This article explains the medicinal, horticultural, botanical, and historical aspects of Sanguinaria canadensis.

What are the medicinal properties of Sanguinaria canadensis?

Sanguinaria canadensis helps with cancer treatment, pain relief, and skin conditions such as eczema and acne. Its alkaloids and glycosides exhibit anti-inflammatory and antimicrobial properties. Traditional medicine has used bloodroot for centuries to treat various ailments.

The active constituents of bloodroot include sanguinarine, chelerythrine, and protopine. These alkaloids are responsible for its medicinal properties. Sanguinarine is particularly effective against cancer cells and has been shown to inhibit the growth of tumors. Chelerythrine has antibacterial and anti-inflammatory effects.

The parts of the bloodroot plant most used for medicinal purposes are the root and rhizome. The root contains the highest concentration of sanguinarine and chelerythrine, making it the most effective part for medicinal use. The root is typically harvested in the spring and dried for later use.

Improper use of bloodroot can lead to side effects such as skin irritation, gastrointestinal upset, and respiratory problems. Sanguinarine can also cause allergic reactions, including anaphylaxis, in rare cases. Pregnant and breastfeeding women should avoid using bloodroot due to its potential risks.

When using bloodroot medicinally, it is essential to follow proper dosages and preparation methods. The dried root should be taken in small amounts, ideally 10-20 milligrams, to avoid toxicity. Bloodroot should not be taken orally for extended periods, and caution should be exercised when using it in conjunction with other medications.

What are the horticulural aspects of Sanguinaria canadensis?

Sanguinaria canadensis grow in USDA Hardiness Zones 3-9, requiring partial shade and well-drained, moist soil with a pH between 5.5 and 7.0. Soil must be rich in humus and have adequate organic matter. Full sun can cause leaf scorch.

Plant Sanguinaria canadensis in the fall, 12-18 inches apart, to allow for optimal root establishment before winter dormancy. Spring plantings can be done in early May, but may require supplemental watering. Divide plants every 3-4 years to maintain vigor.

Harvest Sanguinaria canadensis roots in the fall, after leaves have turned yellow and fallen, to minimize leaf damage. Dig carefully to avoid breaking roots. Clean and dry roots promptly to prevent fungal growth. Roots can be harvested every 3-4 years.

Common pests of Sanguinaria canadensis include slugs, snails, and Japanese beetles. Fungal diseases such as root rot, leaf spot, and crown rot can also affect the plant, often caused by overwatering or poor soil drainage. Regular monitoring and pruning can help prevent infestation and disease.
