Constituents

The leaves are rich in the volatile oils ascaridole, cineole and camphor which gives it its distinctive aroma. Both leaves and bark contain flavonoids - cancer-fighting antioxidants; and various alkaloids, the main one being boldine.

Medicinal uses

Boldo is widely used in herbal medicine to treat gallstones and for various liver, stomach and digestive disorders. The active constituent, boldine, stimulates bile secretion and reduces gall-bladder inflammation.

Boldo has a soothing effect on the lining of the bladder, and antiseptic properties, and so can help cystitis sufferers. In Chile the herb has long been utilised as a cure for syphilis and gonorrhoea and is also used to get rid of parasitic worms. In Brazil, the herb is taken to eliminate gas and bloating, for digestive and liver complaints and as a diuretic. It has also been used traditionally to treat ailments including rheumatism, gout, jaundice, colds and earaches.

Boldo has been clinically proven to aid digestion and is often combined with other plants such as fumitory and rosemary in remedies for dyspepsia.
