Interesting link! I took lots of licorice root/gotu kola when I was recovering from leaky gut/candida. Just seemed like the right thing to do, according to my Yoga of Herbs book. I was leary of taking it up again to deal with my last bout of extreme stress tho because licorice is an estrogenic herb. Hmmm... might take it up again just for a bit, see what happens. :)
