“…The serum level of TGF-β was also significantly higher in the group treated with Ganoderma lucidum extract, compared to the control group ( 42 ). TNF-α expression was significantly lower in ulcers treated with extracts of Chamomilla recutita, Salvadora persica and Koyanqing Granule formula, compared to controls ( 30 , 32 , 44 ). VEGF expression was significantly lower in ulcers treated with Salvadora persica extract and higher in ulcers treated with propolis extract, compared to their respective controls ( 30 , 37 ).…”

“…The extracts used to treat oral ulcers were herbal ( 34 , 35 , 39 , 42 , 43 , 45 - 48 ), the fungus Ganoderma lucidum ( 40 ), propolis ( 37 ) and curcumin ( 33 , 44 ). The plants used were of the species Musa acuminate ( 34 , 42 ), Aloe barbadensis Miller ( 45 , 38 , 48 ), Matricaria / Chamomilla recutita ( 42 ), Malva sylvestris ( 46 ), Piper sarmentosum ( 35 ), Jasminum grandiflorum ( 31 ), Ficus deltoidea ( 41 ), Salvadora persica ( 30 ), Cannabis sativa ( 38 ), Bletilla striata ( 36 ) and the herbal formula, Kouyanqing Granule (KYQG) ( 32 ).…”

“…The physiopathology of oral ulcers is complex and comprises vasodilatation, cytokine production, cell death, and tissue repair and remodelling ( 50 ). Observations at the molecular level include over-expression of VEGF; over-expression of BAX; marked deposit of collagen fibers in the repair process ( 30 , 37 ); and an increase in both pro-inflammatory and anti-inflammatory cytokines ( 30 , 32 , 37 , 40 , 43 , 48 ). The 84% of the studies selected reported a positive effect of the treatments on the variables evaluated.…”

“…Extract of Malva sylvestris at 20% produced no significant reduction in the area of the oral ulcer, and no positive effect on re-epithelialization of the palatal mucosa in comparison with the control group treated with placebo ( 46 ). Extracts of Jasminum grandiflorum ( 29 ), Bixina orellana ( 45 ), Musa acuminata stem ( 32 , 40 ), Bletilla striata ( 34 ), curcumin ( 42 ), Ficus deltoidea , and Pi per sarmentosum were effective in accelerating the repair process; authors observed greater contraction of the ulcer, greater re-epithelialization ( 31 , 31 , 44 , 47 ), greater production of factors which accelerate cicatrisation ( 34 ), less severe inflammation ( 37 ), and better healing rates on days 7 ( 36 , 44 ) and 14 ( 44 ). The results with no significant differences obtained by Kovalik et al .…”

Background To evaluate the clinical and histopathological effects of natural extracts in the treatment of oral ulcers induced in animal experimental models. Material and Methods We carried out a search in the Medline, Scopus, WoS and Embase databases from the start of the databases to December 2020, and also made a manual search of the references. The search and selection were carried out by two researchers independently. The inclusion criteria were: experimental studies in animal models, in english, which complied with the study object. Results A total of 705 articles were identified. After selection by title, abstract and full text, 19 articles were finally included. Natural extracts of Jasminum grandiflorum , Ficus deltoidea , curcumin and Bixina orellana provoked a significantly greater reduction in the size of the ulcer. Extracts of Salvatora persica , Musa acuminate , Ganoderma lucidum mycelia and Bixina Orellana , as well as preparations of Kouyanqing Granule and curcumin, were able to reduce levels of pro-inflammatory cytokines and increase the expression and serum levels of growth factors and anti-inflammatory cytokines. Extracts of Piper sarmentosus , Cannabis sativa and Bletilla striata provoked a reduction in the severity of the histological inflammation. No significant differences were observed compared to controls in the treatments with extracts of Cannabis sativa , Aloe barbadensus Miller and Malva sylvestris in reducing the area of the oral ulcers. Conclusions Most of the natural extracts described in this review presented a positive clinical and histological effect on the cicatrisation of oral ulcers induced in animal models.
