The Role of Boron in Wound Healing

Does Boron Help With Wound Healing?


Have you ever experienced a cut or a burn that seems to take an eternity to heal? The skin doesn't appear to repair itself as quickly as one would expect, leaving you to wonder why. While there are numerous reasons for slow wound healing, one overlooked factor could be a boron deficiency.

Let's explore and discuss this essential trace mineral's role in the wound healing process today.

To comprehend how boron deficiency affects wound healing, it's first essential to understand what happens when our body heals a wound. Upon injury, our body goes through a well-orchestrated process of inflammation, tissue formation, and remodeling. All these stages are underpinned by the body's efficient use of vitamins, minerals, and nutrients, with boron playing a critical role.

Understanding Slow Wound Healing

Before delving into further details, it's pivotal to understand the signs indicative of slow wound healing and to know the circumstances under which these signs should elicit concern.

Awareness of these signs is the first step to addressing underlying issues and deploying appropriate measures to enhance wound recovery.

Typically, a wound goes through several healing phases, including the migration of inflammatory cells into the wound (chemotaxis) and the promotion of the inflammatory process.

This phase is characterized by the sequential infiltration of neutrophils, macrophages, and lymphocytes. However, signs suggesting slow wound healing may manifest when these natural processes are impeded.

These include persistent redness, which is expected during the early stages, but if it continues, it might indicate ongoing inflammation and slow healing, potentially leading to tissue damage.

Similarly, an excessive and continuous swelling could also be a telltale sign of delayed wound healing during the proliferative phase. Macrophages play a crucial role in the wound-healing process by inducing and clearing apoptotic cells, thus paving the way for the resolution of inflammation.

As macrophages clear these apoptotic cells, they undergo a phenotypic transition to a reparative state that stimulates keratinocytes, fibroblasts, and angiogenesis to promote tissue regeneration. The last stage of wound healing is the maturation stage, sometimes called the remodeling stage.

The goal of this stage is to strengthen the repair. Even if your wound is closed and looks healed at the end of the proliferative stage, it takes time for the skin to become strong and more flexible.

By the fourth day, phagocytosis of contaminated tissues is well underway, and the processes of epithelization, collagen deposition, and maturation are occurring. Foreign materials are walled off by macrophages that may metamorphose into epithelioid cells, which are encircled by mononuclear leukocytes, forming granulomas.

Recognizing Slow-Wound Healing

Recognizing and understanding the signs of slow wound healing can be pivotal in seeking timely, appropriate intervention and ensuring optimal recovery.

The body's reparative process is typically efficient, but specific symptoms might indicate a disruption in the healing trajectory.

These signs range from perceptible changes to the wound, such as persistent redness and delayed closure, to more subjective symptoms, such as prolonged pain. It is important to note that wound healing is a dynamic process consisting of four continuous, overlapping, and precisely programmed phases.

The events of each phase must happen in a precise and regulated manner. Interruptions, aberrancies, or prolongation in the process can lead to delayed wound healing or a non-healing chronic wound.

Healing by secondary intention is one of the three main categories of wound healing, along with primary healing and delayed primary healing. Even though different categories exist, the interactions of cellular and extracellular constituents are similar.

Prolonged Redness

While some degree of redness is expected during the early phases of wound healing, persistent or increasing redness could signify an issue. This may be a sign of inflammation, often resulting from the body's natural response to injury. However, when inflammation persists, it can hinder healing and lead to prolonged recovery.


Initial swelling following an injury is typical due to the body's innate inflammatory response. Nevertheless, it could indicate hindered wound healing when the swelling exceeds the average extent or continues significantly longer than expected. This excessive swelling could compromise the optimal healing environment needed for recovery.


Experiencing pain at the wound site is common initially following an injury. However, if the pain persists or intensifies over time, this may indicate that the wound healing process is not progressing as it should.

Persistent pain can interrupt the body's healing ability and may require additional medical attention.

Discharge or Pus

When wound healing is delayed, the susceptibility of the wound to infections increases. This can often lead to the formation of pus or increased wound discharge. Accompanying foul odors are common indicators of disease.

It's crucial to note that these are severe symptoms and should be addressed promptly as they may cause further delay in the healing process.

Delayed Closure

Signs of healing involve the wound progressively closing with the wound edges coming together.

However, if the wound shows no signs of closing or difficulty in wound edges converging as expected, this could strongly indicate slow healing.

