Harm score: 2 (Derivatives of natural substances)

Estragole, also known as p-allylanisole or Methoxy-4-(prop-2-en-l-yl)benzene, is an organic compound whose name is derived from the old name for the wild herb chamomile, estragon, which is one of the main sources of the substance. It is a transparent to slightly yellow liquid with a characteristic sweet, spicy and aniseed-like odour. It is an ether derivative of phenylpropene, specifically the methyl ether of anethole.

Estragole is considered to be the main constituent of tarragon and basil essential oils, which are used in many industries. Due to its anise aroma, it is often used in the food industry, for example in the production of liqueurs, candies or even toothpaste. In the cosmetics industry, it is used to make perfumes and cosmetic products. It is also used in aromatherapy, where it is valued for its calming effects. It should be noted, however, that despite the widespread use of tarragon in various industries, its safety is questionable. Some studies suggest that it may have carcinogenic effects and therefore its consumption should be limited. In the European Union, its use in food is strictly regulated.
