Heart disease patients can drink honey water, but it can only be used for flavoring purposes and has minimal effect on health care, so heart disease patients should not rely on honey water to treat heart disease or regulate the body. It is best to keep the water temperature below 60°C to avoid damaging the proteins or active ingredients. Do not overdo it when drinking honey water. Some patients with heart disease and if diabetes is present, try not to drink it because excessive honey water may cause a rapid rise in blood sugar.
