Type O's: tried Dadamo's Larch for constipation?

Hello Type O's everywhere - Dr. Dadamo recommends a substance made from the larch tree, in powder form, to take for type O's to help them deal with constipation. (He says Type O's shouldn't take psyllium, can't remember why on that part). THe larch he recommends is Larch Arabinogalactin. He says it is high fiber, and it also increases butyrate in the instestines (which is a good thing to have).

Has anyone tried the Larch? Did it help with constipation? Tweet
