Manmath Ras is an Ayurvedic formulation traditionally used for male vitality and sexual health. There is no specific maximum age limit for its use, as suitability depends on factors such as age, overall health, medical conditions, and individual needs. It should be taken only under the guidance of an Ayurvedic physician, especially in older adults or individuals with conditions such as high blood pressure, diabetes, or heart disease. The appropriate duration and continued use should be decided after evaluating your health condition.
