concentrated principle, Macrotin,
one-eighth to one-half grain.

Blood-root. ]

BLOOD-ROOT (_Sanguinaria Canadensis_), is also known as Red Puccoon. The
part used is the root. In minute doses Blood-root is a valuable
alterative, acting upon the biliary secretion and improving the
circulation and digestion. _Dose_--Of powdered root, one-fourth to
one-half grain; of tincture, one to two drops; of the fluid extract,
one-half to one drop. When given in a fluid form it should be well
diluted.

BURDOCK (_Arctium Lappa_). The root is the part used. Burdock is a
valuable alterative in diseases of the blood. _Dose_--Of tincture, from
one teaspoonful to a tablespoonful twenty minutes before meals; of fluid
extract, one to two teaspoonfuls.

BLUE FLAG (_Iris Versicolor_). The part used is the root. _Dose_--Of the
tincture, five to ten drops; of fluid extract, three to ten drops; of
concentrated principle, Iridin, one-half to two grains.

SWEET ELDER (_Sambucus Canadensis_). Sweet Elder-flowers are a valuable
alterative, diuretic, mucous and glandular stimulant, excellent in
eruptive, cutaneous, and scrofulous diseases of children. An infusion,
fluid extract, or syrup, may be used in connection with the "Golden
Medical Discovery." Both will be found valuable for cleansing the blood
and stimulating the functions to a healthy condition. _Dose_--Of the
infusion of the flowers, from one-half to one ounce, if freely taken,
will operate as a laxative; of fluid extract, one-fourth to one-half
teaspoonful. The flowers, or inner bark of the root, simmered in fresh
butter, make a good ointment for most cutaneous affections.

IODINE. This agent, in the several forms of Iodide of Potassium, Iodide
of Ammonium, Iodide of Iron, and Iodide of Lime, is largely employed by
physicians, and often with most happy results. But for domestic use we
cannot advise its employment, as it is liable to injure the invalid,
when its action is carried too far, which is apt to be the case, when
not administered under the supervision of a competent physician.

MERCURY. The various preparations of mercury have a profound, alterative
effect upon the system. When taken for some time, they change the
quality and composition of the blood; cause a diminution in the number
of red blood-corpuscles, and an increase in the various effete
materials. In the vast majority of cases we prefer the vegetable
alteratives, but in rare instances they
