herbal supplementation

Just curious as to how many neijia practitioners here have been encouraged by their sifus to take supplemental herbs with their training (internally). I’m not talking about to rectify a problem or illness but as a general aid/tonic. I 'm wondering if for neijia practitioners chi qong and zhan zhuang are supposed to be enough or if they supplement. thanks-

At the current moment my external style teacher recomends various types of herbal medicines for us.
