Wash and peel a fresh ginger root. Using a small blade grater, grate approximately 1 tbsp. worth of ginger.
Bring a kettle of water to boil. Pour 8 oz. of boiling water in a heat-proof measuring cup. Add the grated ginger and stir. Let the ginger steep for about 10 minutes.
Strain the liquid through a small mesh strainer positioned above a teacup. Discard the ginger pieces and reheat in the microwave if necessary. Use either honey or sugar to sweeten the tea.
Bring a tea kettle full of at least 3 cups water to boil. Once boiled, pour 2 cups into a heat-proof measuring cup.
Add 1 tbsp. chopped lemongrass or 1 tsp. dried lemongrass, 1 tbsp. freshly grated ginger or 1/8 tsp. ground ginger, plus 1 tsp. chamomile flowers or a chamomile teabag. Allow the concoction to steep for at least 15 minutes.
Strain tonic through a mesh strainer positioned over a bowl. Take 1/2 cup of tonic per day to help relieve nausea. To dilute the solution for taste, mix 1/2 cup tonic plus 1/4 to 1/2 cup warm water.
Fill half of a cocktail glass or tumbler with ice.
Measure one part gin and three parts ginger ale. For a 1 cup cocktail, measure 1/4 cup gin and 3/4 cup ginger ale.
Pour the gin over the ice, followed by the ginger ale, then add a lemon or lime wedge. Do not mix in a shaker, as the carbonation will cause pressure to build, and the drink will fizz out of the cup.
