Hi Frederic,
If you are doing a full Lou treatment, you simply bleed the Lou vessels but paying attention to when the color changes from dark to light, at which point you stop the bleeding so as not to make the patient weak if not enough resources. In the empty Lou treatments, you would harmonize blood by needling one point distal to the He-Sea points.
So strictly, you don’t need to be concerned about the weakness of the patient when doing Lou’s. Also, pay attention to when you notice a shift with the patient on the table such as deep inhalation and exhalation after you bleed a certain Lou point. Once you notice a shift like that, you no longer need to perform any further bleeding and can move on to the next phase of your session or leave it as is. Keep it focused.
I’m not sure what you mean by 6 flowers or tonifying bladder but generally it is okay to do any other treatment after a Lou session.
