Asarone, which includes alpha (trans) and beta[3] (cis) types, is an ether found in certain plants such as Acorus and Asarum.[2] As a volatile fragrance oil, it is used in killing plant fungal[4] pests and bacteria.[5] The toxicity and carcinogenicity of asarone means that it may be difficult to develop practical anthelmintics and insecticides based on it.[6]

Pharmacology

The main clinical symptom of asarone is prolonged vomiting that sometimes lasted more than 15 hours. Asarone is not metabolized to trimethoxyamphetamine as has been claimed by online vendors.[7]

β-Asarone may be a potential candidate for development as a therapeutic agent to manage cognitive impairment associated with conditions such as Alzheimer's disease.[8]

The Council of Europe Committee of Experts on Flavouring Substances concluded that β-asarone is clearly carcinogenic and has proposed limits for its concentration in flavorings such as bitters made from Acorus calamus (Sweet Flag).[9]
