Like the crystalized natural deodorants?

My mom says deodorant can cause cancer and alzheimers later in life. So she wants me to use all natural deodorants. I have bad BO and every deodordant I have does not work. Does anyone know any type of all natural deodorant that works well to get ride of BO(for teen girls)?

I know there are many, many natural deodorants to pick from. But the things is, that’s all I see… natural deodorants that are NOT also antiperspirants. So I was wondering if there are natural antiperspirant/deodorant combos out there that actually work (like, they REALLY keep you from sweating).
Thanks.
