ETTUCE. The Leaves and Seeds.--It smells
strongly of opium, and resembles it in its effects; and its narcotic
power, like that of the poppy heads, resides in its milky juice. An
extract from the expressed juice is recommended in small doses in
dropsy. In those diseases of long standing proceeding from visceral
obstructions, it has been given to the extent of half an ounce a-day. It
is said to agree with the stomach, to quench thirst, to be greatly
laxative, powerfully diuretic, and somewhat diaphoretic.

357. LAMIUM album. WHITE ARCHANGEL, OR DEAD NETTLE. The Flowers.--The
flowers have been particularly celebrated in female weaknesses, as also
in disorders of the lungs; but they appear to be of very weak powers.

358. LAVENDULA Stoechas. ARABIAN STOECHAS, OR FRENCH LAVEN-DER. The
Flowers.--They have a very fragrant smell, and a warm, aromatic,
bitterish, subacrid taste: distilled with water, they yield a
considerable quantity of a fragrant essential oil; to rectified spirit
it imparts a strong tincture, which inspissated proves an elegant
aromatic extract, but is seldom used in medicine.

359. LEONURUS Cardiaca. MOTHERWORT. The Leaves.--These have a bitter
taste, and a pretty strong smell: they are supposed to be useful in
hysteric disorders, to strengthen the stomach, to promote urine; and
indeed it may be judged from their smell and taste, that their medical
virtues are considerable, though they are now rejected both from the
London and Edinburgh Pharmacopoeias.

360. LILIUM candidum. WHITE LILY. The Roots.--These are used in
poultices. The good housewife doctors cut the roots in slices and steep
them in brandy; and they are said to be an excellent remedy for all
bruises and green wounds: for which purposes it is applied by them with
considerable effect.

361. LITHOSPERMUM officinale. GROMWELL. The Seeds.--These are roundish,
hard, and of a whitish colour, like little pearls. Powdered, they have
been supposed peculiarly serviceable in calculous disorders. Their taste
is merely farinaceous.

362. LYSIMACHIA Nummularia. MONEYWORT, OR HERB TWOPENCE. The Leaves.--
Their taste is subastringent, and very slightly acid: hence they stand
recommended by Boerhaave in the hot scurvy, and in uterine and other
haemorrhagies. But their effects are so inconsiderable, that common
practice takes no notice of them.

363. MALVA alcea. VERVAIN-MALLOW. The Leaves.--Alcea agrees in quality
with the Altha
