Wound healing is a complex biological process which involves four distinct phases like hemostasis, inflammation, proliferation and tissue remodeling. The various phytoconstituents present in the medicinal plants made them a potential wound healing agent. This review summarizes the wound healing potential of medicinal plants based on various phytoconstituents like alkaloids, flavonoids, tannins, saponins, phenolics terpenoids and glycosides present in it, which exhibits antioxidant, antimicrobial, anti-inflammatory, angiogenic and collagen promoting effect.
Globally, wounds particularly chronic wounds are a major source of expense for healthcare systems. According to estimates, at least 2% of people in the United States of America (USA) may suffer from a chronic wound of some kind. According to a study by Queen and Harding, the three nations that spent the most on wound care in 2022—the United States, China, and Japan were expected to have spent $148.65 billion, $42.78 billion, and $22.91 billion, respectively. Additionally, the worldwide wound care market is projected to rise at a compound annual growth rate of 6.1% from 2024 to 2032, reaching $20.33 billion(1).
Both the market for wound care products and the yearly expenditures made by individuals and governments to manage this health issue are growing(1). The majority of the more than 5,000 commercially available wound care products are dressings(2).
Wound healing is a complicated and dynamic biological process with four overlapping phases: hemostasis, inflammation, proliferation, and tissue remodeling(2). This sequence of actions is essential for the complete healing of wounded tissues. Impaired wound healing, particularly in the case of chronic wounds, is a serious issue in clinical practice.
Medicinal plants have long been recognized as valuable resources in traditional medicine systems across the world, owing to their ability to promote wound healing through a wide range of bioactive phytochemicals with minimal adverse effects. These phytochemicals, including flavonoids, alkaloids, tannins, saponins, and phenolic acids, possess potent antioxidant, anti-inflammatory, and antimicrobial activities that collectively enhance the various stages of the wound healing process. Growing scientific interest has led to extensive investigations into the therapeutic potential of underexplored medicinal plants, with the aim of discovering novel, safe, and effective wound healing agents that can complement or serve as alternatives to conventional wound care therapies.
CLASSIFICATION OF WOUND (3)
Wounds are categorized according to several factors, such as their anatomical site, the type and cause of injury, clinical presentation, depth of tissue damage, extent of tissue loss, and morphological characteristics. Depending on the mechanism responsible for their occurrence, wounds are generally classified as either open or closed. Based on the normal progression of tissue repair, they are also grouped into acute wounds, which heal within an expected timeframe, and chronic wounds, which exhibit delayed or impaired healing.
Open wounds are characterized by a break in the skin or underlying tissues, resulting in visible bleeding as blood escapes from the body. These injuries expose the affected tissues to the external environment and are commonly classified into several types, including incisions, lacerations, abrasions, puncture wounds, avulsions, and penetrating injuries such as gunshot wounds. The severity of an open wound depends on the extent of tissue damage and the risk of contamination or infection.
Closed wounds occur when the skin remains intact, but the underlying tissues and blood vessels are damaged. In these injuries, blood leaks from the circulatory system and accumulates beneath the skin without an external opening. Common examples include contusions (bruises), hematomas, and crush injuries. Although the skin surface appears unbroken, significant internal tissue damage may be present.
Acute wounds are injuries that progress through the normal stages of wound healing in a predictable and timely manner. They usually result from surgical procedures, accidental cuts, or other forms of trauma and undergo an orderly sequence of hemostasis, inflammation, proliferation, and remodeling. With appropriate care, acute wounds generally heal completely within the expected period, restoring both the structural and functional integrity of the affected tissue.
Chronic wounds are those that fail to heal within the expected timeframe due to disruption of the normal healing process. These wounds often remain in a prolonged inflammatory phase, delaying tissue regeneration and repair. Factors such as infection, poor blood circulation, diabetes, repeated trauma, or underlying systemic diseases can contribute to their persistence. As a result, chronic wounds may take months to heal, frequently recur, and require specialized management strategies.
