Usage in traditional medicine
Though little information is available, Z. zamiifolia is apparently used medicinally in the Mulanje District of Malawi and in the East Usambara mountains of Tanzania where juice from the leaves is used to treat earache.[10]
In Tanzania a poultice of bruised plant material from Z. zamiifolia is used as a treatment of the inflammatory condition known as "mshipa".[11]
Roots from Z. zamiifolia are used as a local application to treat ulceration by the Sukuma people in north-western Tanzania.[12]
Chemicals
Zamioculcas zamiifolia contains acylated C-glycosylflavone apigenin 6-C-(6″-O-(3-hydroxy-3-methylglutaroyl)- β-glucopyranoside)[7]
Air purification
The plant has air purifying qualities for the indoor environment. A Study from Department of Plant and Environmental Science at the University of Copenhagen from 2014 shows the plant is able to remove volatile organic compounds in this order of effectiveness, benzene, toluene, ethylbenzene and xylene at a molar flux of around 0.01 mol/(m2 day)[13]
Toxicity
Zamioculcas zamiifolia is part of the family Araceae, which includes many poisonous genera, such as Philodendron, which contains calcium oxalate.
An initial toxicological experiment conducted by the University of Bergen in 2015 on extracts from Z. zamiifolia using brine shrimp as a lethality assay did not indicate lethality to the shrimp even at concentrations of extracts up to 1 mg/mL. The scientists conducting the experiment found that "On the contrary, it could appear as though the extract contributed to improvements in the vitality of the larvae".[7]
