Yes the tablets named are to be taken three times a day. one tablet each of allerin, gandhak rasayan and punarnava mandur and liquid mahamanjishtha arisht is to be taken twice a day with equal quantity of water in it. This can also be taken along with tablets morning and night dose.Need not to be taken on empty stomach. Have it half hour after having meals.
these medicines will be available from any shop dealing with ayurvedic medicines.
There is no side effect of these medicines. The notion that ayurvedic medicinies have no side effect is true if you take it within prescribed limits, overdosage of water even can cause restlessness
. so have no worry about side effect here as there is no such data yet.
one thing you may feel will be black stools this can be due to punarnava mandur as it has iron content in it which we usually give to add glow to face. you need not worry on all these fronts i believe.
you are welcome for any more clarification.
