Hi Claire
This is an interesting topic. Often students who have had a gall bladder removed have a similar question. First, let's remember that the acupuncture meridians are bilaterally symmetric, which means you have two—one on each side (you have a "back-up"
). Second, the Organs in the Daoist philosophy can be considered
organ functions, not just the physical tissues that make up the organ. Every cell in the body needs to manage water (kidneys/bladder), metabolize nutrients (liver), obtain oxygen (lungs), etc. Thus the meridians bring chi to all cells. The lack of a gall bladder does not destroy the Gall Bladder meridian. Similarly, the loss of the lower part of the 6 meridians that end or begin in the leg will not prevent chi from flowing through the remainder of those meridians.
I know that acupuncture has been used successfully to treat phantom limb pain: the technique is to stimulate the points on the remaining limb. Thus, TCM practices can still be effective even if some parts of the body are missing. However, there obviously will be some changes! The 12 main meridians are given 12 different names depending upon where it is, but in reality they are all part of one grand, long loop. Like a street that is given different names despite being one continuous stretch of road, there is just one meridian (with many branches and sub-channels like a river delta) that interconnects everything in the body. If the lower part of the leg is removed, does this disconnect some of the branches? I don't know the answer to that question, but I suspect it will have some effect. Perhaps when this occurs, it is even more important to do our practice to make up for the loss or reduction of chi flow. Students without a gall bladder are advised to do more work that stimulate the GB meridian. The same may be advisable for amputees.
At the end of the day, what is most important and relevant to your student is not what I or any other teacher thinks or says, but — how do they feel? If the practice feels helpful, then keep going! If it feels detrimental, try some alternatives, experiment and if still no benefits arise, do something else.
I hope this helps a bit.
Cheers
