“…After applying linseed oil to second-degree burns in rats, a higher wound closure rate was observed, and the performed biopsy showed better tissue regenerative properties and higher angiogenesis than the control [ 80 ]. In another study, also on the model of second-degree burns in rats, it was confirmed that after 21 days of linseed oil application, the severity of the inflammatory process decreased, and collagen synthesis, re-epithelialization, and angiogenesis increased [ 81 ]. In a burn model in rabbits, after 12 days of treatment with linseed oil, the degree of wound closure was significantly higher than in the control group; moreover, complete wound closure was 9 days earlier than in the control group.…”
Skin disorders of different etiology, such as dermatitis, atopic dermatitis, eczema, psoriasis, wounds, burns, and others, are widely spread in the population. In severe cases, they require the topical application of drugs, such as antibiotics, steroids, and calcineurin inhibitors. With milder symptoms, which do not require acute pharmacological interventions, medications, dietary supplements, and cosmetic products of plant material origin are gaining greater popularity among professionals and patients. They are applied in various pharmaceutical forms, such as raw infusions, tinctures, creams, and ointments. Although plant-based formulations have been used by humankind since ancient times, it is often unclear what the mechanisms of the observed beneficial effects are. Recent advances in the contribution of the skin microbiota in maintaining skin homeostasis can shed new light on understanding the activity of topically applied plant-based products. Although the influence of various plants on skin-related ailments are well documented in vivo and in vitro, little is known about the interaction with the network of the skin microbial ecosystem. The review aims to summarize the hitherto scientific data on plant-based topical preparations used in Poland and Ukraine and indicate future directions of the studies respecting recent developments in understanding the etiology of skin diseases. The current knowledge on investigations of interactions of plant materials/extracts with skin microbiome was reviewed for the first time.

“…Generally, the studies have proven the efficacy of using linen or flax oil to promote wound healing [ 95 , 96 , 97 , 98 , 99 , 100 , 101 ]. There exist some conflicting studies that have not shown much beneficial effect [ 102 , 103 ] and a concern of specific preparations of linen that may induce dermal irritation [ 99 ]. However, the majority of evidence would support the continued use of linen in promoting wound healing.…”
The inclusion of flaxseed in the diet may have a great number of potential
benefits for the well-being of both healthy individuals and those challenged by
disease conditions as well. With an increase in the number and quality of studies
focused on the physiological and pathophysiological effects of dietary flaxseed,
our knowledge concerning the rationale for the inclusion of flaxseed in our diet
has become more convincing and stronger. The purpose of this review is threefold.
First, the review will comprehensively document the evidence supporting the value
of dietary flaxseed to improve bodily health in both normal and disease
conditions. Second, this review will identify the mechanisms of action
responsible for these effects. Finally, this article will review practical
aspects relevant to the inclusion of flaxseed in the diet. Briefly, supplementing
the diet with flaxseed has beneficial effects on the treatment and/or prevention
of different kinds of cardiovascular disease (hypertension, ischemic heart
disease, myocardial infarcts, atherosclerosis), non-alcoholic fatty liver
disease, breast cancer, bone strength, menopause, diabetes, and wound healing.
Although some controversy exists on the component within flaxseed that provides
these beneficial actions, it is likely that the rich content of the omega-3 fatty
acid, alpha linolenic acid, is primarily responsible for the majority of these
biological effects. It is concluded that the constantly expanding evidence in
support of the inclusion of flaxseed in our daily diet to provide significant
health benefits strongly encourages the initiation of additional work on dietary
flaxseed in order to both confirm past findings as well as to further advance our
knowledge regarding the important biological actions of dietary flaxseed.
“…Furthermore, wounds caused by burns with reduced skin resistance as a physical barrier cause pain and enhanced sensitivity. 7 In order to alleviate these problems, dressings in the form of films, hydrogels, composites and sprays are used to protect the injury site and improve wound healing processes. 8 Traditional wound dressings such as cotton, bandages, wool, and gauze have limitations, including the low absorption of exudates, penetration by pathogens and required removal of the materials post-healing, resulting in disruption of the healed skin tissue.…”

“…In addition, wound healing processes can be impaired by certain pathological conditions, including diabetes mellitus, which is projected to affect around 439 million people worldwide by 2030. Furthermore, wounds caused by burns with reduced skin resistance as a physical barrier cause pain and enhanced sensitivity 7 …”
The skin is the largest organ in the human body and its physical integrity must be maintained for body homeostasis and to prevent the entry of pathogenic microorganisms. Sodium alginate (SA) and polyvinyl alcohol (PVA) are two polymers widely used in films for wound dressing applications. Furthermore, blends between SA and PVA improve physical, mechanical and biological properties of the final wound healing material when compared to the individual polymers. Different drugs have been incorporated into SA/PVA-based films to improve wound healing activity. It is noteworthy that SA/PVA films can be crosslinked with Ca 2+ or other agents, which improves physicochemical and biological properties. Thus, SA/PVA associations are promising for the biomedical field, as a potential alternative for wound treatment. This review focuses on the main techniques for obtaining SA/PVA films, their physical-chemical characterization, drug incorporation, and the advantages and challenges of these films for wound healing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
