Bee acids. Apitherapy is a branch of alternative medicine that uses honey bee products, including raw honey, royal jelly, pollen, propolis, beeswax and apitoxin (Bee venom). The claim that apitherapy treats cancer, which some proponents of apitherapy make, remains unsupported by evidence-based medicine. The painful stings of bees are mostly associated with the poison gland and the Dufour's gland which are abdominal exocrine glands containing various chemicals. In "Lasioglossum leucozonium", the Dufour's Gland mostly contains octadecanolide as well as some eicosanolide. There is also evidence of n-triscosane, n-heptacosane, and 22-docosanolide. However, the secretions of these glands could also be used for
Evolution of snake venom model described above, in which genes in other body tissues are duplicated and then recruited to the venom gland before natural selection for toxicity. However, in 2014 a new model was proposed in which salivary protein genes are duplicated and then restricted to the venom gland. This model does away with the recruitment hypothesis and cites the homology between certain venom and body genes as unrelated in the linear fashion described in the traditional birth-and-death model. Gene duplication is not the only way that venom has become more diverse. There have been instances of new venom proteins generated by alternative
