Background and study aims
Wounds and ulcers are a major issue for health care systems and for individuals.
The convention treatment (CT) is applying a tulle dressing over wound/ulcers on a weekly basis. As a result 80% of type-1 or type-2 wound/ulcers heal in six weeks.
Matico (Buddleja globosa H.) is a shrub from Chile recognized by the Chilean Government Health Care System as a medicinal plant that can help heal wounds and ulcers. There has been no previous studies to demonstrate its therapeutic efficacy and safety for external and internal lesions. If matico is a medicinal plant with healing properties, we expect a 30% improvement in the healing process, a significant reduction in cost, and the same or less adverse reaction compared to CT alone and an improved quality of life. The aim of this study is to assess how well an extract of matico works on type-1 or type-2 wound/ulcers.

Who can participate?
Men and women aged between 18 and 75, with type-1 or -2 wounds/ulcers, and body mass index between 20 and 35.

What does the study involve?
Participants are randomly allocated to receive conventional treatment (CT) or CT + matico cream.

What are the possible benefits and risks of participating?
The healing process is faster and cheaper.

Where is the study run from?
Primary Care Centre, Santiago, Chile

When is the study starting and how long is it expected to run for?
The study is expected to start in August 2013 and to recruit participants for one year.

Who is funding the study?
This study is fully funding by the National Commission for Scientific and Technological Research (CONICYT) through its National Fund for Research and Development in Health (FONIS) program (Chile).

Who is the main contact?
