Dear you have not mentioned the readings of BP before and after sarpgandha vati. When the BP is very high many a times this proves to be ineffective to lower the BP to desired limits. Long standing malignant hypertension
many a times come with facial oedema, but oedema of legs and feet should not be ignored as this is also symptom of renal involvement. Get all tests done , if everything is fine then add shirodhara
to existing treatment.
