Sweet basil has been used for thousands of years as a culinary and medicinal herb. It acts principally on the digestive and nervous systems, easing flatulence, stomach cramps, colic and indigestion.
The leaves and flowering tops are antispasmodic, aromatic, carminative, digestive, galactagogue, stomachic and tonic.
They are taken internally in the treatment of feverish illnesses (especially colds and influenza), poor digestion, nausea, abdominal cramps, gastro-enteritis, migraine, insomnia, depression and exhaustion.
Externally, they are used to treat acne, loss of smell, insect stings, snake bites and skin infections.
The leaves can be harvested throughout the growing season and are used fresh or dried.
The mucilaginous seed is given in infusion in the treatment of gonorrhoea, dysentery and chronic diarrhoea.
It is said to remove film and opacity from the eyes.
The root is used in the treatment of bowel complaints in children.
Extracts from the plant are bactericidal and are also effective against internal parasites.
The essential oil is used in aromatherapy. Its keyword is ‘Clearing’.
