I have been making my own herbal tinctures for over 20 years. I share these topics as starting points for your own research.

These guides offer ideas for your own research, not a recommendation to use a product or change medical treatment. Paul's coaching focuses on life and spiritual guidance.

About Paul and his work

Evidence and safety to consider

Reframed Licorice Root as a traditional herb with limited clinical evidence, removed unverified first-person and product-endorsement language, and added clear glycyrrhizin, interaction, pregnancy, and medical-care safeguards.

Licorice root can contain glycyrrhizin. Large amounts or long-term use can cause serious effects including high blood pressure, low potassium, fluid retention, and heart-rhythm problems. A systematic review found that chronic glycyrrhizic-acid exposure was associated with higher blood pressure and lower potassium. Avoid self-treatment. Ask a pharmacist or clinician before use if you take any medicine, especially diuretics, cardiac glycosides, corticosteroids, stimulant laxatives, blood-pressure medicines, or medicines affected by CYP3A4; or if you have high blood pressure, heart, kidney, or liver disease, low potassium, are pregnant or breastfeeding, or are considering use for a person under 18. Seek medical care for health concerns rather than relying on this information.

Dear soul, the sweetness and earthy character of Licorice Root can invite a quiet, reflective pause. That meaning is personal and traditional, not a proven health effect. This page offers a warm introduction to the herb while keeping its evidence limits, safety considerations, and the role of qualified medical care in clear view.

What It Is

Licorice root is the dried root of Glycyrrhiza glabra, Glycyrrhiza uralensis, or Glycyrrhiza inflata, herbs used as flavorings and in several traditional practices. The National Center for Complementary and Integrative Health (NCCIH) notes that many products called “licorice” do not contain actual licorice root. Its sweetness can be enjoyed as a sensory and cultural detail, while claims about nurturing the body or spirit remain personal or traditional interpretations rather than established medical effects.

Traditional Use and Evidence Limits

Licorice root has a long history of traditional use. The European Medicines Agency (EMA) monograph describes specified preparations as traditional herbal medicinal products for digestive symptoms and as an expectorant in cough associated with a cold. Those indications are based exclusively on long-standing use. They do not establish that a tea, capsule, or other product can diagnose, prevent, or treat a health condition.

Research has not established broad physical or emotional benefits from licorice root. NCCIH says there is not enough high-quality evidence to clearly support its use for any health condition, and it is unclear whether products containing licorice alone affect digestive symptoms. A tea ritual may still feel comforting as a personal practice, but words such as “protection,” “balance,” and “healing” are reflective metaphors here, not treatment claims.

Product Formats and Safety

Licorice root is sold in foods, teas, loose-herb products, capsules, and extracts. This page does not provide a preparation method, dose, or self-treatment plan because product composition and glycyrrhizin exposure vary and can matter for safety. A pharmacist or clinician can help review a specific product in the context of your medicines and health history.

  • Licorice contains glycyrrhizin, which can cause serious effects including irregular heartbeat and cardiac arrest, especially with large amounts or long-term use. Risk can be greater for people with high blood pressure or heart or kidney conditions.
  • The EMA advises against combining liquorice root preparations with diuretics, cardiac glycosides, corticosteroids, stimulant laxatives, or medicines that can worsen electrolyte imbalance. It may also affect some medicines metabolized by CYP3A4.
  • Do not rely on a personal “start small” approach to manage risk. Discuss licorice with a pharmacist or clinician before use if you take medicines, have high blood pressure, heart, kidney, or liver disease, have low potassium, are pregnant or breastfeeding, or are considering it for someone under 18.

Rather than recommend named products, this page keeps the focus on evidence and safety. A tea, capsule, or loose herb is not a treatment recommendation, and an online listing alone cannot show whether a product is appropriate for a particular person.

  • Tea products may contain licorice root and other ingredients. Their flavor or ritual value does not establish a health benefit.
  • Capsules and extracts can differ substantially from teas and from each other. “Natural” does not mean they are free of interactions.
  • Loose-root products still require the same safety conversation, especially when glycyrrhizin exposure or concurrent medicines are relevant.

If a plant-centered ritual feels meaningful, it can be held as a reflective part of your personal or spiritual life. It should not replace evaluation of symptoms, prescribed treatment, or advice from the clinician who knows your care.

May you make room for patience and personal reflection, while making safety and informed health decisions part of the journey too.

Questions to guide your research

What is Licorice Root?

Licorice root is the root of Glycyrrhiza glabra, G. uralensis, or G. inflata. It is used as a flavoring and in traditional herbal practices. Many products described as licorice-flavored do not contain actual licorice root.

What does research say about Licorice Root?

Licorice root has a history of traditional use for specified digestive symptoms and cough associated with a cold, but NCCIH says there is not enough high-quality evidence to clearly support its use for any health condition. Traditional use is not proof that a product will treat a condition.

What safety issues should I know about Licorice Root?

Glycyrrhizin in licorice can raise blood pressure, lower potassium, and contribute to serious heart-rhythm problems. Medicines and conditions can increase risk, so discuss a specific product with a pharmacist or clinician before use rather than relying on general online advice.
