Summary
Cinchona officinalis, otherwise known as Lojabark, is an evergreen shrub or small tree of about 6 - 20 m tall found in western South America particularly in Ecuador. Like other species under the same genus, it has long been used by native people in the treatment of fever and malaria. The bark is also used in the treatment of neuralgia, muscle cramps and cardiac fibrillation. It is made into tablets, liquid extracts, tinctures and powders. Alkaloid quinine extracted from the bark is used in hair oils and shampoo, sun-tan oil, insecticides, and as a vulcanizing agent.
Physical Characteristics
Cinchona officinalis is an evergreen Tree growing to 8 m (26ft) by 8 m (26ft) at a medium rate.
It is hardy to zone (UK) 10.
Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid and very alkaline soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Medicinal Uses

Lojabark has a long history of native use, especially as a treatment for fevers and malaria. Modern research has shown it to be a very effective treatment for fevers, and especially as a treatment and preventative of malaria. The bark contains various alkaloids, particularly quinine and quinidine. Up to 70 - 80% of the total alkaloids contained in the bark are quinine[ 418 ]. The bark is a bitter, astringent, tonic herb that lowers fevers, relaxes spasms, is antimalarial (the alkaloid quinine) and slows the heart (the alkaloid quinidine)[ 238 ]. The bark is made into various preparations, such as tablets, liquid extracts, tinctures and powders[ 238 ]. It is used internally in the treatment of malaria, neuralgia, muscle cramps and cardiac fibrillation[ 238 ]. It is an ingredient in various proprietary cold and influenza remedies[ 238 ]. The liquid extract is useful as a cure for drunkenness[ 418 ]. It is also used as a gargle to treat sore throats[ 238 ]. Large and too constant doses must be avoided, as they produce headache, giddiness and deafness[ 418 ].

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details
Industrial Crop: Medicinal Management: Coppice Minor Global Crop
A plant of the moist tropics, where it is found at elevations from 1,500 - 3,000 metres. It grows best in areas where annual daytime temperatures are within the range 14 - 23°c, but can tolerate 7 - 27°c[ 418 ]. It can be killed by temperatures of 7°c or lower[ 418 ]. It prefers a mean annual rainfall in the range 2,500 - 3,500mm, but tolerates 1,400 - 4,000mm[ 418 ]. Requires a well-drained, moist soil and a position in full sun or partial shade[ 238 , 418 ]. It grows very poorly or not at all on soils that have been exposed to fire[ 418 ]. Prefers a pH in the range 5.5 - 6.3, tolerating 4.8 - 7[ 418 ]. Plants start flowering after 3 - 4 years, and are uprooted and harvested after 8 - 12 years[ 418 ]. In commercial plantations, the trees are coppiced when about 6 years old[ 238 ].
Carbon Farming
-
Industrial Crop: Medicinal
Most pharmaceuticals are synthesized from petroleum but 25% of modern medicines are based on plants.
-
Management: Coppice
Cut to the ground repeatedly - resprouting vigorously. Non-destructive management systems maintaining the soil organic carbon.
-
Minor Global Crop
These crops are already grown or traded around the world, but on a smaller scale than the global perennial staple and industrial crops, The annual value of a minor global crop is under $1 billion US. Examples include shea, carob, Brazil nuts and fibers such as ramie and sisal.
