just so you know...2nd babies are, statistically, most women's fastest, easiest labor. With no 'help' at all.
I know a mom who had 2, 42-wk pregnancies, and 2 long labors. She decided to take one of these formulas to see if it would help her. Her 3rd pregnancy was only 41 wks, and the labor pretty quick. So she took it again for #4; her pregnancy was 43wks + 1day (tho labor was pretty quick).
You hear these stories about wonderful things happening for some women who take the formulas...but when you look deeper, you see that a) various factors *might have* contributed to the differences and b) there is simply no consistency in results, over large groups of women you see no evidence at all that the formulas work. For every woman I ever heard say the formulas are great, I've spoken to at least one other who says it either didn't do a thing or actually caused issues with prodromal labor and such.
Our bodies, when healthy, don't need 'medicine' to make them perform birth 'right'. A reasonably good diet, some regular exercise, good stable love at home, some kind of spiritual foundation, a generally positive outlook and no excessive stress in any area...these are the only things that maximize our potential for a normal birth. There are certainly women for whom herbal 'medicine' can be helpful in unusual situations. And anyone can benefit from herbal 'nutrition'--blessed thistle and various others are high in nutrients so they are basically 'concentrated food', not medicine per se.
I totally believe that herbs are wonderful, and should be the first things we reach for, nutritionally and medicinally. And I also believe that the people who created them are ppl who don't much believe that birth works! There really is no substitute for a reasonably healthy lifestyle and a positive attitude....not to mention the trust that one's womanly body was made to do the work of birth naturally.
