Chest paralysis is a disease characterized by suffocation and pain in the chest and urethra. In ancient times, it was also called "heartache" or "heartache". The yang receives Qi in the chest and travels to the back. The Yang Qi in the chest is weak, body fluid cannot be transported and distributed, body fluid stops and phlegm accumulates, hindering Qi movement, so the chest is tight and painful, and even chest pain pierces through the back; phlegm blocks Qi, and the lungs fail to circulate and descend. Wheezing and coughing up saliva are seen; yang deficiency leads to phlegm condensation and qi stagnation, so the tongue coating is white and greasy, and the pulse is deep, stringy or tight. The pathogenesis of this syndrome is chest yang deficiency and phlegm blocking Qi stagnation. Treatment is to unblock yang and dissipate stagnation, promote qi and eliminate phlegm. Trichosanthes trichosanthes is a powerful medicine that regulates qi and widens the chest, clears phlegm and dissipates stagnation. This medicine is good at promoting qi and dispersing stagnation to widen the chest. It can also dilute and soften thick phlegm to clear the chest and diaphragm blockage. Xie Bai serves as a minister, clears yang and dissipates stagnation, promotes qi and relieves pain. Because this product is pungent, dispersing and bitter, warm and smooth, it is good at dispersing the stagnation of yin and cold, and relieving blockage of chest yang, so it is an important medicine for treating chest obstruction. The combination of Trichosanthes trichosanthes and Trichosanthes aeruginosa not only eliminates phlegm, but also unblocks Yang Qi, complementing each other, and is a commonly used medicine in the treatment of chest obstruction. Served with white wine, the pungent powder warms and promotes qi and blood circulation. It not only gently lifts the medicine upward, but also strengthens the power of Xiebai to promote qi and open yang.
