Image of two tea bags of the brand Téi vum Séi. The herbs used in Téi vum Séi have been grown in the Obersauer Nature Park since 1992. The park is located in the northwest of Luxembourg’s Grand Duchy, where the upper Sûre artifical lake lies. The "Kraidergenossenschaft Uewersauer Nature Park”, a cooperative of local producers of herbal plants, was founded in 1993. Since then the cooperative has been working to promote the culture of aromatic and healing herbs, as well as processing and marketing the derived products as herbal tea and spices. Most of the herbs used for the "Téi vum Séi" products are grown in the fields of the members of the cooperative. Others are collected in the wild nature.
