Brief introduction: The herb Radix Ophiopogonis is the dried tuberous root of Ophiopogon japonicus(Thunb.) Ker-Gawl., used (1).to replenish and promote fluid production for the treatment of dipsosis, dry throat, dry cough, and bloody sputum in cases of acute febrile diseases and Yin deficiency of the lung and stomach, and (2).to calm the mind for the treatment of fidgetiness and insomnia. The herb is commonly known as Radix Ophiopogonis, Dwarf Lilyturf Root, Mài Dōnɡ.
Botanical source: Herbal classic book defined the herb Dwarf Lilyturf Tuber(Mai Meng Dong) as the tuber of the Liliaceae family plant species:(1). Ophiopogon japonicus(L.f.) Ker-Gawl., or (2). Ophiopogon bodinieri Levl. They are plant species of the Ophiopogon KerGawl genus, the Liliaceae family (lily family) of the Liliales order. These 2 commonly used species are introduced:
Botanical description: The Ophiopogon japonicus(L.f.)Ker-Gawl., is a plant of the Liliaceae family (lily family) and Ophiopogon(lilyturf) genus, some latest classification system classified the herb into Asparagaceae family (asparagus family), it is commonly known as "Dwarf Lilyturf", or "Mài Dōnɡ" or "Mài Mén Dōnɡ". Perennial herb, it grows up to 12~40 cm high, fibrous root often formed in the middle or apex is swollen. Leaves are connate; petiole is sheathlike, the margin is membranous; the blade is narrowly linear, basal leaves are with many fibrous old leaves, leaf length is 15~40 cm, width 1.5~4 mm, apex is pointed or acuminate, base is greenish-white and slightly enlarged. Scapes are shorter than leaves, 7~15 cm long, spicate racemes are racemble, terminal, 3~8 cm long, bracteoles are membranous, 1~3 flowers per bracts axillary; pedicels are 3~4 mm long, jointly located at mid-fold or nearly central; flowers are small, lavender, slightly drooping, 6 perianth segments, not spreading, lanceolate, ca. 5 mm, 6 stamens, anthers are triangular-lanceolate; Style is about 4 mm, broad base, slightly conical. Berry is spherical, diameter is 5~7 mm, early green, dark blue after ripening. Its flowering period is from May to August, fruiting from July to September.
The root is thicker, often swollen into the middle or near the end of the oval or spindle-shaped small roots; small root length is 1~1.5 cm, or longer, 5~10 mm wide, light brown; underground walking stems are slender, diameter is 1~2 mm, the membranous sheath on the day. The stems are very short, leaf base to generate plexus, leafy, 10~50 cm long, a few is longer, 1.5~3.5 mm wide, with 3~7 veins, edges are serrulate.
Scapes are 6~27 cm long, usually much shorter than leaves, racemes are 2~5 cm long, sometimes longer, with several to ten flowers; flowers are solitary or paired bracteoles lanceolate, apex is acuminate, the lowermost length is up to 7~8 mm; pedicel is 3~4 mm long, the joints are located in the middle of the middle or above; perianth often sag and Not spreading, lanceolate, ca. 5 mm, white or lavender; anthers are triangular-lanceolate, 2.5~3 mm long; style 4 mm, coarser, 1 mm wide, base broadly attenuate upwardly. Seeds are spherical, 7~8 mm in diameter. Its flowering period is from May to August, fruiting from August to September.
Therefore, plant body changes greatly, for example, densely foliar plexus, leaf width 4 and sometimes narrowly different significantly; but its flower structure changes little, especially the perianth in the flower bloom is only slightly open, style is basal wide, generally slightly thicker and shorter, slightly conical and other traits are consistent, is to identify the main features of this species.
Ecological Environment: The Ophiopogon japonicus(L.f.) Ker-Gawl., grows at the area with an altitude below 2,000 meters, on the slopes of the grass, in the forest, or beside the stream.

Ker-Gawl., prefers warm and humid, abundant rainfall climate conditions, grows in 5~30 °C (Celsius, or 41~86 degrees Fahrenheit), the optimum growth temperature is 15~25 °C (Celsius, or 59~77 degrees Fahrenheit), stop growing at a temperature below 0 °C (Celsius, or 32 degrees Fahrenheit) or above 35 °C (Celsius, or 95 degrees Fahrenheit), demand enough water during growth and require adequate light, especially in the blooming period of roots, sufficient light to promote the expansion of roots.
Dwarf Mondo Grass, Ophiopogon japonicus, is an ornamental grass that grows to 4" in height and is closely related to the liriope. It is also known as Dwarf Lilyturf, Mondo Grass Dwarf, and Monkey Grass. This perennial evergreen grows in average, medium wet, well-drained soil in part shade to full shade. It spreads by underground stems or tubers. This plant is widely used in rock gardens, seashore plantings, borders, and groundcovers. It is intolerant of the full sun.
Dwarf Mondo Grass is a beautiful clumping dark grass that typically grows anywhere from four to six inches tall; the variety Nana grows just three-inches tall. Ornamental grass is ideal for low traffic plantings, rather than a grass you might use to create a lawn, Dwarf Mondo is also known as Dwarf Lilyturf, Mondo Grass Dwarf, and Monkey Grass.
Mondo Grass is native only to China, is not a grass but a lily. This perennial evergreen grows in dense, slowly spreading clumps, preferring average, medium wet, well-drained soil in filtered sun to full shade, it is intolerant of full sun. It spreads by underground stems or tubers and can be easily propagated by division.
Dwarf Mondo is hardy and will tolerate extremely dry conditions like those seen in Davis and is still frost tolerant to -15 °C (Celsius, or 5 degrees Fahrenheit). The leaves of Dwarf Mondo are somewhat finer than seen in other species and any blooms are hidden. Giant Mondo (O. jaburan) has longer, broader leaves, and the flowering stems can be up to 60 cm (2') long, it is more clump-forming, tolerates only light frosts, and has a weeping habit. Black Mondo (O. planiscapus "Nigrescens") has purple-black strap-like leaves.
Characters of herbs: The root tuber is spindle-shaped, with slightly pointed ends, 1.5~3.5 cm in length, the diameter of the middle part is 3~7 mm. The surface is khaki or yellowish-white, with deep irregular fine longitudinal lines, and sometimes one end has a small stele (central cylinder) exposed. The texture of the herb is soft and flexible, the fracture surface is off-white or yellowish-white, translucent, and the stele is small, which can be pulled out when fresh. The herb has a slight fragrance, it tastes slightly sweet and puckery, slightly sticky when chewed. The herb of better grade is big, yellowish-white, translucent, the texture of the herb is soft and sticky when chewed.
