Course Description

Cháihú 柴胡 Formula Family

A Clinical Masterclass for Pattern-Based Practice

In this 4-hour intensive, you’ll develop real clinical confidence using the Cháihú 柴胡 formula family—core prescriptions for resolving shàoyáng patterns and complex interior-exterior presentations in classical medicine.

Rather than treating Cháihú formulas as simple “harmonizing” prescriptions, you’ll learn how to recognize the deeper constitutional and pathological patterns they address and apply them precisely in modern clinical settings.


What you will learn

By the end of this class, you will be able to:

• Identify constitutional types that respond best to Cháihú-based formulas
• Recognize hallmark tongue, pulse, and abdominal findings
• Differentiate similar clinical presentations with precision
• Understand when to modify formulas and how to do so safely
• Avoid common prescribing errors
• Apply these formulas confidently across a wide range of conditions
