Erhard Diwald, Managing Director of Plantapharm, took over the family business from his parents Dr Karl (biologist and chemist) and Dr Gerdraud Diwald (biologist with pharmacological specialisation) in 1965. At that moment in Plantapharm, Erhard Diwald set a new focus on the development and production of plant extracts for the cosmetics and dietary supplements industry as well as on the distribution of raw materials and auxiliary supply substances in these areas. Step by step, the drug stores were closed. Over time, Erhard Diwald has been able to successfully take on Austrian representations of internationally renowned companies for source and auxiliary substances as well as active agents for the cosmetics and food industry.
