s of
the Riviera, and when dried they retain the sweet smell of
the flowers. A teaspoonful of these buds is ordered to be infused
in a teacupful of quite hot water, and the liquid to be drunk shortly,
before going to bed. The effect is to induce a refreshing sleep,
without any subsequent headache or nausea. The dried berries may
be had from an English druggist.

[402] A peeled Orange contains, some citric acid, with citrate of
potash; also albumen, cellulose, water, and about eight per cent. of
sugar. The white lining pith of the peel possesses likewise the
crystalline principle "hesperidin." Dr. Cullen showed that the acid
juice of oranges, by uniting with the bile, diminishes the bitterness
of that secretion; and hence it is that this fruit is of particular
service in illnesses which arise from a redundancy of bile, chiefly in
dark persons of a fibrous, or bilious temperament. But if the acids of
the Orange are greater in quantity than can be properly corrected by
the bile (as in persons with a small liver, and feeble digestive
powers), they seem, by some prejudicial union with that liquid, to
acquire a purgative quality, and to provoke diarrhoea, with colicky
pains.

The rind or peel of the Seville Orange is darker in colour, and more
bitter of taste than that of the sweet China fruit. It affords a
considerable quantity of fragrant, aromatic oil, which partakes of the
characters exercised by the leaves and the flowers as affecting the
nervous system. Pereira records the death of a child which resulted
from eating the rind of a sweet China Orange.

The small green fruits (windfalls) from the Orange trees of each
sort, which become blown off, or shaken down during the heats of
the summer, are collected and dried, forming the "orange berries" of
the shops. They are used for flavouring curacoa, and for making
issue peas. These berries furnish a fragrant oil, the _essence de petit
grain_, and contain citrates, and malates of lime and potash, with
"hesperidin," sulphur, and mineral salts. The Orange flowers yield a
volatile, odorous oil, acetic acid, and acetate of lime. The juice of
the Orange consists of citric and malic acids, with sugar; [403]
citrate of lime, and water. The peel furnishes hesperidin, a volatile
oil, gallic acid, and a bitter principle.

By druggists, a confection of bitter orange peel is sold; also a syrup
of this orange peel, and a tincture of the same, made with spirit of
wine, to be given in
