Wow! I remember alum... it used to be the "thang" for some women [in my community] after childbirth...not directly after childbirth but was known to tighten up the loose "ends" for sexual purposes. One time, a friend of my mom's put some on her breasts because of its fullest of milk [and the pain associated with it]...big mistake! It not only caused her breasts to draw up, it also made the condition permanent. Life lessons huh? Alum is an old remedy folks back in the day used to use....however, lately I haven't heard mention of women using it anymore to tighten up those "vagina muscles"...well.... until now!
