The complex production method for our golden millet oil is closely-guarded secret. Once again, it is also based on the unique Kollath method, which is used only by Zwicky and has been specially refined just for this purpose. After a 12-year development period we are now able to extract a pure golden millet oil from Goldhirse®. The result is unique. The valuable golden millet oil is the basis for our Hirsana golden millet oil capsules, which demonstrably ensure beautiful hair, skin and nails.
