Hi, I generally squeeze a few drops of the lime juice in the palm of my hand and rub it under arm. I do this after I shower. After it dries you can apply deodorant if you like and you are guaranteed to stay fresh all day. Bedtime use is good too.
I find that I can use it every 3-4 days or longer and be secure. But you can use it more regularly if you please.
I want you to try it and report your results to me in a few days. I'd appreciate the feedback.
No, I've never used ginger in my bath water but I do like the brew. I beat a chunk of the ginger, pour hot water on it, let it seep for a bit and drink as is, or add a little sweetner.
