Mechanism of Action:
The applicable part of catnip is the flowering tops. The pharmacological effect
that catnip is famous for is the euphoric state it induces in cats. It is thought that
the constituent cis-trans-nepetalcatone produces the characteristic stimulation
in cats only when they smell it (1). Although humans have used catnip to
induce a euphoric high, whether or not this effect actually occurs in humans
is controversial. In humans, the constituent nepetalactone is thought to be
responsible for catnip's calming effects in insomnia, anxiety, gastrointestinal (GI)
conditions, and migraine headache. Nepetalactone is the major component (80-
95%) of the volatile oil of catnip and is structurally related to the valepotriates
found in valerian. Catnip provides approximately 0.2-1% volatile oil. Catnip
reportedly also has antipyretic and diaphoretic effects, which have been
attributed to its use for colds, flu, and fever. Other reported pharmacological
effects, include diuretic and stimulation of gallbladder activity (2).
Report an Adverse Reaction to CATNIP
Catnip abuse may result in headache and malaise. Large amounts of tea may
cause vomiting (2). One case report exists of a nineteen-month-old child who
developed a stomachache and irritability, followed by lethargy and a hypnotic
state after ingesting raisins soaked in catnip tea and chewing on the tea bag (5).

PELVIC INFLAMMATORY DISEASE (PID) and MENORRHAGIA: Because
catnip is also used to stimulate menstruation, theoretically it is contraindicated in
pelvic inflammatory disease (PID) and excessive menstrual bleeding (3).

cause additive CNS depression when combined with anesthesia and other
medications during and after surgical procedures. Tell patients to discontinue
