Codonopsis Lanceolata (M19-11)

Once I noticed the handrail of the front entrance had a decorative plant coiling itself from the ground side. I didn't know if it was a useful plant or a weed growing up to hang on. 

I searched it on the Google images. It showed me the name of it as Codonopsis lanceolata. Its health effect is great. 

It is used for the treatment of bronchitis, asthma, cold, tuberculosis, dyspepsia, and psychoneurosis. Wasn't it great when I a split second thought about is as the weed?
