Erucic Acid-Both Sides of the Story: A Concise Review on Its Beneficial and Toxic Properties

Erucic acid (EA) is monounsaturated fatty acid (22:1 n-9), synthesized in the seeds of many plants from the Brassicaceae family, with Brassica napus, B. rapa, or B. carinata considered as its richest source. As the compound has been blamed for the poisoning effect in Toxic Oil Syndrome, and some data indicated its cardiotoxicity to rats, EA has been for decades classified as toxic substance, the use of which should be avoided. However, the cardiac adverse effects of EA have not been confirmed in humans, and the experiments in animal models had many limitations. Thus, the aim of this review was to present the results of the so far published studies on both toxic, and pharmacological properties of EA, trying to answer the question on its future medicinal use. Despite the ambiguous and relatively small data on toxic and beneficial effects of EA it seems that the compound is worth investigating. Further research should be particularly directed at the verification EA toxicity, more in-depth studies on its neuroprotective and cytotoxic properties, but also its use in combination with other drugs, as well as its role as a drug carrier.

Automated summary

Erucic acid (EA) is a monounsaturated fatty acid found in the seeds of various plants. While studies have suggested that EA may be cardiotoxic to rats, its effects on humans have not been confirmed. This review aims to summarize the current research on the toxic and pharmacological properties of EA, in order to determine its potential medicinal use.
