Will eating Illicium always cause poisoning?

Under normal circumstances, consuming star anise (Illicium verum) may lead to poisoning symptoms because it contains natural toxic components. However, in rare cases where only a very small amount is accidentally ingested and the individual has strong metabolic capacity, obvious discomfort may not appear immediately—this does not mean poisoning will definitely not occur. If ingestion occurs, medical consultation is recommended without delay. Detailed analysis is as follows:

Star anise contains toxic substances such as anisatin and illicin. Once ingested, these components can irritate the gastrointestinal mucosa and potentially affect nervous system function, leading to poisoning symptoms including nausea, vomiting, abdominal pain, dizziness, and convulsions. Even small amounts (such as several grams of fruit or leaves) can cause discomfort in most people due to accumulation of the toxins. The onset time of poisoning symptoms correlates with the ingested dose—the larger the amount consumed, the faster and more severe the symptoms.

In extremely rare cases, if only trace amounts of star anise powder are accidentally contacted (e.g., adhering to food surfaces), and the individual has strong liver metabolism, there may be no immediate noticeable symptoms. However, this does not mean the toxins have had no effect on the body. Toxic components may still accumulate internally or gradually cause adverse effects during metabolism. This situation should not be interpreted as "non-toxic" or "safe," and close monitoring of physical condition remains necessary.

Once accidental ingestion of star anise is suspected, regardless of whether symptoms are present, individuals should promptly bring a sample of the plant to a healthcare facility for evaluation to avoid delays in treatment. In daily life, care should be taken to distinguish star anise from edible plants (such as common star anise used in cooking) to prevent risks associated with mistaken collection or consumption.
