About Licorice Root Tea
Licorice root tea (Gan Cao Cha) is made from the roots and rhizomes of Glycyrrhiza glabra or Glycyrrhiza uralensis. In Traditional Chinese Medicine, licorice is considered one of the most important herbs and appears in more formulations than any other herb. Known as "the peacemaker," it helps harmonize the effects of other herbs and mitigate their harsh properties. Licorice has a naturally sweet taste due to glycyrrhizin, which is about 50 times sweeter than sugar. It is classified as sweet in flavor with a neutral to warm nature, and is said to tonify Spleen Qi, moisten the lungs, clear heat, and detoxify.
Historical Use
Licorice root has been used in Chinese medicine for over 3,000 years and was mentioned in the Shennong Ben Cao Jing, one of the earliest Chinese herbal texts. It was so valued that it earned the title "The King of Herbs" and was often included in imperial tribute offerings. Emperor Shennong classified it as one of the superior herbs that could be taken regularly to promote longevity without toxic side effects when used appropriately.
How to Prepare Licorice Root Tea
Ingredients:
- 3-6g dried licorice root slices or 1-2g licorice powder
- Optional: 1-2 slices of fresh ginger for warming properties
- Optional: 1 dried jujube (red date) for enhanced effects
- 300ml water
Preparation Method:
- If using licorice root slices, briefly rinse under cold water.
- Place the licorice (and any additional herbs) in a ceramic or glass pot.
- Add cold water to the pot and let the herbs soak for about 5 minutes.
- Bring the water to a boil, then reduce to a simmer.
- Simmer gently for 10-15 minutes with the lid slightly ajar.
- Turn off the heat and allow to steep for an additional 5 minutes.
- Strain the liquid into a cup.
- Licorice has a natural sweetness, so additional sweeteners are usually unnecessary.
Recommended Dosage:
Due to potential side effects with prolonged use, limit consumption to 1 cup daily for no more than 4-6 weeks continuously. For acute conditions, may use up to twice daily for shorter periods (1-2 weeks).
Precautions
- Not recommended for people with high blood pressure, heart disease, kidney disease, or liver conditions.
- Avoid during pregnancy as it may increase the risk of premature birth.
- Can cause potassium depletion and sodium retention with prolonged use or high doses.
- May interact with certain medications, including diuretics, corticosteroids, and cardiac glycosides.
- Those with hormone-sensitive conditions should use with caution as licorice has estrogen-like effects.
Modern Research
Scientific studies have identified numerous bioactive compounds in licorice, including glycyrrhizin, flavonoids, and chalcones. Research supports its use for digestive disorders, showing potential benefits for peptic ulcers and acid reflux. Studies also indicate anti-inflammatory, antimicrobial, and antiviral properties, with particular efficacy against certain respiratory conditions. Its compounds have demonstrated hepatoprotective effects and potential benefits for adrenal insufficiency.
