Introduction

The induction of bacterial growth, in the experimental design used, was proposed as a strategy for evaluating the regeneration of epithelial tissue through the production of extracellular matrix by the fibroblast, collaborating with the healing process, in addition to inducing the production of glycocalyx in epithelial cells, facilitating adhesion and migration to recover the injured region.

Aim

To determine the action of the tinctures of Hamamelis virginiana, Maytenus ilicifolia and Casearia sylvestris on the growth of Escherichia coli cultures, to simulate, in this type of model, the potential regenerative activity of connective and epithelial cells, especially the fibroblast, by means of the disk-diffusion and spectrophotometric.

Results

The tinctures of Hamamelis virginiana, Maytenus ilicifolia and Casearia sylvestris at high and medium concentrations (above 1.6%) inhibit the development of Escherichia coli in culture, but at low concentrations (from 0.4 to 1.6%) induce bacterial proliferation, especially in the case of Maytenus ilicifolia and Casearia sylvestris tinctures.
