RELATION TO THE THEORY OF 12 MERIDIANS
Corresponding to the theory of 12 meridians in TCM, people have six
pairs of interior-exterior Yin and Yang related Zangfu viscera. Since
the nature of triple energizer had not been clearly understood, YECM and
YEEHC took triple energizer as one of Fu viscera that belongs to Yang
viscera. Its mutual Yin viscus was defined as the pericardium, which was
also regarded as a Zang viscus. TCM believes that the pericardium is
called the master of the heart and helps the heart perform its
functions.
After having a clear understanding of the triple energizer structure,
the nature of the pericardium is also clear, and it belongs to the part
of the new triple energizer connective tissue system (Fig. 2). The
pericardium is a specific connective tissue package of heart like
outsourcings of the other viscera, such as lung wrapped by both visceral
and parietal pleura etc. Structure of these packages are not a separate
viscus.
