Most cat owners will grow common catnip as a treat for their feline buddies, but as a member of the mint family, humans may find uses for it as well. Catnip has long been used for medicinal purposes, and a tea made from the dried leaves purportedly relieves digestive upsets, coughs, and even helps reduce stress. The three-foot tall plant is allegedly a natural bug repellent as well, deterring mosquitoes and coackroaches. Catnip tends to self-sow and thus may become a nuisance. The easiest way to prevent that, aside from planting it in pots, is to pinch off flowers or trim back the entire shrub when blooms appear. This will keep the shrub compact, with enough time for it to grow back before harvesting in the fall.
