Yes, totally. Don't go for tea brands; they almost only make blends, and that's sub-optimal. Go to a natural food store or specialised tea store and buy a bag of pure dried spearmint. Put into a metal tea ball, add water, and poof, spearmint tea! Ordering from the Internet can also be worth it. I bought mine from Davidstea, and the shipping was free if I ordered two large bags. Though that's a Canadian chain, so shipping might not be possible if you're elsewhere. But really, just look at the website of a specialised tea store chain that you know, or a general online shopping website. You should find some pretty easily.
Oh, and just so you know, peppermint does not have any anti-androgenic effect. Make sure you check. Sometimes it's just written "mint". If you have no way of knowing, assume it's peppermint, since with its more intense taste, it's what's the most used.
