Grate the lotus root and ginger and squeeze out the juice to make the tea.
In a small saucepan, add the juice from lotus root and ginger, add the water and a smidgen of salt (measured by scooping it with tips of two chopsticks), then bring to a boil.
Drink up while it's hot.
When you have a high fever (38℃ or more) and cough, it's best to drink fresh lotus root tea. For that, add 1 teaspoon of the juice from grated ginger and a tiny smidgen of salt (just a few grains scooped onto the tip of a chopstick.)
Use the grated ginger as filling for oyaki rice pancakes or hamburgers.
Story Behind this Recipe
This is a macrobiotic recipe.
The nodes of the lotus root have a stronger medicinal effect. For coughs with lots of phlem, use dried lotus powder.
