Isn't it interesting that until cattle overgrazed the west, Wormwood was not an abundant plant? When the west was covered with American prarie grass, Wormwood was only found in rare pockets here and there. Then came the cattle rush of the late 1800's. When cattle grazed away large tracts of grass - the eco-environment changed. God's perfect plan produced vast expanses of the Wormwood needed by people to get rid of the intestinal flukes produced by people eating the cattle that grazed off the grass. Something more than coincidence eh?
