Therapeutic action:
Cathartic, emetic (large doses), tonic diuretic, (lithotriptic), stimulant, detergent, diaphoretic (sudorific), expectorant, cardiac stimulant, hepatic stimulant, depurant.
Bitter root has a slow, persistent and extensive influence on intestinal digestion and elimination, stimulating the secretory functions of the liver (liver tubuli), gall ducts, gall cyst, and also the muscular and mucus coats of the kidneys and bowels. It is excellent for torpid conditions of the bowels, and it will produce a soft stool within 6-8 hours but it is not recommended for irritated or sensitive conditions.
Medicinal uses:
Jaundice, dyspepsia, cardiac dropsy, kidney problems, liver problems, typhoid and other fevers, relaxed bowels, poor digestion, dropsy, worms, syphilis, rheumatism, neuralgia, diabetes, chronic Bright's disease, gall stones, diseases of the joints and mucous membranes, constipation.
Preparation:
Fluid extract, infusion, powder, tincture. The root tends to deteriorate with age.
Dosage:
Large doses are emetic and tend to gripe.
Fluid extract 10-30 drops every 3-4 hours.
Infusion 2-3 tablespoonfuls 6 times daily.
Powder 260 mg. - 2 grams.
Tincture 10-20 drops.
Administration:
Give in smaller and frequent doses as an alterative or tonic; use peppermint, ginger, aniseed, or other carminatives to offset possible griping.
Oral
General tonic, debility, dyspepsia:
Take 5 grains of powder 3 times daily; it has also been used successfully in combination with yellow parilla (Menispermum canadense).

Jaundice:
Give 3-5 drops of fluid extract every 2-3 hours combined with tincture of cayenne or some syrup of ginger, in water, etc.
Cardiac dropsy:
Give 325 mg. - 1 gram of powder 3 times daily.
Formulas:
Liver tonic:
1 1/2 ounces Bitter root, powder (Apocynum androsaemifolium)
1/2 ounce Culver's root, powder (Leptandra virginica)
2 ounces White poplar or quaking aspen bark, powder (Populus tremuloides)
1/4 ounce Ginger root, powder (Zingiber officinale)
2 ounces Golden seal root, powder (Hydrastis canadensis)
1/4 ounce Cayenne fruit, powder (Capsicum annuum; C. frutescens)
Preparation:
Mix the powders well and place in "00" capsules.
Dosage:
1-2 capsules after each meal.
Growth characteristics:
Perennial; found from Canada to Florida to the mid-West; grows best in dry, sandy soils, in fields, thickets, beside roads, lanes, and walls; flowers June-July. It usually grows associated with dog bane or Canadian hemp (Apocynum cannabinum), so it should be distinguished with care (see "Sister Plants").
Drying and preservation:
The root tends to deteriorate with age, so the supply should be renewed each season unless preserved in an appropriate form (fluid extract, tincture, etc.).
Sister plants:
Dogbane or Canadian Hemp or Black Indian Hemp (Apocynum cannabinum; A. pubescens; APOCYNACEAE; LAURACEAE); root; cardiac dropsy, intermittent and remittent fevers, amenorrhea, leucorrhea, emetic (10-30 grains), renal dropsy, dyspepsia; it has similar therapeutic properties and medicinal uses as bitter root, but its action is slightly different; the root bark is often sold for bitter root, but has a yellowish wood, is longitudinally wrinkled, and has no groups of stone cells in the outer bark; bitter root has a more spreading stem, broader leaves, thinner and tougher rhizome with a central pith, thinner bark with groups of stone cells, and the flower is pinkish (rather than dog bane's greenish-white cymes); this should not be substituted for bitter root.
