The US Food and Drug Administration (FDA) has issued a warning to food manufacturers and consumers about Amanita muscaria, a fungus that can have hallucinogenic effects. The agency has concluded that the use of this ingredient and its constituents is not safe for human consumption and may be harmful. Despite its potential benefits in traditional medicine, A. muscaria does not meet the safety standard for use in food and should be avoided by consumers. The FDA will continue to monitor the use of this ingredient in foods and dietary supplements, encouraging manufacturers to ensure their products meet safety standards.
