Myrcene is not considered highly toxic, but it can exhibit mild toxicity at elevated levels. Studies have shown that large doses of myrcene may lead to adverse effects such as gastrointestinal discomfort and irritation. In animal studies, very high doses have been associated with liver damage, although such doses are not typically encountered in everyday human exposure scenarios. Furthermore, while myrcene has not been classified as a carcinogen, its potential to enhance the absorption of other compounds, particularly those that may be harmful, warrants cautious use. This property of myrcene can lead to increased exposure to harmful substances, raising concerns about its role as a facilitator of toxicity in specific contexts.
