Pressure sores - 1 on each hip

One thing that may bring some relief and prevent further pressure sores from developing is to use an egg crate foam mattress directly under the patient. I used this with one of my patients who had developed bed sores on her ankles. Can purchase off of Amazon.
Also, to give the sores a chance to heal, I applied a healing liniment like comfrey and gently covered it with a soft covering. That way the tissue is being protected from further abrasion. The egg crate foam mattress was the major factor in healing her sores. I found that with daily care the wounds were able to heal.

While it certainly has been used over very long periods of time for a range of ailments there is only one published case study that I could find of its efficacy for bed sores particularly.

While you should never take anything from wikipedia at face value, the following is of note:

" Locals of Moomy city on Socotra island use the Dracaena resin as a sort of cure-all, using it for such things as general wound healing, a coagulant (though this is ill-advised with commercial products, as the Daemonorops species acts as an anti-coagulant[6] and it is usually unknown what species the dragon’s blood came from), curing diarrhea, lowering fevers, dysentery diseases, taken internally for ulcers in the mouth, throat, intestines and stomach, as well as an antiviral for respiratory viruses, stomach viruses and for skin disorders such as eczema. It was also used in medieval ritual magic and alchemy."
