Bad breath. For bad breath put a couple of teaspoons of salt in a cup (about half) full of boiling water. Dissolve the salt. Add some cold water to regulate the temperature. Gargle.
Urinary tract infections. For urinary tract infections try kawakawa as a cup of tea. Get a couple of leaves that are exposed to the east sunlight. Pick the leaves that have been eaten by bugs (plenty of wholes in the them). These are the leaves that have the highest potency and greatest medicinal qualities. Give the leaves a quick wash. Place two leaves in the bottom of a cup and add boiling water. Let the leaves percolate and let the cup sit until the water is a suitable temperature to drink. Drink hot like a cup of tea.
