1.Mulethi (Licorice) — At a Glance
Mulethi, scientifically known as Glycyrrhiza glabra, is a revered perennial herbaceous plant. It belongs to the Fabaceae family and is commonly recognized as Licorice. It is native to Southern Europe and parts of Asia. Its range includes regions from the Mediterranean to western China and Central Asia. Its name 'Glycyrrhiza' originates from Greek and literally means 'sweet root,' a testament to its characteristic flavor. This robust herb typically grows up to 1 to 1.5 meters tall.
It features a deep, extensive root system that includes both a primary taproot and numerous stolons or runners. These roots are the primary source of its medicinal value. The plant has pinnate leaves with 9-17 leaflets. In summer, it produces delicate purplish-blue to pale white flowers arranged in upright axillary racemes. Glycyrrhiza glabra thrives in deep, fertile, well-drained loamy soils with a slightly alkaline pH. It prefers warm, sunny climates.
Its widespread distribution and adaptability have led to commercial cultivation in numerous countries. These include Italy, Spain, Greece, Turkey, Iran, India, and China. This has cemented its status as one of the most commercially significant medicinal plants globally. The pharmaceutical, food, and cosmetic industries all use it.
