Tarragon: benefits, dosage, contraindications

Updated on

Tarragon is a perennial herb highly appreciated in Western cuisine for its anise-like aroma. Tarragon is often used to flavor various dishes and sauces. The aerial parts of tarragon are used for the extraction of its essential oil. Tarragon essential oil contains about 81% estragole, an organic compound that gives the oil its characteristic properties and aniseed-like taste similar to anethole found in tropical basil oil. Besides estragole, tarragon is also a rich source of potassium, making it a beneficial herb for maintaining the body's electrolyte balance. It also contains other constituents such as alpha-pinene, alpha-trans-ocimene, volatile oils, alkylamides, and various coumarin derivatives. Traditionally, tarragon is used to relieve various digestive ailments such as dyspepsia, lack of appetite, nausea, and postoperative vomiting.

Tarragon is being explored for the treatment of neurological conditions like epilepsy and Alzheimer's disease, due to its essential oil which has demonstrated dose-dependent anticonvulsant activity in animal models. Furthermore, tarragon extract has shown to reduce neuronal demyelination and pro-inflammatory cytokine levels in mice. In the laboratory, tarragon also inhibits monoamine oxidase (MAO) enzymes, suggesting potential benefits for neurodegenerative disorders.
