Analgesic; Antiseptic; Bitter; Cholagogue; Diuretic; Stimulant; Tonic.

Boldu is a traditional remedy used by the Araucanian Indians of Chile as a tonic. The plant stimulates liver activity and bile flow and is chiefly valued as a remedy for gallstones and liver or gallbladder pain[254]. It is normally taken for only a few weeks at a time, either as an infusion or as a tincture[254]. It is often combined with other herbs such as Berberis vulgaris or Chionanthus virginicus in the treatment of gallstones[254]. The leaves are analgesic, antiseptic (urinary), bitter, cholagogue, diuretic, stimulant and tonic[4, 46, 165, 235]. They are considered a valuable cure for gonorrhoea in S. America[4]. The plant is taken internally in the treatment of liver disease (though the bark is more effective here), gallstones, urinary tract infections, intestinal parasites and rheumatism[238]. It has been used in the past as a substitute for quinine in the treatment of malaria[238]. The leaves are harvested during the growing season and are dried for later use[238]. Some caution is advised, the plant should not be used by pregnant women[254]. See also the notes above on toxicity. A volatile oil obtained from the plant destroys internal parasites[238]. Alkaloids contained in the bark are a stimulant for the liver[238].

Other Uses

Beads; Charcoal; Dye; Essential; Repellent; Tannin.

The bark is a source of tannin and is also used as a dye[1, 4, 238]. A deliciously fragrant essential oil is obtained from the leaves[245]. The dried and powdered leaves are scattered amongst clothes to sweeten them and repel insects[245]. The small fruits are dried and used as beads in necklaces[245]. When warmed by the body or the sun they release the scent of cinnamon[245]. The wood is used for making charcoal[4].

Scented Plants

Plant: Fresh Crushed Dried

The leaves have a lemon-camphor aroma.

Cultivation details

Dislikes soils that are too moist[166]. Prefers a well-drained acid sandy soil in full sun[166, 200, 238]. Hardy in climatic zone 9 (tolerating occasional light frosts), this plant normally requires greenhouse protection in Britain but is capable of withstanding light frosts and might succeed outdoors in the mildest areas of the country, especially if grown against a sunny wall[166, 200]. One report says that the plant succeeds outdoors at Kew Gardens in London, where it often flowers all year round[245]. All parts of the plant are sweetly aromatic[245]. The leaves have a lemon-camphor aroma[238]. Dioecious, male and female plants must be grown if fruit and seed is required[238].

Propagation

Seed - sow spring in a warm greenhouse. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in early summer and give them some protection from winter cold for at least their first winter or two outdoors. Cuttings of half-ripe wood, July/August in a frame[200]. Grow the cuttings on in the frame or greenhouse for at least their first winter.

Not sure if my earlier comment got thru (internet blipped out) - I also am interested in a source for a boldo plant or seed. Will ask our son who is in Argentina about this - do not feel TOO concerned about the possibility of introducing a potentially invasive plant to Arizona, based on your description - I believe it would not survive out cold winters (20 F EVERY winter, 0 F occassionally.
