Chen Pi (Aged Tangerine Peel): The Classic Citrus Herb That Awakens Digestion and Restores Balance

Chen Pi (Aged Tangerine Peel) is more than just dried citrus—it’s a time-honored staple of Traditional Chinese Medicine valued for its ability to bring harmony back to digestion and breath. Carefully aged to deepen its aroma and potency, Chen Pi transforms sharp citrus into a warm, fragrant herb that gently supports the Spleen and Lung, helping move stagnant Qi, dry excess dampness, and restore balance after rich foods or long-standing digestive discomfort.

With its unmistakable orange-brown peel, bold citrus scent, and centuries of trusted use, Chen Pi bridges everyday kitchen wisdom with classical herbal tradition—proof that sometimes the simplest ingredients, when aged with care, become the most powerful.
