The work analyzes the global experience of using wines and grape-processing products to support a person’s physical, mental, and psychological health, to slow down aging, to prevent and treat many diseases, in particular cardiovascular and oncological ones, endocrine system disorders, etc. It has been shown that a great deal of waste, including marc, is obtained while processing grapes and producing wine. The fact has been pointed out that in Ukraine, the technologies of using wine-making waste in food and cosmetic industries and in medicine are being developed and introduced but slowly, though the level of viticulture is high. The importance and prospects of finding ways to process grape marc have been proved, as its valuable chemical composition allows obtaining dietary supplements and oenotherapeutic products for spa and wellness industry. The following rational parameters have been suggested to extract the most valuable biologically active substances (polyphenols) from grape marc: microwave extraction; specific power of the microwave installation 1.6–1.7 kW/kg; 40% ethyl alcohol as the extractant; proportion of water (hydromodulus) 1:5; extraction temperature 60–65°C; 4 heating stages; stage interval 1.5–2 minutes; total extraction time 12–14 minutes. The physico-chemical parameters of the marc extracts obtained from the grapes harvested in 2016 and 2017 have been determined. It has been established that, besides polyphenols, a whole complex of biologically active substances is extracted. It has been shown that grape marc can be used to produce dietary fibre, pectins, and other valuable substances. The medical and biological properties of the polyphenolic complex obtained from marc (the Odesky Chorny variety of grapes) have been studied on laboratory rats to determine its antioxidant activity and the prospects of its use in treating type 2 diabetes. The protective properties of the obtained product have been proved. Such processes have been established to take place as the mobilization of the antioxidant system of cells, the normalization of the enzyme activity of the antioxidant protection system, and a decrease in the level of markers of oxidative modification of proteins and lipids (that are higher than normal with diabetes mellitus). It has been suggested to use polyphenolic complex extracts in oenotherapy as a skin and face care product with protective properties.
