Psoriasis (Pso) is an autoimmune inflammatory skin disease characterized by red plaques covered in silver scales. The existing treatments provide limited benefits and are associated with certain drawbacks which limit their use. Thus, there a need to explore more options that highly target-specific minimal side effects. Researchers have thoroughly investigated the use of herbal drugs for therapeutic potential. Preclinical studies demonstrate phytochemicals such as curcumin, psoralen, dithranol antipsoriatic These phytoconstituents inhibit signalling pathways, interleukin (IL) 23/Th17 axis IL-36 loop involved pathogenesis Pso. down-regulate pro-inflammatory cytokines like IL-17 tumor necrosis factor (TNF)-α. However, application clinical settings due poor bioavailability access target sites. Combining modern delivery platforms nanocarriers can address these shortcomings improve efficacy. This review explores potential remedies substitute conventional therapies, emphasizing trials conducted medicines. paper supported discussion on liposomes, niosomes, emulsomes, ethosomes, nanostructured lipid carriers, nanoemulsions, dendrimers used deliver

ABSTRACT Potential therapies for wound management remain one of the most challenging affairs to date. Biopolymer hydrogels possess inherent properties that facilitate healing damaged tissue by creating a supportive and hydrated environment. Chitosan/fibroin were formulated with poly (vinyl pyrrolidone) cross‐linked using 3‐aminopropyl (diethoxy) methylsilane (APDEMS) aforementioned function. The characterized through Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, their swelling response was observed variety solvents. Additionally, investigated biomedical applications. As amount fibroin added increased, ratio decreased. analysis chorioallantoic membrane (CAM) assay revealed higher concentrations in hydrogel directly correlated increased angiogenesis. intragroup comparison showed vascular number CPF5 group significantly ( p ≤ 0.05) compared other groups. efficiency prepared rate reduction (99.06%) remarkably high greater content against control (67.03%). Histological findings wounded tissues corroborate abovementioned results, showing dense fibrous connective control. results this work provide thorough preclinical evidence chitosan‐fibroin biopolymers are involved enhanced angiogenesis growing chicks speed up mice without any obvious toxicity.

Phytochemicals, which are predominantly found in plants, hold substantial medicinal value. Despite their potential, challenges such as poor oral bioavailability and instability the gastrointestinal tract have limited therapeutic use. Traditional intra/transdermal drug delivery systems offer some advantages over administration but still suffer from issues penetration depth, slow release rates, inconsistent absorption. In contrast, microneedles (MNs) represent a significant advancement by providing precise control phytochemical enhanced capabilities. By circumventing skin barriers, MNs directly access dermal layers rich blood vessels lymphatics, thus facilitating efficient delivery. This review extensively discusses obstacles of traditional benefits routes with particular focus on transformative potential for explores complexities delivering phytochemicals through routes, development types innovative tools, optimal design properties effective Additionally, this examines versatile applications MN-mediated delivery, including its role administering phytophotosensitizers photodynamic therapy, concludes insights into relevant patents future perspectives.