Accumulation of Abnormal Scar Tissue

Slow or interrupted wound healing can sometimes pave the way for the development of an excessive amount of scar tissue. This overproduction, known as hypertrophic scarring or keloids, often results in visibly raised and thick scars that are more conspicuous than typical scarring. T

his can affect one's appearance and the proper function of the skin in that area. In the process of fibroplasia and granulation tissue formation, fibroblasts and endothelial cells grow and form a new, provisional extracellular matrix (ECM) by excreting collagen and fibronectin.

Concurrently, re-epithelialization of the epidermis occurs, in which epithelial cells proliferate and 'crawl' atop the wound bed, providing cover for the new tissue. The formation of granulation tissue into an open wound allows the reepithelialization phase to take place, as epithelial cells migrate across the new tissue to form a barrier between the wound and the environment.

They advance in a sheet across the wound site and proliferate at its edges, ceasing movement when they meet in the middle. During this process, new skin begins to form over the granulation tissue, aiding in the wound healing process through tissue growth (cell proliferation).

Additionally, wound contraction occurs, further facilitating the closure of the wound. Collagen production by fibroblasts and myofibroblasts, which are smooth muscle cells, is crucial during the cellular phase of wound healing, as it helps in the alignment of the newly formed matrix and contraction of the wound.

The extracellular space plays a vital role in this process, as the procollagen is secreted into it before being cleaved by peptidases in the cell wall to form true collagen fibrils.

Reopening of the Wound

It's a red flag for delayed or problematic healing if a wound that seemed on the path to recovery suddenly reopens or consistently fails to stay closed. This recurrent dehiscence, often triggered by inadequate initial healing, can prolong recovery and may necessitate additional medical intervention for successful wound management.

Persistent Itchiness at the Wound Site

Extended itching, past the traditional timeline for wound healing, suggests an ongoing inflammatory response and the possibility of delayed wound resolution.

Persistent itchiness can indicate a healing setback and needs attention to avoid discomfort and potential complications that could cause further delay in wound healing.

Abnormal Change in Wound Color

If the color of a wound does not transition as expected—typically from red to pink and gradually to pale—it can signal slow healing. The color evolution of a healing wound is a visible marker of the wound's progression. When that progression stalls or deviates, it could be a sign of impeded healing.

Absence or Slow Development of Granulation Tissue

When recovering from a wound, forming granulation tissue—new tissue that develops during the healing process—is crucial. Granulation tissue typically appears as a thin, red layer covering the wound, facilitating wound closure. If this formation is absent or delayed substantially, it's an undeniable sign of slow wound healing.

Bear in mind the duration of the healing process can widely differ based on the specifics of the wound you've incurred. Numerous factors include the wound's severity, location, and health profile.

While it's natural for healing times to vary, alarm bells should ring if you observe a stark contrast between the healing progression of your current wound and previous injuries.

Furthermore, if the healing process substantially overshoots the timeframe initially projected by your healthcare provider, it should warrant a serious evaluation. Prolonged healing time could signal underlying complications or an inefficient healing process, yielding the necessity for a thorough medical assessment.

Factors Contributing to Slow Wound Healing

Thus, The essential question is, "What precipitates slow wound healing if you discern scant advancement in your recovery?"

Slow wound healing hinges on many factors, including numerous medical and lifestyle elements that can impact the wound healing speed. Unpacking these contributory factors is a valuable step toward procuring effective treatment and ensuring a smoother healing trajectory.

In the context of cutaneous wound healing, it is important to consider the potential cellular and/or molecular mechanisms involved, such as the role of stem cells. By understanding the molecular mechanisms underlying wound healing, healthcare professionals can develop targeted interventions to promote optimal healing.

Here are some common reasons for delayed wound healing:

Impaired Blood Circulation

The role of adequate blood circulation in wound care and healing cannot be overstated. Through blood flow, your body supplies oxygen, nutrients, and crucial immune cells, such as white blood cells, to the wound location, facilitating its healing.

However, medical conditions that curtail this blood flow, such as Peripheral Artery Disease (PAD), diabetes, kidney disease, obesity, high blood pressure, or vascular disease, can effectively slow down the healing trajectory. Additionally, impaired blood circulation, which can be caused by conditions like PAD or vascular disease, can lead to the development of pressure ulcers.

The wound care and healing process involves the influx of white blood cells, including bone marrow-derived endothelial progenitor cells (EPCs), to destroy microbes and other foreign bodies present in the wound area. Vascular endothelial growth factor plays a crucial role in this process by accelerating diabetic wound healing through increased angiogenesis and by mobilizing and recruiting bone marrow-derived cells.

