Catnip is one of our traditional cold and flu remedies. It is a powerful diaphoretic used in any feverish condition, especially in bronchitis. As a carminative with anti-spasmodic properties, Catnip eases any stomach upset, dyspepsia, flatulence and colic. It is a perfect remedy for the treatment of diarrhoea in children. Its sedative action on the nerves adds to its generally relaxing properties. The New Holistic Herbal by David Hoffmann Pg. 189
