Our family doctor (she practices Chinese Medicine) suggests footbaths, 15 minutes before bedtime, to increase kidney energy, and also in case of almost any other serious condition.
I hope your father finds his way out of this, with your help. Fields are a great way to address the condition on multiple levels (not just physical). Sending love (and also suggesting playing a couple of love fields, along with healing ones)
In TCM, the emotion associated with kidneys is fear. (weak willpower, insecurity, isolation)
You could try dry brushing. The removal of toxins is done by the kidney, liver, lungs and skin.
The skin usually is bloked. The removal of toxins by the skin is very limited, if you do dry brushing, it will began to use the skin for detox. The kidneys have less workload and use this to regenerate. There are people that with dry brushing heal the kidneys. In some cases it do wonders, in the worst case is something that help. The field most akin is Kanpu Masatsu, but I recomend doing it phisically.
It’s good news. The doctor came to see me today and said that my father looked very good, not like a patient in the intensive care unit at all.
