Bloodroot

What is Bloodroot?

Bloodroot (Sanguinaria canadensis) is a perennial flowering plant native to eastern North America, belonging to the poppy family (Papaveraceae). The plant gets its name from the bright red-orange sap that oozes from its rhizome (underground stem) when cut or broken. This distinctive red latex has been used for centuries by Native American tribes for various medicinal and ceremonial purposes.

The primary bioactive compound in bloodroot is sanguinarine, a benzophenanthridine alkaloid that gives the plant its characteristic red color and accounts for most of its biological effects. Other alkaloids present include chelerythrine, protopine, and allocryptopine. While bloodroot has been marketed as a dietary supplement and used in some oral care products, it has become increasingly controversial due to safety concerns.

Health benefits & uses

Oral health (Limited evidence): Bloodroot extract, particularly sanguinarine, has been studied for its antimicrobial properties against oral bacteria. Some research suggests it may help reduce dental plaque and gingivitis when used in toothpastes or mouthwashes. However, most commercial oral care products have moved away from bloodroot due to safety concerns.

Antimicrobial activity (Limited evidence): Laboratory studies have demonstrated that sanguinarine exhibits antibacterial, antifungal, and antiviral properties against various pathogens. However, these effects have primarily been observed in test tubes and petri dishes, with limited clinical evidence in humans.

Skin conditions (No reliable evidence): Historically, bloodroot has been used topically for various skin conditions, including warts and skin tags. However, there is no credible scientific evidence supporting these uses, and topical application can cause severe skin damage and scarring.

Cancer treatment claims (No reliable evidence): Some alternative medicine proponents have promoted bloodroot as a cancer treatment, but there is no scientific evidence supporting its safety or efficacy for cancer therapy. Such use is potentially dangerous and should be avoided.

How it works

Sanguinarine, the primary active compound in bloodroot, works through several mechanisms. It can disrupt bacterial cell membranes and interfere with microbial enzyme systems, which explains its antimicrobial properties. The compound also affects cellular processes in human cells, including protein synthesis and cell division.

At the molecular level, sanguinarine can intercalate with DNA and inhibit various enzymes involved in cellular metabolism. While these properties have generated interest in potential therapeutic applications, they also contribute to the compound’s toxicity concerns, as it can affect both harmful microorganisms and healthy human cells.

Dosage

There is no established recommended daily allowance (RDA) or tolerable upper limit (UL) for bloodroot, as it is not recognized as an essential nutrient. Due to significant safety concerns, most health authorities do not recommend internal use of bloodroot supplements.

When bloodroot extract (sanguinarine) was used in commercial oral care products, concentrations typically ranged from 0.075% to 0.1%. However, even these low concentrations have raised safety concerns, and most manufacturers have discontinued its use.

Anyone considering bloodroot for any purpose should consult with a healthcare provider first, as the risks often outweigh potential benefits.

Food sources

Bloodroot is not consumed as a food and does not naturally occur in the food supply. The plant grows wild in deciduous forests of eastern North America, from Nova Scotia to Florida and west to Manitoba and Kansas. It typically blooms in early spring before trees leaf out.

The rhizome (root) is the part of the plant used medicinally, but it should not be considered a food source due to its toxic alkaloid content. Foraging for bloodroot is not recommended due to identification challenges and safety risks.

Safety & side effects

Bloodroot carries significant safety concerns and potential for serious adverse effects. The FDA has classified bloodroot as unsafe for internal use. Common side effects and risks include:

Topical use: Severe skin irritation, burns, scarring, and tissue destruction. Even small amounts can cause painful, slow-healing wounds.

Internal use: Nausea, vomiting, drowsiness, visual disturbances, and respiratory depression. Large doses can be potentially fatal.

Oral use: Mouth irritation, tongue sensitivity, and potential damage to oral tissues with prolonged use.

The narrow margin between potentially therapeutic and toxic doses makes bloodroot particularly dangerous for self-medication.

Interactions

Limited research exists on specific drug interactions with bloodroot, but several concerns warrant attention:

Medications metabolized by the liver: Bloodroot alkaloids may affect liver enzyme activity, potentially altering the metabolism of other drugs.

Blood-thinning medications: Some alkaloids in bloodroot may affect blood clotting, potentially increasing bleeding risk when combined with anticoagulants or antiplatelet drugs.

Central nervous system depressants: Bloodroot may enhance the sedative effects of alcohol, benzodiazepines, or other CNS depressants.

Who should be cautious

The following groups should avoid bloodroot entirely:

• Pregnant and breastfeeding women
• Children and adolescents
• Individuals with liver disease
• People with respiratory conditions
• Those with a history of glaucoma
• Individuals taking blood-thinning medications
• Anyone with sensitive skin or a history of contact dermatitis

Frequently asked questions

Is bloodroot legal to purchase as a supplement?

While bloodroot supplements may be available, the FDA has issued warnings about products containing bloodroot, particularly those marketed for skin conditions. Many reputable supplement manufacturers have discontinued bloodroot products due to safety concerns.

Can bloodroot cure cancer?

No. There is no scientific evidence that bloodroot can cure cancer. Claims about bloodroot as a cancer treatment are not supported by clinical research and may delay proper medical treatment. Such use is potentially dangerous and should be avoided.

Is bloodroot safe for oral care?

While some studies have shown antimicrobial effects, most oral care manufacturers have removed bloodroot from their products due to safety concerns. Safer alternatives are available for maintaining oral health.

What should I do if I’ve been exposed to bloodroot?

If you’ve applied bloodroot topically and experience burning, irritation, or tissue damage, seek medical attention immediately. For accidental ingestion, contact poison control or emergency services, especially if symptoms like nausea, vomiting, or breathing difficulties occur.

Are there safer alternatives to bloodroot?

Yes. For oral health, proven safe options include fluoride toothpastes, chlorhexidine mouthwashes, and regular dental hygiene. For antimicrobial needs, numerous safer alternatives exist depending on the specific application.
