Cinchona is a small-sized tree. Leaves are opposite, entire, elliptical, and pointed at both ends. Flowers are white or pinkish, occurring in panicles, and have a pleasant odor. Corolla is tubular, 5-lobed, fringed along the edges with long hairs. Fruit is an ovoid or sub cylindrical capsule, with the peculiarity of opening from the base, hanging downward while the valves remain together at the tip. Seeds are numerous, flat, and winged all around.
- Thrives best at medium and high elevations in tropical and warm countries.
- In the Philippines, thrives best
in Impalutao (762 meters) and Kaatoan (1,057 to 1,372 meters) in Bukidnon.
- Several species of Cinchona have been tried in the Philippines, and after a weeding out of unsuitable species, three have been noted - Cinchona ledgeriana Moens, C. succirubra Pavon, and C. officinalis Linn. For a long time C. ledgeriana has been referred to as C. calisaya Wedd., and is sometimes called C. calisaya var. ledgeriana.
- Some authors consider C. officinalis to apply to a species that naturally grows in the Andes oif southern Ecuador, containing only traces of quinine, or no quinine at all. The cultivated species, C. calisaya, is similar to C. officinalis, but produces significant quantities of quinine. Many authors have used C. officinalis for the cultivated species, and consequently, photos and studies have been misapplied.
- Cinchona tidbit: Cinchona bark harvested from the South American rainforests was a source of commerce for the manufacture of quinine drugs. In the mid-19th century, seeds of C. calisaya and C. pubescens were smuggled out of South America by the British and the Dutch. However, planting and cultivation of the smuggled seeds produced a harvest of low quinine content with no commercial prospect. A more successful venture came from smuggled seeds of Cinchona ledgeriana out of Bolivia, that established extensive plantations of quinine-rich cinchona trees in Java, soon dominating the world production of quinine. By 1918, the Dutch "kina bureau" in Amsterdam controlled the majority of the world's supply of quinine.
- About 30 alkaloids have been isolated from the cinchona bark; four are considered important: quinine, cinchonine, quinidine, and cinchonidine.
- Cinchona bark is well-known source of quinine used as a cure for malaria.
Philippine totaquina compares favorably with quinine.

• Renal Cancer Preventive: Study evaluated the protective role of C. officinalis preventing the carcinogenic effect on the kidney of albino mice induced by heterocyclic amine "mutagen." Results showed CO modulated the carcinogenic effects of the toxic mutagen in the kidneys. Electron microscopy indicsted improved cellular organization in mice treated with C. officinalis.
