Botanical illustration of boldo (Peumus boldus)
Boldo (Peumus boldus) is a perennial tree, generally about 6 - 7m. height (sometimes up to 20m.) It is distinguished by its characteristic lemon and camphor smell.
This plant receives great phylogenetic interest, since it is one of the families of plants older along with the Aquifoliaceae. Boldo is a monotypic tree, that is, the only species of its genus.
It is a slow-growing tree, which blooms at 4 or 5 years.
It has a rounded cup, very branched, with dense glaucous or green foliage.
Boldo brittle leaves are opposite, petiolated, elliptic, whole, with obtuse appex. The surface of the leaves is rough, since they are covered by glandular protuberances. The flat underside, with pronounced ribs.
It is a dioic tree, so there are male and female trees. To produce fruits, flowers must be pollinated by insects.
The fruit is a small fleshy drupe (1-2 cm in diameter), yellowish green at maturity, very aromatic and edible, with a sweet taste. This can remain in the tree until the following season, turning to black color.

Essential oils can be used in perfumery. Necklaces and handicrafts are made from dry fruits, which, when heated by the sun, give off a pleasant smell.
Composition of boldo
Among all the components of the boldo, the presence of isoquinoline alkaloids (0.2-0.5%) stands out. The plant contains about 20 alkaloids derived from aporphine, the most important being boldine, which represents 25-30% of the total alkaloids.
Boldine and its derivatives have hepatoprotective, anti-inflammatory, antioxidant, choleretic, gastro-stimulant, muscle relaxant and immunomodulatory properties. At high doses it has a hypnotic, convulsive and abortive effects.
