NOVELTY - Solubilizing and stabilizing curcumin in aqueous solution comprises: (a) providing quantity of water; (b) providing over 0.008 mg curcumin per ml water; (c) optionally providing at least 0.01 ml lower alcohol per ml of water; (d) optionally providing at least 0.01 ml polyalkyleneoxide (PAO) per ml of water; (e) combining water, curcumin and optional lower alcohol in any order and optionally with mixing; and (f) heating combined water, curcumin and optional lower alcohol to temperature in excess of 100%, optionally at pressure exceeding 1 atmosphere.    USE - The process is useful for solubilizing and stabilizing curcumin in aqueous solution which is used: in a product, where the product includes food product, supplement product, pharmaceutical product, beverage, condiment, coloring, glaze, spice, herbal mixture, liquid nutraceutical supplement, gel or capsule (all claimed); for treating, preventing or ameliorating medical or psychological condition in subject (the subject is humans, pets e.g. dogs, cats, rodents, birds, reptiles, amphibians and fish, livestock e.g. cattle, horses, sheep, goats, alpaca, chickens, geese and pigs, research animals e.g. mice, rats, pigeons, dogs, cats, captive woodland creatures, captive aquatic creatures, captive birds, captive desert creatures and captive marsh creatures or display animals e.g. zoo animals, carnival display animals and commercial aquarium animals)), the subject has medical condition that require antioxidative, antiinflammatory, antiviral, antibacterial and/or antifungal effect, the medical condition is autoimmune diseases, multiple sclerosis, rheumatoid arthritis, psoriasis, inflammatory bowel disease, Sjogren's syndrome, systemic lupus erythematosus, type I diabetes mellitus, neurodegenerative diseases or type of cancer, type II diabetes, asthma, allergies, cataracts, atherosclerosis, Alzheimer's disease, Parkinson's disease, myelodysplastic syndromes, cystic fibrosis, myocardial infarctions, high cholesterol, stroke, malaria, HIV, herpes simplex virus (HSV-1) or psoriasis, and the subject has a psychological condition that requires mood elevation and the psychological conditional includes clinical depression, bereavement, mentally depressing physical pain, dementia, battlefield stress, academic stress, occupational stress, relational stress, homesickness or other loneliness (all claimed). Test details are described but no results given.    DETAILED DESCRIPTION - Solubilizing and stabilizing curcumin in an aqueous solution comprises: (a) providing a quantity of water; (b) providing over 0.008 mg curcumin per ml water; (c) optionally providing at least 0.01 ml lower alcohol per ml of water; (d) optionally providing at least 0.01 ml polyalkyleneoxide (PAO) per ml of water; (e) combining the water, curcumin and optional lower alcohol in any order and optionally with mixing; and (f) heating the combined water, curcumin and optional lower alcohol to a temperature in excess of 100%, optionally at a pressure exceeding 1 atmosphere, where steps (a), (b) and (c) may be done in any order, and the process includes at least one of combining the lower alcohol or optional polyalkyleneoxide in step (e) and applying a pressure exceeding 1 atmosphere in step (f). INDEPENDENT CLAIMS are also included for:    (1) a product comprising the solubilized and stabilized curcumin in aqueous solution made by the process;    (2) treating, preventing or ameliorating a medical or psychological condition comprising administering to a subject the aqueous solution comprising over 0.008 mg curcumin per ml water; and    (3) staining (I) proteins comprising providing a solution of curcumin that has been solubilized by heating in water, optionally under pressure and optionally in the presence of lower alcohol or polyalkyleneoxide, combining the solubilized curcumin with at least one protein in an assay for an amount of time sufficient to stain the protein, and quantifying an amount of protein as a function of the amount of fluorescence or colorimetric value of the stained protein.
