Latin: Eriobotrya japonica
The fruit of the subtropical plant Eriobotrya japonica (Thunb.)Lindl., of the Rose (Rosaceae) family, it is related to the apple and other well-known fruit trees of the temperate zone. Ornamental in appearance and rarely more than 10 metres in height, the evergreen loquat is frequently planted in parks and gardens.

The leaves, clustered toward the ends of the branches, are thick and stiff, elliptic to lanceolate in form, 200íV250 mm in length, with coarsely serrate margins. The fruits are borne in large, loose clusters; individually they are round, obovoid, or pear-shaped, 25íV75 mm in length, with a tough, yellow to bronze, plumlike skin enclosing juicy, whitish to orange-colored flesh surrounding three or four large seeds. The flavor is agreeably tart, suggesting that of several other fruits of the same family.

Though its native home is probably central eastern China, the loquat tree was introduced into Japan, where it was much developed horticulturally and is still highly valued. Some superior Japanese varieties reached Europe, the Mediterranean area, and a few other regions. The loquat is grown commercially (usually on a rather small scale) in many subtropical regions. They grow well on various soils, from sandy loams to clays, and come into bearing at three or four years.

The fruit is produced in winter and early spring, it is up to 4 cm in diameter. The leaves are harvested as required and can be used fresh or dried. The hairs should be removed from the leaves in order to prevent irritation of the throat.

The fruit, kernel and tender leaves are all used for medicinal purposes.
Sweet, slightly sour in flavor, cool in nature, it is related to the channels of the lung and stomach. The immature loquat fruit is sour in flavor, and is related to the liver channel.
Moistens the lungs and relieves coughing, promotes the secretion of body fluids and eliminates thirst, soothes the stomach and pushes down the uprising qi, pacifies the liver and clears heat.

The tender leaves, free of hair, are antitussive (cough suppressant) and eliminate sputum.

It is reported in "Eating Your Way to Health" that a group of 167 cases taking this recipe, 42 (25 percent) were clinically controlled, 60 (36 percent) markedly effective, 35 (20 percent) ameliorated, with only 30 (18 percent) ineffective.

Cautions on Use:
The seed is slightly poisonous. This report probably refers to the hydrogen cyanide that is found in many plants of this family. The seed should only be used in small amounts if it is bitter. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.
