Cāng zhú (Atractylodes lancea) is a traditional Chinese medicinal herb known for its significant role in traditional Chinese medicine. It is primarily used to treat various ailments, including digestive disorders, excessive moisture, and certain immune-related conditions. The plant belongs to the Asteraceae family and is characterized by its lance-shaped leaves and aromatic rhizomes.

Description

Atractylodes lancea is a perennial plant that grows to a height of approximately 30-60 cm. It has lance-shaped leaves and produces small, yellowish flowers. The most valuable part of the plant is its rhizome, which is harvested in autumn. The rhizome has a strong, distinctive aroma and is commonly used in dried form for medicinal purposes.

Traditional Uses

In Traditional Chinese Medicine, Cāng zhú is valued for its ability to dry dampness and strengthen the spleen, making it a key remedy for conditions related to dampness and spleen deficiency. It is often used in cases of diarrhea, fatigue, and edema. Additionally, Cāng zhú is believed to have diuretic properties, helping to remove excess water from the body.

Cāng zhú is also used to treat night blindness and to improve vision, attributed to its liver-nourishing properties. Furthermore, it is considered to have immune-modulating effects, potentially enhancing the body's resistance to certain diseases.

Recent studies have shown that Cāng zhú contains several bioactive compounds, including volatile oils, sesquiterpenes, and polysaccharides.
