The following table shows the full taxonomy of this plant.

Plant Description and Morphology

Anemarrhena lily is a perennial herb that grows to a height of 30-60 cm, with a rhizomatous root system that spreads horizontally beneath the soil.

Its leaves are long and sword-shaped, typically 10-20 cm in length, with a smooth, grass-like texture and a bluish-green color. The plant produces clusters of small, pale green to white flowers that bloom in late spring to early summer, arranged in racemose inflorescences. The roots are thick, fleshy, and aromatic, often used in traditional herbal medicine for their medicinal properties.

The overall plant has a subtle, sweet scent and a slightly fibrous texture when handled.

Native Habitat and Distribution

Anemarrhena lily is native to the mountainous regions of China, particularly in the provinces of Sichuan, Yunnan, and Guizhou, where it thrives in cool, temperate climates.

It is also found in parts of Southeast Asia, including northern India and Nepal, growing in high-altitude grasslands and forested areas. The plant prefers a climate with distinct seasons, moderate rainfall, and well-drained soil. It typically grows at elevations between 1,500 and 3,000 meters, where temperatures remain cool throughout the year.

Ecological conditions such as partial shade, rocky substrates, and minimal competition from other vegetation are essential for its growth.

Plant Parts Used Medicinally

The primary medicinal parts of Anemarrhena Lily are the rhizomes and roots.

These parts are harvested during the early spring or late autumn when the plant is dormant. The rhizomes are typically cleaned, sliced, and dried for use in traditional herbal preparations. They are often sliced thinly to increase surface area for better extraction of active compounds.

The dried rhizomes are then used in decoctions, powders, or tinctures for their therapeutic properties.

Phytochemical Composition

Anemarrhena Lily contains several active compounds that contribute to its medicinal properties, including alkaloids, saponins, and flavonoids.

Secondary metabolites such as steroidal saponins and glycosides are particularly significant in its pharmacological effects. The plant is known to contain chemical markers like anemarrhenin A and B, which are responsible for its anti-inflammatory and antipyretic activities. These compounds are typically extracted from the rhizomes and roots of the plant.

The specific composition can vary depending on the plant's growing conditions and harvesting time.
