Honey based wound dressing
The present invention is directed to the use of honey in medical dressings. Preferred embodiments modify honey with a viscosity increasing agent, resulting in a range of possible compositions including ointments and salves, self-adhesive gels such as for use on mouth ulcers and pustules, and pliable or flexible sheets which can be used as a wound covering. Preferred viscosity increasing agents include both particulate and continuous gels, respective examples of each including agars and alginates. Selected honeys preferably, but not necessarily, exhibit antibacterial properties other than what is merely conferred by osmolarity and sugar concentration effects.
1. A formable or pliable, or both, composition for dressing wounds, comprising a combination of a medicinal amount of at least one honey and at least one gelling compound, wherein the amount of the gelling compound in the composition is sufficient to cause the composition to be a formable or pliable, or both, solid that is mouldable to fit a wound to which the composition is applied, and wherein at least 50% by weight of the composition is said at least one honey.
2. The composition of claim 1 , wherein the at least one gelling compound is an alginate-based material.
3. The composition of claim 1 , wherein the at least one gelling compound is a natural-based gelling compound.
4. The composition of claim 1 , further comprising a gelling compound in the form of a continuous gel.
5. The composition of claim 1 , wherein the at least one gelling compound causes said composition to be in the form of a particulate gel.
6. The composition of claim 1 , which is substantially non-running at a temperature at least as high as body temperature.
7. The composition of claim 6 , which is substantially non-running at about 45° C.
8. The composition of claim 1 , further comprising at least one moisture absorbing, trapping, or removing compound suitable for removing aqueous exudate from a wound, and wherein the amount and nature of said exudate removing compound is such that the composition remains substantially non-running for an extended period of time after application to a wound when compared to a similar composition in which the said water trapping, removing or absorbing compound is absent.
9. The composition of claim 1 , which has the property of absorbing bodily fluid over a period of time not less than about the time required for the wound to heal.
10. The compound of claim 9 , which is suitable for internal use.
11. The composition of claim 1 , having a viscosity that is sufficient to render the composition extrudable to fill wound cavities.
12. The composition of claim 1 , which is a medicinal composition in solid plastic form.
13. The composition of claim 1 , in the form of a flexible sheet.
14. The composition of claim 13 , comprising a combination of gelling compounds.
15. The composition of claim 13 , comprising at least one gelling compound that is formable into a continuous gel, and at least one gelling compound that is formable into a particulate gel.
16. The composition of claim 1 , further comprising at least one of a pigment or sulphur.
17. The composition of claim 16 , which comprises a pigment and said pigment is flesh-colored.
18. The composition of claim 1 , wherein said at least one honey has antimicrobial or bacteriostatic properties.
19. The composition of claim 18 , wherein said at least one honey comprises a non-peroxide anti-microbial or bacteriostatic component.
20. The composition of claim 1 , which is sterilized against clostridial spores by irradiation.
21. A wound dressing, comprising the composition of claim 1 .
22. The wound dressing of claim 21 , further comprising a reinforcing material.
23. The wound dressing of claim 22 , wherein the reinforcing material is selected from the group consisting of gauze, mesh, random fibers and woven fabric.
24. The wound dressing of claim 22 , wherein the reinforcing material is embedded in the composition.
25. A modified wound dressing, comprising the wound dressing of claim 22 , applied to a backing sheet.
26. The modified wound dressing of claim 25 , wherein backing sheet comprises at least one layer.
27. The modified wound dressing of claim 25 , wherein the backing sheet comprises adhesive areas other than in areas coextensive with the wound, thereby allowing the modified wound dressing to be applied and adhere to unwounded skin or other application surface.
28. The modified wound dressing of claim 25 , comprising a backing sheet on which is present a wound patch, and in which said composition is present.
29. The modified wound dressing of claim 28 , wherein said wound patch comprises a plurality of localized regions comprising said composition distributed within a larger area of said backing sheet.
30. A method of treating acne, comprising applying the wound dressing of claim 25 thereto.
31. A method of treating a pustule, comprising applying the wound dressing of claim 25 thereto.
