I hope this is the correct SE site for this question. I think most people like me are interested in avoiding putting chemicals under our arms that can put our health at risk. I found this recipe for DIY natural deodorant. The author of the article claims it works very well even after her cross fit workout.
Like you all, cost is also an important consideration for me. Shea butter is imported from Ghana Africa. After some searching I saw that avocado butter can be used in its place but that was for making soap.
Ideally the most cost-effective recipe would have all its ingredients sourcable from my back yard garden so a trip to the store would not be needed. I live in New Jersey USA.
