Wound coverage by the linen dressing accelerates ulcer healing

Area of Science:

• Biomaterials Science
• Wound Healing Research
• Plant-Based Therapeutics

Background:

• Chronic ulcers represent a significant global health challenge, with increasing incidence due to aging populations and comorbidities.
• Effective wound management requires addressing key factors: cleansing, bacterial control, exudate management, and maintaining a suitable local tissue environment.

Purpose of the Study:

• To develop and evaluate an innovative interactive wound dressing utilizing natural flax (Linum usitatissimum) raw materials.
• To assess the dressing's efficacy in managing the chronic wound microenvironment and promoting healing.

Main Methods:

• Flax seedcakes, oil, and fiber were processed to create the interactive dressing.
• Chromatographic techniques were employed to analyze bioactive compound content.
• In vitro studies on human dermal fibroblast cell cultures (NHDF) assessed biological activity.
• Clinical trials were conducted to evaluate the dressing's performance in patients with chronic leg ulcers.

Main Results:

• The flax dressing effectively managed wound exudate through its hydrophilic fiber component, controlling flow and microenvironment.
• The dressing accelerated the healing cascade by delivering lignocellulose fiber rich in phenolic compounds, sterols, cannabidiol, unsaturated fatty acids, and 3-hydroxybutyrate polymer.
• Pre-clinical data demonstrated a notable reduction in wound size in patients with chronic leg ulcers.

Conclusions:

• This study reports the first successful application of an innovative, interactive linen dressing for chronic wound treatment.
• The flax-based dressing offers a promising natural alternative for managing chronic wounds, promoting faster healing and improving patient outcomes.
