Lemon and Health benefits

Some sources state that lemons contain unique flavonoid compounds that have antioxidant and anti-cancer properties. These may be able to deter cell growth in cancers. Limonins found in lemons could also be anti-carcinogens.
Because of its high Vitamin C content, lemon has been touted in alternative medicine as a tonic for the digestive system, immune system, and skin. There is a belief in Ayurvedic medicine that a cup of hot water with lemon juice in it tonifies and purifies the liver. In a Japanese study into the effects of aromatherapy, lemon essential oil in vapour form has been found to reduce stress in mice.
