My pulse rate before taking Mukta Vati, was 85-90 bpm which was too high, my blood pressure was also too high 165/ 95. After taking Mukta vati, 2 tabs in the morning, my blood pressure lowered to normal levels and my pulse rate lowered, all was well. However, I feel my pulse rate has lowered to the point that I am not getting enough oxygen into my blood. I was at a social gathering last night and felt extremely unwell, my heart was fluttering ( this was NOT a panic attack ) and I felt the need to walk about to almost "Kick start" my heart !!! I came back to normal relatively quickly, but am going to reduce the Mukta Vati to see if my heart rate improves, I was on the brink of asking someone to call an ambulance I felt that ill. I think you need to monitor your blood pressure and pulse and modify the dose to manage your symptoms. I used to suffer from moderate congestion, but now am fine, any moderate congestion is quite acceptable for me, the benefits of Mukta Vati are considerable, but with my recent "heart scare", as I said , I will only take one a day from now on and monitor the effects. I am 58 and a small lady 5ft 1", so maybe the higher dose is too much for me given my stature ? This is just a thought, but maybe stature doesn't come into it ?, I'd be interested to hear what other's think.
