Best Practices for Brewing Herbal Teas
Before diving into the specific herbs, it’s essential to understand the best practices for brewing herbal teas. To extract the maximum benefits from these herbs:
- Use Fresh or Properly Dried Herbs: Fresh herbs provide potent flavors, but dried herbs are more convenient and have a longer shelf life.
- Use Pure Water: Filtered or spring water ensures no contaminants interfere with the herbs’ properties.
- Optimal Water Temperature: Most herbal teas should be brewed with water just below boiling (around 200°F or 93°C).
- Steep Time: Steeping for 5-10 minutes is ideal, although tougher herbs (like roots) might require up to 15 minutes.
- Covered Brewing: Covering your cup while brewing traps steam, helping to preserve volatile oils and beneficial compounds.
Now, let’s explore the top 19 immune-boosting herbs, their unique properties, and how best to use and store them.
