Hyangseongpajeokhwan — The Principles of a Traditional Formula for Heavy Voice Users

The name itself reveals the formula's purpose

The name Hyangseongpajeokhwan (響聲破笛丸) translates as "clearing (響) the voice (聲) and breaking (破) the cracked (笛, flute-like) hoarseness". This traditional formula, recorded in the Donguibogam and Uihak-immun, is specially adapted to the vocal health of those who use their voice extensively.

Composition and roles of each herb

• Platycodon (gilgyeong, 桔梗): The chief herb that expels phlegm in the throat and opens the airway — called the "boat of medicine" because it carries other herbs upward.
• Perilla seed (soja, 蘇子): Descends lung qi and resolves phlegm.
• Donkey-hide gelatin (ago, 阿膠): Moistens the vocal cord mucosa and treats bleeding and dryness.
• Cnidium (cheongung, 川芎): Promotes blood circulation in the head and face, supplying nourishment to the vocal cords.
• Licorice (gamcho, 甘草): Soothes throat pain and harmonizes the other herbs.
• Mint (bakha, 薄荷): Cools heat and reduces swelling in the throat.

Indications

• Hoarseness from prolonged talking
• Voice that has not returned after a cold
• Phlegm stuck in the throat preventing a clear voice
• Vocal cord conditioning before performances or lectures

Modifications by constitution

The base formula remains the same, but the herbs are adjusted according to the patient's constitution.

• Heat-prone constitution: Add heat-clearing herbs such as honeysuckle (geumeunhwa) and forsythia (yeongyo).
• Yin-deficient constitution: Add yin-tonifying herbs such as Ophiopogon (maekmundong) and Scrophularia (hyeonsam).
• Qi-deficient constitution: Add qi-tonifying herbs such as ginseng (insam) and Astragalus (hwanggi).
