    that only 100 grams of plant material are needed to kill an adult horse. So I googled the weight of a horse and found it could be expected to be between 380 and 550 kg, so to keep the maths easy the horse is between 4 and 5 times the mass of the 100kg human you used in your example. That makes Oleander at least 10 times as toxic as eucalyptus.
    Sounds about right.
    100g in 500 kg is 0.2g/kg ,about the same as Eucalyptus oil.

    I read somewhere that someone died by drinking a tea made with just a few leaves (estimate 5 g of leaves and 50 kg person)
    that makes the toxicity of the leaves <0.1 g/kg which is consistent with the figure for the horse

    I got sick of sitting around doing nothing - so I took up meditation.

    I've done some work with oleander, specifically the toxic agent oleandrin and its precursor oleandrigenin. Oleandrin is a cardiac glycoside and it kills you by, essentially, giving you a heart attack. Not very nice. There are at least a half dozen related glycosides in oleander. They are not destroyed by boiling or drying of the plant material, extraction and quantitation of these agents was part of the work I did. Oleander extract was investigated for a while as cancer treatment (https://www.ncbi.nlm.nih.gov/pubmed/11001386).
    Innovations are those useful things that, by dint of chance, manage to survive the stupidity and destructive tendencies inherent in human nature.