THE STAGES OF WOUND HEALING: TARGETS FOR BIOLOGICAL SCREENING(4)
Wound healing is a complex and well-regulated biological process that restores the integrity of injured tissue through four overlapping phases: hemostasis, inflammation, proliferation, and remodeling. Immediately after injury, the skin barrier is disrupted, resulting in blood loss and an increased risk of microbial invasion. During the hemostatic phase, blood clot formation controls bleeding and provides a protective barrier, while proper wound cleansing and antiseptic treatment help prevent infection.
The inflammatory phase involves the recruitment of immune cells and the release of cytokines to eliminate pathogens and remove damaged tissue. This is followed by the proliferative phase, during which fibroblast proliferation, angiogenesis, collagen deposition, and re-epithelialization promote tissue regeneration. Finally, in the remodeling phase, collagen fibers are reorganized, and scar tissue matures, restoring the strength and function of the affected tissue. Therapeutic interventions that support these phases can enhance wound repair and improve healing outcomes.
Fig 1: Four stages of wound healing
Hemostasis is the first phase of wound healing and occurs immediately after injury to prevent excessive blood loss. Local vasoconstriction reduces blood flow at the injury site, while platelet activation and aggregation lead to the formation of a temporary platelet plug. Simultaneously, the coagulation cascade is activated, resulting in the conversion of fibrinogen to fibrin by thrombin. Cross-linking of fibrin strands by factor XIII stabilizes the clot, which seals the wound, limits blood loss, and provides a protective barrier against microbial invasion.
Preventing wound infection is essential for normal healing, as microbial contamination can prolong inflammation and lead to complications such as cellulitis, osteomyelitis, sepsis, and necrotizing fasciitis. Therefore, maintaining an aseptic wound environment is a key aspect of wound management. The most common wound pathogens include Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Enterococcus faecalis, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, and Proteus species, making them important targets for antimicrobial wound therapies.
The inflammatory phase is a critical stage of wound healing that enables the immune system to eliminate pathogens, remove damaged tissue, and initiate repair. Following injury, immune and resident cells, including macrophages, neutrophils, fibroblasts, and epithelial cells, release inflammatory mediators such as cytokines, chemokines, prostaglandins, and leukotrienes. Pro-inflammatory cytokines, including interleukin (IL)-1β, IL-2, IL-6, interferon-γ (IFN-γ), and tumor necrosis factor-α (TNF-α), coordinate the inflammatory response, while anti-inflammatory cytokines such as IL-10 help regulate inflammation and prevent excessive tissue damage. Chemokines, including macrophage inflammatory protein-2 (MIP-2) and monocyte chemoattractant protein-1 (MCP-1), recruit leukocytes to the wound site. Additionally, activation of the arachidonic acid pathway through cyclooxygenase (COX) and lipoxygenase (LOX) enzymes generates prostaglandins and leukotrienes, further modulating the inflammatory process. Together, these coordinated events prepare the wound for the subsequent stages of tissue repair and provide important therapeutic targets for enhancing wound healing.
The proliferative phase is characterized by rapid tissue regeneration and restoration of the wound structure. During this stage, chemokines, cytokines, and growth factors stimulate fibroblast migration and proliferation through signaling pathways such as MAPK, YAP, and TGF-β. Fibroblasts synthesize collagen and other extracellular matrix (ECM) components, forming a scaffold for new tissue development. Some fibroblasts differentiate into myofibroblasts, which promote wound contraction and facilitate closure of the injured area. These coordinated processes are essential for effective tissue repair and regeneration.
The remodeling phase is the final stage of wound healing, during which the newly formed tissue undergoes maturation and reorganization to improve its strength and functionality. This phase may continue for several months or even years. Type III collagen is gradually replaced by the stronger type I collagen, while the extracellular matrix is reorganized to enhance tissue integrity. Continued myofibroblast-mediated wound contraction and collagen remodeling result in the formation of mature scar tissue with increased tensile strength.

These phytochemicals contribute to its diverse pharmacological properties, including antimicrobial, antidiabetic, antivirulent, antifertility, antioxidant, hepatoprotective, hypoglycemic, lipid-lowering, antidote, antidepressant, and wound healing activities(11).
