Hypertension is a major cause of mortality known as the "silent killer". It has primary causes like genetic and environmental factors and secondary causes like renal and endocrine diseases. In Ayurveda, it is understood as Raktagata Vata. The document discusses Takradhara Shirodhara for treating hypertension, where medicated buttermilk containing Amalaki kashaya is poured over the forehead in an oscillating motion. It helps reduce blood pressure levels by activating the parasympathetic nervous system without side effects, making it preferable to modern antihypertensive treatments for long-term management.
