The Unda Seroyal remedies are carefully constructed combinations of low potency homeopathic remedies. Instead of names, they are given numbers to designate the combinations. There are 76 combinations that are in use today.
They were developed in Europe by collaboration. Dr. Discri published a work describing them in 1937 after having worked with them for over 15 years.
A pharmacy in Belgium was responsible for making the combinations, and that evolved to the UNDA company in 1949, where they are made to this day. The operations of the company reflect exacting selection, processing, and production of the plants and metals necessary to produce a product which is tested with highly technical equipment to assure consistency of product and therefore predictable effectiveness of use.
