Overview

Overview Information

Goldenseal is an herb. The dried root is used to make medicine.

Goldenseal is used for many conditions, but so far, there isn’t enough scientific evidence to determine whether or not it is effective for any of them.

We do know that goldenseal isn’t effective for its most famous use, masking illegal drugs in the urine. Despite rumors to the contrary, goldenseal won’t cause false-negative results for marijuana, cocaine, amphetamines or numerous other illegal drugs. Interestingly, the idea of using goldenseal to alter drug screen results came from the novel Stringtown on the Pike, by the pharmacist John Uri Lloyd. However, in this book, goldenseal caused a false-positive for strychnine poisoning, not illegal drugs.

Goldenseal is also used for the common cold and other upper respiratory tract infections, as well as stuffy nose and hay fever. Some people use goldenseal for digestive disorders including stomach pain and swelling (gastritis), peptic ulcers, colitis, diarrhea, constipation, hemorrhoids, and intestinal gas.

Goldenseal is used for urinary tract infections (UTIs), internal bleeding, bleeding after childbirth, liver disorders, cancer, chronic fatigue syndrome (CFS), jaundice, gonorrhea, fever, pneumonia, malaria, whooping cough, and an eating disorder called anorexia.

Women use goldenseal for vaginal pain and swelling and menstrual period problems.

Goldenseal is applied to the skin for rashes, ulcers, wound infections, itching, eczema, acne, dandruff, ringworm, herpes blisters, and cold sores. It is used as a mouthwash for sore gums and mouth.

Some people use goldenseal as an eyewash for eye inflammation and eye infections called conjunctivitis, or “pink eye.”

Goldenseal is used in the ears for ringing, earache, and deafness.

Goldenseal is commonly found in the deep woods from Vermont to Arkansas and received its name from the golden-yellow scars on the base of the stem. When the stem is broken, the scar resembles a gold wax letter seal.

How does it work?

Goldenseal contains the chemical berberine, which might have effects against bacteria and fungi. For example, it can prevent the bacteria Escherichia coli (E. coli) from binding to urinary tract walls. Berberine also has properties that can lower blood pressure and improve irregular heartbeats. In addition, early research suggests that berberine can lower blood sugar and “bad” low-density lipoprotein (LDL) cholesterol.

Many of the important chemicals in goldenseal are poorly absorbed when taken by mouth and might not reach the concentrations needed to have significant effects in humans. So, it is unknown whether goldenseal has the same benefits as berberine.

Uses

Uses & Effectiveness?

Possibly Ineffective for

  • Masking illegal drugs in urine tests. Goldenseal is often promoted to mask illicit drugs in the urine, but taking goldenseal by mouth does not seem to cause a false-negative result on drug tests for amphetamines, barbiturates, benzodiazepines, cocaine, opiates, phencyclidine, and tetrahydrocannabinol (THC). Drinking one gallon of water with goldenseal does not increase the number of false negatives over water alone.

Insufficient Evidence for

  • Urinary tract infections (UTIs).
  • Hemorrhoids.
  • Stomach upset.
  • Loss of appetite (anorexia).
  • Stomach ulcers.
  • Colitis.
  • Menstrual irregularities.
  • Chronic fatigue syndrome (CFS).
  • Conjunctivitis.
  • Nasal congestion.
  • Hay fever.
  • Other conditions.
More evidence is needed to rate goldenseal for these uses.

Side Effects

Side Effects & Safety

Goldenseal is POSSIBLY SAFE for most adults when taken by mouth as a single dose. There is not enough reliable information to know if goldenseal is safe for long-term use.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Using goldenseal during pregnancy or breast-feeding is LIKELY UNSAFE for the infant. A hazardous chemical in goldenseal can cross the placenta and can also find its way into breast milk. Brain damage (kernicterus) has developed in newborn infants exposed to goldenseal. Do not use goldenseal during pregnancy or breast-feeding.

Children: Don't use goldenseal in newborn babies. It is LIKELY UNSAFE for them. It might cause brain damage (kernicterus).

Interactions

Interactions?

Moderate Interaction

Be cautious with this combination

!
  • Cyclosporine (Neoral, Sandimmune) interacts with GOLDENSEAL

    The body breaks down cyclosporine (Neoral, Sandimmune) to get rid of it. Goldenseal might decrease how fast the body breaks down cyclosporine (Neoral, Sandimmune). This might cause there to be too much cyclosporine (Neoral, Sandimmune) in the body and potentially cause side effects.

  • Digoxin (Lanoxin) interacts with GOLDENSEAL

    Taking goldenseal with digoxin (Lanoxin) might cause a very slight increase in digoxin (Lanoxin) levels in the body. But this does not seem to be an important interaction.

  • Medications changed by the liver (Cytochrome P450 2D6 (CYP2D6) substrates) interacts with GOLDENSEAL

    Some medications are changed and broken down by the liver. Goldenseal might decrease how quickly the liver breaks down some medications. Taking goldenseal along with some medications that are changed by the liver can increase the effects and side effects of your medication. Before taking goldenseal talk to your healthcare provider if you take any medications that are changed by the liver.<br /><br /> Some medications that are changed by the liver include amitriptyline (Elavil), clozapine (Clozaril), codeine, desipramine (Norpramin), donepezil (Aricept), fentanyl (Duragesic), flecainide (Tambocor), fluoxetine (Prozac), meperidine (Demerol), methadone (Dolophine), metoprolol (Lopressor, Toprol XL), olanzapine (Zyprexa), ondansetron (Zofran), tramadol (Ultram), trazodone (Desyrel), and others.

  • Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates) interacts with GOLDENSEAL

    Some medications are changed and broken down by the liver.<br /><br /> Goldenseal might decrease how quickly the liver breaks down some medications. Taking goldenseal along with some medications that are broken down by the liver can increase the effects and side effects of some medications. Before taking goldenseal, talk to your healthcare provider if you are taking any medications that are changed by the liver.<br /><br /> Some medications changed by the liver include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and many others.

  • Medications moved by pumps in cells (P-Glycoprotein Substrates) interacts with GOLDENSEAL

    Some medications are moved by pumps in cells. Goldenseal might make these pumps less active and increase how much of some medications get absorbed by the body. This might increase the amount of some medications in the body, which could lead to more side effects. But there is not enough information to know if this is a big concern.<br /><br /> Some medications that are moved by these pumps include etoposide, paclitaxel, vinblastine, vincristine, vindesine, ketoconazole, itraconazole, amprenavir, indinavir, nelfinavir, saquinavir, cimetidine, ranitidine, diltiazem, verapamil, corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.

Dosing

Dosing

The appropriate dose of goldenseal depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for goldenseal. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
