they purge almost as strongly as hellebore, in the dose of a dram and a
half; whilst the author above mentioned relates, that he has given a
decoction of two ounces of them as a gentle emetic.

279. SPIGELLA marylandica. WORM GRASS. Root. L. E. D.-About forty years
ago, the anthelmintic virtues of the root of this plant were discovered
by the Indians; since which time it has been much used here. I have
given it in hundreds of cases, and have been very attentive to its
effects. I never found it do much service, except when it proved gently
purgative. Its purgative quality naturally led me to give it in febrile
diseases which seem to arise from viscidity in the primae viae; and in
these cases it succeeded to admiration, even when the sick did not void
worms.

To a child of two years of age who had been taking ten grains of the
root twice a-day without having any other effect than making her dull
and giddy, I prescribed twenty-two grains morning and evening, which
purged her briskly, and brought away five large worms. [Communications

280. TANACETUM vulgare. TANSY. Herb. E. D.--Considered as a medicine, it
is a moderately warm bitter, accompanied with a strong, not very
disagreeable flavour. Some have had a great opinion of it in hysteric
disorders, particularly those proceeding from a deficiency or
suppression of the usual course of nature.

281. TEUCRIUM Marum. CAT THYME. Herb. D.--The leaves have an aromatic
bitterish taste; and, when rubbed betwixt the fingers, a quick pungent
smell, which soon affects the head, and occasions sneezing: distilled
with water, they yield a very acrid, penetrating essential oil,
resembling one obtained by the same means from scurvy-grass. These
qualities sufficiently point out the uses to which this plant might be
applied; at present, it is little otherwise employed than in cephalic
snuffs.

282. TEUCRIUM Chamaedrys. GERMANDER. Herb. D.--The leaves, tops, and
seeds, have a bitter taste, with some degree of astringency and aromatic
flavour. They were recommended as sudorific, diuretic, and emmenagogue,
and for strengthening the stomach and viscera in general. With some they
have been in great esteem in intermittent fevers; as also in scrophulous
and other chronic disorders.

283. TORMENTILLA erecta. TORMENTIL, or UPRIGHT SEPTFOIL. Root. L. E. D.
--The root is the only part of this plant which is used medicinally; it
has a s
