I did some research..
Aqua regia is a mixture of one part nitric acid and three parts hydrocloric acid --- VERY bad for you =/
Adding gold makes it form another toxic compound: gold cloride. While not as toxic as drinking strait nitric and hydrocloric acid it is pritty toxic. Heres what I found on it.
Swallowed: Irritation, anusea and diarrhea. may cause stomatitis, metallic tasete.
Eye: Irritation. Exposure to high concentration of hydrogen chloride ghas may cause blindness. Gold deposits may occur in the eyes causing keratitis and corneal ulceration.
Skin: Causes burns. Exposure can cause itching, erythema, eczema, erthema multiforime.... blah blah ...Exposure can also cause grey to plue pigmintation... etc.
Inhaled: Material is extremely destructive to the tissure of mucous membranes and upper respitory tract... etc etc. Need I continue?
I don't see how adding wine will do anything to the gold cloride. I wouldn't drink that even if it did give phychic powers (It doesn't though). =/
