I have similar problem with Mukta Vati. I had nasal congestion, and also more serious: unusually high exhaustion.
It was impossible to exercise to me when I was on Mukta Vati.
I am not sure if I am allergic to one of the component or something.
I am 40 year old so it not that concern me as for my mother that also used it and have very similar symptoms as I had.
It true that it significantly lower the blood pressure. But the exhaustion that it induce is very waring to me. I start using with 2 pills a day but it was whey too much. I ended up with 1/4 pill a day.

I'm bit surprise that may people posting testimonial after one day or one week of usage. That have no sense. You should at list wait couple moth so you know what the full reaction of your body is on the specific.

From what I reading almost nobody reported any side effect - that very surprising to me.
I wonder if all Mukta Vati equal.
I purchase my form:
http://www.herbs2healyou.com/mukta-vati.html

It Ivy's Comm System marketed and manufacture by Amar Pharmaceuticals.
Good idea for despondence to write the manufacture so we can choose the best product

The inexpedience quantity on the bottle show as follow:
Centella Asiatica 35mg
Convolvulus Pluricaulis 35mg
Terminalia Arjuna 35mg
Onosma Bracteatum 35mg
Celastrus Paniculatus 15mg
Inula Racemosus 15mg
Withania Somnifera 30mg
Tinospora Cordifolia 3mg
Corallium Rubrum 50mg
Pearl Powder 20mg
In most description there is talk about 8 ingredients, the above have 10.

I see on there manufacture have different ratio of the herbs used in the product.

Does anybody have some idea which inexpedience my cause exhaustion?
May be other brand might be better.
Can anybody sher what other bred they using with what effect?

Yes, I experience the same thing. I was told that some people will experience nasal congestion and sometimes a feeling of being tired. I was instructed to decrease the amount of pills I take. Well, I did that, and both went away, the nasal congestion and the feeling of being tired. Just decrease the amount of pills little by little maybe one or two, or until it goes away. Do it gradually.
