The market to see the mullein is in fact the drop sunflower, and not is the drop sunflower, just drop sunflower one, because some of the drop sunflower can not be eaten directly, can only be sliced and preserved as a medicinal use.

The market of most of these dropwort folk collectively known as tofu vegetable or wood ear vegetable. Some of the information on the dropsy is also known as watercress, because the fungus is an ancient vegetable, a long time ago, because of the ancient communication is not developed, the region is different, so the local people have their own way of naming a lot of food. And the country's large population, regional differences, it is easy to repeat the name of certain foods.

I've never been to the north, and I don't know if local people will confuse mullein with watercress, but I can tell you for sure that in the south (I live in Guangzhou), watercress is watercress, mullein is mullein (or tofu), and no one calls mullein watercress watercress.
