feel like they shrunk too. I don't need it often, but an grateful to have it around when I do.
Yarrow is also said to be good for infections and is supposed to bring fevers down by promoting sweating. There appears there may be some scientific studies to back this up, but I have neither read them nor do I have personal knowledge regarding these claims.