Ethanolic extracts of the plant have been reported to significantly reduce blood glucose levels in streptozotocin-induced diabetic rats, demonstrating its potential antidiabetic activity. Additionally, topical application of chloroform and methanolic extracts of the root and shoot showed notable wound healing effects, as evidenced by increased hydroxyproline content, tensile strength, and dry weight of granulation tissue in incision wound models. Due to these therapeutic properties and the presence of bioactive phenolic compounds, the plant was selected for evaluating its wound healing potential in diabetic animal models(11).
The precise mechanism by which Mimosa pudica (lajwanti) extract enhances wound repair and regeneration remains unclear; however, several pathways may contribute to its activity. The extract promotes collagen, hexosamine, and DNA synthesis, which are essential for tissue regeneration. Its wound healing effect may also be associated with the reduction of oxidative stress, as evidenced by increased glutathione (GSH) levels, enhanced catalase and superoxide dismutase (SOD) activities, and decreased lipid peroxidation. The extract may regulate inflammatory responses by modulating NF-κB activation and stimulating the production of growth factors and cytokines, including PDGF, TGF-β, and VEGF, which support cell proliferation and tissue repair. Increased antioxidant activity suggests possible activation of the Nrf2 pathway, which helps control excessive inflammation during wound healing. These effects may be attributed to the presence of bioactive constituents such as flavonoids (quercetin, luteolin, and rutin) and mimosine present in the extract(12).
Murraya koenigii, commonly known as curry leaf, belongs to the family Rutaceae and is valued for its characteristic aroma and medicinal properties. The plant contains various bioactive compounds, including alkaloids, phenolic compounds, quercetin, saponins, polypeptides, and steroids, which contribute to its therapeutic potential.

Phytochemical investigations of M. annua have revealed the presence of glycosides, tannins, carbohydrates, phenolic compounds, flavonoids, and anthocyanins. Specific bioactive compounds identified include cyanidin-3-galactoside in flowers, p-hydroxybenzoic acid, sinapic acid, and gentisic acid in leaves and fruits, chlorogenic acid in leaves, and fatty acids in seeds(40). Additionally, ethanol extracts of M. annua leaves have shown anti-inflammatory and wound-healing activities in animal models, demonstrating their potential in promoting tissue repair(41).
Aloe vera (L.) Burm. f. belonging to the family Liliaceae, is one of the most extensively studied medicinal plants due to its therapeutic potential, particularly in skin disorders(42). Traditionally known as the “plant of immortality,” A. vera has been used in various cultures to treat burns, wounds, psoriasis, dermatitis, and infections(43). Numerous in vitro, in vivo, and clinical studies have confirmed its wound-healing properties through different preparations, including gel, latex, juice, and extracts. The healing activity is attributed to the synergistic effects of bioactive constituents such as polysaccharides, acemannan, aloin A and B, and emodin, which promote wound repair through antioxidant, anti-inflammatory, antimicrobial, and tissue-regenerative mechanisms(44),(45). Although the gel and leaf extracts are well studied, A. vera flowers, containing compounds such as apigenin glycoside derivatives with antioxidant and anti-inflammatory properties, remain comparatively less explored for cutaneous wound healing(43).
Aloe vera (L.) Burm. f. is a medicinal plant with diverse pharmacological properties, including anti-inflammatory, antibacterial, antioxidant, hypoglycemic, and wound-healing activities(46),(47). Studies in animal models have demonstrated that A. vera gel accelerates wound repair by reducing inflammation, promoting fibroblast proliferation, collagen synthesis, wound contraction, re-epithelialization, angiogenesis, and enhancing growth factors such as TGF-β1 and VEGF(48). Bioactive compounds such as β-sitosterol and aloesin have been reported to stimulate endothelial cell proliferation and migration, thereby supporting angiogenesis and tissue regeneration. The fresh leaves contain anthraquinone-rich yellow latex and a clear mucilaginous gel composed mainly of water, polysaccharides (including glucomannan and acemannan), proteins, vitamins, minerals, and other bioactive constituents responsible for its therapeutic effects(48).
