Clinical Applications

1. For treating common cold with fever, cough, sore throat, dry mouth and thirst, and vitamin C deficiency (scurvy): Use 10–30 fresh (amla) fruits each time, decoct in water, and drink the decoction. (Guangzhou Military Region, *Manual of Common Chinese Herbal Medicines*)

2. For diphtheria: (Yunnan) 500 g of olives, 30 g each of Scrophularia root and licorice root. Soak in cold boiled water until a frost-like substance forms; collect the substance, spread it out on cotton paper, and sun-dry. Then mix with 6 g of Gentiana macrophylla powder, 1.5 g of borneol, and 1.5 g of roasted ginkgo nut powder, and apply to the throat.

3. For asthma: (Yunnan) 21 olives. First, boil pork heart and lungs; skim off the scum, then add the olives and cook until tender. Consume the olives along with the broth. (Formulas 2–3 are from *Commonly Used Folk Herbs of Kunming*)

Crude Drug Identification

Identification

1. The powder of this product is pale brownish-yellow. The epidermal cells of the exocarp are irregularly polygonal or nearly square, with thick walls. The palisade cells of the seed coat appear polygonal in surface view and nearly rectangular in cross-section; they are densely arranged, with a diameter of 53–96 μm, extremely thick walls, fine and dense pores and grooves, and distinct cell cavities.Fibers occur singly or in clusters of several, are elongated, 12–29 μm in diameter, with both ends mostly rounded and blunt; their walls are thick and lignified, and some cell cavities contain a yellowish-brown substance. Stone cells are circular-triangular or irregular in shape, 17–75 μm in diameter, with thick walls and distinct pore channels. Calcium oxalate cluster crystals are 7–66 μm in diameter, and calcium oxalate prismatic crystals are also visible.

2. Take 0.5 g of the powdered sample, add 20 mL of ethanol, subject to ultrasonic treatment for 20 minutes, filter, and evaporate the filtrate to dryness. Dissolve the residue in 20 mL of water, add 30 mL of ethyl acetate, and shake to extract. Take the ethyl acetate solution, evaporate to dryness, and dissolve the residue in 1 mL of methanol to prepare the test solution.Separately, take 0.5 g of Amla reference material and prepare a reference material solution using the same method.Test by thin-layer chromatography (General Chapter 0502): Pipette 2–4 μL of each of the two solutions and apply them separately onto the same silica gel G plate. Develop with a mobile phase of chloroform–ethyl acetate–methanol–formic acid (9:9:3:0.2), remove the plate, and allow it to air-dry.spray with a 10% ethanol solution of sulfuric acid, and blow with hot air until the spots become clearly visible; then examine under a UV lamp (365 nm). In the chromatogram of the test sample, fluorescent spots of the same color appear at positions corresponding to those in the reference herbal material chromatogram.

Properties of Crude Drugs

The fruit is spherical or flattened-spherical, with a diameter of 1.2–2 cm. The surface is brownish to dark green, with pale yellow granular protrusions, wrinkles, and indistinct six ridges. The fruit stalk is approximately 1 mm long, and the pulp (mesocarp) is 1–4 mm thick, hard and brittle.The endocarp is yellowish-white, hard and nut-like, with a slightly 6-angled surface; several vascular bundles are present in the upper part of the dorsal suture, and it splits into 6 segments when dried. There are 6 seeds, which are nearly triangular in shape and brown. It has a faint odor and a sour, astringent taste with a lingering sweetness. Those that are large, thick-fleshed, and have a strong lingering sweetness are considered superior.

Botanical Information

Botanical Classification

Emblica, a plant of the genus Emblica in the Euphorbiaceae family.

Morphological Characteristics

A deciduous small tree or shrub, 3–8 m tall.The bark is grayish-white, thin, and easily peeling, exposing large patches of reddish-brown inner bark. Leaves are alternate on slender twigs, arranged in two rows, densely packed, and closely resembling pinnate compound leaves; they are nearly sessile; when the leaves fall, the entire twig is shed; stipules are linear-lanceolate; leaf blades are oblong-linear or linear-oblong, 1–2 cm long, and 3–5 mm wide.Flowers are clustered in the leaf axils; they are small and yellow; unisexual, with both male and female flowers on the same plant, and bear short pedicels; each cluster contains one female flower; each flower has 5–6 sepals and no petals; the disk of the male flower consists of 6 minute glands, and the 3 stamens are fused into a column; the disk of the female flower is cup-shaped with a lacerated margin, and the ovary is partially concealed within it.The fruit is fleshy, about 1.5 cm in diameter, round with slightly six-angled edges; it is initially yellowish-green and turns reddish-brown when ripe, with a taste that is initially sour and astringent but becomes sweet. Flowering occurs from April to May, and fruiting from September to November.

Distribution Area

It is distributed in Fujian, Taiwan, Guangdong, Hainan, Guangxi, Sichuan, Guizhou, Yunnan, and other regions.

Growth Habits

It prefers a warm and humid climate and is sensitive to cold; frost can easily cause leaf and flower drop and may even freeze and damage young shoots. It is not particular about soil type and can be grown on various types of mountainous terrain in southern China. It is best cultivated on sunny slopes, terraced fields, and orchards.

Propagation Methods

Propagated by seeds and grafting.

Cultivation Techniques

1. Seed Propagation: Sow seeds in spring to raise seedlings. Once the seedlings reach 70–100 cm in height, they can be grafted onto superior varieties.

2. Grafting: Select 2–4-year-old wild amla trees as rootstocks and use 2-year-old branches from high-quality cultivars as scions for grafting between February and May. After the grafts take root, transplant the trees at a spacing of 4 m × 3 m or 4 m × 4 m, with 600–825 trees per hectare.

Pest and Disease Control

Pests include the wood-boring moth, scale insects, and aphids; these can be controlled by spraying with 0.1%–0.8% methamidophos or similar pesticides.
