Tonics
Tonics are not recommended for use during any stage of wind invasion, i.e. cold & flu. They tend to drive wind deeper into the body, delaying recovery. (Qi tonics can be warm and stagnating to energy and should be discontinued or moderated if heat or dryness, chest oppression, abdominal congesting, bloating occur. Tonics to nourish blood may cause indigestion and should be monitored if so.)
