1. What is Herbal Tea?

An herbal tea is a beverage prepared from plants (other than the tea plant) steeped in hot or boiling water.

🌿 Official Definition

The term tisane comes from the Greek ptisanê (hulled barley). Today, it refers to any drink obtained by aqueous extraction of plant material (leaves, flowers, roots, bark, fruits) other than tea. Herbal tea is naturally caffeine-free.

🚫 Caffeine-Free

No theine, ideal for evenings and children.

💊 Therapeutic Virtues

Each plant has its medicinal properties.

💧 Hydration

Healthy alternative to sugary drinks.

🌱 100% Natural

Pure plants, no additives or preservatives.

💡 Tisane vs Infusion

In common language, tisane and infusion are synonymous. Technically, infusion is a preparation method (pouring hot water), while tisane refers to the caffeine-free plant-based drink. See our complete guide to infusions.

2. Types of Preparation

Three methods exist for preparing herbal tea:

☕ Infusion (most common)

Method: Pour hot water (90-100°C) over the plants and let steep.

  • For: Leaves, flowers, tender parts
  • Duration: 5-10 minutes
  • Advantage: Preserves fragile active ingredients

Example: Chamomile, mint, verbena, linden.

🔥 Decoction

Method: Boil the plants in water for several minutes.

  • For: Roots, barks, seeds, hard parts
  • Duration: 10-20 minutes of boiling
  • Advantage: Maximum extraction of active ingredients

Example: Ginger, licorice, burdock, cinnamon.

❄️ Maceration (cold)

Method: Soak the plants in cold water for several hours.

  • For: Plants with heat-sensitive active ingredients
  • Duration: 4-12 hours
  • Advantage: Preserves thermosensitive compounds

Example: Marshmallow, mallow (mucilages).

Method Plant parts Temperature Duration
Infusion Leaves, flowers 90-100°C 5-10 min
Decoction Roots, barks 100°C (boiling) 10-20 min
Maceration Fragile plants Cold water 4-12 hours

5. How to Prepare a Perfect Herbal Tea

The steps for a successful herbal tea:

📋 The Ideal Protocol
  1. Choose quality plants (organic if possible)
  2. Measure: 1 to 2 teaspoons per cup (250ml)
  3. Heat water to the correct temperature (see table)
  4. Pour water over the plants
  5. Cover to retain essential oils
  6. Wait the recommended infusion time
  7. Filter and enjoy (sweeten with honey if desired)
Plant Dosage/cup Temperature Time
Chamomile 1-2 tsp 90°C 5-10 min
Mint 1-2 tsp 90°C 5-8 min
Verbena 1-2 tsp 90°C 5-10 min
Linden 1 tbsp 95°C 8-10 min
Ginger 3-4 slices 100°C 10-15 min
Hibiscus 1-2 tsp 95°C 5-10 min
💡 Pro Tip: Always Cover!

Place a lid or saucer over your cup during infusion. Essential oils are volatile: without a lid, they evaporate with the steam, and you lose some of the benefits and aromas.

💡 Loose Leaf vs. Tea Bags

Loose leaf plants are generally of better quality (whole leaves, fresher) than industrial tea bags (crushed plants). Invest in a good infuser.

6. Tips and Precautions

Herbal teas have real effects. A few rules:

⚠️ Important Precautions

Some plants are not recommended during pregnancy (sage, strong peppermint, liquorice...), breastfeeding, or when taking medications. If in doubt, consult a healthcare professional or herbalist.

✅ Good Practices
  • Quality: Prioritize organic and traceable plants
  • Freshness: Consume within one year of purchase
  • Storage: Away from light and humidity
  • Dosage: 2-4 cups/day for common plants
  • Variety: Alternate plants, don't always consume the same one
🚫 To Avoid
  • Excess: Even natural, plants have effects
  • Prolonged self-medication: Consult if symptoms persist
  • Unknown plants: Don't pick just anything
  • Tap water: Chlorine alters the aromas
