Standardization, quality control and pharmacological review on Glycyrrhiza glabra L. A potential medicinal herb in Unani and Ayurvedic systems of medicine

ABSTRACT

Glycyrrhiza glabra L. is a potential herbal drug used in Unani and Ayurvedic systems of medicine. In view of the medicinal and pharmacological importance of this species in different systems of medicine, an attempt has been made to provide comprehensive information on standardization and quality control of the herb based on WHO guidelines. The important parameters for standardization and quality control are sensory, macroscopic, microscopic and chemical characteristics along with the physico-chemical characteristics [moisture content, successive extractive value, ash value, acid insoluble ash, water soluble extractive value, acid value, iodine value] and TLC finger prints of different extractives. At the same time, chemical constituents, properties and its uses, pharmacology, precautions and toxicity are discussed based on literature review
