bubble_chart Formula Principles

This formula uses Ephedra to induce sweating and disperse cold, ventilating the lung and relieving panting. The root and nodes are not removed, ensuring that the sweating is moderated and not excessive. Bitter Apricot Seed is used to regulate lung qi, relieve cough, and resolve phlegm. The skin and tip are not removed, allowing for a balance between dispersion and astringency, preventing excessive diffusion. Liquorice Root is used unprocessed to clear heat and remove toxins, working in synergy with Ephedra and Bitter Apricot Seed to promote qi flow and dispel phlegm. The combination of these three herbs achieves the effects of dispersing wind, diffusing the lung, relieving cough, and calming panting.

The term "拗" (ào) means "contrary" or "against the norm." The preparation of the Three-Unconventional Decoction goes against conventional methods of processing materia medica. In the combination of Chinese medicinals, Ephedra is used without removing the root and nodes, Bitter Apricot Seed is used without removing the skin and tip, and Liquorice Root is used unprocessed. Hence, the name "Three-Unconventional" (三拗) is given.
