Homemade Deoderant/Antiperspirant

Sounds pretty loony, huh? But, I thought I'd give it a shot. I researched several recipes. The one I wanted to try was on the angry chicken blog; the one I ended up using was one one green generation's recipe. Except that I tweaked it. You can read on one green generation about her experience. Here's what I did:
1 part non-aluminum baking soda (I did 2 Tablespoons) to 4 parts corn starch (I did 8 tablespoons), add several drops of essential oil or, in my case, Trader Joe's lavender body oil.

Mix in a food processor. Put in a small jar (mine is a washed out lemon curd jar). Apply with a make-up pad, cotton ball, or knit/crochet a small cotton pad like the one I made.

I needed a bit more baking sodathan one green nation 'cause I guess I just have a stonger or more prolific smell. What I like about this is you can adjust the ratio of baking soda/cornstarch based on your body type. No rashes yet and I've been using this for a month. Hope it keeps working, 'cause it's way less expensive and works even on those very hot days.
