Blurry Vision After Taking Mukta Vati - #51624

Hi, My girlfriend (87 y) takes Mukta vati to control her blood pressure. She suffered a couple of years from a heavy heart attack followed by heart failure. Using mukta vati (in the morning and at noon during the meals) worked wonderful to maintain the blood pressure within normal limits. But yesterday night she woke up with a high blood pressure and she took a mukta vati (without food) and in the morning she woke up with a blurry vision. Is there a relationship and what can be done, since the blurry vision persist all day long now.
