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
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 wind and act as a digestive aid.3
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.
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.
