This Teishin is usually used with spreading needle technique, but in this case it was used in a different way. The patient came with another main complaint, but at the end of the treatment she told me she had sinus congestion on her left side and that was disturbing her sleep condition. So I picked up Teishin for Ja Removal and placed it at some points on her left cheek and nose area. After such treatment, she said her sinus and nose was opened.
Teishin for Ja Removal seems like it can be used like a "chimney" if it is placed where Ki (energy) is stagnated.
