How does Wine work?
Wine contains ethanol (alcohol), which blocks various nerve pathways in the brain. It also contains chemicals that might have beneficial effects on the heart and blood circulation such as antioxidant effects, and preventing blood platelets from forming clots.
Are there safety concerns?
Wine is likely safe for most adults when no more than 2 five-ounce glasses are drunk per day. Avoid higher amounts. Larger amounts can cause flushing, confusion, blackouts, trouble walking, seizures, vomiting, diarrhea
, and other serious problems.
Long-term use of large amounts of wine causes many serious health problems including dependence, mental problems, heart problems, liver problems, pancreas problems, and certain types of cancer.