The polysaccharides and glycoproteins present in the leaf pulp of Aloe vera (L.) Burm. f. contributes significantly to its wound-healing and anti-inflammatory activities. The healing effect is primarily attributed to glucomannan, which enhances fibroblast proliferation and activity, thereby promoting collagen synthesis and secretion(49). Additionally, A. vera extracts exhibit antimicrobial properties due to bioactive compounds such as lupeol, salicylic acid, urea nitrogen, cinnamic acid, phenols, and sulfur, which show inhibitory effects against bacteria, fungi, and viruses. Enzymes present in A. vera, including amylase, lipase, and carbopeptidase, also contribute to its therapeutic effects by aiding digestion and reducing inflammation through bradykinin inactivation(49).
Copaifera L. belongs to the family Fabaceae, tree native to Central and South America, and Africa. Various studies have investigated the pharmacological properties of Copaifera extracts, particularly hydroalcoholic leaf extracts and copaiba oleoresin, demonstrating their potential therapeutic applications(49).
The oleoresin of Copaifera L. contains abundant bioactive terpenoids, particularly sesquiterpenes and diterpenes such as β-caryophyllene, α-humulene, β-bisabolene, caryophyllene oxide, copalic acid, kaurenoic acid, and hardwickiic acid. These compounds contribute to wound healing through their anti-inflammatory, antimicrobial, antioxidant, and tissue-regenerative activities by promoting collagen deposition, re-epithelialization, and protection against microbial infection(50),(51).
The pharmacological effects of Copaifera L. oleoresin are mainly attributed to its high sesquiterpene content, which constitutes more than 90% of its composition. However, its therapeutic activity is not related to a single compound but results from the synergistic interactions among multiple bioactive constituents. Studies have demonstrated that copaiba oil exhibits antibacterial, anti-inflammatory, and anti-psoriatic activities. Additionally, Copaifera langsdorffii oleoresin showed no cytotoxic effects on fibroblasts at 100 µg/mL and promoted wound healing in rabbit and rat models, indicating its potential as a wound-healing agent(51).

The flowers of Calendula officinalis L. contain several bioactive constituents, including triterpenoids, saponins, flavonoids, carotenoids, fatty acids, polysaccharides, and essential oils. Although the levels of these compounds may vary depending on geographical origin, the therapeutic effects of topical C. officinalis preparations remain consistent. In vitro studies have demonstrated the cytotoxic and tumor-inhibitory potential of C. officinalis extracts against various cancer cell lines, including cervical, breast, leukemia, prostate, and fibrosarcoma models. Traditionally, C. officinalis has also been used internally for managing gastrointestinal conditions such as peptic and duodenal ulcers, gastritis, colitis, and mucosal inflammation(65),(66).
In Ayurvedic medicine, Calendula officinalis L. is recognized for its scar-reducing and emollient properties, which are associated with enhanced collagen metabolism and increased angiogenesis at wound sites. Studies have demonstrated that C. officinalis flower extract can improve scar reduction and skin-softening effects(67). Experimental investigations using ethanolic, hexane, and dichloromethane fractions of C. officinalis have shown significant wound-healing and angiogenic activities, with ethanolic extract promoting new blood vessel formation and reducing wound size compared with control treatments(68).
Studies have demonstrated that Calendula officinalis L. extract enhances epithelialization in chronic venous ulcers and promotes wound repair in burn models. Treatment with ethanolic flower extract improved healing by increasing collagen hydroxyproline and hexosamine levels, while reducing tissue damage markers, acute-phase proteins, and lipid peroxidation through its antioxidant activity(69). The ethanolic extract also enhances collagen synthesis and blood circulation at wound sites(70). Due to its antimicrobial, antioxidant, antiseptic, and anti-inflammatory properties, C. officinalis gel and ointment preparations have shown improved wound healing and are suitable for topical application because of their stability, skin penetration, and ease of use(71).
Although the wound-healing mechanisms of Calendula officinalis L. are not completely understood, studies have shown that its extracts promote fibroblast migration and proliferation through a PI3K-dependent pathway. Flower extracts of C. officinalis enhance granulation tissue formation by regulating the expression of connective tissue growth factor (CTGF) and α-smooth muscle actin (α-SMA) in excisional wound models. Additionally, C. officinalis has been reported to stimulate angiogenesis, as demonstrated in chicken chorioallantoic membrane assays and rat skin wound-healing models(71).
