The Efficacy ofGynura pseudochina DC.var.hispida Thv. Ointment in Treating Chronic Plaque Psoriasis: A Randomized Controlled Trial

Abstract

The GP ointment demonstrated efficacy similar to that of 0.1% TA cream for mild to moderate chronic plaque psoriasis. In addition, its short-term side effects were minimal.

Effectiveness of Online vs In-Person Care for Adults With Psoriasis

“…Studies in psoriasis populations with milder disease severity and using available SD data would have yielded PASI score equivalence margins around ±3 or ±4. 42 , 43 Even if the equivalence margin for PASI scores had been set at ±1, the improvement in psoriasis severity between the 2 groups seen in this study would still be considered equivalent.…”

Antioxidant and Anti-Inflammatory Effects of Genus Gynura: A Systematic Review

“…The reporting completeness of the material in all selected studies was assessed using information of the Gynura species material, voucher specimens, quality control, and chemical analysis. Naming inconsistency between studies was detected as full botanical taxonomic names were not stated in 13 selected studies ( Iskander et al, 2002 ; Siriwatanametanon and Heinrich, 2011 ; Akowuah et al, 2012 ; Seow et al, 2014 ; Chao et al, 2015 ; Wong et al, 2015 ; Xu et al, 2015 ; Rerknimitr et al, 2016 ; Yin et al, 2017 ; Rahman et al, 2018 ; Pai et al, 2019 ; Yang et al, 2019 ; Chandradevan et al, 2020 ). All plant species need to be validated taxonomically, and the full names have to be clearly stated as the incomplete name of plant species can lead to confusion of readers and any recorded uses or properties attributed may, in fact, correlate to different species.…”

“…Six selected studies ( Iskander et al, 2002 ; Xu et al, 2015 ; Ma et al, 2017 ; Dong et al, 2019 ; Liu M. et al, 2019 ; Liu Y. et al, 2019 ) reported the information of the Gynura species source but did not provide voucher specimens. Four selected studies ( Siriwatanametanon and Heinrich, 2011 ; Rerknimitr et al, 2016 ; Pai et al, 2019 ; Yang et al, 2019 ) were inadequate on material information as the Gynura species source was not reported and voucher specimens were missing. The absence of voucher specimens seriously makes the reliability of the article suspicious.…”

“…Of the 27 selected studies, there are seven species of genus Gynura , which are G. procumbens , G. bicolor , G segetum , G. divaricata , G. formosana , G. nepalensis , and G. pseudochina. Among these Gynura species, 11 out of 27 selected studies focused on G. procumbens ( Iskander et al, 2002 ; Kim et al, 2011 ; Akowuah et al, 2012 ; Shwter et al, 2014 ; Wong et al, 2015 ; Huang et al, 2019 ; Liu M. et al, 2019 ; Liu Y. et al, 2019 ; Nazri et al, 2019 ; Ning et al, 2019 ; Chandradevan et al, 2020 ), five studies on G. bicolor ( Wu et al, 2013 ; Chao et al, 2015 ; Yin et al, 2017 ; Pai et al, 2019 ; Yang et al, 2019 ), four studies on G. pseudochina ( Siriwatanametanon et al, 2010 ; Siriwatanametanon and Heinrich, 2011 ; Rerknimitr et al, 2016 ; Sukadeetad et al, 2018 ), two studies on G. segetum ( Seow et al, 2014 ; Yuandani et al, 2017 ), two studies on G. nepalensis ( Yu et al, 2016 ; Rahman et al, 2018 ), two studies on G. divaricata ( Xu et al, 2015 ; Dong et al, 2019 ), and one study on G. formosana ( Ma et al, 2017 ) .…”
