Abstract

This invention relates to a pharmaceutical preparation for the treatment of compromised tissue such as skin wounds and ulcers in humans and animals and a method of preparation. This is a multifunctional natural matrix meant for the treatment of compromised tissues which also relates to the anti-cancer transdermal patch for melanoma therapy. Further, the invention comprises for the treatment of Alzheimer's, and multiple sclerosis also. The composition consists of water-solubilized nano-sized formulation of non-aqueous solvent extract of phytopharmaceuticals in herbal, animal or synthetic biocompatible gel or on matrix coated or both. The composition is used as a topical device for the treatment of compromised tissues in its preferred embodiment.

Claims (15)

1. A flexible, biocompatible bandage dressing comprising:

a biocompatible, porous matrix; and

a plurality of dried layers of phytopharmaceutical formulation on the biocompatible, porous matrix, wherein each dried layer of phytopharmaceutical formulation has a thickness of about 10 μm to 100 μm, wherein each dried layer of phytopharmaceutical formulation comprises 0.5 to 20 percent of physico-chemical treated, water soluble, nano-extract of the plant Emblica officinalis, 1.0 to 20 percent of physico-chemical treated, water soluble, nano-extract of the plant Camellia sinsensis, 0.1 to 12 percent of physico-chemical treated, water soluble, nano-extract of curcumin, and 0.2 to 12.0 percent of aloe vera gel.

2. The flexible, biocompatible bandage dressing of claim 1 , wherein said aloe vera gel comprises 0.5 to 9.0 percent tocopherol.

3. The flexible, biocompatible bandage dressing of claim 1 , wherein said aloe vera gel is derived from a 0.5 to 3.0 percent aloe vera solution and 1.0 to 10.0 percent nano-silver solution.

4. The flexible, biocompatible bandage dressing of claim 1 , comprising liposomes that encapsulate at least a portion of said phytopharmaceutical formulation, said liposomes having a diameter of about 0.3 to 500 nanometers.
