Pinyin Name: Yì Zhì Rén (or Yì Zhì)
English Name: Sharpleaf Galangal Seed
Latin Name:Semen Alpiniae Oxyphyllae Property and Flavor: Warm in nature, pungent in taste
Brief Introduction:Semen Alpiniae Oxyphyllae is the dried, ripe seed of Alpinia oxyphylla Miq., used to warm the spleen and kidney for the treatment of (1) chronic diarrhea accompanied by cold and abdominal pain, and (2) enuresis, frequent urination, and seminal emission. The herb is commonly known as Semen Alpiniae Oxyphyllae, Sharpleaf Galangal Seed, or Yì Zhì Rén.
Botanical Source: Common herbal works and other authoritative materia medica works define Yi Zhi Ren (Sharpleaf Galangal Fruit) as the fruit of Alpinia oxyphylla Miq., a species of the Zingiberaceae family (ginger family), genus Alpinia, order Zingiberales (formerly in order Scitamineae). This widely used species is described below:
(1) Alpinia oxyphylla Miq.
Botanical Description:Alpinia oxyphylla Miq. is a perennial cespitose herb of the Zingiberaceae family (ginger family) and genus Alpinia. It is commonly known as Yì Zhì ("benefiting wisdom"). The plant grows up to 1–3 m tall. Petioles are short; stems are thick; rhizomes are short, 3–5 cm long.
Leaf blades are lanceolate, 20–35 cm long and 3–6 cm wide; apex is caudate-acuminate; base is broadly cuneate; margin bears deciduous setulae (setiform), with dentate residual traces; both surfaces are glabrous; paraphyll (ligule) is membranous and 2-lobed, 1–2 cm long (rarely up to 3 cm), covered with pale brownish (hazel) pilose hairs.
Racemes are terminal, 8–15 cm long, enclosed and concealed within sheathing phyllaries; inflorescence axis bears very short pubescence; pedicels are 1–2 mm long; bracts are membranous and brownish; calyx is tubular, ~1.2 cm long, shallowly 3-dentate at the apex, deeply dehiscent on one side, and externally pubescent; corolla tube is nearly equal in length to the calyx tube, with 3 oblong lobes (~1.8 cm long); the superior lobe is slightly larger, slightly pouch-shaped at the apex, white, and externally pubescent; labellum is obovate, ~2 cm long, pink with red striations, and crisped at the apical margin; lateral staminodes are conical, ~2 mm long; there is 1 stamen; filaments are flat and linear (filiform), ~1.2 cm long; anthers are ~6–7 mm long; the apical portion of the septum bears circular, comb-like appendages; ovary is inferior and densely tomentose.
Capsules are spherical (globular) or elliptical when fresh, becoming fusiform (spindle-shaped) upon drying; pericarp exhibits conspicuous vertical vascular lines; fruits measure 1.2–2 cm in length and ~1 cm in diameter; they are indehiscent and turn yellowish-green or creamy yellow at maturity. Seeds are numerous, irregularly oblate (discoid), and covered with a pale yellow aril. Flowering occurs from February to April; fruiting from May to August.
Ecological Environment:Alpinia oxyphylla Miq. grows in damp, shaded forest habitats. It is native to and mainly distributed in China, and is also cultivated commercially.
Growth Characteristics:Alpinia oxyphylla Miq. prefers a warm, humid climate. The mean annual temperature in its primary production regions is 24–25 °C (75.2–77.0 °F); mean monthly temperature ranges from 18–30 °C (64.4–86.0 °F); flowering-period temperature is 24–26 °C (75.2–78.8 °F); annual precipitation exceeds 1,800–2,000 mm. The plant thrives in partial shade (40–50% light reduction) and requires relative humidity (RH) >80%. However, it can also tolerate unshaded, moist sites. Optimal cultivation substrates include loose, fertile, slightly acidic sandy loam or loam; humus-rich forest soil (sylvestris soil) is ideal.
Characteristics of the Herb: The dried fruit is fusiform (spindle-shaped) or elliptical, with both ends acuminate; it measures 1.2–2 cm in length (or 1.5–2 cm) and 1–1.2 cm (or 1–1.3 cm) in diameter. The surface is gray, reddish-brown to taupe (grayish brown), bearing 13–18 (or 13–20) uneven, vertical, intermittent, protuberant lines. Perianth remnants are present at the apex, and a carpopodium (fruit stalk) or fruit stalk scar remains at the base. The pericarp is thin and slightly tough, adhering loosely to the seed. The seed mass contains a hazel (pale brown) septum and is divided into three locules, each containing 6–11 seeds. The seeds are irregularly polyhedral, slightly blunt, approximately 3–4 mm in diameter and 1.5 mm thick; their surface is taupe (grayish brown) or sallow (grayish yellow), and each is enveloped by a faint yellow (pale yellow) membranous aril. The hilum is centrally located on the ventral surface, slightly concave, with a groove-like raphe extending from the hilum to the junction of the dorsal surface. When broken, the interior is white and mealy. The herb has a distinctive aromatic fragrance and tastes pungent and slightly bitter.
Pharmacological Actions: (1) Cardiotonic effect; (2) Calcium antagonistic activity on the rabbit aorta; (3) Anti-gastric injury effect; (4) Inhibition of prostaglandin synthesis; (5) Increase in peripheral white blood cell count in mice.
Medicinal Efficacy: Warming the kidney, controlling nocturnal emission, arresting polyuria, warming the spleen to relieve diarrhea, consolidating saliva, consolidating Qi, and restraining seminal emission. It is indicated for enuresis due to kidney deficiency, frequent urination, spermatorrhea and leukorrhea, deficient cold of the spleen and stomach, spleen-cold diarrhea, abdominal cold pain, abdominal pain caused by cold pathogen, vomiting, syncope due to cold pathogen, syncope due to pathogenic cold and vomiting diarrhea (vomiting and diarrhea due to pathogenic cold syncope), diarrhea and loose stools, excessive salivation, dribbling urine, kidney-deficiency enuresis, frequent micturition, and nocturnal polyuria (frequent urination at night).
