Licorice Root: The Sweet Healer Across Cultures and Centuries

 



Introduction

    Licorice root (Glycyrrhiza glabra) is far more than a candy flavoring—it’s one of the most historically celebrated and therapeutically valuable herbs in herbal medicine. Used for over 4,000 years across diverse cultures, it has been treasured for its sweet taste and remarkable healing properties. Whether steeped in tea, extracted into tinctures, or incorporated into traditional formulas, licorice root continues to serve as a bridge between ancient traditions and modern herbalism.

A Legacy from Antiquity

    The name "licorice" is derived from the Greek words glukos (sweet) and riza (root), literally meaning “sweet root.” This name only begins to hint at the herb’s broader legacy.

    Licorice root was a favorite in Ancient Egypt, often included in pharaohs’ tombs as a treasured afterlife companion. Archaeologists discovered licorice root in the tomb of King Tutankhamun, where it was believed to offer vitality in the next world. Egyptian healers brewed it into a drink known as mai sus, consumed to soothe the stomach and throat.

    In Traditional Chinese Medicine (TCM), licorice root is known as gan cao and is called “The Great Harmonizer.” It’s a component of more than half of all herbal formulas in Chinese practice. TCM practitioners use it to tonify the Qi (vital energy), moisten the lungs, ease spasms, and detoxify other herbs within complex formulas.

    In Ayurveda, India’s ancient healing system, licorice is called mulethi and is valued for rejuvenating the digestive system, calming the throat, and promoting strength in the respiratory system. It is also used as an adaptogen—helping the body manage stress and balance hormonal systems.

Therapeutic Benefits of Licorice Root

    Modern research has confirmed many of the traditional benefits associated with licorice. Here are some of the most validated and widely-used applications today:

1. Digestive Support

    Licorice root soothes gastrointestinal inflammation, promotes healing of the stomach lining, and is often used in treating ulcers and acid reflux. A special form called deglycyrrhizinated licorice (DGL) is used to avoid raising blood pressure while still supporting the digestive tract.

2. Respiratory Relief

    Licorice acts as a natural demulcent and expectorant, helping loosen mucus, relieve throat irritation, and calm coughing. It’s commonly added to cough syrups and lung teas for this reason.

3. Adrenal and Stress Support

    As an adaptogenic herb, licorice root supports the adrenal glands, helping to balance cortisol levels during periods of chronic stress and fatigue. This makes it useful in formulas for burnout, low energy, and immune weakness due to stress.

4. Anti-Inflammatory & Antiviral Actions

    Licorice contains compounds such as glycyrrhizin, which possess potent anti-inflammatory and antiviral effects. It’s been used to help manage infections like hepatitis, herpes, and even certain respiratory viruses.

Cautions and Contraindications

    Although licorice is a powerful healer, it is not for everyone. Long-term or high-dose use—especially of products containing glycyrrhizin—can lead to elevated blood pressure, water retention, and potassium imbalance. This makes it contraindicated for people with hypertension, kidney disorders, or heart disease unless under professional guidance.

    Using DGL (deglycyrrhizinated licorice) is a safer alternative for those who want the digestive benefits without the blood pressure risk.

Traditional and Modern Preparations

Licorice root can be used in a variety of forms depending on the desired use:

  • Tea/Infusion: Best for soothing sore throats, coughs, and digestive upset.

  • Tincture/Extract: Used for adrenal support, antiviral action, and long-term formulations.

  • Powder: Can be added to capsules or used topically for skin healing.

  • DGL Lozenges: Great for ulcers, acid reflux, and mouth irritation.