In cases where the wound healing process is not progressing as expected, hyperbaric oxygen therapy can be utilized to promote healing by delivering high levels of oxygen to the wound site.

Diabetes Impact

Those with diabetes face unique challenges with wound healing. Impaired blood flow, compromised immune function, nerve damage, or neuropathy, all commonly associated with diabetes, can intervene to slow wound repair. Elevated blood glucose levels can also hamper cellular activity pivotal to the healing process.

Age-related Healing Delay

Our body's capacity to regenerate and repair tissues is declining as we age. Consequently, older adults may find their wounds, including skin wounds, heal more sluggishly than their younger counterparts.

Factors like reduced skin elasticity, diminished immune response, and often prolonged underlying health conditions play crucial roles in this delayed healing in the elderly.

Infections Hampering Wound Healing

An infection in a wound can dictate the pace of healing. Bacterial, viral, or fungal organisms can exacerbate and protract the inflammatory phase of wound healing, thereby obstructing the usual recovery timeline.

Recognizing and treating wound infections promptly ensures a smoother healing journey.

Impact of Chronic Diseases

Certain chronic conditions have been linked to intervening with the body's natural wound-healing capacity. Autoimmune disorders, inflammatory diseases, some types of cancer, and even persistent mental health conditions can deter the healing process, causing delays.

Medication-Related Delay in Healing

Particular medications can influence wound healing, too. Drugs like corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), immunosuppressants, and certain antiplatelets or anti-coagulants can dampen the immune response needed for healing and thus extend the healing timeline.

It's essential to confer with your healthcare provider about the potential side effects of your medications on wound recovery, including the presence of foreign materials that may interfere with the healing process.

In terms of the topical application of NSAIDs on the surfaces of chronic wounds, the local use of ibuprofen-foam provides moist wound healing, reduces persistent and temporary wound pain, and benefits chronic venous leg ulcer healing.

In some cases of traumatic injury, exploring a deep wound surgically may be necessary. Local anaesthetic will be given before the examination.

Smoking Effects on Healing

Smoking has been well-established as a factor that can hinder wound healing. It diminishes blood flow and oxygen delivery to tissues, obstructing healing.

Additionally, smoking heightens the risk of developing infections and impairs essential factors like skin elasticity and moisture, further hampering recovery.

Obesity and its Implications

An excess of body weight can contribute to poor blood circulation and ultimately impede the wound-healing process. Furthermore, obesity may exacerbate the risk of complications during healing, such as infection risk and wound dehiscence, due to stress on suture sites and altered skin barrier function.

Stress Impact on Healing

Chronic stress can be detrimental to wound repair, given its adverse effects on the immune system. Stress can cause disruptions in releasing hormones and other chemicals responsible for a proper immune response, potentially decelerating wound healing.

Wound Type and Location

The specific type and location of a wound can considerably affect the healing speed in the United States. Wounds in regions with less blood supply, notably in the lower extremities like feet or calves, may experience an extended healing timeline.

Deep wounds or those involving large muscle groups may also take a more leisurely pace when healing. Different types of wounds, such as cuts, can also impact the healing process.

Additionally, diabetic individuals in the United States are susceptible to developing chronic diabetic foot ulcers, a serious complication of diabetes which affects 15% of people with diabetes and accounts for 84% of all diabetes-related lower leg amputations.

The impaired healing abilities of diabetics with foot ulcers and/or acute wounds involve multiple pathophysiological mechanisms.

Nutritional Deficiencies and Healing

Adequate nutrition is indispensable for sound wound healing; nutritional deficiencies can significantly handicap the body's vital capabilities. Shortages in essential vitamins (such as vitamins C and A), minerals (like zinc and iron), and protein can limit the body's ability to regenerate tissues, repair damaged skin, and build new blood vessels, thereby delaying the healing process.

Nutrients like vitamin C, vitamin E, magnesium, copper, and boron also play significant roles in wound healing.

Boron and Its Role in Wound Healing

Boron is a trace mineral usually given much less attention than it deserves in nutritional science. It might not be classified as a "vital" nutrient for humans; however, its role in our bodies' overall functioning cannot be underestimated.

Though not a household name for essential nutrients, increasing research indicates that boron is gradually gaining importance.

