Customs and Traditions –
Cinchona micrantha has long been used medicinally by natives of South America to treat fever and a number of other conditions. The bark of this species, as well as of several related species, has been shown to contain quinine, an effective antimalarial and febrifuge.
At the beginning of the 17th century, Europeans became aware of the effectiveness of this tree’s bark in treating malaria, and over the next 200 years, the trees were largely over-exploited in nature until commercial plantations were finally established in Java. .
Later it was largely replaced by synthetic drugs, in the second half of the 20th century, quinine became very important in the treatment of malaria again because various strains of malaria developed resistance to synthetics.
The bark contains various alkaloids, in particular quinine and quinidine. The bark is a bitter, astringent, tonic herb that lowers fever, relaxes spasms, is antimalarial (the quinine alkaloid) and slows the heart (the quinidine alkaloid).
The bark is made into various preparations, such as tablets, liquid extracts, tinctures and powders.
It 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. It is also used as a gargle to treat a sore throat.
Powdered bark is often used in dental powders due to its astringency.
In any case, high and too constant doses must be avoided, as they produce headache, dizziness and deafness.
Preparation Method –
The bark is made into tablets, liquid extracts, tinctures and powders. When consumed in large quantities, however, it can cause headaches, dizziness and deafness.
Quinine, extracted from the bark of the tree, is used as a bitter flavoring for tonic water and carbonated drinks.
