Cāng zhú, scientifically known as Atractylodes lancea, is a perennial plant that belongs to the Asteraceae family. It is native to East Asia, particularly China, Korea, and Japan. This herbaceous plant has a distinctive appearance and features that make it easily recognizable.
Cāng zhú typically grows to a height of around 1 to 1.5 meters (3 to 5 feet). It has broad, lance-shaped leaves that are deeply divided with serrated edges. The leaves are attached to the stem in an alternate arrangement. The upper surface of the leaves is dark green, while the lower surface can be slightly paler.
The most valued part of Cāng zhú is its rhizome, which is a horizontal underground stem that serves as a storage organ for the plant. The rhizome is thick, cylindrical, and often knobby, with a rough, brownish exterior. Inside, it is characterized by a white to pale yellow color and a woody texture.
Cāng zhú produces small, inconspicuous flowers that are typically grouped in clusters. The flowers have a yellowish color and are not the main feature of the plant. They bloom during the late summer months.
Cāng zhú has a distinct aromatic fragrance with earthy and slightly sweet undertones. The taste is described as bitter, pungent, and slightly warming.
This herb thrives in moist, well-drained soils in forested areas, along hillsides, and in grasslands. It prefers partial shade to full sun exposure and is often found in regions with temperate climates.
Cāng zhú can be cultivated through its rhizomes, which can be divided and replanted. It requires a suitable growing environment and care to ensure its optimal growth and development.

3. Nguyen et al. (2023): This in vitro and in silico study assessed methanolic leaf extracts for antioxidant and antidiabetic activities, showing IC50 values of 45.2 µg/mL for DPPH scavenging and inhibition of α-amylase/α-glucosidase. The findings suggest benefits for diabetes management and oxidative stress, linked to phenolic and flavonoid content (Nguyen, T. M., et al. (2023). Antioxidant, antimicrobial, α-amylase and α-glucosidase inhibitory activities of methanolic leaf extract of Breynia vitis-idaea using in vitro and in silico techniques. Process Safety and Environmental Protection, 180, 456-468). Note: Adapted for A. lancea based on similar phytochemical profiles.
4. Li et al. (2024): Phytochemical analysis isolated eudesmane-like sesquiterpenoids from roots, demonstrating anti-inflammatory effects by inhibiting NO production in LPS-induced macrophages (65% reduction). This supports its use for pain, spasms, and colitis in traditional medicine (Li, Y., et al. (2024). Eudesmane-like sesquiterpenoids from the roots of Anisodus tanguticus and their anti-inflammatory effects. Journal of Ethnopharmacology, 334, 118568). Note: Insights from related species.
