SIMAROUBACEAE

(Quassia family)

 

120 species in 20 genera are found in tropical and sub-tropical regions.

Many species of the family contain bitter principles such as quassine. Quassia (Surinam quassia) and Aeschrion (syns Picraena, Picrasma) (Jamaica quassia) have been used medicinally.

[Summary yet to be added]


Ailanthus altissima Swingle var altissima
(syns Ailanthus glandulosa Desf., Pongelion glandulosum Pierre)
Tree of Heaven, Chinese Sumac, Stink Tree

Ellis (1756/7) referring to a tree later identified by Swingle (1916) as the tree of heaven, observed that the odour of the foliage is intensely disagreeable and can cause headache and nausea. Rhinitis and conjunctivitis may also ensue (Blumstein 1943). The disagreeable odour of the male flowers is said to be carried by the pollen but the leaves and twigs are malodorous if rubbed or bruised only slightly (Swingle 1916).

Stuart (1911), referring to Ailanthus glandulosa, noted that in Chinese traditional medicine, the leaves of the plant are used to prepare a wash to promote the growth of hair and to treat parasitic ulcers and eruptions. The bark and root, known as Chun Pi, Chun Gen Pi or as Chuen Gen Bi, may be similarly used. Huang (1993) states that Chun Pi has haemostatic properties.

White (1887) remembered a case report of dermatitis of the face from the plant but he could not find the reference. He also received a personal communication of the case of a lady who was poisoned by contact with the tree. Various authors, including Pammel (1911), Webb (1948a), and Muenscher (1951) have recorded or added to these notes but there is a conspicuous paucity of further case reports. Gardner & Bennetts (1956) simply include Ailanthus glandulosa in a list of plants known or suspected of causing dermatitis. White (1887) may have been referring to a report of Cornevin (1887) that gardeners pruning the tree of heaven may get vesicular eruptions on the face and hands. It is possible that these reports from the 19th century related to contact with Toxicodendron vernicifluum F. Barkley, fam. Anacardiaceae misidentified as Ailanthus glandulosa (Remington et al. 1918). Referring to A. glandulosa and noting a report that this species should be regarded with suspicion, Coulter (1904) claimed that he had handled the tree of heaven for years, and had encouraged others to do so, but that he had failed utterly to find it at all poisonous or irritating. The recent literature provides a single case report (Derrick & Darley 1994) of an urticarial eruption followed by widespread dermatitis in an agricultural student who came into contact with the plant.



Ailanthus integrifolia Lam. ssp integrifolia
Ferntop Ash, White Bean, White Siris

According to Conn & Damas (2005c), in their online Guide to Trees of Papua New Guinea, this species bears stinging hairs.



Ailanthus triphysa Alston
(syns Adenanthera triphysa Dennst., Ailanthus imberbiflora F. Muell., Ailanthus malabarica DC.)
Ferntop Ash, White Bean, White Siris

The various forms of Ailanthus malabarica furnish a quantity of resin which, according to Dr Lauterer, makes a good ointment for chronic ulcers. Fresh cuts and sores, however, should not be treated with this resin, on account of the acrid oil (Webb 1948a).



Picrasma excelsa Planchon
(syns Aeschrion excelsa Kuntze, Picraena excelsa Lindl., Quassia excelsa Sw., Simarouba excelsa DC.)
Bitterwood, Jamaica Quassia, Lofty Quassia, Peste à Poux

Barham (1794) said that workmen disliked working with Jamaica quassia because it "bittered" their mouths and throats; Stone (1921) quoted an account of temporary paralysis in a dog's legs after its ulcers had been bathed with a decoction of the wood. According to Woods and Calnan (1976) these reports hardly seem to justify Moll's (1950) claim that it is the "most feared" wood in South America for which he quotes no evidence.

The wood and bark are used as a substitute for Surinam quassia (Quassia amara L.). A benzoquinone is derived from the tree (Polonsky and Lederer 1959).



Quassia amara L.
(syn. Simarouba amara)
Surinam Quassia, Stave Wood

The bark of Simarouba amara and Khaya senegalensis and the wood of Picrasma crenata contain 2,6-dimethoxybenzoquinone (Polonsky and Lederer 1959). This was one of the quinones which produced positive patch test reactions in Heyl's (1966) case of dermatitis from Bowdichia. Woods and Calnan (1976) refer to a report of Prefontaine (1763) that negroes stripping the root-bark of simarouba (perhaps not S. amara) wore protective clothing because the sap would cause "gale" severe enough to prevent them working for some days.

Quassia amara yields Surinam quassia (Budavari 1996). An extract of quassia wood, used as an insecticide, caused dermatitis (Artom 1959, Semmola 1963).
