my chinese tai chi teacher told me that a pressure point that she calls "yung chuan" on the sole of the foot serves well in stimulating the heart. therefore, in many forms of tai chi, the foot is briefly set up on the front part, resulting in a stimulation of that point.
from her description i conclude that she is probably talking about kidney no. 1. however, i do not find any heart-related indication for this point. can anyone smarten me up?
