Efficacy and Functions of Xinhui Chenpi

Core Therapeutic Effects

Promotes digestion; lowers blood pressure and prevents aging; resolves phlegm and relieves cough; regulates Qi and strengthens the Spleen.

Introduction

Xinhui Chenpi (aged tangerine peel) is a specialty product of Xinhui District, Jiangmen City, Guangdong Province. Tangerine peel improves with age—the longer it is stored, the better its quality. Peel stored for less than three years is referred to as “fresh tangerine peel” or simply “tangerine peel,” whereas only peel aged for three years or more qualifies as authentic “Chenpi” (aged tangerine peel). Xinhui Chenpi is renowned for its distinctive, rich, and aromatic fragrance—a hallmark of its superior quality. Due to its high medicinal value and longstanding use as both a traditional spice and flavor enhancer, Xinhui Chenpi enjoys an esteemed reputation.

Therapeutic Effects and Applications of Xinhui Chenpi

1. Promotes Digestion

This is the primary therapeutic effect of Xinhui Chenpi. It stimulates appetite and aids digestion by promoting gastric juice secretion and accelerating the breakdown and metabolism of dietary fats and proteins—thereby facilitating efficient digestion and nutrient absorption. It effectively alleviates symptoms such as indigestion, poor appetite, and abdominal distension or pain.

2. Lowers Blood Pressure and Prevents Aging

Xinhui Chenpi helps lower blood pressure and combat aging. Its volatile oil component, hesperidin methyl chalcone (a derivative of hesperidin), promotes vasodilation and increases coronary blood flow, thereby reducing blood pressure. Moreover, extracts from Chenpi enhance both humoral and cellular immunity while suppressing oxidative damage caused by oxygen free radicals and lipid peroxidation.

3. Resolves Phlegm and Relieves Cough

Xinhui Chenpi is a traditional Chinese herbal medicine that enters the Lung meridian and supports cardiopulmonary function. It is particularly effective in treating cough, wheezing, and excessive phlegm caused by Lung-heat. When needed, Xinhui Chenpi may be decocted together with other herbs such as Anemarrhena rhizome (Zhimu), Fritillaria bulb (Beimu), and licorice root (Gancao).

4. Regulates Qi and Strengthens the Spleen

Xinhui Chenpi regulates Qi and fortifies the Spleen and Stomach. Its volatile oil components mildly stimulate the gastrointestinal tract, helping expel accumulated intestinal gas. Meanwhile, its acidic constituents and volatile oils promote gastrointestinal motility and enhance digestive and absorptive functions—exerting a mild inhibitory effect on ulcer symptoms.

Precautions When Consuming Chenpi

1. Chenpi has drying and heat-promoting properties; thus, individuals with internal heat or those suffering from Liver-Spleen Qi deficiency should avoid consuming it.

2. When preparing soups or congee with Chenpi, add it to cold water before heating—this preserves its warming/drying effect. Adding it directly to boiling water diminishes this property.

3. Patients with Yin-deficiency cough or throat phlegm should avoid combining Chenpi with Pinellia (Banxia) or Arisaema (Nanxing).

4. Fresh tangerine peel lacks the therapeutic benefits of aged Chenpi. The aging process reduces volatile oil content while increasing flavonoid compounds—thus, the longer Chenpi is stored, the more pronounced its medicinal effects become.
