My cat gets much more excited about catnip than me but after learning more about it I think it’s pretty exciting too. Catnip is an antispasmodic and nervine, making it calming for both your tummy and your nerves. It’s a perennial and a member if the mint family. It can be used as a tea to help gas, stomach cramping and colic. A combination of fennel and catnip makes a wonderful tincture for gas or colic in babies. Catnip is very gentle, making it a great herb to use for children.
