Allergies/Toxicity: 1 Mansonia is on the short list as one of the worst wood species in terms of toxicity and commonness of allergic reactions. Mansonia has been reported as a sensitizer, and though the most usual reactions simply include eye and skin irritation, the wood dust can also produce a wide range of other effects, including nausea, giddiness, sneezing, headaches, nosebleeds, infected splinters and asthma-like symptoms. Additionally, both the bark and heartwood have been found to contain cardiac poisons, which can cause heart disorders.
