The most important active ingredient is volkensin - this is a potent inhibitor of eukaryotic protein synthesis in whole cells as well as in cell-free systems. The inhibitory activity is a function of the A subunit; the B subunit has a lectin function and allows the protein to pass the intact cell membrane. Volkensin is one of the most lethal double-chain ribosome-inactivating and ricin-like toxins. Chemically, it resembles most closely modeccin, the toxin of Adenia digitata. It causes neuron death not only at the injection site, but it is also transported between neurons. Possibilities have also been studied of selectively killing mononuclear macrophages, the cells in which the HIV virus survives and which transfer it to T-cells in which the virus is rapidly multiplied resulting in the development of Aids[
