ABSCISIC Acid (ABA) a naturally occurring plant hormone has been identified in this invention with potent properties to fight cancer. ABA is able to produce a hyperpolarization condition on plasma membrane through a decrease of intracellular Na+ and K+. Such phenomenon is produced in cancer cells by mediation of ion channel and activation of the signaling g-protein pathway. ABA aborting sustained depolarization in malignant tissue will produce a change in the configurational state of cell from a damage to a normal state. additionally, a positive polarization of hCG outer layer accomplished through a removal of electrons will permit immune system cells coming close to cancer cells for destruction.
