Bloodroot

Christopher Hobbs:

“The bright red rhizome is used to make tinctures and preparations such as salves and ointments for external use.
The fresh herb is strongly acrid and can burn the skin or mucous membranes if applied directly. After drying, it loses some of this effect.
Bloodroot is commonly used in antiseptic mouthwashes and is sometimes recommended by dentists and oral hygienists to help fight plaque and reduce the incidence of tooth decay and gum disease. Scientific studies have supported this use.
The herb is also a popular cancer-fighting remedy for external application. Under the supervision of a qualified herbalist, the tincture and strong bloodroot salve are used for breast cancer, skin cancers, and to remove warts and other growths.”

Bloodroot, a perennial flowering plant native to North America, has been used historically by Indigenous peoples and early herbalists primarily as a remedy for respiratory issues, as an expectorant, and as a topical treatment for skin ailments. Bloodroot’s roots contain potent alkaloids, primarily sanguinarine, which have been the focus of both historical and modern uses.

Historical Uses

Bloodroot was traditionally applied by Indigenous groups for skin conditions, wound care, and respiratory issues. Additionally, it was sometimes used as a dye. Early North American settlers adopted similar practices and believed it to be useful for bronchitis, laryngitis, and other infections.

Modern Clinical Uses (by Herbalists and Naturopaths)

Today, bloodroot is often used in small doses by herbalists and naturopaths, primarily in external applications. It is occasionally used as an ingredient in natural toothpaste and mouthwashes, as sanguinarine has antibacterial properties effective against dental plaque and gingivitis. However, its use is controversial and generally limited due to potential toxicity.

Chemistry

The plant’s primary active compounds are benzophenanthridine alkaloids, especially sanguinarine, chelerythrine, and berberine. Sanguinarine is the most studied of these and exhibits antimicrobial, anti-inflammatory, and anti-cancer properties in vitro.

Pharmacology

Sanguinarine and other bloodroot alkaloids act by inhibiting protein synthesis and cellular respiration in microbes and tumor cells. They exhibit cytotoxic activity that targets rapidly dividing cells, which is the basis for its historical use in treating warts and other skin growths. Bloodroot also has an irritant effect on skin and mucous membranes.

Clinical Trials

Limited clinical trials have focused on bloodroot, primarily examining sanguinarine in dental products for plaque reduction. Some early trials indicated reduced plaque formation and gingivitis, but the data remain inconclusive and do not support widespread use in medicinal contexts. Clinical studies on bloodroot as an anti-cancer agent are still in preliminary stages, as its cytotoxic effects require careful control.

Summary

Bloodroot holds a significant place in historical medicine but is now primarily limited to controlled external use due to its potent, sometimes harmful effects. Its antibacterial and anti-inflammatory properties have contributed to some use in dental care, but internal medicinal use is not widely supported due to toxicity risks. Further clinical research may clarify its potential therapeutic applications, though it remains a restricted substance in most clinical practices due to safety concerns.
