Dà Fù Pí (Areca Peel) is a Chinese medicinal substance. It is the dried pericarp of Areca catechu L., a plant of the Arecaceae family. Its medicinal material is somewhat ellipsoid or long ovate in shape like a scoop, with a dark brown to nearly black outer surface, light in weight, and hard in texture. Depending on the harvesting time, the pericarp peeled from immature fruits collected from winter to the following spring is commonly known as “Dà Fù Pí” (Areca Peel). The pericarp peeled from mature fruits collected from late spring to early autumn is commonly known as “Dà Fù Máo” (Hairy Areca Peel).
