Double-Rooted Red Ginseng

I ran into Sabitrama again in front of the map, the same one I helped get herbs before. This time, he said he found a place where I can get an important herb that he needed for his new medicine. He asked me if I could go into that forest and grab Double-Rooted Red Ginseng for him. It was a reddish root split in two... I should remember it well and find the same one once I get to the top. The herb is in the forest owned by Shane of map, whom I visited last time...
