Spinach Extract: A Promising Treatment for Diabetic Wounds
Spinach, known for its vibrant green leaves and nutrient-rich profile, has long been hailed as a superfood. Its health benefits extend beyond the prevention of chronic diseases. A recent study has revealed that spinach extract could play a role in promoting the healing of diabetic ulcers, bringing hope to the millions of people affected by this condition.
Chronic diabetic ulcers are a significant problem for individuals with diabetes, often persisting for months or even years. Approximately 15% of people with diabetes experience lower-extremity ulcers that fail to heal, and this can eventually lead to amputation. These ulcers affect roughly 6.3% of the global population.
In the study published in Scientific Reports, researchers found that spinach extract not only improved the healing of diabetic wounds but also facilitated weight loss, which is particularly beneficial for individuals with diabetes who often struggle with overweight conditions.
The study investigated the efficacy of two types of spinach extract: one water-based (aquatic) and the other alcohol-based. Both extracts were found to promote wound healing, with the alcohol-based extract showing a slightly better performance.
The study involved 72 adult rats, divided into six groups. These groups included rats with and without diabetes, each receiving different types of spinach extracts. The most significant wound recovery was observed in the groups of rats that received spinach extract for two months, both before and after the induction of diabetes mellitus.

The researchers assessed wound healing by measuring various factors, including VEGF, blood sugar levels, and weight loss. While the differences in some measures of wound healing were not significant at the end of the study period, as healing had occurred in all groups, the observations highlighted the potential benefits of spinach extract.
To understand why wounds heal slower in individuals with diabetes, it is crucial to grasp the role of several factors. When a wound occurs, red blood cells, proteins, nutrients, and oxygen-bound red blood cells are sent to promote clotting and healing. However, high blood sugar levels in diabetes can lead to stiffened blood vessels, which slow down circulation and reduce oxygen supply to the tissues. This impairs the function of white blood cells and increases the risk of infection. Additionally, peripheral neuropathy in diabetes can cause a reduced sense of pain, leading to untreated wounds that may become chronic, especially in areas prone to minor injuries, such as the lower limbs.
Spinach emerges as a promising therapeutic ingredient due to its unique attributes. The vegetable is rich in vitamins, antioxidants, glutamine, and zinc, all of which contribute to wound healing. Spinach contains phenolic compounds like lutein, lycopene, and linolenic acid known for their protective effects against oxidative damage. Vitamins C, E, K, and phytochemicals found in spinach play a crucial role in collagen formation, cellular growth, and blood-vessel density. The presence of glutamine in spinach is particularly significant, as it serves as a precursor for arginine, an amino acid heavily involved in wound-healing processes. Additionally, zinc, found in spinach, contributes to protein development, including collagen synthesis.
While the study primarily focused on diabetic wounds, spinach extract’s nutritional properties and antioxidant capacity can potentially benefit non-diabetic patients as well. The study suggested that prophylactic intake of spinach extract may have a place in preventing wounds, particularly for individuals at risk and those with diabetes. However, it is important to note that further research is needed, including studies involving human subjects and a diverse range of backgrounds.
Registered dietitian nutritionists emphasize that maintaining normal blood sugar levels is crucial for promoting normal wound healing, as the body already possesses inherent processes for this purpose. Spinach extract, if validated in human studies, could be a beneficial adjunct to wound healing therapy for individuals with diabetes. However, it is essential to approach its translation to human use with caution.
Spinach, the humble leafy green, may hold the key to improving the lives of those affected by diabetic wounds. Its potential as a therapeutic ingredient offers hope for better wound healing outcomes and a brighter future for individuals with diabetes. As research in this field continues to evolve, spinach extract might just prove to be a game-changer in wound care.
