Chemical Composition and Nutritional Profile

Licorice contains a variety of bioactive compounds, including glycyrrhizin, a triterpene glycoside known for its potent anti-inflammatory and antiviral properties, along with flavonoids such as liquiritigenin and isoliquiritin, which contribute to its antioxidant and anti-cancer effects.

It also contains alkaloids like glabridin and essential oils rich in terpenes, which support its traditional use in respiratory and digestive health. Nutritionally, licorice is a good source of vitamins such as vitamin C and B-complex vitamins, as well as minerals like potassium, magnesium, and calcium, making it a nutrient-dense herb. The mechanism of action of licorice involves modulating immune responses, reducing inflammation through inhibition of pro-inflammatory cytokines, and protecting cells from oxidative stress due to its high antioxidant content.

Its complex chemical profile makes it valuable in both traditional medicine and modern pharmacological research.

Medicinal Properties and Health Benefits

Glycyrrhiza uralensis has been widely recognized for its potent medicinal properties, primarily due to its high concentration of glycyrrhizin, a compound with anti-inflammatory, antiviral, and immunomodulatory effects.

It supports the respiratory system by alleviating symptoms of coughs, bronchitis, and asthma, while also benefiting the digestive system by soothing ulcers and reducing inflammation in the stomach lining. Compared to similar herbs like licorice root (Glycyrrhiza glabra), G. uralensis offers a more pronounced anti-inflammatory action and greater potency in treating respiratory infections, though it may have a higher risk of side effects such as hypertension due to its glycyrrhizin content. Its ability to modulate the immune system makes it valuable in managing conditions like hepatitis and autoimmune disorders.

Overall, glycyrrhiza uralensis stands out for its broad therapeutic applications across multiple body systems, making it a preferred choice in traditional and modern herbal medicine.

Forms, Preparation and Usage

Glycyrrhiza uralensis has been widely used in traditional medicine for its therapeutic properties, and it is available in various forms such as fresh root, dried root, tincture, powder, essential oil, and capsule.

The most common preparation methods include making a tea by steeping the dried root in hot water, decocting it for a stronger extract, or using it in an infusion for milder effects. It can also be applied topically as a poultice or ointment for skin conditions. The recommended dosage for adults is typically 200-500 mg of standardized extract in capsule form, taken two to three times daily, while children should only use it under medical supervision due to potential side effects.

Usage should be conservative, with a duration of no more than two weeks unless directed by a healthcare professional.

Safety, Side Effects and Contraindications

Glycyrrhiza uralensis can be a valuable medicinal plant used for its anti-inflammatory, antiviral, and expectorant properties, but it must be used with caution due to its potential side effects.

Prolonged use may lead to hypertension, fluid retention, and electrolyte imbalances due to its mineralocorticoid-like effects, which can mimic the action of aldosterone. It may interact with medications such as diuretics, antihypertensives, and corticosteroids, potentially increasing the risk of adverse effects. Special populations, including pregnant and breastfeeding women, should avoid long-term use due to possible risks to fetal or infant development, while individuals with chronic conditions like heart disease or kidney disorders should consult a healthcare provider before use.

To ensure safety, it is advisable to use glycyrrhiza uralensis in short-term, low-dose formulations and under the supervision of a qualified healthcare professional.

Growing, Harvesting and Storage

Glycyrrhiza uralensis grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, in full sun to partial shade, and requires consistent moisture without waterlogging.

It thrives in temperate climates and should be planted in early spring after the last frost, with rows spaced 30-60 cm apart to allow adequate air circulation. Regular watering is essential during the growing season, but care must be taken to avoid overwatering, which can lead to root rot. For optimal care, mulching around the base of the plant helps retain soil moisture and suppress weeds, while periodic pruning of old or diseased foliage promotes healthy growth. Harvesting is best done in late summer to early autumn when the roots are most mature, using a spade to carefully dig up the roots without damaging them. After harvesting, the roots should be thoroughly washed, cut into smaller pieces, and dried in a shaded, well-ventilated area or using a dehydrator to preserve their potency.

Proper storage involves placing the dried roots in airtight containers and keeping them in a cool, dark, and dry place to maintain their medicinal properties for extended periods.
