good question. Im not sure myself, but then again i haven't tried much if you really think about it, there are probably endless ways to try and heal an ailment.. Lets say you try to use apple cider vinegar on your armpits but the odor comes back. Same with baking soda. So you cross out the two out of your list. But in reality, if you used the two together, all of a sudden a miracle happens and your underarm BO is gone for the whole day and night. There are soooooo many different ways to combine things that maybe someday someone will find their combination that will cure them. As i have always told myself- there's never one cure for people. Usually its a combo of things. Change of lifestyle, habits, sleep, or products that truly heal the person back to baseline. I hope that made sense!
