The specific epithet officinalis comes from a medieval laboratory workshop: plants usable in pharmaceuticals, herbal medicine, liquor, perfumery and the like.
Geographic Distribution and Habitat –
Cinchona officinalis is a plant native to the humid montane forests of Colombia, Ecuador, Peru and Bolivia.
Its habitat is that of cool and humid mountain areas, between 1600-3000 meters above sea level.
Cinchona officinalis is a plant in the form of an evergreen shrub or tree that grows between 6 and 20 meters.
The bark is wrinkled and the twigs are covered with tiny hairs.
The stipules are lanceolate or oblong, acute or obtuse, glabrous.
The leaves are lanceolate to elliptic or ovate, usually about 10 centimeters long and 3.5-4 centimeters wide, with a pointed, sharp or obtuse tip, rounded base, leathery, glabrous above and often shiny; below they are hairless or powdery especially on the veins.
The inflorescences are in terminal panicles, with multiple flowers; the calyx is reddish, hairless or almost, with triangular lobes; pink or red corolla, ovate, acute lobes, with the corolla tube about 1 cm long.
The fruit is an oblong capsule, 1,5–2 cm. in length, almost hairless.
Cinchona officinalis is a plant of the humid tropics, where it is found at altitudes between 1,600 and 3,000 meters and grows best in areas where annual daytime temperatures are between 14 and 23 ° C, but can tolerate temperatures between 7 and 27 ° C.
This plant can’t stand temperatures of 7 ° C or lower.
It prefers an average annual rainfall of between 2,500 and 3,500 mm, but tolerates 1,400 – 4,000 mm.
It also requires a well-drained and humid soil and a position in full sun or partial shade.
It grows very poorly or not at all on soils that have been exposed to fire and prefers a pH between 5.5 and 6.3, tolerating values of 4.8 – 7.
Plants start flowering after 3 – 4 years and are uprooted and harvested after 8 – 12 years.
In commercial plantations, trees are given away when they are about 6 years old.
Customs and Traditions –
Lojabark has a long history of use by the natives, especially as a treatment for fevers and malaria. Modern research has shown that it is a very effective treatment for fever, and especially as a treatment and prevention of malaria. The bark contains various alkaloids, in particular quinine and quinidine. Up to 70 – 80% of the total alkaloids contained in the bark are composed of quinine.
The bark is bitter, astringent, tonic, lowers fever, relaxes spasms, is antimalarial (the quinine alkaloid) and slows the heart (the quinidine alkaloid).
The cortex is used internally in the treatment of malaria, neuralgia, muscle cramps and cardiac fibrillation. It is an ingredient in various patented cold and flu remedies. The liquid extract is useful as a cure for drunkenness. It is also used as a gargle to treat a sore throat.
However, high and too constant doses should be avoided, as they produce headache, dizziness and deafness.
Preparation Method –
The bark is made into tablets, liquid extracts, tinctures and powders. The alkaloid quinine extracted from the bark is used in hair oils and shampoos, tanning oils, insecticides and as a vulcanizing agent.
In the right dose it is also used to make drinks fluorescent yellow.
