Best natural deodorant????

Hello all! I'm at a bit of a crossroads with managing my natural odor. I was born and raised in what would be easiest decribed as a hippie home. I've learned so much about the link between breast cancer and aluminum and commercial deodorants and I only use it if I absolutely have to. I've been using a coconut oil/cornstarch/baking soda combination for a long time now, and it works fantastically, but I can no longer use it. The baking soda in it irritates my skin and turns it a very noticeable red, and the coconut oil sometimes plugs my sweat ducts and my lymph nodes that are in my underarms, which is very painful and makes bras almost impossible to wear. And "natural" deodorants that you can buy (like Tom's, Mill Creek etc.) are mostly just an antibacterial essential oil (like tea tree or need) and some vegetable glycerin, which only hold the smell back for about half an hour, meaning I have to re apply about 10 times a day. Do any of you have other natural deodorants that work for you? please help!
