Rating	Health Concerns
	Cough Insomnia
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit.

Traditional Use

Historical or traditional use (may or may not be supported by scientific studies)

Catnip is famous for inducing a delirious, stimulated state in felines. Throughout history, this herb has been used in humans to produce a sedative effect.¹ Several other conditions (including cancer, toothache, corns, and hives) have been treated with catnip by traditional herbalists.

Active Constituents

Active constituents

The volatile oil in catnip contains the monoterpene, nepetalactone, which is similar to the valepotriates found in valerian, a more commonly used herbal sedative.² Human trials are lacking to prove the effectiveness of catnip for treating insomnia. It has been used traditionally to reduce gas and act as a digestive aid.³

Dosage

How much is usually taken?

A catnip tea can be made by adding 1 cup (250 ml) of boiling water to 1-2 teaspoons (5-10 grams) of the herb; cover, then steep for ten to fifteen minutes. Drink 2-3 cups per day.⁴ For children with coughs, 1 teaspoon (5 ml) of tincture three times per day can be used. Adults may take twice this amount.

Side Effects

Are there any side effects or interactions?

No common side effects have been associated with the use of catnip. Since catnip (particularly the volatile oil) may act to promote uterine contractions, it should not be used during pregnancy.

At the time of writing, there were no well-known drug interactions with catnip.
