Summary

Polygonatum verticillatum is a medicinal herb used in food and folk medicine in China and India, demonstrating antioxidant, antimicrobial, and analgesic properties [PMID:34507763, PMID:38859915, PMID:24081628, PMID:22459478, PMID:19853648].

Background

Polygonatum verticillatum (L.) All. is a member of the Asparagaceae family [PMID:34539117]. It is an endangered medicinal herb found in the Himalayas and Europe [PMID:37346388, PMID:19470110].

Traditional uses

The herb is used as food (drinks, vegetables, snacks, staple, and seasoning foods) and as folk medicine in China and India [PMID:31898384, PMID:38859915]. It is an ingredient in Ashtawarga and Ayurvedic formulations, including Chyavanprash [PMID:27833896, PMID:34539117]. Traditional uses include treating painful conditions, as a plant diuretic, for asthma, and for inflammation [PMID:19853648, PMID:21254271, PMID:23109174].

Active compounds

Identified constituents include saponins, alkaloids, flavonoids, and homoisoflavonoids [PMID:23552263, PMID:30334349]. Specific compounds isolated from rhizomes include diosgenin, santonin, and quinine [PMID:24081628, PMID:27833896]. Other reported components include rutin, quercetin, kaempherol, $\beta$-sitosterol, and various amino acids such as lysine, serine, and aspartic acid [PMID:31898384, PMID:34539117].

Mechanism of action

The herb's spasmolytic effect is mediated through the activation of K+ channels, as evidenced by antagonism with glibenclamide [PMID:24215061]. Bronchodilatory activity is associated with Ca2+ channel blocker-like activity [PMID:23109174]. Anti-inflammatory effects are linked to the inhibition of lipoxygenase (LOX) [PMID:23552263, PMID:23895558, PMID:23109174].

Clinical evidence

Evidence DPain/Nociception

Rhizome and aerial extracts demonstrated significant antinociceptive activity in rodent models (acetic acid, formalin, and hot plate tests) [PMID:19853648, PMID:21254271]

Evidence DPyrexia (Fever)

Rhizomes and aerial parts evoked prominent antipyretic activity in a dose-dependent manner in yeast-induced pyrexia models [PMID:22610947]

Evidence DMicrobial Infections

Rhizome extracts showed broad-spectrum antibacterial activity, particularly against Gram-negative bacteria (E. coli, S. typhi, S. flexneri) [PMID:22459478, PMID:25553804, PMID:30334349]

Evidence DAirway Hyperactivity/Asthma

Rhizome and aerial extracts exhibited tracheorelaxant and bronchodilator activities in isolated guinea-pig and rabbit tracheal preparations [PMID:23895558, PMID:23109174]

Evidence DInflammation

Extracts reduced paw edema in carrageenan-induced rat models and inhibited lipoxygenase [PMID:23895558, PMID:23109174]

Evidence D

Evidence summary

The current evidence is based entirely on in vitro studies and animal models (Level D). While promising results for analgesic, anti-inflammatory, and antimicrobial activities are noted, there are no human clinical trials provided in the source material.
