3. (Dr Moir.) Angelica root, 2 lbs.; rectified spirit, 1 gall.; make a tincture; to the 'marc' add proof spirit, 1 gall., and repeat the digestion; filter the two tinctures separately, mix, distil off the spirit, and evaporate.

P.) Take 112 lbs. of fresh leaves and tender branches, bruise in a stone mortar or other suitable apparatus, and press out the juice, heat it gradually to 130 F., separate the green colouring matter by a calico filter, heat the strained liquor to 200 F.

to coagulate the alb.u.men, and again filter; evaporate the filtrate by a water bath to the consistence of a thin syrup, then add to it the green colouring matter previously separated, and, stirring the whole together a.s.siduously, continue the evaporation at a temperature not exceeding 140, until the extract is of a suitable consistence for forming pills.--_Dose_, 1/4 to 1/2 gr., gradually increased to 1 or 2 gr.

2. (Ph. E.) Express the juice from the bruised fresh plant, sprinkle the 'marc' with water, and again apply pressure; mix the expressed liquids, filter them, and evaporate the filtered liquor in a vapour bath to the consistence of an extract.

3. (Ph. D.) From the leaves, collected when the plant begins to flower.

The expressed juice is allowed to stand for 24 hours, and the clear portion is decanted; the sediment is placed on a calico filter, washed with an equal bulk of cold water, and the filtrate mixed with the expressed juice. The mixed liquid is next heated in a water bath, to coagulate its alb.u.men, and after being skimmed, and filtered through flannel whilst hot, the washed sediment is added, and the whole evaporated, as before.

4. (Ph. U. S.) The expressed juice is heated to the boiling-point, filtered and evaporated (see _below_).

_Obs._ The P. Cod. directs this extract to be made by two different formulae. The product of the one resembles that of the Ph. L.; that of the other, that of the Ph. E. That of the Ph. L., from retaining the fecula, is the weakest preparation.--_Dose_, 1/2 gr. to 1 gr., gradually increased to 3 or 4 gr.; as an anodyne in neuralgia, tic-douloureux, &c.; as an antispasmodic to relieve rigidity and spasms, in various affections of the uterus, r.e.c.t.u.m, urethra, bladder, &c., and in hooping-cough; in various maladies of the eyes; and as a resolvent and discutient in several glandular diseases. It has been highly recommended as a preservative against scarlet fever. It is most frequently employed externally, under the form of a plaster, ointment, or lotion. It is poisonous.

5. (Alcoholic; E. B. ALCOHOLIc.u.m, L.)--_a._ (P. Cod.) As ALCOHOLIC EXTRACT OF ACONITE--P. Cod.

_b._ (Ph. U. S.) As the last (nearly), using spirit of 935 (=about 13 u.

p.).

_c._ (Moir.) The expressed juice is coagulated by heat, cautiously applied, and filtered; the filtrate is reduced to the consistence of a syrup, and mixed with an equal volume of nearly anhydrous alcohol (say of 90%); the clear portion is lastly evaporated, as before.

_Obs._ The above is much more powerful than the common extract, and is chiefly used in external applications. See BELLADONNA, and _below_.
