Substances the Calm the Spirit

1/11

Besides nourishing the Heart and calming the spirit, what is another important action of Ye Jiao Teng (polygoni multiflora caulis)?

Transforms phlegm; for cough with copious sputum
Tonifies blood and unblocks the channels; for soreness, pain, bi syndrome due to deficiency
Brightens the eyes and benefits hearing; for poor vision and hearing due to LV/KI deficiency
Anchor LU and ST qi; for coughing or vomiting due to rebellious qi

Ye Jiao Teng is a vine. Vines look like channels, so they often unblock the channels and relax the sinews.
