Goldenseal Root Capsules - Benefits, Uses, Safety & Research

The Health Benefits and Uses of Goldenseal Root Capsules

Goldenseal is a medicinal herb that grows wild in parts of North America. The roots of the goldenseal plant have been used for centuries by Native Americans and early settlers as a natural remedy for various health conditions. Today, goldenseal remains a popular herbal supplement, commonly sold in capsule form. Read on to learn more about the many purported benefits of taking goldenseal root capsules and how to use them safely and effectively.

What is Goldenseal?

Goldenseal, also known by its Latin name Hydrastis canadensis, is a flowering perennial plant native to southeastern Canada and the northeastern United States. It grows well in the shady, rich soil of wooded areas. Goldenseal gets its name from its distinctive yellow-colored roots. Once the plant dies back in winter, the yellow roots are harvested and dried for use in herbal remedies.

Active Compounds in Goldenseal

The therapeutic effects of goldenseal are attributed primarily to two alkaloid compounds found abundantly in the roots:

• Berberine - Has antioxidant, anti-inflammatory, and antimicrobial properties
• Hydrastine - Has antiseptic and astringent effects

These alkaloids are believed to provide goldenseal's medicinal benefits. However, research on their mechanisms of action is limited.

Traditional Medicinal Uses of Goldenseal

Native Americans traditionally used goldenseal for a variety of health purposes including:

• Treating wounds and ulcers
• Relieving digestive issues like diarrhea
• Reducing inflammation and swelling
• Fighting infections

The Cherokee people specifically used goldenseal to treat skin and eye irritations. Frontiersmen and early American settlers learned of goldenseal's healing properties from Native Americans and adopted it into folk medicine.

Modern Uses of Goldenseal

Today goldenseal remains a popular herbal remedy used to:

• Boost immunity
• Fight inflammation
• Treat digestive complaints
• Heal skin issues
• Reduce nasal congestion
• Fight bacterial and viral infections

It is also sometimes used to mask detection of certain drugs in urine tests, although this practice remains controversial.

Goldenseal Root Capsules

Goldenseal root powder is commonly encapsulated and sold in supplement form. Typical dosages range from 250 mg to 500 mg taken 1 to 3 times per day. It may also be prepared as a tea using 1 teaspoon powder per cup of hot water.

Look for goldenseal root capsules standardized to contain 5% berberine, which ensures optimal potency. Combination formulas may also include goldenseal along with complimentary herbs like echinacea or elderberry.

Potential Benefits of Goldenseal Capsules

While substantial clinical research is lacking, goldenseal root capsules may offer certain health benefits:

Immune Support

With its history of use against infections, goldenseal may help strengthen the immune system. Berberine in particular may stimulate immune activity.

Anti-Inflammatory Effects

The alkaloids in goldenseal appear to reduce inflammation, which could help alleviate inflammatory conditions like sinusitis or certain skin conditions.

Improved Digestive Health

Goldenseal has traditional use against gut issues like diarrhea and may help relieve constipation and nausea. Its berberine content may combat bacteria and parasites.

Fights Bacteria and Viruses

Test tube studies indicate goldenseal's antibacterial and antiviral capabilities, which may help fight infections. More research is needed to confirm effects in humans.

Heals Wounds

When applied topically, goldenseal may aid wound healing and soothe skin irritations, as it has traditionally been used by Native Americans and herbalists.

Is Goldenseal Safe?

When taken by mouth in appropriate doses short-term, goldenseal is likely safe for most adults. However, some side effects are possible:

• Digestive upset like nausea or diarrhea
• Increased blood pressure
• Uterine contractions in pregnant women
• Allergic reactions in those sensitive to goldenseal

Goldenseal use should be avoided in:

• Pregnant or breastfeeding women
• Infants and young children
• Those with high blood pressure
• People taking medications it may interact with

Long-term oral use of goldenseal is not recommended, as it may cause side effects. Seek medical advice to ensure appropriate and safe use.

Possible Drug Interactions

Goldenseal may impact the effectiveness and side effects of a number of medications. It is critical to speak to your doctor before using goldenseal if you take any medications, including:

• Anticoagulant or antiplatelet drugs
• Antiarrhythmics
• Antidepressants
• Antidiabetic drugs
• Antihypertensives
• Digoxin
• Sedatives

Choosing a Quality Goldenseal Supplement

When selecting a goldenseal capsule product, choose one that:

• Uses the whole root, not just stem or leaf
• Is standardized to 5% berberines
• Is certified USDA organic
• Is free of harmful additives
• Comes from a trusted manufacturer

Growing Your Own Goldenseal

While wild-harvesting goldenseal may deplete natural populations, it is possible to grow your own goldenseal. Seeds or rhizome cuttings are planted in rich, shaded soil. It takes 3-5 years for plants to mature enough for harvest. Growing goldenseal helps conserve this valuable medicinal plant.

The Bottom Line on Goldenseal Capsules

With a long history of traditional use, goldenseal root capsules may offer benefits for immune support, inflammation, digestion, and fighting infection. However, research is limited on its effectiveness and more studies are needed. When taken short term, goldenseal is likely safe for most people, but may cause side effects or interact with medications. As with any herbal supplement, consult your healthcare provider before use.
