Boxwood (Buxus sempervirens)



(Buxus sempervirens)

Boxwood-BushBoxwood Bush

It is a very popular ornamental plant in gardens, being particularly valued for topiary and hedges because of its tolerance of close shearing, small leaves, and scented foliage. Several cultivars have been selected, including ‘Argenteo-variegata’ and ‘Marginata’ with variegated foliage, and ‘Vardar Valley’, a slow-growing semi-dwarf cultivar.

The wood (“boxwood”) is very hard (possibly the hardest in Europe) and heavy, making it ideal for cabinet-making, the crafting of clarinets, engraving, marquetry, woodturning, tool handles, mallet heads and as a substitute for ivory. The noted English engraver Thomas Bewick pioneered the use of boxwood blocks for engraving.

The leaves were formerly used in place of quinine, and as a fever reducer.
The species is locally naturalized in parts of North America.

Toxic Principle:
The toxic principle of this plant is a quinine type toxin.

Poisoning Symptoms include:
Mild nausea may be the only symptom, but with large overdoses profuse vomiting, abdominal pain, and diarrhea may occur. These result from a combination of the local irritant effect of quinine on the gut and the central effects of quinine on the chemoreceptor trigger zone. Vasodilatation and sweating are well recognized, and tinnitus is common. Visual symptoms usually are delayed, and blindness may not be discovered for a day or more.
