Therapeutics:

Many folks are surprised to hear of catnip being used as a medicinal herb. Catnip really isn’t just for cats, it’s for people too! In fact, catnip has the polar opposite effect on humans as it does to our feline friends. While the herb makes cats feisty and frisky, in humans it is a gentle but powerful nervous system relaxant and sedative.

Catnip is one of the classic herbs for a children’s apothecary. It’s typically thought of as the ideal fever remedy for young children, employed either as a bath or tea to promote sweating and open the pores of the skin to release fever. The other aspect that must be considered in caring for feverish children is the nervous system component. Illness can be very distressing for children so turning to herbs which help to relax the child will be supportive to their recovery.

Matthew Wood writes about catnip as being indicated for people who hold tension in their belly and internalize stress to the stomach. This can look like anxiety associated with GI symptoms and a tightening sensation in the gut when presented with a stressful circumstance. Often people who store stress this way end up developing chronic conditions related to the gastrointestinal tract- such as IBS. I write about this as one of those people, the gut is one of my major holding places. Upon taking catnip, I find it creates a diffusive sensation in my core which radiates the tension out to be released. 

As a carminative herb catnip brings warmth to the gut, promoting healthy digestion and easing symptoms of gas and bloating. The antispasmodic qualities are particularly helpful here as well, quite literally relaxing the muscles around the gut to release tension. Using herbs internally is not recommended until an infant is around 6 months old and the lining of the gastrointestinal tract seals. However, catnip may be used as a bath for infants with gas pain.

Catnip is a wonderful herb for helping to fall asleep and improving the overall quality of sleep. In older babies and toddlers, catnip is supportive for teething pain that is disruptive to sleep and leaves the child feeling restless and agitated. Throughout childhood, it can be thought of for circumstances that leave them feeling withdrawn and on edge.
