Since ancient times wine was used as a medicine both physically and mentally. Hippocrates, (think the Hippocratic Oath) , that every physician takes, to not cause harm to their patients, recommended that everyone have a glass of wine every day for a healthy well balanced diet. The Roman physician, Galen, would treat gladiators using wine as a disinfectant for their wounds. Over four years he treated many gladiators and only four died, Sixty gladiators died at the hands of physicians before him.
In the bible wine was used as a disinfectant to clean wounds. (Luke 10:34) In the story of the Good Samaritan, wine was poured into the wounds of the man found bleeding and dying on the side of the road. As a pain reliever, Jesus was offered wine while on the cross. In Proverb 31:6, "Give strong drink to him that is ready to perish and wine unto those that be of heavy heart." In (Tim 5:23) wine was used to purify water, Paul told Timothy to use no longer water, but to use wine for his stomachs sake.
During Medieval times the Catholic Monasteries would use wine for their Medical treatments. Islam restricted the use and consumption of alcohol, wine was still used for a lot of health reasons, such as digestive health and disinfecting wounds.
In modern times of course, you no longer need wine for disinfecting and purifying water. Wine is still good for digestive health and the relief of pain, and just general well being, of course wine also tastes good. Much illness is caused by stress and processed foods. Wine is still very important as a medicine.
I also make an onion wine. Not for drinking, for cooking. You get a double whammy with onion wine. The alcohol ( over 6 % will kill botulism, a bacteria that is common in many foods). Onions were used in Chinese medicine for angina, cough, bacterial infection, and breathing problems. In modern times studies have shown antibiotic, anti-inflammatory, and diuretic benefits. Onions are also high in flavinoids, shown to protect against cardiovascular diseases. Not recommended for people with sulphur allergies
