A composition including plant extracts that synergistically treat or inhibit pathological conditions and a method for developing the composition is provided. The composition includes bioactive chemical agents extracted from the Plantago major plant species including, but not limited to, acetonide, catalpol, hispidulin, loliolide, neptin, rhamnose, and scutellarin, and bioactive chemical agents extracted from the Mentha spicata plant species including, but not limited to, cadinol, diosmetin, eugenol, furfural, hesperidin, luteolin, and piperitone. The method includes the steps of washing Plantago major and Mentha spicata plant material, freezing the plant material, cutting the frozen plant material into pieces, heating the plant material in purified water to form a resultant solution containing Plantago major and Mentha spicata plant extracts, cooling the resultant solution, and filtering the Plantago major and Mentha spicata plant material out of the resultant solution to produce the composition.
