Glycyrrhiza, one of the most widely used Chinese herbal medicines, is a perennial plant with good medicinal value. Polysaccharides as one of the main bioactive components of Glycyrrhiza, mainly composed of arabinose, glucose, galactose, rhamnose, mannose, xylose, and galacturonic acid in different proportions and types of glycosidic bonds. Glycyrrhiza polysaccharides (GP) have many biological activities, such as anti-oxidation, immune regulation, anti-tumor, apoptosis, anti-microbial, anti-inflammatory and regulation of intestinal flora. In this paper, relevant articles on the isolations, structural characterizations, and biological activities of GP published in the last 15 years (2006-2020) were referred to for a systematic review of the species. A total of 947 articles were searched from the database including NCBI, Science Direct, Web of Science, and How Net, and 109 of them were cited on the summarization of the past scientific researches of the polysaccharides of Glycyrrhiza genus. We hope that this work may provide new insights for further study and development of Glycyrrhiza.

Ethnopharmacological Relevance: Shinhyotaklisan (SHTLS) is a time-honored traditional Korean herbal formula composed of four key herbs: Lonicerae Flos, Astragali Radix, Angelicae Gigantis Radix, and Glycyrrhizae Radix et Rhizoma. It has been extensively used to treat inflammatory diseases by expelling excessive heat, detoxifying the body, and promoting the drainage of pus from abscesses.
Aim Of The Study: This study examines the therapeutic effects of SHTLS and elucidates its mechanisms of action in alleviating lipopolysaccharide (LPS)-induced inflammation in vitro.

Ethnopharmacological Relevance: 7,4'-dihydroxyflavone (74DHF), extracted from Gancao (Rhizoma Glycyrrhizae), has demonstrated to mediate the asthma pathology, while Vitamin D3 (VD3) plays a role in asthma treatment due to its immunomodulatory effects. However, the potential molecular or systems mechanism of 74DHF in combination with VD3 against asthma has not yet been elucidated.
Aim Of The Study: The current study not only deepens our understanding of the complex synergistic mechanism of 74DHF andVD3 against asthma but also proposes a promising strategy to promote the development of combination therapy.

Objectives: Polysaccharides from are known to have several bioactive effects. Previous studies have found that low-molecular-weight polysaccharide (GP1) is degraded by and promotes the production of beneficial bacteria and metabolites, which improves immune disorder and intestinal injury, and then enhances the body's immune regulation ability. However, the immune regulation effect of GP1 on a healthy body has not been studied.

Chronic pruritus, or persistent itching, is a debilitating condition that severely impacts quality of life, especially in palliative care settings. Traditional treatments often fail to provide adequate relief or are associated with significant side effects, prompting interest in alternative therapies. This review investigates the antipruritic potential of eight medicinal plants: chamomile (), aloe vera (), calendula (), curcumin (), lavender (), licorice (), peppermint (), and evening primrose ().
