Medicinal Part: The dried pericarp (fruit peel) of Areca catechu L., a plant belonging to the Arecaceae (palm) family.
Morphological Characteristics: Areca Peel typically appears as slightly oval or elongated ovate, scoop-shaped pieces. They measure approximately 1.6 to 6.9 inches (4–17.5 cm) in length, 0.8 to 1.2 inches (2–3.125 cm) in width, and 0.08 to 0.5 inches (0.2–1.25 cm) in thickness. The outer pericarp ranges from deep brown to almost black, exhibiting irregular longitudinal wrinkles and noticeable raised transverse patterns. At the top, remnants of the pistil are visible, while the base often shows traces of the fruit stalk and persistent sepals. The inner pericarp is concave, brown or dark brown, smooth, and rigid like a shell. The peel is lightweight yet hard; when torn lengthwise, the fibrous mesocarp is visible. It possesses a subtle aroma and a mildly astringent taste.

Functions and Indications of Areca Peel
Core Functions: Areca Peel is traditionally utilized to promote the smooth flow of Qi (vital energy) and alleviate abdominal discomfort. It also works to facilitate fluid metabolism and reduce various forms of swelling (PMID: 29074697).
Key Indications: It is primarily indicated for conditions characterized by dampness obstructing Qi circulation, which can manifest as abdominal bloating and fullness, sluggish or unsatisfactory bowel movements, generalized edema and swelling throughout the body, swelling in the legs (sometimes associated with beriberi), and difficulty with urination (PMID: 35017058).
Traditional Combinations with Areca Peel
1. For treating chronic skin conditions such as ringworm and scabs: Fresh or dried Areca seeds (with the entire peel intact and undamaged) are steeped in approximately one liter of wine. This mixture is then slowly simmered over low heat until dry, ground into a fine powder, and combined with rendered pork lard for topical application. (As recorded in *Sheng Ji Zong Lu* [The Compendium of Holy Benevolence])
2. For treating pediatric wind-phlegm obstruction presenting with inability to speak, shortness of breath, wheezing, and limb tremors: Equal parts of Terminalia chebula (half raw, half prepared by roasting, with seeds removed) and Areca Peel are decocted in water. This specific formula is known as "Er Sheng San" (Two Sages Powder). (From *Quan You Xin Jian* [Comprehensive Mirror for Young Children's Health])
Precautions and Contraindications for Areca Peel
Important Safety Note: Individuals with Qi deficiency or a generally weak constitution should use Areca Peel with caution. As with any herbal remedy, it is paramount to consult a qualified practitioner of Traditional Chinese Medicine before incorporating Areca Peel into your health regimen, especially if you have pre-existing health conditions or are currently taking other medications (PMID: 15302671).
