May I ask why it is that you need this?
Since LU-1 is the alarm (Mu) point of the LU meridian, go to LU-5 (Chize) and gently massage it in a clockwise direction. This is the sedation point for this meridian. Also, since LU-1 is where the SP and LU meridians have a connection, you can go to SP-5 (Shang Qui) and do the same. This is the sedation point for the SP meridian. Use this as it will be effected by a strike to LU-1 as well.
There are more advanced methods of "treatment", but I'll not go over it on the internet. If you need more, go see a trained acupuncturist.
