Licorice root Safety Guide: Cautions, Contraindications and Sensible Doses

The question behind every search for Licorice root is usually is it safe, and the honest answer has conditions. Here they are, laid out plainly.

What the research says about safety

Worth knowing before you start: even small amounts of glycyrrhizin from licorice root products have been linked to severe adverse effects in people who consume a lot of salt, in people with hypertension, and in people with heart or kidney conditions. Oral licorice products that do not contain glycyrrhizin (deglycyrrhizinated licorice) might be safe for up to 4 months. Topical licorice root may be safe to use in the short term, but it may cause skin irritation in some people. Manufacturers and distributors of supplements are responsible for evaluating the safety and labeling of their products before marketing to ensure that they meet all regulatory requirements.

The traditional warnings

Chinese medicine has its own caution list, based on the herb's nature rather than trials: long heavy use raises blood pressure and lowers potassium; keep regular concentrated intake short. A practitioner checks your pattern before prescribing precisely for this reason.

Common-sense rules

Keep to food-level amounts unless a practitioner says otherwise, take breaks rather than running any herb continuously for months, and stop at the first sign that something disagrees with you. If you are pregnant, breastfeeding, on prescription medication or managing a chronic condition, talk to a professional before starting.

None of this replaces a practitioner who can look at your tongue, feel your pulse and ask awkward questions. Use this as background, not as a prescription.
