Interaction Details

Niacin (prescription drug) is classified as belonging to the following category: Hepatotoxic Drugs

Theoretically, high doses of spearmint might increase the risk of liver damage when taken with hepatotoxic drugs.
Animal research suggests that drinking spearmint tea for 30 days can increase markers of liver damage, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and cause liver degeneration and necrosis, in a dose-dependent manner. This effect has not been reported in humans.

Interaction Rating

Spearmint Overview

Spearmint Spearmint (Mentha spicata) is a perennial herb in the mint family (Lamiaceae) and is native to Europe and Asia. It is known for its minty aroma and flavor and is commonly used in cosmetics, cooking, and herbal remedies. Spearmint has been used traditionally in herbal medicine to treat a number of conditions, including digestive problems, nausea, and skin conditions. It is purported to have a number of potential health benefits, including reducing inflammation, improving digestion, and relieving stress and anxiety. When used as a dietary supplement, spearmint is often standardized based on the rosmarinic acid content.

Niacin (prescription drug) Overview

  • Niacin is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol (a fat-like substance) and other fatty substances in your blood and to increase the amount of high density lipoprotein (HDL; ''good cholesterol''). Niacin can be used in a number of situations including the following:

    • alone or in combination with other medications, such as HMG-CoA inhibitors (statins) or bile acid-binding resins;

    • to decrease the risk of another heart attack in patients with high cholesterol who have had a heart attack;

    • to prevent worsening of atherosclerosis (buildup of cholesterol and fats along the walls of the blood vessels) in patients with high cholesterol and coronary artery disease;

    • to reduce the amount of triglycerides (other fatty substances) in the blood in patients with very high triglycerides who are at risk of pancreatic disease (conditions affecting the pancreas, a gland that produces fluid to break down food and hormones to control blood sugar).

  • Niacin is also used to prevent and treat pellagra (niacin deficiency), a disease caused by inadequate diet and other medical problems. Niacin is a B-complex vitamin. At therapeutic doses, niacin is a cholesterol-lowering medication.

  • Results of a clinical study in people with heart disease and well-controlled cholesterol levels that compared people who took niacin and simvastatin with people who took simvastatin alone and found similar results for the two groups in the rate of heart attacks or strokes. Taking niacin along with simvastatin or lovastatin also has not been shown to reduce the risk of heart disease or death compared with the use of niacin, simvastatin, or lovastatin alone. Talk to your doctor if you have questions about the risks and benefits of treating increased amounts of cholesterol in your blood with niacin and other medications.
