A computer-implemented method and system is disclosed for modifying the properties of a consumable liquid to preventively treat or functionally correct human health conditions. The system includes a database storing human health conditions and an electronic device having a processor communicatively coupled to the database. The electronic device captures at least one visual image or video of a face of a person over a defined period of time via a digital camera. The captured images or video are processed by the electronic device to obtain the persons cardiointervalogram. From the cardiointervalogram, the electronic device identifies a particular human health condition of the person by comparing slow wave parameters of the cardiointervalogram to the corresponding human health conditions stored in the database. The electronic device then determines specified properties for light waves and/or acoustic waves based on the identified health condition(s). Light waves and/or acoustic waves having the specified properties are thereafter emitted from a light source and/or audio source to the consumable liquid to modify the properties of the consumable liquid to preventively treat or functionally correct the health condition(s).
