Tonic herbs do not force the body to change, but rather work with it to adapt, allowing a measured, nourishing and normalising effect to unfold within the body and its systems.Traditionally consumed daily to promote longevity and prevent illness, these remedies offer nourishment to the vital organs, strengthen essential functions and improve quality of life, without negative side effects. Tonic herbs are further categorised as Yin, Yang, Qi and Blood & Shen tonics.
