Special feature from the Smithsonian's Sidedoor podcast: "King of the Herbs"

While Plant People is between seasons, we have a special episode, "King of the Herbs", from our friends at the Smithsonian's Sidedoor podcast:

It’s a wild herb that countless cultures have used for centuries as a wonder drug to cure any ailment. It's so rare and valuable that it’s been dug to extinction nearly everywhere, except a small area of the United States. This time on Sidedoor, we go searching for the elusive wild American ginseng—and find that scientists, conservationists, and criminals are also on the hunt.
