Red gum is not particularly dangerous or toxic.
Red Gum Milled
Red gum, or acaroid resin, is one of the most widely used organic fuels in modern pyrotechnics and is particularly effective with Potassium perchlorate. It is made from the excretions of Grass Trees (Xanthorrhoea Genus), native to Australia. Red gum is soluble in many conventional solvents; alcohols, ethers, and ketones. Ethanol, methanol, acetone, isopropanol, and butanone are commonly used in pyrotechnic preparation. It also can be used as a binder.
