Caodoukou (Round Cardamom)

Alias: Caokou.

Taste and Nature: Pungent in taste, warm in nature.

Meridian Tropism: Primarily affects the Spleen and Stomach meridians.

Medicinal Part: The dried, nearly mature seeds of the plant.

Morphological Characteristics: This herb presents as spherical seed clusters, ranging from 1.5 to 2.5 cm in diameter. The outer surface is grayish-brown, with a distinct yellowish-white septum in the center that divides the cluster into three lobes. Each lobe contains numerous seeds that are tightly adhered. The entire seed cluster feels slightly smooth. Individual seeds are ovoid polyhedra, typically 3-5 mm long and about 3 mm in diameter. They are covered by a delicate, pale brown membranous aril. A longitudinal groove forms the raphe, with the hilum located at one end. The seeds are firm to the touch. When a seed is cut lengthwise along its raphe, the cross-section reveals an obliquely heart-shaped appearance, where the inward extension of the seed coat along the raphe occupies approximately half of the total surface area. The endosperm is grayish-white. Caodoukou possesses an aromatic fragrance and offers a pungent, subtly bitter taste.

Classical Discourses on Caodoukou

1. From the "Clinical Manual of Commonly Used Chinese Herbs": "Caodoukou is pungent and warm, effectively dispersing cold and aromatically transforming dampness. Its primary influence is on the Spleen and Stomach, where it dispels cold and clears dampness from the middle jiao. It also possesses properties to warm the middle jiao and stop vomiting, making it well-suited for conditions caused by cold-dampness obstructing the middle jiao."

2. From "Ben Cao Feng Yuan" (Compendium of Materia Medica): "Caodoukou, being warm in nature, enters the Spleen and Stomach meridians. It is particularly beneficial for cases where wind-cold pathogenic factors settle above the stomach opening, causing pain in the heart area (referring to the epigastric region)."
