Lemons are an excellent preventative medicine and have a wide range of uses in the domestic medicine chest. The fruit is rich in vitamin C which helps the body to fight off infections and also to prevent or treat scurvy[4, 240, 254]. It was at one time a legal requirement that sailors should be given an ounce of lemon each day in order to prevent scurvy[4]. Applied locally, the juice is a good astringent and is used as a gargle for sore throats etc[4]. Lemon juice is also a very effective bactericide[7]. It is also a good antiperiodic and has been used as a substitute for quinine in treating malaria and other fevers[4]. Although the fruit is very acid, once eaten it has an alkalizing effect upon the body[254]. This makes it useful in the treatment of rheumatic conditions[254]. The skin of the ripe fruit is carminative and stomachic[240]. The essential oil from the skin of the fruit is strongly rubefacient and when taken internally in small doses has stimulating and carminative properties[4]. The stem bark is bitter, stomachic and tonic[218]. An essential oil from the fruit rind is used in aromatherapy. Its keyword is 'Refreshing'[210]. Citrus species contain a wide range of active ingredients and research is still underway in finding uses for them. They are rich in vitamin C, bioflavonoids, acids and volatile oils. They also contain coumarins such as bergapten which sensitizes the skin to sunlight. Bergapten is sometimes added to tanning preparations since it promotes pigmentation in the skin, though it can cause dermatitis or allergic responses in some people[238]. Some of the plants more recent applications are as sources of anti-oxidants and chemical exfoliants in specialized cosmetics[238]. The bioflavonoids in the fruit help to strengthen the inner lining of blood vessels, especially veins and capillaries, and help counter varicose veins and easy bruising[254].
