Learn classical herb pairs as functional relationships

Dui Yao Interactive Tools is a focused study and practice resource for learning classical Chinese herb pairs by relationship, function, indication, and clinical logic.

Instead of memorizing pairings as isolated facts, the tools help you review how two herbs work together: what each contributes, why the combination matters, and how the pair can guide formula building thinking and a modular approach.

The slides below show the full-screen learning experience and the mobile review format. Use them to preview the structure, then try the demo to experience the interactive tools directly.

Happy practicing!
