All raw materials and plants which WALA wishes to use are first tested for purity in the company's analytical laboratory. Only after they have passed these strict tests can they be used for manufacture. Production takes place under strict hygienic conditions and regular controls are carried out at all stages of the process. The finished product is inspected by experienced staff who check its smell, consistency and colour. Only when all tests have been passed can filling of the finished product take place.

These extensive controls conform to international standards of pharmaceutical manufacturing and apply at WALA not only to the production of pharmaceuticals but also to the skin care products and the Dr.Hauschka Med products.
