How Much Licorice Root Tea per Day?
1–2 cups (about 240–480 mL) of licorice root tea per day is not an established safe dose; no reliable daily cup range is known. Risk depends on the tea’s glycyrrhizin content, your health conditions and medications, whether you are pregnant, and how long you drink it. Treat licorice root tea as an occasional choice rather than a daily health routine, and ask a clinician before using it regularly.
How much licorice root tea can you drink per day?
There is no evidence-backed number of cups that can be recommended as safe for everyone. A cup is a measure of liquid, not a measure of glycyrrhizin, the natural licorice root compound responsible for some important risks.
Glycyrrhizin can cause the body to retain sodium and water and lose potassium. This can raise blood pressure and, in some circumstances, contribute to an abnormal heart rhythm. People differ in their susceptibility, so an amount tolerated by one person is not necessarily safe for another.
Research on this topic is limited. A case report on licorice-induced low potassium describes harm after long-term consumption of natural licorice root; it was not a controlled trial of licorice root tea and does not establish a safe number of cups.
Several factors make a cup-based limit difficult to calculate:
- Product strength: Licorice root products can contain different amounts of glycyrrhizin, and a package may not state how much ends up in a cup.
- Preparation: The amount of licorice root and how it is brewed can affect the strength of the tea.
- Frequency: Regular use can increase exposure over time. There is no established duration that guarantees safety.
- Other sources: Licorice root in sweets, supplements or herbal blends can add to your total exposure.
A package’s suggested serving is a preparation guide, not proof that the serving is safe for your circumstances. If you want to drink licorice root tea routinely, show the product label to a clinician or pharmacist and discuss your health history and medicines.
Does the amount of licorice root tea depend on your goal?
No goal establishes a safe daily dose. The same uncertainty about glycyrrhizin applies whether you drink licorice root tea for flavor or hope it will provide a health benefit.
| Goal | What to know about the amount |
|---|---|
| Flavor | There is no proven safe daily cup limit; occasional use is a more cautious choice than a daily habit, but it is not risk-free. |
| Hydration | Licorice root tea contributes fluid, but there is no reason to drink it daily to meet hydration needs. |
| Digestive comfort | The evidence listed does not establish an effective or safe daily amount of licorice root tea for digestive symptoms. |
| Throat comfort | A comforting warm drink does not establish a therapeutic dose of licorice root tea. |
| Detox | No daily amount of licorice root tea is known to enhance the body’s detoxification. |
The liver and kidneys do most of the body’s detoxification; the lungs and gut also help eliminate waste, while sweat removes only trace amounts. Persistent digestive or throat symptoms deserve medical advice rather than an increasing amount of licorice root tea.
What are the signs you may be overdoing licorice root tea?
Possible signs of excess licorice root exposure include swelling, headaches, muscle weakness or cramps, and a raised blood pressure reading. These symptoms are not specific to licorice root, and high blood pressure or low potassium may occur without obvious symptoms.
If you develop symptoms or learn that your blood pressure is high or your potassium is low, stop drinking licorice root tea and contact a clinician promptly. Seek urgent medical help for chest pain, fainting, severe weakness, or a rapid or irregular heartbeat.
Be especially careful if you have high blood pressure, heart or kidney disease, or a history of low potassium. Avoid regular licorice root tea unless your clinician advises that it is appropriate for you. If you are pregnant, avoid licorice root tea; if you are breastfeeding or considering it for a child, ask a clinician first.
Licorice root can also be a concern with medicines such as diuretics, blood pressure medicines, corticosteroids and digoxin. Ask your clinician or pharmacist about the specific product you use, and do not stop or change prescribed medication on your own.
Frequently asked questions
Does brewing licorice root tea for less time make it safe?
A shorter brew may change the amount extracted, but it does not establish a safe glycyrrhizin level. Product strength and individual risk still vary.
Is deglycyrrhizinated licorice root tea risk-free?
Deglycyrrhizinated licorice products are made to reduce glycyrrhizin, but that does not prove a particular tea is risk-free. Check the product label and ask a clinician or pharmacist if you need to avoid glycyrrhizin.
Can licorice root in a tea blend add to my exposure?
Yes. Licorice root in a blend can contribute glycyrrhizin even when it is not the main ingredient, so check the full ingredient list.
