Anton Hübner GmbH & Co. was founded in 1936 when Hübner purchased the license to produce the "Tannenblut" (literally fir tree blood) natural flu and cold medicine. This formula had been developed in the 1920's by a cleric, Parson Hurst, and his pharmacist friend, Dr Eduard Hiepe, and was made using pine tree honey, branch tips of green fir trees, and forest and meadow herbs native to the Black Forest area that were known >to have agreeable effects on the respiratory system.
