Introduction
Imagine a world where chronic wounds that refuse to heal and painful digestive ulcers could be treated with a natural remedy that has been used in traditional medicine for centuries. This isn't a futuristic fantasy—it's the promising reality being uncovered by scientists studying Dipteracanthus patulus (Jacq), a modest-looking plant with extraordinary healing properties.
As modern medicine grapples with the limitations of conventional treatments, including antibiotic resistance and unwanted side effects, researchers are turning their attention back to nature's pharmacy, validating traditional wisdom with rigorous science.
This article explores the exciting scientific journey of how leaf extracts from this remarkable plant are revealing their potent abilities to combat ulcers and accelerate wound healing, offering new hope for millions suffering from these debilitating conditions.
The Double Burden: Ulcers and Chronic Wounds
Peptic ulcer disease (PUD) affects approximately 10% of the global population, creating sores or lesions in the gastrointestinal mucosa that extend throughout the muscular mucosa 2 3 .
These ulcers develop from an imbalance between aggressive factors like gastric acid, pepsin, and Helicobacter pylori infection, and the protective mechanisms of our stomach lining, including mucus secretion, adequate blood flow, and prostaglandins 3 .
The most common symptom is a gnawing or burning epigastric pain that often occurs after meals. While conventional treatments like proton pump inhibitors and antimicrobial agents exist, they carry risks of treatment failure, relapse, and various side effects including gastrointestinal infections and drug interactions 2 .
Chronic wounds represent a different but equally significant healthcare challenge worldwide. Unlike acute wounds that follow an orderly healing process, chronic wounds fail to progress through the normal stages of healing within an expected timeframe 5 .
The healing process typically involves four overlapping phases:
1. Hemostasis
Immediate blood clotting to prevent bleeding
2. Inflammation
White blood cells combat infection (4-6 days)
3. Proliferation
Rebuilding with new skin cells and collagen (4-24 days)
4. Maturation
Strengthening of new skin tissue (21 days to 2 years) 5
Chronic wounds often stall in the inflammatory phase due to factors like persistent infection, poor blood flow, or underlying conditions such as diabetes, creating a significant burden on healthcare systems and drastically reducing patients' quality of life 6 .
Dipteracanthus Patulus: A Botanical Powerhouse
Dipteracanthus patulus (also known as Ruellia patula) is an erect, pubescent shrub that grows up to 50 cm tall, with elliptic ovate leaves and glabrous fruit capsules containing 8-10 seeds 4 .
Distributed across Arabia, India, Pakistan, Africa, and Sri Lanka, this plant has been used for generations in traditional medicine to treat cuts, wounds, eyesores, and even snakebites 4 7 .
In Southern India, traditional healers have specifically used the leaves to promote wound healing, while other parts of the plant have been employed to address conditions ranging from gonorrhea to renal infections 4 .
This rich history of ethnobotanical use provided the initial clues that prompted scientists to investigate its therapeutic potential through modern pharmacological approaches.
Phytochemical Treasure Trove
The medicinal properties of D. patulus stem from its rich composition of bioactive phytochemicals. Research has identified several key compounds responsible for its therapeutic effects:
-
β-carotene and β-sitosterolMajor compounds
- Phenolic compounds
- Flavonoids
- Iridoid glycosides, tannins, and alkaloids
Phytochemical Quantities

| Total Phenolic Content | Acetone | 142.94±1.01 mg GAE/g | Antioxidant and anti-inflammatory effects |
| Total Phenolic Content | Methanol | 104.41±7.06 mg GAE/g | Antioxidant and anti-inflammatory effects |
| Total Flavonoid Content | Acetone | 37.49±1.83 mg QE/g | Free radical scavenging |
| Total Flavonoid Content | Methanol | 26.73±10.65 mg QE/g | Free radical scavenging |
| β-carotene | Methanol | Identified via HPTLC | Antimicrobial and antioxidant |
| β-sitosterol | Methanol | Identified via HPTLC | Anti-inflammatory and wound healing |
The Healing Potential: Scientific Evidence
While direct studies on D. patulus for ulcer treatment are still emerging, its closely related species and phytochemical profile suggest multiple protective mechanisms. The plant's bioactive compounds likely work through:
Cytoprotective Action
Strengthening the gastric mucosal barrier
Antioxidant Activity
Neutralizing reactive oxygen species
Anti-inflammatory Effects
Reducing pro-inflammatory cytokines
Antimicrobial Action
Potentially inhibiting H. pylori growth
Multiple studies have confirmed the remarkable wound healing capabilities of D. patulus leaf extracts:
Antimicrobial Protection
Research has demonstrated that acetone extracts show significant activity against common wound pathogens including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa 4 .
Anti-inflammatory Action
The protein denaturation inhibition assay revealed potent anti-inflammatory properties in leaf extracts, particularly in the acetone fraction 4 .
Antioxidant Defense
Through multiple in vitro methods including DPPH, hydrogen peroxide, and nitric oxide radical scavenging assays, methanolic extracts have shown impressive free radical neutralizing capacity 7 .
Comparative Efficacy of Different Extracts
A Key Experiment: Visualizing Healing Through the Chick Embryo Wound Model
One of the most visually compelling studies investigating the wound healing potential of D. patulus utilized the chick embryo chorioallantoic membrane (CAM) model . This innovative approach allowed researchers to directly observe the plant's effect on the critical process of angiogenesis—the formation of new blood vessels that is essential for wound healing.
The experimental procedure followed these key steps:
- Plant Material Preparation: Fresh leaves were collected, shade-dried, and powdered
- Extraction Process: Using ethanol and chloroform solvents
- Solution Preparation: Concentrated and diluted to 500μg/ml concentration
- CAM Assay: Applied to chick embryo membranes
- Blood Vessel Quantification: Meticulous counting of blood vessels
The findings from this experiment provided striking visual evidence of D. patulus's wound healing capabilities. Both the ethanolic and chloroform extracts, along with the positive control, promoted a significant increase in the number of blood vessels compared to the saline-treated negative control .
Most notably, the group treated with 500μg/ml of ethanolic extract demonstrated enhanced formation of new blood vessels, visually confirming the pro-angiogenic effect of the plant's bioactive compounds. When comparing the two extraction methods, the ethanolic extract showed superior activity to the chloroform extract, suggesting that the polar compounds extracted by ethanol possess stronger angiogenic properties .
| Treatment Group | Concentration | Blood Vessel Formation | Comparative Efficacy |
|---|---|---|---|
| Negative Control (Saline) | - | Baseline | Reference |
| Positive Control (Diclofenac sodium) | 50μg/ml | Increased | Effective |
| D. patulus Chloroform Extract | 500μg/ml | Increased | Moderate |
| D. patulus Ethanolic Extract | 500μg/ml | Significantly Increased | Most Effective |
This research demonstrates that D. patulus leaf extracts stimulate angiogenesis, providing a scientific explanation for its traditional use in wound care. By promoting the development of new blood vessels, the plant extract enhances blood flow to wounded areas, delivering essential oxygen and nutrients while removing waste products—all critical factors for accelerated tissue repair.
