Mechanistic basis
This use is associated with the plant's anti-inflammatory action. Further evidence for that pharmacology:
Gout is a disorder that triggers a severe inflammatory reaction which generates episodes of intense pain and discomfort to the patient. Arctium minus (Hill) Bernh. (Asteraceae) is known as "burdock" and displays anti-inflammatory, antinociceptive, against rheumatic pain and radical-scavenging activities. Species of the genus Arctium have been used in assistant therapy of gout and other inflammatory processes. We investigated the antinociceptive and anti-edematogenic effects of the crude extract of A. minus seeds in an acute gout attack model induced by intra-articular injection of monosodium urate (MSU) crystals in adult male Swiss mice (25-30 g). The crude extract of A. minus (100 mg/kg, p.o.) reduced the mechanical allodynia induced by the injection of MSU (1.25 mg/site, i.a.) from 4 until 8 h after its administration. A. minus seeds crude extract prevented mechanical allodynia at doses of 30 and 100 mg/kg, but not 10 mg/kg. Allopurinol (10 µg/mL) and A. minus crude extract (10-300 µg/mL) inhibited the xanthine oxidase activity in vitro. The A. minus seeds crude extract did not cause adverse effects since did not change the toxicological parameters evaluated. A. minus crude extract can be used as an assistant therapy of gout pain, supporting its traditional use, without causing adverse effects.
Ethnopharmacological relevance Arctium minus (Hill) Bernh. ssp. minus (Asteraceae) leaves are used to alleviate rheumatic pain, against fever and sunstroke with externally application in Turkish folk medicine. Aim of the study To evaluate the anti-inflammatory, antinociceptive and antioxidant activities of aqueous and ethanol extracts prepared from the leaves of Arctium minus ssp. minus. Materials and methods The ethanolic and aqueous extracts from the leaves of Arctium minus ssp. minus were evaluated in mice for anti-inflammatory activity using carrageenan-induced hind paw edema model and for antinociceptive activity using p-benzoquinone-induced abdominal contractions test. Moreover, the antioxidant power of the extracts has been determined by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and flow injection analysis-luminol chemiluminescence (FIA-CL). In addition, the total phenolic content in both extracts was determined with spectrophotometric method. Results Our results showed that only the ethanol extract exhibited a dose-dependent anti-inflammatory activity ranging between 11.1 and 23.6% at 200mg/kg dose as well as displayed a significant antinociceptive activity without inducing any gastric damage. Although, both extracts were shown to possess significant DPPH radical-scavenging activity, that of aqueous extract was found to have more pronounced activity. In FIA-CL system, the ethanol extract was shown to possess a significant scavenger activity against H(2)O(2) while the aqueous extract was much more potent antioxidant activity against HOCl-luminol CL than ethanol extract. Conclusion According to our results, it was concluded that Arctium minus ssp. minus contains potent natural antioxidants. In this study, in vivo experimental results have also supported the folk medicinal utilization of Arctium minus ssp. minus.
