“Best service, love Yes Chinaherb been using them for years both in NSW and VIC. And also NZ (Materia Medica). KO DA is a fantastic brand to use. It provides me with complete confidence prescribing herbs with patients. I can assure them that the herbs I give them are tested for heavy metals, toxins and are medical-grade. I also see quicker results in practice.” – I.S., Melbourne via Facebook
