This study will test a special powder for ulcers caused by a variety of conditions such as pressure that sometimes happen when a person is at the end of life. The powder will be applied to these ulcers to see if it helps with pain, odor and drainage (leakage). People who are being cared for by hospice or palliative care organizations will be invited to be in the study. The study will also find out if the powder is easy to use by caregivers as well as improving the comfort and quality of life of the person who has the ulcer.
