Catnip

Nepeta cataria

As well as sending your cat into euphoric rapture, catnip also has human-calming properties, and has traditionally been drunk as a warming tea to induce a sweat to shake off seasonal colds.

The frenzy that cats go into when they rub themselves in catnip has recently been discovered to be due to the phytochemical iridoid nepatalactol. It raises feel-good endorphin levels, encouraging the rubbing of it over the head and face, also helping to deter mosquitoes. Its a good example of how animals use secondary plant metabolites as a pest defence as well as how they interact with pain-relieving opioid pathways.

Once you have successfully germinated the seed (which can be slightly erratic), catnip is an easy plant to look after. It prefers full sunshine and well-drained soils. It tolerates drought much better than over-watering, and appears to be resistant to the nibbling of deer or rabbits. Its greatest threat is indeed the carnage caused by delirious pleasure-seeking cats.

Sowing and Growing

Catnip is a low-maintenance, easy plant to grow. Sow indoors anytime from early spring, or directly outdoors once the soil has warmed up a bit. Scatter seeds on the surface and press into the soil; don’t cover with soil as the seed requires light to germinate. Germination can be erratic, especially in cooler temperatures, so be patient and keep the tray / pots moist to allow seeds to keep germinating over a period of several weeks. Scarification is said to improve the germination rate, but we have always had decent results without.

Catnip prefers full sun and well-draining soils. It does not like waterlogged soils and will die off if overwatered. When in full flower the plants reach around 2-3 feet and become quite bushy, so allow a spacing of around 2 feet. It is a fast grower and will normally flower by mid-July in its first year.

Uses and Benefits

Catnip is like a gentle thyme or oregano. It contains some of the powerful thymol and carvacrol but at lower levels. This gentle nature has led it to being included in many recipes for children’s health. Especially tummy upsets with loose bowels. This calming effect is also seen in its use for fraught nerves and anxiety too. Its warming and diaphoretic properties come to the fore when drunk as a warm tea to induce a mild sweat during seasonal colds too.

Harvesting and Preparation

The first flush of leaf growth is the lushest and best for harvest before the flower spikes appear. You can also harvest the stalks as it comes into flower later in the summer too, so leave some of your catnip patch for that as well. Tie the stems up in bunches and leave to air dry or lay out on drying racks and place in a dryer.

For a simple cup of tea use a fresh sprig or a teaspoon of the dried herb in a cup of freshly boiled water and leave covered to infuse for 15 minutes.

Or you can make a 1:5@45% tincture.
