Good morning detox drink

A drink that keeps the cold away 
Source: My mom told me it's good for you

Taste: 1 (out of 5) - you're drinking it for health benefits
Difficulty: 1 (out of 5)

Source:
- 1/2 gallon / 2 liters water
- 3 inches fresh ginger ground, or 3 frozen ginger cubes
- 1 lemon or lime cut in half
Total: 16 servings of 1/2 cup

Directions:
1. Add all ingredients to a large pot, bring to boil, remove from heat and allow to cool. Pour into clean jars and refrigerate.
2. Warm up (e.g. in a microwave) 1/2 cup and drink first thing in the morning before eating anything else.

Afterthoughts:
I really don't like the taste, but I believe this drink is great for preventing colds, and generally strengthening the immune system and cleansing the body. I tried something similar with horseradish several years back, and it kept me healthy all winter. As much as I don't like this ginger drink it tastes much better than the horseradish. I'll wait and see if it's as effective.
