I advise removing drugs before adding them back. From experience herbals are very hit and miss, and might interact with things you're consuming anyway.
One might contemplate, in regard: "It seems that perfection is attained not when there is nothing more to add, but when there is nothing more to remove." -Antoine de Saint Exupéry
But everyone's different. I just feel that with our western diets, we are usually pretty well compensated for human beings.. that we over-compensate and create imbalances/cause our bodies to work in ways they shouldn't. A proper resting period (a fast) might be the best thing for us when faced with situations like these/illness, as it lets our bodies rebalance themselves, as they know how to do, much of the time.
