Were our Ancestors Right in Using Flax Dressings? Research on the Properties of Flax Fibre and Its Usefulness in Wound Healing

The level of ROS in NHDF cells cultured for 48 h with the presence of the tested flax fibres in four different weights (10, 20, 30, and 40mg): (a) subsequently exposed to H2O2 (100 μM, 30 min, 4°C); (b) not exposed to H2O2. The results are presented as -fold–ratio to control culture (cells without fibres; ). The results are the means of 5 independent . The statistical significance of differences between the results for the tested flax fibres compared to the control was calculated using Tukey’s post hoc test (𝑝 < 0.05).
