These unique properties make mulethi a versatile herb beneficial for a wide array of health conditions.

Botanical Description of Mulethi

Mulethi (Glycyrrhiza glabra) belongs to the Fabaceae (Leguminosae) family and is a perennial herbaceous plant that thrives in temperate regions. It is characterized by:

• Roots: The most valuable part of the plant, the roots are long, cylindrical, and fibrous, with a sweet taste due to the presence of glycyrrhizin.
• Stem: A woody, erect, and branched structure that can grow up to 1–1.5 meters in height.
• Leaves: The leaves are compound and pinnate, with 9–17 small leaflets, each being oval or lanceolate in shape. They have a slightly sticky texture due to secreted resinous compounds.
• Flowers: Mulethi produces pale violet to blue-colored flowers, arranged in axillary racemes, which bloom during the summer months.
• Fruits and Seeds: The plant bears small, flattened, oblong pods, each containing 2–5 seeds. The pods have a leathery texture and turn brown when mature.

Habitat and Geographical Distribution of Mulethi

Mulethi is native to Asia and parts of Europe and is widely cultivated for its medicinal properties. It thrives in:

• Temperate and subtropical regions, especially in countries like India, Iran, Afghanistan, Pakistan, China, Turkey, and parts of Europe.
• Sandy, loamy, and well-drained soils, preferably in regions with moderate rainfall and full sunlight exposure.
• Riverbanks, plains, and foothills, where moisture retention is optimal for root development.

In India, farmers predominantly cultivate mulethi in Punjab, Uttar Pradesh, and parts of Rajasthan. Due to its extensive demand in Ayurvedic medicine, they are making efforts to promote sustainable cultivation and conservation of this valuable herb.

Chemical Composition of Mulethi

Mulethi owes its medicinal efficacy to a rich and diverse chemical profile. The primary bioactive constituents include:

• Glycyrrhizin: A triterpenoid saponin responsible for the characteristic sweet taste and anti-inflammatory properties.
• Flavonoids: Including liquiritin and isoliquiritin, known for their antioxidant and hepatoprotective effects.
• Coumarins: Such as herniarin and umbelliferone, which exhibit antimicrobial and anti-inflammatory activities.
• Polysaccharides: Contributing to immune modulation and mucosal protection.
• Essential Oils: Containing anethole, which provides antispasmodic and expectorant effects.
• Isoflavones: Plant-derived compounds with phytoestrogenic properties that support hormonal balance.

This diverse chemical composition underlies the therapeutic potency of mulethi across various Ayurvedic formulations.

Useful Part of Mulethi

The most useful part of the mulethi plant is its root. The dried roots and rhizomes are primarily harvested for medicinal use. These parts contain the highest concentration of bioactive compounds responsible for its therapeutic effects. In Ayurvedic medicine, practitioners use the powdered root or root extracts in various formulations, including decoctions, herbal teas, ointments, and capsules. They prefer the root for its sweet taste and healing properties in treating respiratory, digestive, and skin-related ailments.