For instance, its contributions to the process of wound healing have caught the eye of the scientific community. Notwithstanding its lack of superstar status in essential nutrients, boron holds a quiet yet potent significance in human health, meriting further exploration and understanding.

Potential Effects of Boron on Healing

The Impact of Boron on Collagen Formation

One of the widely suggested roles that boron plays in our bodies revolves around collagen formation. Collagen, a critical protein found in connective tissues, is elemental for providing strength and structure to the skin. Its production and maintenance are of utmost importance for effective wound healing.

As such, the potential contribution of boron in this process establishes it as a noteworthy element in maintaining skin health.

Involvement of Boron in Bone Health

Further underlining boron's contribution to overall wellness is its involvement in bone metabolism. Though its role might not be directly linked to wound healing, boron's potential contribution to bone health could indirectly influence the healing of bone fractures and other wound ailments related to the skeletal system.

This underpins boron's significance in maintaining robust bone health, increasing its relevance in nutritional science.

Boron's Potential Anti-inflammatory Effects

Interestingly, boron isn't just implicated in skin and bone health; it may also hold potential anti-inflammatory properties. While inflammation is integral to the wound-healing process in its early stages, excessive or prolonged inflammation may hinder it. This is where Boron might have a crucial role to play.

If boron carries anti-inflammatory properties, it could curb unnecessary inflammation, accelerating wound healing and aiding overall well-being.

Research on Boron's Influence on Wound Healing

In a notable study titled "Nothing Boring About Boron," researchers investigated the impact of applying a 3% boric acid solution (with boron as the primary active ingredient) to wounds.

What they found was remarkable: the recovery time for patients in intensive care was reduced by two-thirds. This noteworthy finding, backed by a credible source, provides substantial evidence for further exploration of the potential benefits of boron.

Conversely, in 2000, there was in vitro research using human fibroblasts showed that a similar solution as the first one just previously mentioned of boric-acid improved wound healing through action on the extracellular matrix.

There were further in vitro studies published later on, 2 years later, in which revealed that the benefits of the boron were due to direct actions on specific enzymes found in fibroblasts: elastase, trypsin-like enzymes, collagenase, and alkaline phosphatase.

They state “...boron enhanced the trypsin-like, collagenase, and cathepsin D activities in fibroblasts…it did enhance phosphorylation, it can be hypothesized that boron may affect living cells via a mediator, which could be TNFalpha whose transduction signal involves a cascade of phosphorylations.”

Additional Benefits of Boron

Bone Health

Research suggests that boron may play an influential role in bone metabolism and maintaining bone density. Some studies indicate an intriguing possibility that boron might enhance the absorption of calcium and magnesium, crucial minerals for bone health.

This aspect of boron could be particularly beneficial for postmenopausal women as boron is conjectured to positively affect bone mineral density, potentially offsetting age-related bone loss.

Joint Health

Boron's benefits extend to joint health. It's believed to contribute to the metabolism of key nutrients associated with joint function and might play a preventative role against conditions like osteoarthritis.

Thus, boron's relationship with joint health magnifies its importance in the nutritional landscape.

Cognitive Function

Boron's possible influences also encompass cognitive function. Certain studies suggest that boron could exhibit neuroprotective effects and boost cognitive performance. However, the breadth and depth of boron's impact on mental health remain to be fully explored, indicating a need for further research.

Hormonal Balance

Scientific inquiries have also delved into the potential impact of boron on hormone metabolism. Emerging evidence proposes that boron might regulate specific hormones like vitamin D, testosterone, and estrogen. If accurate, this implication could significantly impact reproductive health and prevent conditions like osteoporosis.

Inflammation and Immune Function

Further investigations into boron reveal its potential anti-inflammatory properties, suggesting a possible role in overall immune function.

Again, the extent of this property's influence is yet to be wholly understood, emphasizing the need for additional research in this promising area.


In conclusion, slow wound healing can indicate several underlying health conditions, with one such possibility being a deficiency in the trace mineral boron.

Our exploration into the various roles of boron in the human body has illuminated its potential contributions in many health areas, ranging from bone and joint health, cognitive function, and hormonal balance to counteracting inflammation. Importantly, studies have highlighted boron's possible influence on wound healing, mainly through collagen formation, bone health, and anti-inflammatory effects.

While more research is needed to understand these connections fully, it is clear that boron has a considerable impact on our health.

Therefore, if you experience slow wound healing and have pondered its potential reasons, considering boron's role and ensuring its adequate intake might be a wise step on your journey to optimal health.
