In April 1995, a new Drug Act became effective, which closely resembles the EU regulations for the pharmaceutical sector. The law does not distinguish between medicinal products made from chemical substances and those made from plants or natural substances. Under the law, proof of quality, safety and efficacy became an essential pre-condition for the registration of drugs. Registration of borderline products was expected to be published in 1996. Some plant-based products are included under a simplified procedure. These consist only of non-prescription products with restricted claims, which are suitable for self-medication .
