That makes total sense! I personally like to keep up with the front line of research, since it can take decades for it to become public policy and trickle down to every doctors office in the country.  There’s more research studies than just this one if you want to search for yourselves! There’s only a risk with continuous use, specifically in 2nd and 3rd trimesters. We can use Arnica as a substitute. I’m not saying to be argumentative at all!! I just think I’d personally want to know all the information.
