Harm score: 1 (Natural substances)
Japanese nine-awn (Petasites japonicus), also known as Butterbur or Fuki, is a perennial plant native to East Asia, specifically Japan, Korea and China. This particular plant is characterised by its large, broad leaves and pale pink flowers that appear in spring. Its name is derived from the Greek, where the word 'petasites' means 'hat' or 'shade', a reference to its massive leaves. In our country, this plant is mainly grown as an ornamental, but in East Asia it is a common part of the local cuisine.
Japanese nine-oil is mainly used in gastronomy. The Japanese traditionally consider this plant a delicacy. They use it, for example, to prepare tempura or as an ingredient in various soups and sauces. The leaves and stems of the devetsil must be boiled before consumption to neutralise potentially dangerous alkaloids. The root of ninetsil is also used in traditional Chinese medicine for its anti-inflammatory properties. However, the use of this plant goes beyond gastronomy. In some countries, cosmetic products are also made from nine-tipsil. In the form of creams and ointments, it can help treat skin problems such as acne, eczema or psoriasis.
