Description: The name given by the founder of the genus was Carib Simarouba, but later writers adopted the present spelling.
The tree is 60 feet or more in height, with many long, crooked branches covered with smooth, greyish bark, leaves 9 to 12 inches long, and flowers growing in small clusters, with rather thick, dull-white petals. The bark is usually found in pieces several feet long, the roots being long, horizontal, and creeping. Very often the outer bark has been removed, when it shows a pale yellowish or pinkish-brown surface. It is odourless, difficult to powder, and intensely bitter. It is usually imported from Jamaica, in bales.

Constituents: Simaruba root-bark contains a bitter principle identical with quassin, a resinous matter, a volatile oil having the odour of benzoin, malic acid, gallic acid in very small proportion, an ammoniacal salt, calcium malate and oxalate, some mineral salts, ferric oxide, silica, ulmin, and lignin.
It readily imparts its virtues at ordinary temperatures to water and alcohol. The infusion is as bitter as the decoction, whichbecomes turbid as it cools.
The main active group of chemicals in simarouba are called quassinoids, which belong to the triterpene chemical family. Quassinoids are found in many plants and are well known to scientists. The antiprotozoal and antimalarial properties of these chemicals have been documented for many years. Several of the quassinoids found in simarouba, such as ailanthinone, glaucarubinone, and holacanthone, are considered the plant’s main therapeutic constituents and are the ones documented to be antiprotozal, anti-amebic, antimalarial, and even toxic to cancer and leukemia cells.
The main plant chemicals in simarouba include: ailanthinone, benzoquinone, canthin, dehydroglaucarubinone, glaucarubine, glaucarubolone, glaucarubinone, holacanthone, melianone, simaroubidin, simarolide, simarubin, simarubolide, sitosterol, and tirucalla.
Medicinal Action and Uses: A bitter tonic. It was first sent from Guiana to France in 1713 as a remedy for dysentery. In the years 1718 and 1725 an epidemic flux prevailed in France, which resisted all the usual medicines. Simaruba was tried with great success, and established its medical character in Europe. It restores the lost tone of the intestines, promotes the secretions, and disposes the patient to sleep. It is only successful in the latter stage of dysentery, when the stomach is not affected. In large doses it produces sickness and vomiting. On account of its difficult pulverization, it is seldom given in substance, the infusion being preferred, but like many bitter tonics, it is now seldom used. From its use, it has been called ‘dysentery bark.’
Dosage: From 20 grains to a drachm. A 1/4 OZ. of simaruba may be infused for 12 hours in 12 OZ. of cold or boiling water, and a wineglassful of the infusion taken every three or four hours.
Fluid extract, 1/2 to 1 drachm.
CURRENT PRACTICAL USES
While at least one scientific research group attempts to synthesize one or more of simarouba’s potent quassinoids for pharmaceutical use, the plant remains an important natural remedy in the herbal pharmacopeias of many tropical countries and in the rainforest shaman’s arsenal of potent plant remedies. Natural health practitioners outside of South America are just beginning to learn about the properties and actions of this important rainforest medicinal plant and how to use it in their own natural health practices.
Simarouba bark tea is still the first line of defense for amebic dysentery and diarrhea among the natural products available. It’s also a good natural remedy for viruses. Although not widely available in the U.S. today, it can be found in bulk supplies and in various natural multi-herb anti-parasite and anti-viral formulas.

Other Species:
Simaruba glauca of Jamaica, San Domingo, Bahama Islands, Panama and Guatemala has identical properties, and by some writers is regarded as the same tree, others distinguishing it by a slight difference in the flowers. It is also known as Winged-leaved Quassia, and S. medicinalis.
S. versicolor of Brazil, has similar properties, the fruit and bark being also used as anthelmintics, and an infusion of the latter being employed in cases of snake-bite. The plant is so bitter that insects will not attack it, on which account the powdered bark has been employed to kill vermin.
S. glauca of Cuba furnishes a glutinous juice, which is employed in certain skin diseases.
S. excelsa or Quassia Excelsa yields quassin from boiled slices of the wood, furnishing the Quassia of commerce, substituted for the true Surinam Quassia.
Samadera Indica contains a similar bitter principle in its bark.
