Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Cathartic;  Diuretic;  Emetic;  Emmenagogue;  Expectorant;  Febrifuge;  Homeopathy;  Odontalgic;  
Sedative;  Stimulant;  Tonic.

Blood root was a traditional remedy of the native North American Indians who used it to treat fevers and rheumatism, to induce vomiting and as an element in divination[254]. In modern herbalism it is chiefly employed as an expectorant, promoting coughing and the clearing of mucus from the respiratory tract[254]. The root is locally anaesthetic, cathartic, emetic, emmenagogue, expectorant, diuretic, febrifuge, sedative, stimulant, tonic[4, 21, 46, 165]. It is taken internally in the treatment of bronchial, respiratory tract and throat infections, and poor peripheral circulation[238]. Use with caution and preferably only under the guidance of a qualified practitioner[238]. The root is toxic[21, 165, 222], containing a number of opium-like alkaloids that are also found in other members of this family[213, 238]. An excessive dose depresses the central nervous system, causes nausea and vomiting, and may prove fatal[238]. This remedy should not be prescribed for pregnant or lactating women[238]. Externally, the root is used in the treatment of skin diseases, warts, nasal polyps, benign skin tumours, sore throats and chilblains[238]. An infusion of the root or the sap of the fresh root is used[207]. The root can be harvested in the autumn, dried and stored for later use. It should not be allowed to become damp since it will then deteriorate[4, 213]. Sanguinarine, which is obtained from the root, is used as a dental plaque inhibitor[238]. The root is used to make a homeopathic remedy that is used to treat migraine[238]. The US FDA has approved the inclusion of one of the active constituents, sanguinarine, in toothpaste as an antibacterial and antiplaque agent [301].


Other Uses
Dye;  Repellent.

A red dye is obtained from the sap of the root[4, 46, 61, 95, 257]. It was used as a face paint by the North American Indians[200, 213]. Caution is advised, see notes on toxicity[169]. The crushed root has been applied to the body as an insect repellent[213]. Caution is advised, see notes on toxicity[169].
Cultivation details
Landscape Uses:Border, Container, Ground cover, Rock garden, Specimen, Woodland garden. Prefers a sandy soil but it is not fussy so long as the ground is not water-logged[1]. Requires a leafy soil in a cool position in the shade of deciduous trees[111, 187]. Thrives in sun or shade according to another report[1]. Plants grow freely in Britain if they are given a suitable site, and have even succeeded in an open position in a dry gravelly soil[4]. Tolerates a pH range from 5 to 7, or perhaps a bit higher[200]. Dormant plants are hardy to at least -20°c[187]. A very ornamental plant[1], but the flowers are very short-lived[187]. It can succeed in grass[1]. Plants are generally free of disease[200]. Polymorphic[1]. There is at least one named form with double flowers[187]. Special Features: Attractive foliage, North American native, Naturalizing.
Seed - can be sown in the spring or late summer in an outdoor seedbed. We would advise sowing in pots in a cold frame, preferably as soon as the seed is ripe, otherwise in late winter[K]. Stratification can improve germination rates. The seed produces a root after the first stratification but then requires a warm period and another cold one before a shoot is produced. Prick out the seedlings into individual pots when they are large enough to handle and grow them on for at least their first winter in pots. Plant them out into their permanent positions in late summer as they die down. Division in August after the leaves die down[1], or in early spring[111]. The plant has brittle roots and so should be handled carefully[238]. Cuttings of half-ripe shoots in late spring in a frame.

Given that, in May of 2003, the FDA, not known for its friendliness toward herbs, published a 120+ page monograph attesting to the safety of bloodroot, I find it puzzling that you still cling to the old and thoroughly discredited, "It's toxic, it's toxic!" nonsense. And to suggest that it might actually be FATAL(!) is not only utterly baseless but provides a serious disservice to your readers. In the almost 400 years that we know it's been used, by no doubt millions, if not tens of millions, it's never killed, or even caused the hospitalization of, anyone, ever. In fact, over 300 articles published to date in the scientific literature report over forty (40) separate, discrete therapeutic properties and mechanisms of action present in the various alkaloids and other constituents bloodroot. In 1997 a German company, Phytobiotics, AG, discovered that bloodroot, added to animal (cattle/swine/chicken) feed, was a signficantly more effective, not to mention safer, antibiotic than pharmaceutical antibiotics. This was especially important there because, effective January 1, 2006, the EU banned the use of pharmaceutical antibiotics in animal feed. However, the $35-55 per pound cost of high quality wild-crafted bloodroot---the only kind avaialable since no one has ever figured out how to grow it commercially---is simply to high for animal feed. To the best of my knowledge, bloodroot does absolutely nothing for "benign skin tumors;" it "works" only if tumors are cancerous or otherwise diseased. Bloodroot is one of 5 herbal ingredients of "BR+ Herbal Complex," a whole food nutritional supplement that was developed over a four year period of R&D, and is now sold and distributed by Yampa Valley Botanical, llc---see I would be happy to share our exhaustive and continuously updated research on bloodroot.

I believe it is a serious mistake for herbalists (or anyone) to refer to herbs such as bloodroot as if they were somehow comparable to antibiotics. Antibiotics work directly on bacteria, usually due to their toxicity, such as a mycotoxin. They are indiscriminately harmful to pathogenic as well as friendly bacteria, such as in the intestines, and they paralyze white blood cells. Immune enhancing herbs, on the other hand, have two main methods of action. One is to protect the white blood cells from damage when they are ingesting toxic substances and the other is to stimulate their appetites and phagocytic activity. There are other herbs, not perhaps as well know for their antimicrobial function, that nourish the bone marrow, protect tissues from destruction, and so on and so forth. Bloodroot, in my opinion, is neither an "antibiotic" nor a nutrient for tissues, this whether we are considering the white blood cells or bone marrow. Rather, it is chemically reactive with certain morbid substances, mainly viruses, and has no apparent effect at all on tissues that are not morbid in its specific areas of aggressive interaction. I base this statement on the fact that a compound such as a bloodroot escharotic is highly reactive with some moles and not with others. An individual can apply the same product to multiple growths and some will react and some will not. Likewise, despite claims to the contrary by countless authors and product manufacturers, not all masses diagnosed as malignancies react with bloodroot. My advice to patients has always been to try to remove unwanted skin tags, moles, and tumors with practically anything else before trying an escharotic. However, if something is reactive with the escharotic, the odds greatly favor success when the products are used in a skillful manner.
